  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Composite materials are increasingly used in a broad range of applications due to their recognizable mechanical properties and the high strength-to-weight ratio. The aim of the current study is to improve the mechanical properties and fracture toughness of composite laminates. Several types of fabrics, such as glass, carbon, and Kevlar, and micro-particles are adopted to create composite laminates via the vacuum infusion method. The mechanical performances of the proposed laminates were evaluated via tensile and flexural strength tests. Moreover, the impact strength tests were conducted to examine their dynamic performances. Results showed that woven laminates such as glass woven, carbon woven, and Kevlar woven composites with micro-particles revealed better tensile properties compared with those without micro-particles. For instance, enhancement in the Young’s modulus with around 5%, 6%, and 13% were resulted from the glass, carbon, and Kevlar fabrics with fillers, respectively. Furthermore, higher impact strength and fracture toughness were obtained from the laminates of glass, carbon and Kevlar with inclusion of thermoplastic particles. For example, the glass, carbon and Kevlar fabrics composites with fillers samples showed improvement in the fracture toughness with around 24%, 17% and 14%, respectively. In addition, numerical simulation findings of flexural failure load and damage failure modes were in accordance with experimental results both qualitatively and quantitatively.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Warp-knitted spacer fabrics (WKSF), with their unique structure and excellent energy absorption properties, are widely utilized in the automotive industry, medical field, and aerospace sectors. However, during practical applications, WKSF undergo repeated compression, which can lead to compressive fatigue of the spacer yarns and consequently cause the WKSF to undergo irreversible deformation, which subsequently affects its performance and appearance. Therefore, to enhance the compressive properties of WKSF and investigate the mechanisms of plastic failure, this study used a warp knitting double needle bar raschel machine to fabricate a WKSF with a thickness of 20 mm. Through fabric structure analysis, we developed a unit cell model consisting of 32 fibers and a more comprehensive analysis model with 320 fibers to quantitatively assess the geometric changes of the WKSF during the compression process. Furthermore, we experimentally studied the performance changes of the WKSF under different compression speeds, various compression strains, and 1000 cycles of loading. By integrating experimental test with the finite element method, we have conducted an in-depth study of the compression process of WKSF, simulating the displacement U, Von Mises stress distribution, and plastic compression failure behavior during compression. By comparing data on Von Mises stress, equivalent plastic strain (PEEQ), and energy density distribution (SENER), we can clearly observe the performance of spacer yarns under compression conditions, providing significant insights into the underlying plastic failure mechanisms of WKSF’s. This study not only enriches the theoretical framework for WKSF compression but also lays a solid foundation for improving its performance and extending its applications.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Thermal protection systems (TPS) are vital for re-entry vehicles for their safe passage into the atmosphere from space. Hence, researchers took a keen interest in improving the thermal and ablative properties of composites to be used in making thermal protection systems. Therefore, an attempt was made to improve the thermal and ablative properties of composites made of carbon fibers (Cf) and resorcinol formaldehyde phenolic (Ph) resin with the incorporation of silicon carbide (SiC) particles. The filler was added in various percentages (0 wt% - blank, 1 wt%, 3 wt%, and 5 wt%), and the composites were tested for ablative, thermal and mechanical properties. The results demonstrate that the SiC-modified PAN-based carbon fiber reinforced phenolic (SiC-PANCf-Ph) composite with 3 wt% SiC enhancement exhibited ideal properties. The post-ablation phase composition and microstructure were examined through X-ray diffraction (XRD), Scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). The surface morphology evidences the formation of a silicon dioxide (SiO2) layer on the composites. The SiC-PANCf-Ph composites demonstrated the lowest ablation rate, enhancing their potentiality for effective TPS applications.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  This study explores the mechanical and thermal characterization of epoxy-based composites reinforced with chemically modified woven cotton fabrics using the resin infusion technique. The woven fabrics construction parameters were varied in terms of weft yarn counts (16, 20, and 24 Tex) and pick densities as defined by pick wheel teeth (PWT) (30, 36, and 41 T). The fabrics were surface treated with 6% concentration of sodium hydroxide (NaOH) using the alkali treatment method. The obtained results revealed that mechanical strength improved with decreasing weft yarn count and increasing PWT. Notably, chemically treated composites with the highest PWT exhibited superior strength compared to untreated counterparts, attributed to more compact microstructures, reduced fabric/fiber breakages, and enhanced interfacial bonding between the reinforced plain-woven cotton fabric and epoxy matrix. Thermogravimetric analysis (TGA) showed that all composites have higher thermal stability above 300°C, with untreated fabric composites exhibiting the highest resistance to degradation, whereas the treated composite quickly degraded at an onset temperature of 288.4°C due to the removal of the hemicellulose, decomposition of the cellulose, and lignin content. In conclusion, the study indicates that surface treatment and woven construction parameters such as weft yarn counts and pick wheel teeth, as well as the resin infusion technique, significantly influence the mechanical, microstructural, and thermal properties of resin-infused woven cotton reinforced composites for potential application in industrial and automotive sectors, offering lightweight, durable solutions for components such as construction and building panels, doors, and roof panels.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  According to recent studies, user comfort is one of the major challenges faced regarding the vehicle seating. The outer upholstery layer of the seat cover is the main factor contributing to overall user discomfort in the driving environment. This is related to the limitations of the conventional fabrics used. Therefore, alternative textile materials for seat covering are being increasingly sought out. In this work, we propose innovative shape memory-based seat covering fabrics offering improved comfort properties. Shape memory polyurethane (SMPU) multifilament yarns were combined with polyester (PES) yarns to produce three types of woven fabrics having the typical structures used in seat coverings (plain, twill 2/2 and derived twill) using a fixed warp and weft ratio of 3PES:1SMPU. The effects of SMPU yarns on the physical characteristics of the fabrics (thickness, areal weight, yarn density, and tightness) as well as on their mechanical behavior, shape memory effect, thermal comfort, and abrasion resistance under similar usage conditions in car seat covers were investigated. Improvement was observed in the ergonomic comfort with maintained thermal comfort in the presence of SMPU multifilament yarns, with this effect being more noticeable in the twill fabrics. The thermodynamic SMPU-based fabrics used in this study could be potential candidates for use in seat upholstery given the improvement in user comfort over extended use.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  This research aimed to create a UV sensor using photochromic pigment in nonwoven form and analyse its fatigue resistance under continuous ultraviolet (UV) light. The photochromic polymeric matrices consist of a photochromic pigment, a polymer, and a photo stabilizer, which enhance the stability of the photochromic systems under light exposure. As a base matrix, we used polyvinyl butyral. Then, we added different amounts of the photochromic pigment 5-chloro-1,3,3-trimethylspiro [indoline-2,3′-(3H) naphtho (2,1-b) (1,4)-oxazine]. We produce photochromic nonwovens by electrospinning a polymeric matrix solution with varying pigment concentrations. The study aimed to create a UV sensor with photochromic nanofibers that are very sensitive to light. It also tested how well it can degrade under continuous UV radiation by looking at its photo fatigue resistance under constant UV irradiation for its final use as a UV sensor material. Using FTIR, CRM, SEM, and XRD techniques, this study investigates the physiochemical properties and photodegradation behaviour of photochromic nonwovens and writes a report on it. The photo-light stability of photochromic materials is a major problem concerning its external stimuli in different substrate forms. It also looks at how well they resist photo-chemically towards the UV light. The fatigue resistance measurements were carried out using a FOTOCHROM3 spectrophotometer under continuous UV irradiance using two different modes. This study evaluated and reported their photodegradation behaviour in cyclic and continuous UV irradiance modes. The tests showed that the prepared photochromic system works well with photostability and can go through more than 20 exposure cycles, each with 100 min of UV light and intensity equal to 1/3 of the sun’s rays on a clear day. Given the PVB applications in our daily lives, it can serve as a UV sensor in numerous industrial applications. Photochromic nanofibers possessing excellent photosensitivity hold immense promise as optical rewritable devices and colourimetric-based UV sensors.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  This study aims to validate the optimal posture for the Dumbbell Biceps Curl (DBC) exercise using Textile stretch sensors and Surface Electromyography (sEMG), and then detect inaccurate posture using a Sparse Autoencoder. To validate the optimal DBC exercise posture, we measured the effects of wrist supination and the angle of the upper body and elbow on the biceps and forearm muscles. A wrist sleeve-shaped Textile stretch sensor detects wrist supination, and sEMG measures biceps and forearm muscle activation. The experiment results confirmed that an angle between the upper body and the elbow within 90°, coupled with wrist supination, constitutes the most efficient posture, maximizing the activation of the biceps while minimizing the synergistic effects of the forearm muscles. Subsequently, this posture was learned through a Sparse Autoencoder, and the Root Mean Square Error values of the trained model were lowest in the optimal posture (Biceps: 0.090, Forearm: 0.076). This suggests that Sparse Autoencoder could be useful in identifying inaccurate exercise postures. In summary, this study aims to develop an exercise posture feedback system through the integration of modern exercise physiology and technology, particularly the fusion of AI and sensor technology. The goal is to propose the potential to detect and correct inaccurate or unsafe exercise postures.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Respiratory measurement is a crucial indicator for assessing health status; however, current methods for measuring respiratory rate and frequency are passive and not intuitive. This study investigates peak detection algorithms using a resistive strain sensor integrated into a garment for respiratory rate monitoring. The sensor, constructed with CNT material and a flexible rubber substrate, exhibits high conformity to the body’s contours. Designed for respiration measurement, the sensor maintains a low 6% strain for optimal sensitivity, demonstrating a 4% decrease after 800 repetitions of 10% elongation. Garment design emphasizes cohesion between the sensor and fabric, achieved through a piping technique. Respiratory measurement relies on a resistive sensor principle, where abdominal volume changes induce tension, altering resistance. Three peak detection algorithms are evaluated: the window size algorithm, low-pass filter, and FIR filter. The window size algorithm shows a 93% matching rate for normal breathing but requires manual adjustments based on breathing speed. The low-pass filter reduces noise but introduces lag, challenging peak matching. The FIR filter effectively detects peaks at increased speeds, achieving a matching rate exceeding 98%. The study concludes that the choice of algorithm depends on respiratory scenarios, with the window size algorithm suitable for regular cycles, the low-pass filter for real-time monitoring, and the FIR filter for accelerated respiratory rates. The study primarily explores static situations, indicating the need for future research on dynamic respiratory movements to enhance algorithm versatility.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  This study proposes the use of a CNN model to predict the resistance of conductive fabrics by utilizing the brightness information from their images, aiming to address the limitations of traditional contact-based measurement methods and explore the feasibility of non-contact resistance measurement. Conductive fabrics were produced using environmentally friendly cellulose fiber as a base material, with a dip-coating and padding process involving water-based single-walled carbon nanotube (SWCNT). After scanning the produced conductive fabrics and meticulously preprocessing the images, a dataset for CNN training was constructed, comprising label values corresponding to the sheet resistance of each image. ANOVA analysis confirmed a statistically significant relationship (p-value = 8.04145e^-18) between the brightness of conductive fabric images and their sheet resistance. By leveraging the relationship between the brightness of fabric images and sheet resistance, training of the CNN model yielded an RMSE of 0.0558 and an R-squared value of 0.9557, validating the effectiveness of the designed CNN model for image-based resistance prediction. This research is expected to contribute to the development of future real-time monitoring and control systems, providing a crucial foundation for the advancement of data-driven measurement and control systems based on computer vision and machine learning techniques. Furthermore, it is anticipated to unveil new possibilities for various applications of conductive fabrics.

  A high purity Ni plating layer was obtained on the surface of the plain cotton fabric by electroless nickel plating. The micromorphology and elemental composition of the Ni plating layer were characterized by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). Structural absorbing composites with glass fiber (GFs)/epoxy resin (EP) as permeable layer, nickel coated fabric/EP as absorbing layer and carbon fiber UD cloth (UDCFs)/EP as reflecting layer were prepared by vacuum assisted resin perfusion (VARI). The effects of different thicknesses on the microwave absorption properties and mechanical properties of composites were investigated. The results show that the lowest reflection loss (RL) is −31.02 dB, the effective absorbing bandwidth (RL < −10 dB) is 6.21 GHz (11.55 GHz - 17.76 GHz), and the maximum tensile and bending loads endured are 41.36 KN and 1.63 KN at 15.14 GHz with a thickness of 2.5 mm, which provides a good reference value for the subsequent preparation of magnetic/dielectric composites with both excellent microwave absorption and mechanical properties.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Modern science and technology constantly require new and novel materials with special properties. Over the past decade, Nanocomposites materials have received significant attention as active materials in components ranging from sensors to biomaterials, electronics devices to structural parts. These novel composites have applications in many areas, such as energy, insulation, manufacturing, and the modern building industry. However, not all applications have the same requirements in terms of acoustic insulation, so it is useful to adapt the kind of core materials and their product specifications, such as particle size and porosity, to the different applications. Furthermore, in some applications, cheaper core materials, like precipitated silica, would be a reasonable alternative to replace the time-consuming series of measurements. Because of many bad conditions that affect acoustic insulation properties in modern buildings. And to summarize recent applications of nanotechnology as they relate to textile fibers, yarns, and fabrics for improving acoustic insulation in modern buildings and civilian communities, this paper discusses the ability to apply 3D woven spacer fabric (3DWSF) composite materials reinforced with epoxy, rigid polyurethane foam, and silica nanoporous particles, which were prepared by the sol-gel technique. Four samples had been prepared, all of these samples were textile composite materials, and reinforced with two types of nano silica 99.8% SiO2; mesoporous Ns particles with porosity up to 83%, true density 0.08 g/cm³, and particle size between 100 and 2000 nm and pore size 70–150 nm, which had been prepared by Sol-gel technique, and nonporous Aerosil®200 particles with surface area 200–225 m2/g, true density 0.25 g/cm³, and particle size between 2 and 20 nm. We used rigid polyurethane foam as core material, and epoxy resin for laminating the fabric. 3D spacer E-glass fabrics, and chopped E-glass microfibers had been used. The weight percentage of silica nano particles which were used in this research was 5% by weight, which was better for economic reasons, and enough, to enhance the acoustic absorption coefficient up to [math] = 99.79%. The best sound absorption could be achieved by using mesoporous silica nanoparticles, and soundproofing of an insulator using this porous structure is better than using a nonporous one. We found in this research that the thickness 45 mm and semi-porosity structure of the 3DWSF composite insulator material were enough to make a difference, with reference to the thermal and acoustic insulation guide of buildings.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Workwear clothing is one of the essential personal protective equipment for workers and plays a crucial role in preventing the entry of environmental heat into the body and facilitating thermal exchanges between the human body and the environment. Improving the coating of workwear fabrics while maintaining air permeability is considered an engineering control measure to protect workers in environments with thermal stress. This study aimed to optimize the coating of workwear fabrics with TiO2 nanoparticles to enhance thermal insulation properties and air permeability using the response surface methodology (RSM) and MATLAB. The input variables were the titanium isopropoxide volume and reaction time in the ultrasonic, while the output variables were the coating percent, air permeability, and thermal conductivity coefficients. The morphology of TiO2 nanoparticle and coated fabric (FE-SEM, EDS, FTIR, FTIR-ATR, DLS, and XRD), The intrinsic properties of fabrics (Yarn Count, Abrasion Resistance, Tensile, Tearing Strength), the Water Vapor permeability, Surface wetting resistance, and Durability test were evaluated according to the standard methods. No significant differences were observed in the intrinsic properties between the coated and uncoated fabrics. Increasing the coating percent of fabrics with TiO2 nanoparticles was accompanied with a decrease in the thermal conductivity coefficient and an increase in air permeability. The positive effect of nanoparticle coating is a significant step towards introducing a new generation of smart textiles with the potential to improve thermal insulation properties while maintaining air permeability. This advancement aims to preserve and enhance the health and safety of workers exposed to thermal stress.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  The increasing demand for durable, eco-friendly clothing has led to the use of nanomaterials in textiles. However, concerns arise about the impact of engineered nanomaterials (ENMs). Studies have explored nanoparticle release from textiles during usage and washing. However, the existing data is fragmented, and a comprehensive grasp is absent. A systematic review is required to consolidate existing evidence and offer a thorough analysis of nanoparticle release from nano-enhanced textiles in commercial use and washing. This review assess the research aims to concerning the release of nanomaterials from commercial textiles during usage and laundering. The process involved defining objectives, crafting a search strategy, utilizing databases, and applying inclusion/exclusion criteria. After deduplication, articles were screened for eligibility, covering nanoparticle characteristics and release mechanisms. Searches spanned Scopus, PubMed, and Web of Science, using keywords like “Nano,” “Nanoparticles,” etc. Original articles on nanomaterial release from conventional textiles were included. Out of 1549 articles identified, and met the criteria for inclusion in the study. The results reveal that textiles employing nanotechnology can indeed release a significant quantity of nanoparticles. The characteristics of these released particles, including their quantity and composition, are influenced by various factors such as nanoparticle structure, adhesive properties, fabric type, and environmental interactions. While there exist variations between laboratory simulations and real-world conditions, these findings underscore potential risks associated with nanoparticle release, underscoring the necessity for toxicological assessments and additional research into particle behavior, particularly emphasizing the functional aspects of fibers and the environmental impact following nanoparticle release after washing.

In view of the present situation of smart wear used in clothing comfort research, this paper primarily presents the construction of an acquisition system in motion, including temperature, humidity, and pressure data acquisition device, data pre-processing, data storage, and so on, which was called the ATHPD system for short. With the help of this acquisition system, tights in motion may now be tested for pressure, heat, and humidity for the first time. It can also transmit data wirelessly. Meanwhile, in order to verify the effectiveness of the acquisition system, by comparing the measurement data of the acquisition system (ATHPD system) with the measurement data of existing acquisition equipment (AMI3037 pressure measurement system, DS1923 button temperature and humidity recorder). The findings demonstrate that there is no significant difference between the data collected by the two methods, which proves the reliability of the acquisition system in this paper. The system guarantees the same quantity of temperature, humidity, and pressure data to be gathered at the same time and the consistency of the corresponding time points and also provides relevant data support for the evaluation and prediction model construction of human comfort in motion.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  The use of 3D printers is expanding across various industries. The incorporation of reinforcing fibers and structures, such as negative Poisson, has the potential to enhance the mechanical properties of three-dimensional products. In this study, a specialized nozzle is developed for 3D Fused Deposition Modeling (FDM) printers dedicated to the production of continuous fiber-reinforced thermoplastic (CFRT) composites. The primary objective is to enhance the tensile strength and impact resistance of 3D-printed samples. It is achieved through the investigation of strategies such as fiber reinforcement, variation in the number of fibers within the reinforcing yarn, and the creation of samples featuring an internal structure with a negative Poisson’s ratio (NPRS). In this regard, four types of 3D samples are prepared including polymer only, polymer with a negative Poisson’s ratio structure, polymer reinforced with continuous fibers (glass and carbon fibers), and polymer reinforced with continuous fibers featuring a negative Poisson’s ratio structure. The mechanical properties of these samples, including tensile strength and impact resistance, are also compared. The results indicate that incorporating fibers as reinforcement can enhance the mechanical properties of 3D-printed products. Moreover, continuous fibers with more fibers within the same yarn count have an increased strengthening effect. The use of negative Poisson structures significantly improves impact resistance but adversely affects tensile strength.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  With the popularity of sports and fitness, the chances of sports injuries for people have increased. Orthopedic sutures play an important role in the treatment of musculoskeletal disorders. Ultra-high molecular weight polyethylene (UHMWPE) yarns, with excellent tensile, compressive, impact strength, abrasion resistance, and chemical stability, are competitive materials for the preparation of sutures, but the tensile properties of sutures in knotted and wet environments are more informative in practical applications. In this paper, the effects of different structural parameters, knotting methods, and environments on the physical properties of nonabsorbable UHMWPE sutures, including appearance, breaking force, and breaking elongation, were investigated. The results showed that sutures with circular cross-sections had the best tensile properties; the loop knot gave the suture the greatest breaking strength, but also the smallest elongation, and the more complex the knot, the greater the elongation of the suture; dry and wet conditions have a significant effect on the mechanical properties of sutures. It is expected that this study will provide theoretical support for the optimal design of sutures and provide a basis for doctors to choose the knotting method.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Recycled fibers obtained from pre-textile waste present advantages and challenges in acoustic absorber design. This study examines the potential of incorporating textile waste into acoustic absorption systems, with a focus on pre-used waste, to increase the percentage of recycled fibers in the textile industry using the quantitative method Used to evaluate the efficiency of panels manufactured in different sound frequencies, from up to 2000 Hz, and, in some cases, up to 3000 Hz Observations indicate that surface cleaning products, pneumafil waste a twist, comb bat residue and waste grinders exhibit the highest sound absorption coefficients in and using waste samples In addition, a procedure has been developed to evaluate the sound absorption reduction coefficient, which exposes high correlations with values obtained by other methods Sound contour mapping further confirms the homogeneity of the sample and reveals the effectiveness of specific sound absorption systems, such as air condition station filters, spinning pneumafil waste, and weaving waste (samples 18, 20, 21, and 23). Nevertheless, the study of integration emphasizes the ability to reuse waste fibers for sound insulation that can absorb adequate sound, reduce reflected sound, and offer a promising solution for dealing with noise pollution. A thorough examination of sound contour maps across absorber surfaces is undertaken to account for the material structure of the absorber, ensuring an accurate representation of how sound is absorbed and distributed within the designated area.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Geotextiles, as a type of common filtration material, have broad prospects in emergency rescue of dike backward erosion piping (BEP). To investigate the filtration performance of geotextile in BEP emergency rescue, several experiments were conducted using nonwoven and woven geotextiles to simulate the process of rescuing BEP with geotextiles. The influence of geotextile specifications and types on hydraulic compatibility of the filter system was analyzed, and the clogging mechanism of geotextile during dealing with BEP was revealed at a microscopic level. The results showed that the nonwoven geotextile filter with an equivalent pore size of 0.103 mm had a gradient ratio value of less than 3, and it had a highest flow rate of 260 mL/min. Increasing the thickness and pore size of nonwoven geotextiles within a certain range helped enhance their anti-clogging ability. The main mechanism of clogging in nonwoven geotextiles was the deposition of fine sand particles on their surface, forming a layer of low permeability soil. Plain woven geotextiles experienced severe clogging with a 42% reduction in flow rate, and it was not suitable for rescuing BEP. The clogging mechanism of woven geotextile involved the blocking of horizontal water passages by fine sand particles.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Tailoring the surface morphology of nanofibers determines its application to an excessive extent. At present, different structures of nanofibers have been produced such as wrinkled, grooved, porous, rough, etc. Amongst them, wrinkled nanofibers have attracted the attention of researchers due to their exceptional structure and properties such as coarse surface, high surface energy, high specific surface area, excellent mechanical properties, and good piezoelectricity resulting in serving successfully in various fields such as energy harvesting, air filtration, water filtration, gas sensors, biomedical applications, fuel cells, and energy storage. Therefore, this work aims to spotlight the importance of the wrinkled structure, methods, and strategies used for producing electrospun wrinkled nanofibers of various materials. This review focuses on the materials, preparation methods, and applications of the electrospun wrinkled nanofibers. This review can serve as an essential reference for the materials, formation methods, and applications of wrinkled nanofibers prepared via electrospinning.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  The textile industry contributes significantly to global warming and pollution, especially the leather industry, which uses livestock and toxic tanning processes that have a great environmental impact. Currently, efforts are being made to mitigate the negative impacts of the textile industry by using alternative non-toxic chemicals or by recycling fabric. More recent efforts explore utilization of non-conventional biomaterials and organisms, such as mushroom mycelia, algae or genetically-engineered microorganisms. In this study, we implemented slime mold Physarum polycephalum perfused through leather-like fabrics made from air-dried simple nutritious media in order to develop environmentally friendly, easy-to-manufacture and sustainable fabrics. Plasmodium was validated for its viability and propagation under non-sterile conditions and in contaminated environments on different media compositions made from agar, peach gum, gelatin, carrageenan or glycerol. We determined optimal media components to be agar, gelatin and glycerol which supported plasmodium growth and yielded sturdy and flexible fabric sheets after air-drying. Ultimately, plasmodium-perfused fabric sheets were sewed into apparel and footwear. This study demonstrates the use of simple media as a clothing fabric perfused with plasmodium, which produces intricate colors and patterns on the fabric. Plasmodium has the ability to enhance fabric properties due to its natural problem-solving abilities, such as biosensing, fabric self-repair, and distant fabric communication.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Three-dimensional (3D) woven and knitted spacer fabrics have emerged as significant advancements in the field of technical textiles, driven by notable progress made by the textile industry. These unique fabrics possess desirable characteristics that render them suitable for various technical applications. As we look towards the future, spacer fabrics are expected to find innovative applications in various functional products. However, despite the growing interest in their use in the technical textile sector, comprehensive reviews exploring their potential are lacking. Therefore, this review aims to fill this gap in the existing literature by examining the potential of 3D woven and knitted spacer fabrics in technical textiles. It provides a comprehensive exploration of their fabrication techniques, properties, key parameters, and potential applications in technical textiles. This review highlights that woven spacer fabrics exhibit high integrity and stability, making them suitable for composite reinforcement. On the other hand, knitted spacer fabrics offer a higher air-trapping capacity and a double-faced nature, leading to their extensive use in cushions, medical textiles, and protective technical textiles. Additionally, this review provides valuable insights for researchers and manufacturers interested in harnessing the potential of spacer fabrics for various functional products in the field of technical textiles.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Commercial facemasks have become a common tool during the COVID-19 pandemic. They are cheap, simple to use and some are capable of filtering out most particles in the air, protecting the user. These qualities are usually employed in relation to hurtful viruses or contaminants, but they could also be used to prevent the radioactive dose due to radon, which is the second leading cause of lung cancer worldwide. For that reason, the main goal of this study is to verify if facemasks could prevent radon decay products from entering the potential user’s lungs. Since these decay products are the main source of radioactive dose, several commercial facemasks were tested by exposing them to radon and then measuring the presence of radon daughters by gamma spectroscopy. Reusable facemasks made from materials such as cotton, polyester or neoprene appeared to be inefficient with only 40% filtering efficiency, Polypropylene woven masks being the only exception, with 80% efficiency. Surgical masks presented filtering efficiencies between 90 and 98%. FFP3 and FFP2 proved to be the most reliable, almost completely filtering out radon daughters with filtering efficiencies up to 98%. Results prove that the use of FFP3 and FFP2 facemasks could be a useful tool to reduce the radioactive dose due to radon in places where other techniques cannot be used or are not advisable.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  In this study, antimicrobial and deodorizing nanofibrous composite membranes based on natural substances were developed for use in feminine sanitary napkins. Plant-derived natural essential oils, such as lemongrass oil and May Chang oil, were incorporated into polyvinyl alcohol nanofibers using emulsion electrospinning. The fiber morphology, oil distribution, and pore size distribution of the nanofibrous composite membranes were examined. The antimicrobial and deodorizing effects, tensile properties, and release behavior of the functional ingredients from the composite membranes were investigated to examine their use in sanitary napkins. Core–sheath nanofibers, in which lemongrass oil or May Chang oil was uniformly distributed within the fiber core, were fabricated using various oil contents. The essential oil-loaded nanofibrous composite membranes contained pores ranging from 0.130 to 1.349 µm in size. The release profiles of the essential oils from the composite membranes over an 8 h period demonstrated a continuous release of citral and limonene. Composite membranes containing either lemongrass oil or May Chang oil exhibited outstanding antimicrobial effects against vaginal pathogens, such as Candida albicans and Staphylococcus aureus, despite their low oil content. Deodorizing effects against ammonia gas were observed at oil contents higher than that required to achieve antimicrobial effects. The composite membranes exhibited lower Young’s modulus and greater elongation at break values under wet conditions compared to dry conditions. Our findings demonstrate that antimicrobial and deodorizing nanofibrous composite membranes based on plant-derived essential oils have the potential for use in feminine hygiene products.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  The study aims to provide valuable insights into the development of sustainable and cost-effective composite materials, particularly focusing on the combination of palm fiber and jute fabric. The inclusion of palm fibers significantly enhances the stiffness and strength of the composite. The research involves the fabrication of composites with a consistent fiber-to-polymer ratio of 20% in all samples. However, the proportions of the various reinforcing components varied in each sample, with the palm fiber ratio to jute fabric set at 40%, 70%, and 100%. The resulting curved beam, designed as a low-speed collision bumper, surpasses its commercial counterparts in deflection. Increasing fiber volume percentages contribute to enhanced bending stiffness and flexural strength. Notably, the optimal ratio of 70% demonstrates the highest impact energy, surpassing the 40% ratio sample by 150%. The study underscores the successful production of a low-impact bumper through the synergistic reinforcement of jute and palm fibers. It emphasizes the specific optimal ratio (70%) as a substantial contribution to the sustainable development of composites for effective low-impact bumpers.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  To utilize the human body heat to trigger the shape memory smart textiles, shape memory polyurethane filaments (SMPUF) with three different transition temperatures were prepared based on modified polycaprolactone diol (PCL) by dry spinning. The chemical structure was characterized systemically. The shape memory properties, tensile properties, resilience, and viscoelasticity were studied comprehensively. The results revealed that the phase transition temperatures were close to human body temperature which measured 19.97°C, 27.33°C, and 30.37°C, respectively. Additionally, the fraction of hydrogen bonds in the samples was about 30% less than that of polyurethane filaments (PUF). The best shape fixity ratio was 88.5% and the shape recovery ratio was 96.7% belonging to samples with a transition temperature of 30.37°C. At 55°C, the elastic recovery was 45.2% higher than that at 22°C. As the temperature rose, the elastic modulus of SMPUF decreased until it reached that of PUF. The static and dynamic viscoelasticity of SMPUF indicated that the phase transition of the soft segment affects the movement of the molecular chain. SMPUF can be used as compression garments, and wearable orthopedic devices, such as the elastic bands prepared in this work.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Shape memory alloys (SMAs) have an innate property that allows them to return to a memorized form when stimulated. They have been recently designed as flexible fabrics for use in wearable assistive devices. This study aimed to develop a rehabilitation assistive glove with good wearability for a hemiplegic patient using a knitted SMA with a high-unidirectional contractile response. We fabricated warp-knitted SMA actuators, which had higher contractile responses than those of weft-knitted SMA. The use of a knitting loom allowed these actuators to fit all the fingers of a patient. We developed a full-fabric glove, placed the SMA wires on the finger regions to form a tendon-driven structure, and attached knitted SMA actuators to the dorsal and palmar sides of the hand to assist flexion and extension. The joint range of motion after glove actuation increased by 11.620% and 141.710% in flexion and extension, respectively. The range of motion improved more with glove rehabilitation than with thermal stimulation or no actuation. The grip force also increased by 52.400% after rehabilitation exercises. The safety of the heat generated during actuation was confirmed, and its applicability as a thermal stimulus was validated (based on increased skin temperature). These outcomes suggest the practical potential of warp-knitted SMAs in fully fabricated wearable assistive devices.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  In this paper, a new type of core-spun compound aramid yarn has been applied in the construction of UD fabric to investigate if the ballistic performance of the whole fabric could be positively influenced. Three types of fabrics (Fa, Fb and Fc) herein have been developed. Fa is the traditional type of UD fabric with two layers laying at the angle of 0°/90°. Fb is made by adding new CSC aramid yarns inside of Fa at the angle of 0°/90°. Fc is further developed from Fb via changing yarn-ply directions as 45°/-45°, to analyze if the yarn-ply directions would influence on the ballistic performance of new UD fabric. The result is quite positive, as it shows that Fb and Fc have apparent energy absorption capability than Fa, and Fc is the best. This indicates that the introduction of core-spun compound aramid yarns could indeed improve the ballistic performance of UD fabric, and the yarn-ply direction of 45°/-45° is better than that of 0°/90° to absorb more energy. This research has been investigated with the assistance of both the ballistic test and the FEA model. Energy absorption and penetration resistance mechanism are the two major aspects to analyze to reflect the ballistic performance of these fabrics.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  This paper studies the influence of the weave parameter on the ballistic performance of multi-ply systems. Three types of plain weaves were put into investigation, namely, A090, A200, and A400. Tensile and yarn pull-out tests were performed to investigate the responses of fabric upon quasi-static loading. Penetration tests were performed to characterize the energy absorption capability of different multi-ply systems at impacting velocities ranging from 250 m/s to 460 m/s. It was found that the strength of the fabric sample increased almost linearly with fabric areal density, and the coarser weaves exhibited a greater resistance against yarn pull-out. The ballistic limit (V50) of finer weave 13A9, is around than 42.5% higher than coarser weave 3A4. In terms of hybrid systems, placing finer fabrics in front and coarser fabrics in the rear exhibits higher ballistic limits than the reversed sequence (8–20 m/s differences), while placing coarser fabrics in front exhibited greater energy absorption capability when the impact velocity is sufficient to cause instant and localized failure. It was also found that the ballistic performance of the hybrid systems does not alter significantly with the mass percentage of the coarser weaves at high impact velocities (greater than 400 m/s). The results indicate that replacing the expensive ballistic weaves with cheap materials in a hybrid system is a reasonable alternative to achieve cost reduction without significant performance degradation.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  A sandwich insulation wall panel is a novel composite wall that integrates load bearing, thermal insulation and decoration. Most of the wall materials of sandwich insulation wall panels are made of ordinary concrete or lightweight concrete, which causes the wall panels to be too thick and heavy, and there are problems associated with poor durability and high energy consumption. Textile-reinforced engineered cementitious composite (TRE) materials have excellent mechanical properties, toughness and durability. Therefore, a type of sandwich insulation wall panel (SIWP) was constructed using textile-reinforced engineered cementitious composites (TRE) as the inner and outer wythes. Its good crack control ability and tensile performance can compensate for the brittle cracking and shedding of ordinary concrete sandwich insulation wall panels. Through a four-point bending test, the bending performance of the TRE sandwich insulation wall panel (TRE-SIWP) was analyzed from three aspects: failure mode, load-midspan deflection curve and ductility. The research variables included the number of hot rain cycles, the thickness of the TRE wythes, the hot rain environment, the thermal insulation layer type and thickness, and the number of heating-freezing cycles. The results show the that hot-rain cycles had the least effect on the specimen with a rock wool board, and they caused more damage to the TRE wythes than they did to the insulation board. Increasing the thickness of the insulation layer and TRE width could improve the flexural bearing capacity and stiffness of the TRE-SIWPs.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  The thermal conductivities of woven composites are strongly affected by the anisotropic properties of the reinforcing fibers, and thus by the fabric structure. In this study, the thermal conductivity of 2D woven composites was investigated by optimizing the fabric structures to enhance the through-thickness and in-plane thermal conductivities. Multiscale finite element models were developed to simulate the thermal behavior of various 2D fabric structures and evaluate their thermal performance under varying conditions, focusing on the effects of fiber tow undulation, dry-zone porosity, and matrix-rich zones. Fabric architectures were selected based on common 2D weavings of composites. The results showed that the tow undulation substantially enhanced the through-thickness conductivity and mitigated the impact of porosity. In addition, a higher tow anisotropy increased the effect of undulation. Moreover, the plain-weave fabric structures exhibited the highest through-thickness and in-plane thermal conductivities among the evaluated 2D woven fabrics in porous composites. Finally, the matrix-rich zones showed a stronger effect on the through-thickness than on the in-plane thermal conductivity of the 2D woven composites.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  This article aims to investigate the dynamic behavior of high-performance multi-axial warp-knitted flexible composite materials under low-velocity impact tests through experiments and numerical simulations. In this paper, high-performance multi-axial warp-knitted flexible composites were prepared. Three different preparation processes, 175°C-5 min, 185°C-10 min, and 195°C-15 min, were designed for the multi-axial warp-knitted flexible composites. Studied the impact response of different preparation processes, initial impact energy, and punch shapes and diameters on materials. The results showed that the flexible composites prepared by various processes exhibit the same impact response curves in the impact resistance process, while the damage morphology and failure modes of the samples are different. Different initial impact energies caused multiple failure modes in the samples. The material showed penetration damage at high energy impacts and permanent depression damage at low energies. For different punch shapes, the impact resistance of materials to hemispherical punches is better than that of cylindrical punches. Numerical simulations were carried out using the finite element software ABAQUS. The custom material subroutine (VUMAT) based on the Hashin damage criterion model was implemented in the finite element program. The experimental and numerical simulation results agree regarding impact response characteristics. This paper analyzes the composite damage shapes, crack extensions caused by low-velocity impact tests and finite element simulation on multi-axial warp-knitted flexible composites. It provides a valuable reference for failure and structural optimization of multi-axial warp-knitted flexible composites for architectural applications.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Due to its low hydrophilicity, direct sublimation inkjet printing on woven polyester fabric surfaces is challenging. This research experimentally studies the efficacy of dielectric barrier discharge (DBD) roll-to-roll plasma treatment with or without water vapor post-exposure as a novel method to modify polyethylene terephthalate (PET) surfaces to enhance hydrophilicity, color performance, and printing quality. The Response Surface Methodology (RSM) was used to design experiments, and the optimum conditions were analyzed through statistical calculations. Their results were examined using Optical Emission Spectroscopy (OES), Atomic Force Microscopy (AFM), field emission scanning electron microscopy (FESEM), Energy Dispersive X-ray (EDX), X-ray Photoelectron Spectroscopy (XPS), and Attenuated Total Reflectance Fourier Transform Infra-Red spectroscopy (ATR-FTIR) tests. Qualitative and quantitative tests for color performance and wicking test used for hydrophilicity assessment confirms the effectiveness of this Green inline pretreatment for industries to enhance direct sublimation inkjet printing quality on PET by a decrease in absorption time from 12051 to 202 s and an increase in the color depth to 12.49%, 25.89 and 18.07% for Cyan, Magenta and Key (black) respectively. One of the stable optimum conditions in which three printed colors: Cyan, Magenta, and Black (Key), show high-quality color performance is at 15 processing rounds, 2 m/min velocity in the absence or presence of water vapor post-exposure. Water vapor post-exposure exhibits a beneficial, economic effect along with plasma treatment. The results show that the chemical modification aspect of this treatment plays a more significant role in printing quality enhancement than its morphological modification.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Traditional silk, known for its strength, flexibility, and comfort, shows promise as a lightweight, comfortable material for stab-resistant armor. This study explores enhancing silk’s knife-stabbing resistance for soft body armor through surface treatments. This study aims to augment the knife-stabbing resistance of silk fabric for soft body armor. Designed a falling tower setup to investigate fabric responses under impact. Exploring the addition of layers with coatings like silicon dioxide deposition, rice ash deposition, and aluminum oxide particles, the investigation revealed significant enhancements. A solitary silk layer exclusively coated with resin exhibited improvements of approximately 37.07%, 29.21%, and 13.47% in stab resistance for rice ash, aluminum oxide, and silicon oxide particles, respectively. The specific knife penetration depth indicated that the coating is more effective in diminishing penetration depth. The research identified that 7 layers of pure silk and 3 layers coated with rice ash satisfy National Institute of Justice Standard–0115.00, S1 as 26 layers of silk fabric, demonstrating a reduction without compromising protective efficacy.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  The production technology of one of the essential structural parts of rubber-textile conveyor belts, the textile carcass, has not changed much since the start of their use. Specific changes occurred only in the material used when various synthetic fibres gradually replaced cotton. However, with the development of additive technologies, the possibility of changing the production technology is coming to the fore, when industrial textiles produced by classic weaving will not be used to make the carcass but a structure built by 3D printing. Confirmation of this change would represent a revolutionary breakthrough in the technology for rubber-textile conveyor belt production. Based on these facts, the possibility of using continuous 3D printing technology was verified to print a structure that would replace the technical fabric used in the conveyor belt carcass. As part of the research, the Selective Laser Sintering (SLS), Fused Deposition Modeling (FDM), and Stereolithography (SLA) technologies were verified. Experimental specimens with the dimensions of 145 x 145 x 185 mm were produced in three different positions: at an angle (45°), horizontally, and vertically. The specimens were made of three types of filament: SLA (Elastic 50A), SLS (TPU 1301), and FDM (Flexfill 92A); for each of the three positions of the specimen, filament consumption and printing time were determined due to the use of support material. Created specimens were then assessed regarding their production possibility and achievement of the desired structure.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  This study investigates the performance degradation and prediction of polyvinylidene fluoride (PVDF) membrane materials under natural aging conditions (2 MPa prestress) and artificially accelerated aging conditions. Initially, the tensile strength, elongation at break, elastic modulus, tear strength, and apparent properties (transmittance, reflectivity, and conjugated double bond absorption area) of the membrane material were measured through uniaxial tensile testing, trapezoidal tear testing, and ultraviolet (UV) testing. These measurement results were then compared and analyzed in relation to tear strength and apparent properties under artificially accelerated aging conditions. The results indicate that UV irradiation and 2 MPa prestress play a crucial role in the degradation of PVDF membrane material properties. Finally, an enhanced Arrhenius equation, accounting for the triple effects of irradiation, oxygen pressure, and temperature, and Schwarzschild’s law, were employed to establish a correlation between natural (2 MPa prestress) and artificially accelerated aging performance of PVDF. The results demonstrate that the enhanced Arrhenius equation provides a more accurate prediction compared to Schwarzschild’s law.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Government policies focus on the textile sector to follow a tendency towards sustainability and circular economy, thus, raising the use of recycled textiles which require further performance improvement to be completely competitive with other textile products while using secondary treatments that are also environmentally friendly. In this study, a 100% recycled polyester weft-knitted fabric, currently used by commercial brands in the apparel and sport textile industry, is calendered and its properties are examined before and after such treatment. This research investigates variations in the physical (appearance and thickness), mechanical (tensile strength and elastic recovery), and physiological (water vapour resistance, spray test, and wettability) characteristics of the samples. The calendering treatment reduces water vapour resistance up to 23%, which is particularly interesting for garments used in sports. Additionally, the contact angle is increased by the calendering process which translates in poorer wettability. Novel findings of this work include that, whereas in the original fabric sweat marks are visible, sweat stains do not appear on the calendered fabric and moisture management improves, while mechanical properties do not undergo significant changes. These results have not been previosly found in the literature, giving a particular interest to a conventional process in this type of recycled fiber that can contribute to the advancement of knowledge in the textile industry and enhance the performance of treated fabrics. All these aspects make the treatment particularly interesting to improve the technical performance of the textile material while using an economic treatment with low effect on the environment.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  In this study, bacterial cellulose was produced through the fermentation of a mixture of black tea, ginger, and sugar, and used to create bio-textile films on sugarcane-based media. Characterization included ribosomal RNA gene sequencing, FTIR spectroscopy, XRD, and SEM was used to examine surface morphology. The bio-textile films showed increasing UV resistance beyond 10 days of cultivation (T.UVA%; 0.13 ± 0.02, T.UVB%; 0.22 ± 0.01, UPF; 629 ± 2.12) and antimicrobial resistance was assessed by quantifying Colony-Forming Units (CFU), resulting in a 100% reduction in growth for both Escherichia coli and Staphylococcus aureus. Subsequently, after 15 days of cultivation, antimicrobial activity was evaluated using the disc agar diffusion method, yielding noteworthy outcomes. E. coli displayed a 25 mm zone of inhibition, S. aureus exhibited a 31 mm zone of inhibition, Candida albicans showed a 35 mm zone of inhibition, and Aspergillus niger presented a 22 mm zone of inhibition.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Nowadays, electrically conductive textile materials are widely used also for sensing applications in addition to being used as antistatic, electromagnetic shielding, for creating smart textiles, etc. The main aim of this paper is to study the effect of tensile deformation applied on knitted fabrics on their electromagnetic shielding ability, electrical resistance, and porosity to gain knowledge for the construction of textile-based wireless strain sensors. For the experiment, silver-coated yarn was chosen to produce knitted fabrics with two different patterns and three levels of stitch densities. The uniaxial and biaxial deformation was applied to samples and at the same time, the change of electromagnetic shielding ability, electric resistance, and porosity of the sample set was evaluated. It can be summarized, that the vertical stretch has the highest positive effect on the electromagnetic shielding ability and the maximum shielding sensitivity is 12 % compared to other deformation types. In general, the electrical resistance decreases during increased stretch due to the increasing number of contacts between electrically conductive yarns, which causes a decrease in the contact resistance and also a decrease in total electrical resistance. The highest positive effect on the porosity of samples represents biaxial deformation. The finding that the overall shielding efficiency is positively influenced by the electrical conductivity of the sample and at the same time negatively influenced by the increasing porosity during tensile deformation was the motivation to construct a simple regression model for the prediction of the electromagnetic shielding ability of the sample during its extension.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  The present research paper explores the potential of electrospun nanofibers in the promising field of skin tissue engineering. Specifically, we propose an advanced preparation and characterization of an electrospun Polyurethane/Calcium Chloride (PU/CaCl2) nanocomposite scaffold, devised to boost the scaffold’s physicochemical and biological properties for skin tissue regeneration. By incorporating CaCl2 into the PU matrix using an electrospinning process, we were able to fabricate a novel nanocomposite scaffold. The morphological examination through Field Emission Scanning Electron Microscope (FESEM) revealed that the fiber diameter of the PU/CaCl2 (563 ± 147 nm) scaffold was notably smaller compared to the control (784 ± 149 nm). The presence of CaCl2 in the PU matrix was corroborated by Fourier-Transform Infrared Spectroscopy (FTIR) and Thermogravimetric Analysis (TGA). Furthermore, the PU/CaCl2 scaffold exhibited superior tensile strength (10.81 MPa) over pristine PU (Tensile −6.16 MPa, Contact angle - 109° ± 1° and Roughness - 854 ± 32 nm) and revealed enhanced wettability (72° ± 2°) and reduced surface roughness (274 ± 104 nm), as verified by Contact angle and Atomic Force Microscopy. The developed scaffold demonstrated improved anticoagulant properties, indicating its potential for successful integration within a biological environment. The improved properties of the PU/CaCl2 nanocomposite scaffold present a significant advancement in electrospun polymer nanofibers, offering a potential breakthrough in skin tissue engineering. However, additional studies are required to thoroughly evaluate the scaffold’s effectiveness in promoting cell adhesion, proliferation, and differentiation. We aim to catalyze significant advancements in the field by revealing the creation of a potent skin scaffold leveraging electrospun nanofibers. Encouraging deeper exploration into this innovative electrospun composite scaffold for skin tissue engineering, the PU/CaCl2 scaffold stands as a promising foundation for pioneering more innovative, efficient, and sustainable solutions in biomedical applications.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Warp-knitted spacer fabrics are a widely considerable material owing to its unique sandwich structure and superior performance, employed across diverse fields such as military, transportation, construction, and personal protection. However, they are inevitably subjected to impacts in practical applications. This work investigated the influence of surface layer structure on the impact resistance property of fabrics by drop weight tests. The damage tolerance of warp-knitted spacer fabrics was also studied through repeated impact experiments. To further improve the impact resistance property of the fabric, a simple sewing method was proposed in this work. Inspired by the spiderweb structure, a spiderweb shape was sewn on the fabric. The results demonstrated that hexagonal mesh as the impact surface provided better impact resistance for the fabric. As the number of impacts increases, the deformation of the fabric gradually intensifies, and the fabric is completely damaged during the fourth impact. The stitch can enhance its impact resistance, and the shape of the stitch had a significant influence on the impact resistance performance.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Research purpose: The low patency rate (less than 50% at a 5-years follow-up) of commercial vascular grafts is strongly associated with compliance mismatch between graft und native artery. To address this deficit, we investigated the influence of the material and structural elasticity on the compliance behavior of small caliber vascular graft gaining for a stress-strain behavior adapted to the native vessel. Material & Methods: By combining different thermoplastic polycarbonate urethanes (TPU) fibers with different elasticity and non-elastic polyvinylidene fluoride (PVDF) fibers in different warp knitted tubular textile structures, we incorporate material and structural elasticity in a vascular graft (I.D. < 6 mm). The evaluation of the tubular fabrics is performed by determining the compliance properties in a mean pressure range between 20 and 120 mmHg by tensile testing. Results: We identified the draw ration of the TPU fiber production, the stitch course density of the fabric and the thread tension of the TPU yarn during the warp knitting process as statistically highly significant effects (p < .005) on the compliance. With an adapted setting of those parameters, we were able to improve the compliance of the textile vascular grafts over the entire physiological pressure range (20–120 mmHg) by 400–630 % compared to current clinical ePTFE (expanded polytetrafluoroethylene) grafts towards native vessels. Conclusion: By combining material and structural elasticity in a warp knitted textile structure, we were able to biomimic the compliance towards physiological properties. Our approach can be seen as blueprint to adapt elasticity properties in other implant applications.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  This study introduces an innovative high-Quality factor (Q-factor) double negative (DNG) metamaterial sensor designed for textile fabric and fabric moisture sensing applications in the dynamic realm of textile innovation. The sensor is specifically designed to detect the dielectric properties and moisture content of different textile fabrics. The high Q-factor of this metamaterial structure ensures heightened sensitivity and accuracy in fabric sensing, facilitating precise detection of even subtle changes in fabric properties. By measuring frequency shifting and analyzing S21 values, the sensor provides crucial information about the fabric’s dielectric characteristics. Sensing experiments conducted on various fabrics, including cotton, denim, corduroy, organza, and polyester unveil distinctive patterns of frequency shifting and Q-factors, establishing a nuanced link between fabric structure and sensor performance. The proposed sensor is capable of detecting fabrics with a very low dielectric constant variation of 0.05. In the experiment, the high-dielectric fabric denim (1.7) exhibited frequency shifting and Q-factor of 6970 and 834.87, respectively. Moreover, it is worth noting that the low-dielectric fabric organza (1.03) exhibits frequency shifting and Q factors of 2190 and 1367.03, respectively. Experimental results affirm the prominent efficacy of the proposed sensor in fabric and fabric moisture sensing. Its high Q-factor empowers the sensor to accurately detect and monitor fabric properties, rendering it highly suitable for critical tasks such as quality control, energy efficiency optimization, and process enhancement within the textile industry. The proposed metamaterial sensor (MMS) can significantly contribute to the development of a smart textile sensing technology and pave the way for innovative applications in the textile industry.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Modifying cotton fabrics to obtain significant new properties is of relevance to creating multifunctional textiles that could address challenges across different sectors. One of the critical challenges associated with textiles is hospital-acquired infections, which could be prevented through the utilization of antimicrobial fabrics. Titanium dioxide (TiO2) nanoparticles (NPs) have been introduced in literature for their photocatalytic antibacterial applications against prevalent microorganisms, such as Escherichia coli and Staphylococcus aureus. A newly developed coating process was utilized that includes chemical modification and nanocoating of cotton fabrics to achieve safe to use products that demonstrate durable and highly effective antibacterial properties. Thorough characterization was conducted to analyze the properties of the utilized materials and investigate the quality of the NPs coating on the cotton fabrics. Bacterial cultures and colony counts were performed using standard microbiological techniques. Bacterial studies revealed that the TiO2 NPs coated textile exhibited a significant antibacterial property with 99.99% bacteria growth reduction for S. aureus and E coli, in comparison to the control cotton fabrics. Coating durability analysis was also conducted by washing the coated fabrics using a standard protocol and repeating the qualitative and antibacterial characterization. The durability study revealed the outstanding performance of the coating technology to withstand at least 40x intensive washing cycles with>98% bacteria growth reduction for S. aureus and E coli. These results demonstrate the effectiveness and commercial suitability of the presented process to produce cotton textiles with outstanding antimicrobial properties that can reduce hospital-obtained infections.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  The diagnosis of neuromuscular diseases is complicated by overlapping symptoms from other conditions. Textile-based surface electromyography (sEMG) of skeletal muscles, offer promising potential in diagnosis, treatment, and rehabilitation of various neuromuscular disorders. However, it is important to consider the impact of load and pressure on EMG signals, as this can significantly affect the signal’s accuracy. This study seeks to investigate the influence of load and pressure on EMG signals and establish a processing framework for these signals in the diagnosis of neuromuscular diseases. The sEMG data were collected from healthy subjects using a textile electrode developed from polyester multi-filament conductive hybrid thread (CleverTex). The textrode was embroidered directly on an elastic bandage (Velcro® strap) placed on volunteer’s muscles while different activities were performed with varying loads and pressure. The collected data were pre-processed using standard techniques of the discrete wavelet transform to remove noise and artifacts. The performance of the proposed denoising algorithm was evaluated using the signal-to-noise ratio (SNR), percentage root mean square difference (PRD), and root mean square error (RMSE). Various signal processing approaches (filters) were considered and the results were compared with the proposed EMG noise reduction algorithms. Based on the experimental results, the fourth level of decomposition for the sym5 wavelets with the Rigrsure threshold method achieved the highest signal-to-noise ratio (SNR) values of 16.69 and 21.91, for soft and hard thresholding functions, respectively. The SNR values of 22.11, 21.54, and 2.78 at three different pressure levels 5 mmHg, 10 mmHg, and 20 mmHg, respectively, indicate the superior performance of wavelet multiresolution filter in de-noising applications.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  An air gap in thermal protective clothing (TPC) plays an important role in determining heat transfer, but it may also increase the amount of stored thermal energy that would discharge to the skin after exposure, especially when the TPC suffers compression. To investigate the effect of air gap and compression on the dual thermal protective performance (TPP), thermal hazardous performance (THP) and overall thermal protective performance (OTPP) of TPC, nine air gap configurations with different sizes and positions and five compression levels were designed in this study. Regression models were established to explore the relationships among air gap size, compression and THP for different air gap positions. The results demonstrate that increasing the air gap size without exceeding 12 mm not only significantly enhances the TPP by impeding heat transfer from the heat source to the fabric system during exposure but also decreases the THP by reducing heat discharge from the fabric system to the sensor even when compression is applied. Although an inner air gap contributes more to increasing the TPP during exposure than an outer air gap, it may also bring about severe stored energy discharge when compression is applied. It suggests that a larger air gap size should be divided into individually separate air gaps within different fabric layers to reduce the heat transfer during exposure as well as lower the stored thermal energy discharge after exposure.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Carbon nanotubes (CNT) sheet is a new type of nonwoven fabric that is being evaluated for different applications. This article presents the first friction-based investigation of the use of CNT sheet as a dust shield. The focus application is for shielding future machinery on the moon from lunar dust. Lunar dust is strongly abrasive; it adheres to all surfaces and causes wear. The absence of an atmosphere and water on the moon, along with its low gravity, and electrostatic adhesion exacerbates the issue of lunar dust, which affects all surfaces, including machinery and human apparel. Friction testing was performed to represent the effect of abrasion occurring on a garment surface while astronauts are working on the moon. The coefficients of static and sliding friction between two CNT sheets, held against each other by a weight, were 0.6 and 0.45, respectively. The presence of lunar regolith simulant reduced the friction coefficients between the two CNT sheets by 33% and 22% for static and sliding friction, respectively. The dust in the sheets was easily cleaned with dry wiping and compressed air, showing no requirement to use water for cleaning in space applications. However, the CNT sheets experienced wear after repeated friction tests. The CNT sheets passed the flammability test standards ASTM D6413/D6413M-15 and NPFA 1971 for applications under extreme heat conditions. Thus, CNT sheet can be considered as a multi-functional material for lunar applications, with shielding protection against dust and electromagnetic waves, and resistance to high temperatures.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Developing green fibrous materials with uniformly distributed metal nanoparticles for highly efficient and recyclable catalysis remains a major challenge. Herein, we developed a simple, effective, and green method to immobilize gold nanoparticles (AuNPs) on polydopamine (PDA)-functionalized silk fibers (SFs) for efficient catalytic reduction of 4-nitrophenol (4-NP). The density and size of AuNPs on the PDA-coated SFs can be tuned by adjusting precursor concentration and synthesis duration, respectively. The AuNPs-PDA-SFs catalysts prepared under optimized conditions could catalyze the reduction of 4-NP, 4-nitroaniline (4-NA), and 4-amino-3-nitrophenol (4-A-3-NP) at the apparent rate constants of 0.087, 0.091, and 0.063 min−1, respectively. After six rounds of flow-through reduction of 4-NP, the AuNPs-PDA-SFs could maintain a 4-NP conversion rate greater than 92%, indicating their superior reusability and consistent catalytic activity. Due to the protein properties of SFs, the AuNPs-PDA-SFs can be degraded by enzymes and alkali solutions. This work may provide new insights for designing advanced fiber-supported recyclable catalysts with high catalytic performance and reusability in wastewater treatment.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Technical fabrics find extensive use as reinforcement in plastic components across various applications. Traditionally, these fabrics are produced using wide weaving machines with a constant fabric width and are then cut to achieve the desired component geometry, leading to significant waste generation. An effective approach to minimizing waste and conserving resources involves utilizing fabrics with outer contours that match the desired component geometry from the outset. Until now, the production of width-variable fabrics during the weaving process has not been achievable using wide weaving machines. Addressing this limitation, this paper introduces a novel reed design specifically developed for wide weaving machines. The paper presents the design concept of the new reed and elucidates the fabric development process associated with its implementation. Furthermore, the resulting fabric properties and physical relationships are demonstrated based on manufactured samples. By enabling the production of width-variable fabrics, this innovative approach aims to contribute to more sustainable manufacturing practices in the field of technical fabrics—reducing waste and optimizing resource utilization.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Silicone elastomers, for example, polydimethylsiloxane (PDMS), have been widely used as cross-linkers for fabrication of flexible strain sensors. They not only lend strong adhesion to adjacent materials, for example, porous fabrics, but also tune their elastic property. Silicone elastomer precursors, which are typical non-Newtonian fluids, can easily penetrate into porous fabrics, driven by the capillary effects of fibers. Unfortunately, such a penetration has negative effects on both adhesion strength and elastic property of PDMS, thus limiting their applications. Here we report a facile method for preparing uniform silicone elastomer films, that is, PDMS, on between porous media via controlling the hydrodynamics of elastomer precursors. Our experiments show that the hydrodynamics of elastomer precursors can be easily controlled by modulating the pre-curing time of PDMS precursors to prevent them from penetration into porous media but keep their high adhesion. Based on this hydrodynamic modulation of PDMS precursors, we firmly adhere conductive silver nanowires (AgNWs) onto knitted fabrics, and further combine composites with common clothing from the point of view of ergonomics, showing the possibility of applying such a modulation to the fabrication of wearable strain sensors. Our findings not only present an understanding of liquid transport in porous media, but also provide a novel method of controlling the hydrodynamics of elastomer precursors in porous media for achieving the effective wearable sensors.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  To expand the application of C/C composites in the field of 5G satellite, this paper explores the influence of different preform structures on the mechanical properties, EMI shielding properties, and thermal conductivity of C/C composites. Three common 3D fabric preform structures with different weaving parameters are designed. The pore evolution process of different samples was analyzed by image recognition processing method and pore partition method. The findings indicate that the 3D Fine weave pierced structure leads to higher graphitization degree. 3D orthogonal woven structure results in a higher compression strength of up to 240 MPa. Furthermore, the molding method of 3D orthogonal woven structure exhibits superior EMI SE and thermal conductivity. The EMI shielding mode of C/C composites is the coexistence of absorption and reflection. And excellent texture and a high fiber volume fraction are beneficial to improve thermal conductivity. In conclusion, 3D orthogonal woven structure is more suitable for producing C/C composites with high strength, superior EMI shielding, and enhanced thermal conductivity compared to 3D Fine weave pierced structure. This study reveals a new control method of high-performance materials for 5G satellites.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Fabric/unsaturated polyester composites have garnered significant attention due to their lightweight properties and superior mechanical characteristics. Despite these advantages, the strength of joints within these composites remains a crucial aspect requiring thorough investigation. This paper presents a study focused on comprehending the factors that influence joint strength in fabric/polymer composites, emphasizing the importance of effective load transfer and robust adhesion within the fabric/polymer matrix. The objective is to minimize stress concentration and enhance load distribution within the joint. The failure mechanism involves a combination of Bearing Failure and shear-out failure, particularly in single-fabric layer composites. The study establishes a linear relationship between composite bending stiffness and the enforcement fabric’s flexural rigidity. A comparison of tensile properties across various joining methods, such as bolts, adhesive bonding, and tongue grooves, reveals that bolt joints exhibit the highest strength and elongation, followed by tongue groove joints. Notably, bolt joints demonstrate elevated toughness, efficiency, and stiffness in samples of two-layer twill fabric when the twill lines are oriented perpendicular to each other. Under these conditions, joint properties are measured at 0.89%, 14804.65 Nm, and 20.46 J, respectively. Increased fabric flexural rigidity yields advantages in terms of load distribution, load transfer efficiency, and dimensional stability. This study deepens the understanding of factors influencing joint strength, contributing valuable insights for the development of optimized joint designs and manufacturing processes. These advancements aim to enhance the performance and reliability of fabric/unsaturated polyester composites in applications requiring high strength and structural integrity.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  In recent years, Fabric-Reinforced Cementitious Mortar (FRCM) has gained widespread application for strengthening reinforced concrete and masonry structures. This research investigated the influence of microfibre parameters on the tensile characteristics of FRCM, focusing on the fibre type, length, and volume fraction. Three distinct types of microfibres were scrutinized: amorphous metallic (AM) fibres, polyvinyl alcohol (PVA) fibres, and nylon fibres. FRCM coupons were designed and fabricated based on the AC434 standard. A tensile experimental program, following RILEM TC232-TDT, revealed the pronounced advantage of employing AM fibres in the pre-cracking stage by significantly improving the crack stress up to 226% and pre-cracking stiffness of FRCM. Conversely, synthetic fibres such as nylon and PVA were beneficial in the post-cracking stage by enhancing cracked stiffness, peak stress, and tensile toughness. Additionally, it was found that using fibres with shorter lengths improved the tensile behavior of FRCM composites in the post-cracking stage due to better random distribution in the cement-based matrix. Finally, an artificial neural network (ANN) model was proposed to predict the tensile parameters of the FRCM composites incorporating microfibres.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Fibre-reinforced composites laminates (FRCLs) are employed in various applications such as in marine, aerospace, automotive, and civil industries due to their lightweight nature, design tailorability, and superior specific mechanical properties. However, they possess extremely low flame resistance mainly due to the inherent flammability of the polymer matrix. Various treatments have been applied to improve the fire resistance of FRCLs. In particular, hybridisation (fibre hybridisation and polymer hybridisation) is an important technique which is becoming very popular to enhance the thermal performance and flame resistance of FRCLs. This article is a comprehensive review of the recent developments that broadly cover the improvements in fire resistance of composite laminates via multi-scale hybridisation; the characteristics of thermal decomposition of FRCLs have been presented to comprehend the need for flame retardancy. Approaches for improving the fire resistance of FRCLs and thermal stability, both in polymer and in fibre systems, are discussed. Enhancing the fire resistance has been significant through additives to the matrix, use of flame-retardant modified fibres at interfacial regions and by way of multi-layered hybrid laminates besides hybridization at fibre, yarn and layer level. Finally, a review is presented on the modelling of fire resistance of composite laminates by considering thermo-mechanical models for the prediction of decomposition and failure of laminates at elevated temperatures.

  Abstract: Journal of Industrial Textiles, Volume 54, Issue , January-December 2024.
  Wearable electronics have attracted have attracted widespread attentions for their promising applications in motion monitoring and human-computer interaction. This paper proposes a flexible wearable joint movement intelligent sensing and recognition system to achieve stable and reliable motion feature extraction and recognition. Flexible graphene hybrid knitted sensor were prepared by transferring graphenes (GNs) agent onto stretchable knitted products via a simple spray-drying approach. The small dynamic movement of human joints for the prepared GNs hybrid sensing gloves, elbow pads and knee pads were converted into electrical signals for sensitive detection. The convolutional neural network fusion long short-term memory (CNN-LSTM) network with self-attention mechanism (SAM) is established for feature training and intelligent dynamic recognition of the measured joint information. The interconnected conductive networks endowed knitted sensor with good flexibility and remarkable electrical conductivity of 37 S/m. The unique conductive networks in the fabric offered excellent linearity and repeatable resistance response variation for better detection of joint motion. The resistant signal was analyzed by feature extraction, data correlation capture and time sequence relationship modeling. Finally, the test results show that the proposed CNN-LSTM with SAM network achieves 97%, 96% and 100% correct recognition rates for gesture signals, elbow and wrist signals and knee signals respectively, which is obviously higher than other recognition algorithms. It has great application prospects in the fields of smart wear, medical detection, and smart elderly care.
