- Emulsification of castor oil using poly (N-vinyl-2-pyrrolidone) for
functional finishing of cotton fabric
Authors: Hesham M Fahmy, Alsaid Ahmed Almetwally
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Castor oil (CAO)/poly (N-vinyl-2-pyrrolidone) (PVP) hybrid was synthesized at different reaction conditions including PVP/CAO weight ratio, temperature, and time. The results indicated that the optimum conditions to synthesis that hybrid is reacting of PVP having a molecular weight of 40,000 Da with CAO at a weight ratio of 30% and temperature of 150°C for 60 min. The synthesized hybrid was characterized via FTIR. Emulsification of such hybrid in water results in a white stable emulsion. The TEM analysis proved that the prepared emulsion of a particle size ranges from 320 to 370 nm. The technical feasibility to apply the produced emulsion for functional finishing of cotton fabric was studied. The results obtained indicated that treating cotton fabric with easy care finishing bath containing the synthesized emulsion results in enhancement in nitrogen content, tensile strength, whiteness index, stiffness, and antibacterial activities along with a decreasing in resiliency, wettability, and surface roughness properties of treated fabric, compared to the control sample. Moreover, incorporation of zinc oxide nano-particles (ZnO-NPs) or dihydroxybenzophenone (DHBP) in the above mentioned finishing bath enhances the functional properties of the finished fabric. Furthermore, dyeing fabric samples with different reactive and direct dyes followed by finishing using the aforementioned finishing bath, in absence of ZnO-NPs and DHBP, gives rise to an enhancement in the color strength of such samples compared to the dyed samples. The fastness to washing and perspiration of only the direct dye dyed/finished sample was improved. Almost all the dyed/finished samples exhibited an improvement in their fastness to the wet rubbing and alkaline perspiration along with a reduction in fastness to light. In addition, the SEM, as well as EDX analysis of treated fabric, was investigated.

- Prediction of fabric drape coefficient using simple measurement method
Authors: Hyohyun Kim, Sungmin Kim, Chang Kyu Park
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
A method for predicting the complex physical properties of fabric using a simple measurement method has been developed. For this, a correlation analysis was performed between the data measured by the traditional measurement method for the physical properties of fabric, KES-FB, and by the simple measurement method, CLO Fabric Kit, which showed a high correlation. Then, a multiple regression analysis was performed between the drape coefficient and the KES-FB complex factors to find a factor that had a major influence on the drape coefficient. From this result, a regression equation for estimating the drape coefficient has been obtained. Euclidean distance calculation was used to find the fabric from the database that is most similar to the measured sample, from which the drape coefficient was predicted. Finally, it was confirmed that there is no statistical difference between the actual drape coefficient and the predicted drape coefficient.

- Punching path optimization method for warp-knitted vamp based on machine
vision and improved ant colony algorithm
Authors: Xinfu Chi, Qiyang Li, Xiaowei Zhang, Hongxia Yan
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Aiming at the current problems of duplicated paths and low work efficiency in machine punching of warp knitted vamp marker points, this paper proposes a punching path planning method of machine vision combined with intelligent algorithms. The method can improve the timeliness of visual recognition of punching location by limiting the search area and similarity function threshold, and improve the ability of global search and adaptive adjustment in punching path planning by combining with the improved ant colony algorithm to calculate a more accurate and optimized path more efficiently. Through the visual recognition test and the simulation test of the improved ant colony algorithm, the results show that the template matching can correctly identify the positioning hole marker points for different styles, rotation directions and lighting conditions, and the recognition accuracy is 0.43 mm and the repeat positioning accuracy is 0.09 mm; meanwhile, the improved ant colony algorithm can effectively avoid the local optimal solution, which can improve the optimal rate of the result by about 38% and the algorithm can reduce the number of iterations of the optimal solution within 60 times, which greatly saves the calculation time of path planning. The method can be used to improve the efficiency of punching in the actual warp knit vamp punching.

- The effect of weft yarn type and elastomer yarn threading on the
properties of elastic warp knitted fabrics. Part II: Thermal comfort
properties
Authors: Olena Kyzymchuk, Arzu Marmaralı, Liudmyla Melnyk, Nida Oğlakcıoğlu, Gözde Ertekin, Berna Cüreklibatır Encan, Svitlana Arabuli, Arsenii Arabuli
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
The aim of this study is to determine the performance properties of elastic warp-knitted fabrics used for medical purposes. The samples were knitted using different weft yarn material and changing the threading order of elastomer yarn. The detailed results of the dimensional and elasticity performance of elastic warp-knitted fabrics had been reported in Part I of this series. In this part, the effects of weft yarn material and the threading order of elastomer yarn on the thermal comfort characteristics were investigated. It has been seen that the type and linear density of the transverse weft yarns and the number of elastomer yarns in the fabric structure affected significantly the thermal comfort and permeability characteristics of the developed elastic warp-knitted fabrics. According to the results, using polyester yarns as weft and reducing the number of elastomer yarns led to an increase in air permeability. Additionally, the thermal conductivity characteristics of the fabrics increased as the number of elastomer yarns in the structure increased. It has been seen that from the results, the water vapour resistance coefficient of the samples is appropriate for the usage of these fabrics in medical products.

- Study of the corporate social responsibility in the leather tanning sector
Authors: Adrià Pons, Josep Rius, Carla Vintró, Sergi Lopez
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Reasons to adopt Corporate Social Responsibility reporting by leather tanning companies must primarily be sought in the specific nature of the industry, where leather is a material from renewable sources, however part of its manufacture process might pose one of the gravest environmental hazards in the world. The tanning industry appears, therefore, as a sector compiling CSR reports expected to confirm its environment-friendly actions. The purpose of this research is to examine and understand CSR roles and diffusion in the small and medium enterprises of the leather tanning industry in Catalonia (Spain), especially in relation with the adoption of other management systems. It identifies the most distinguished CSR practices, procedures and metrics and the profiles of companies more prone to adopt them. We used a qualitative approach to fulfill this aim. Results show that leather companies are familiar with CSR practices, but there is further scope for improvement in terms of formalization of CSR procedures and measurement systems. Results show that the majority of socially responsible practices are related to environmental issues and consequently there is a relation between CSR and the application of environmental management systems. The analysis reveals that the management of CSR activities improves with the diffusion of knowledge on CSR practices.

- Research on intelligent recognition of trouser silhouettes based on label
optimization
Authors: Xuewei Jiang, Ziling Chen, Cheng Chi, Sha Sha, Jun Zhang
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
With the development of online shopping platforms, consumers and designers need to choose from a large number of garments when shopping or designing. Quick identification of clothing products can effectively improve the efficiency of designers’ and consumers’ experience. Therefore, this paper used DeepLabV3+ combined with deep separable convolution to improve the network computation speed. To address the problem of low recognition rate of H-shaped silhouette in semantic segmentation, the fuzzy trouser silhouette samples are further analyzed. The trouser silhouette was redefined according to the characteristics of pants, and the dataset labels were optimized with a trouser silhouette classification method. It was found that the accuracy and efficiency of trouser silhouette recognition were significantly improved. The indicators of recall rate, IoU and PA of H silhouette is improved by 6%, 5%, and 1% respectively. After label optimization, the classification prediction accuracy of silhouette V is 100%, the recall of silhouette V is 97%, and the recall of silhouette O is 96%.

- Consumer perception on sustainable clothing among urban Indians
Authors: R Tryphena, I Arul Aram
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
This study examines the urban consumer in India, the largest category among the stakeholders of sustainable fashion. A survey on consumer perception and consumer behaviour with regard to a green purchase decision of sustainable or eco-friendly clothing was done among 460 participants in two of the south Indian cities of Chennai and Bengaluru. A conceptual framework was adapted for green consumerism from the Theory of Planned Behaviour. The theory was used to understand consumer perceptions and their influence on their purchase behaviour with regard to sustainable clothing. The ‘product attributes’ of sustainable clothing brands were considered as intervening variables and their effects on ‘green purchase decision’ were examined. Probit regression was used to analyse the data. One of the significant findings of the study is that ‘environmental knowledge’, ‘environmental attitude’ and ‘perceived consumer effectiveness’ have a significant effect on urban ‘purchase intention’ of sustainable clothing. Practical implications of the study are discussed.

properties of elastic warp knitted fabrics. Part 1: Structure and
elasticity

Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
The demand for medical textile products is increasing with awareness regarding better healthcare services and efficient medical treatments. Compared to other textiles, elastic warp knitted materials, which have elastomer threads in each wale have been widely used in producing medical and preventive products. Thus, in order to decrease the weight and cost of these products without effect on fabric’s stretchability, in this study, various elastic warp knitted fabrics were produced using different raw materials and elastomer threading arrangements, and their properties were investigated. The fabrics were produced on a crochet knitting machine with five different arrangements of elastomer threading and four different laid-in yarn materials as polyester, cotton, and linen. Then the dimensional properties and elastic behaviors of the samples were determined and evaluated comparatively. Statistical analysis showed that all studied elastic warp knitted fabrics have high provide elasticity at a higher than 95% level. On the other hand, the mass per unit area of the fabric is reduced, with the use of linen yarn as weft yarn, or when the total linear density of the weft yarn and the amount of elastomer threads decrease. Finally, the obtained results revealed the possibility to reduce elastomer consumption to decrease weight for elastic medical products, which were developed, without effect on fabric’s stretchability and elasticity as well as replacing synthetic threads with natural yarns in order to improve product comfort.

- Corresponding measurement-based patternmaking method for leggings using
three-dimensional body scanning technology
Authors: Hye Suk Kim, Hee Eun Choi
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Based on 3D body scanning, this study developed the corresponding measurement-based patternmaking (CMP) method for leggings that could systematically provide an excellent fit and control tightness for different body parts. The CMP method for leggings was qualitatively validated by comparing the fit suitability of the produced leggings prototypes through a wear test. The results suggest that the CMP method is an option to design leggings with outstanding suitability in terms of appearance satisfaction, size satisfaction, compression satisfaction, usefulness in movement, ease of movement, ease in donning and doffing for different body parts. In particular, the graduated application percentage (GAP) provided an advantage in usefulness in movement, while the fixed application percentage (FAP) showed an advantage in ease in donning and doffing. As such, this study suggests selecting the CMP method of the application percentage (AP) depending on the purpose of use. This study demonstrated that the proposed method ensured validity in directly implementing a leggings pattern with 3D body scanning and body measurement alone.

Authors: Zhongxian Hu, Guifang He, Xuming Zhang, Tao Huang, Hongxia Li, Yuhai Zhang, Dan Xie, Xiuzhuang Song, Xin Ning, Fanggang Ning
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Aiming at the problem that the existing rope falling device can only detect the impact force and cannot synchronously detect the impact displacement, this paper introduces a large-range high-precision displacement sensor and constructs a rope impact force-displacement detection device. Taking the nylon kernmantle rope for high-altitude fall protection commonly used in aerial work and rock climbing as the research object, the impact response behavior of the rope when drop mass is dropped once and repeatedly is systematically studied, and the impact force and impact displacement are discussed. Further, the evolution of the elastic modulus of the rope is discussed and this could provide theoretical support for the design of the impact-resistant rope structure and the rope impact protection.

Authors: Yeonghoon Kang, Sungmin Kim
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
In this study, the dynamic changes in human body shape according to movement have been analyzed using three-dimensional scanning system. For this, 12 male subjects were scanned in six postures and the amount of changes in 32 anthropometric measurement items were examined. As for the height items, all items changed in walking pose, and for the length items, the shoulder and chest lengths were affected by arm movement. For circumference items, considerable changes were observed in the chest and waist region according to the movement. A body cross section analysis software has been developed to analyze the change in body shape according to movement in various perspectives. As a result, the chest region was found to be affected by the movement of the arms, the waist region by the movement of the trunk, and hip region was by the movement of the leg.

- Experimental investigations on nonlinear mechanical behaviors of Kevlar
tether
Authors: Ban Wang, Haozheng Li, Juyong Zhang
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
A Kevlar tether usually exhibits strong nonlinearity in engineering applications, bringing new challenges to the modeling of tether dynamics. The nonlinear mechanical behaviors, including creep behavior, nonlinear stiffness, hysteresis effect, and dynamical property of a Kevlar tether, are investigated through a series of experiments. The longitudinal loading experiment setup is established, from which the relationships between tether deformation, tension, and time can be obtained. The creep process of Kevlar tethers is divided into three stages, namely, linear creep stage, deceleration creep stage, and long-term creep stage. This paper studied the longitudinal nonlinear stiffness of a Kevlar tether, whose nonlinearity is fitted by the cubic function model. The hysteresis effect under single loading and unloading is fitted well by the Kawabata stress-strain model, which verifies the correctness and validity of Kawabata model. The nonlinear dynamical model, which includes the elastic force, hysteresis force, and damping force, is established to describe the general dynamical property of the Kevlar tether. The experiment results verify the correctness of the dynamical model form. To simplify the analysis, a simplified model is proposed to describe the dynamical property of the Kevlar tether, and the parameters have a good consistency. The works in this paper contribute to the accurate modeling of flexible tether and lay the foundation for the further research of tether dynamics and control.

- Research on the function of single jersey based on the 3D channel
structure
Authors: Yu Xuliang, Sun Fei, Cong Honglian, Dong Zhijia
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
The main purpose of this experimental study is to determine the thermal properties and the moisture conduction function of a single jersey with a three-dimensional channel structure. As the channel structure of single jersey is gradually applied in the functional sportswear sector, the channel structure has been knitted by single jacquard technology for research purposes. Firstly, the formation principle and the structural unit of knitted fabric with the channel structure were explained. Then, the effects of channel structure with different sizes on thermal insulation, quick-drying, wicking height, and moisture management performance of the fabrics were investigated. Finally, the performance characteristics of the channel structure fabric were analyzed through the channel structure model. The analysis obtains that the channel structure of the sample holds more stagnant air and a large evaporation area. Moreover, as the courses or wales of structural units increase, the thermal insulation rate and the evaporation rate of the fabric improve accordingly. Also, it has a superior effect on the improvement of the wicking effect and the unidirectional transmission of the fabrics. However, when the structural unit exceeds a particular value, the fabric structure begins to deform, which makes its wicking height and unidirectional transmission properties decline. It provides a reference for the design and development of the 3D channel structure of the functional knitted fabric.

- Research on manufacturing of three component composite fiber with complex
cross-section pattern
Authors: Chongchang Yang, Junping Zhang, Fei Li, He Ye, Yingcui Yang, Pei Feng
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
In this work, a preparation method of three-component composite fibers with complex cross-sectional patterns is proposed, and the fibers with complex cross-sectional patterns are fabricated using melt spinning. Initially, inspired by the shape of a fishbone, a spinning pack with three-component melt channels is designed for spinning fibers with a fishbone cross-sectional pattern. Then, the numerical simulation of the melt flow in the channels of the spinning pack is performed using Polyflow software. The spinning pack structure is optimized by analyzing the flow velocity distribution and shear rate distribution of different components within the spinning pack channels. The results show that smaller velocity fluctuations contribute to the clarity of the cross-sectional pattern. Thereafter, the spinning experiments are carried out based on the optimized spinning pack. The effect of the flow ratio between the three components on the cross-sectional pattern is discussed, and the three-component composite fibers with a clear fishbone cross-sectional pattern is obtained. Finally, in order to further study the effectiveness of the complex cross-sectional pattern fiber preparation proposed in this paper, another spinning pack for fibers with an H-shaped cross-sectional pattern is designed according to the aforementioned method, and spinning experiments are carried out. The SEM images of the cross-sections of fibers with fishbone and H-shaped cross-sectional patterns are obtained, verifying the feasibility of the method proposed in this paper. Moreover, the fibers with complex cross-sectional patterns obtained by this method have a certain anti-counterfeiting effect and can also be blended with other yarns to obtain fabrics with anti-counterfeiting effects.

- Sustainable heat insulation composites based on Portland cement reinforced
with date palm fibers
Authors: Nadjoua Bellel, Nadir Bellel
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
In order to ensure thermal comfort and reduce energy consumption, a new composite based on Portland cement and date palm fiber was studied in this work. Our main objective is to study the possibility of integrating and using this new material as a thermal insulation material in the exterior coatings of buildings. Several composites were prepared for different weight concentrations (from 0% to 5%) of date palm fibers. The studied materials were analyzed by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). In addition, the hot wire method was used to measure thermo-physical properties. The results show that the addition of fibers has no effect on the chemical composition of the matrix, as shown by FTIR and XRD analyzes which proves the chemical stability. The results of the TGA analysis indicate that the inclusion of date palm fibers has an effect on the thermal characteristics of the matrix. The SEM analysis shows that there is good adhesion between the Portland cement and the plant fibers used and that the date palm fibers are well incorporated into the matrix, the SEM images also showed that the inclusion of the fibers increases the porosity. In addition, the results showed that the addition of the fibers of date palm a marked decrease in thermal conductivity, which makes the material insulating. Thus, the use of fibers in cement seems to be a promising option that allows it to be applied as a thermal coating material in buildings.

- Recent advances in piezoelectric textile materials: A brief literature
review
Authors: Gabriela Maestri, Ludimilla B Ferreira, Pedro Bachmann, Ana AM Paim, Claudia Merlini, Fernanda Steffens
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Smart textiles (ST) can be defined as materials capable of detecting an external stimulus, responding, and adapting its behavior according to the stimulus obtained. The field of study and development of these materials is extensive, and ST can be seen in areas such as health, transport, security, civil construction, and sports. Piezoelectric textiles are part of the ST category and are characterized due the ability to generate electrical energy from mechanical stimulus, and vice versa. Therefore, the main objective of this review is to present the current research on piezoelectric ST. In addition, the study highlights the process of obtaining materials with piezoelectric properties and the challenges and limitations, seeking to understand the contribution of the development of these materials in the field of wearable electronic devices. Thus, the main challenge in developing piezoelectric textiles is in the ability to supply energy to electronic devices to be applied in various fields such as motion detection, acoustics, impact absorption, among others. Moreover, piezoelectric ST is remarkably promising for the development of wearable electronic textiles (e-textiles) that consequently impact the creation of new functional materials that enable renewable sources to offer a positive contribution in the daily society.

- Effects of inter-yarn friction on responses of woven fabrics with
different weaves to a low-velocity impact
Authors: Canyi Huang, Lina Cui, Yiping Qiu, Chuyang Zhang
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Many researchers have reported that inter-yarn friction has an important effect on the response of the plain-weave fabric to an impact. However, the effects of inter-yarn friction on impact responses of woven fabrics with other weaves have not been studied in detail. In the present work, numerical analysis was utilized to study the effects of inter-yarn friction on responses of woven fabrics with different weaves (the plain weave, 2/2 twill, 2/2 basket, and 3/1 twill) to a low-velocity impact. Both inter-yarn friction and the weaves of the woven fabrics greatly influenced the responses of the fabrics to a low-velocity impact. The higher the inter-yarn friction, the higher the levels of the tensile stresses concentrated near the centers of impact of the woven fabrics, and the earlier the failures of the fabrics. In addition, the greater the inter-yarn friction, the higher the velocities of the transverse stress waves in the woven fabrics, and the more effective the distributions of impact energy from the primary yarns of the fabrics to the secondary yarns of the fabrics. Although it had the lowest velocity of the transverse stress wave, due to its firmly interlaced yarns, the plain-weave fabric had the highest total energy absorption capacity among the woven fabrics with the different weaves. On the other hand, due to its loosely interlaced yarns, the 3/1 twill fabric had the lowest total energy absorption capacity among the woven fabrics.

- Investigation of comfort properties of knitted fabrics made of core-spun
vortex yarns
Authors: Gizem Karakan Günaydın, Erhan Kenan Çeven
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Different yarn spinning methods with different fiber combinations provide an optimization for the consumer requests of durability, functionality, comfort, and price. Vortex yarns and the fabrics produced from these yarns have aroused interest for the last years owing to lower yarn production cost and the satisfying fabric comfort properties. Within this work, core-spun vortex knitted fabrics of three different yarn count (400, 300, and 200 dtex) with six different core yarn type (70 dtex Polyvinyl alcohol, 110/36 dtex/filament polyester yarn, 80/36 dtex/filament polyester yarn, 110/333 dtex/filament micro polyester yarn, 50/96 dtex/filament, 120 dtex staple polyester vortex yarn) and two different sheath sliver types (100% viscose, polyester-viscose blended sliver) were studied. Moisture management transport property (MMT), water vapor permeability, and air permeability properties of those knitted fabrics were evaluated comparatively. Obtained results were statistically evaluated using three-way ANOVA test. It was determined that core yarn type, sheath sliver type, and yarn linear density were generally influential factors on MMT, water vapor permeability, air permeability properties of the core-spun vortex fabrics at significance level of 0.05. Correlation analyses between yarn hairiness and water vapor permeability as well as between yarn hairiness and air permeability were indicated. The conducted work provides an initial phase toward a better understanding of influence of some core-spun vortex yarn parameters on comfort properties of knitted fabrics.

- A sustainable approach for linen dyeing and finishing with natural lac dye
through chitosan bio-mordanting and microwave heating
Authors: Naglaa AA El Sayed, Magda A El-Bendary, Omnia Kh Ahmed
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Sustainability has become a global requirement in all industries. In the textile sector sustainability can be achieved by developing innovative techniques, approaches, and machinery. The current study introduces a sustainable approach for linen dyeing with natural lac dye using microwave heating after the treatment with chitosan as a cationic bio-mordant. The chitosan treatment was carried out by a pad/dry-cure process with citric or acetic acid. Linen samples were characterized by scanning electron microscopy (SEM), and fourier transform infrared spectroscopy (FTIR). The results confirmed the deposition of chitosan on linen fabric with both citric and acetic acid. X-ray diffraction (XRD) was used to determine the change in the crystallinity of linen fabric after chitosan treatment and lac dyeing. The color strength results confirmed the successful application of chitosan as a bio-mordant and the efficiency of microwave heating in shortage the dyeing period in lac dyeing, where the K/S increased from 1.54 to reach 18.86 and 13 with acetic and citric acid, respectively in 7 min. Furthermore, the maximum color strength was achieved at pH 3 of lac dye and the presence of chitosan eliminated the usage of salt in the lac dyeing of linen fabrics. Fastness properties of the lac dyed linen fabrics to wash, light, and perspiration have been discussed. The functional properties (antibacterial activity and UV protection) of linen fabrics were assessed. The antibacterial activity was decreased after the chitosan-treated linen samples were dyed with lac dye. However, the UPF of linen samples was enhanced after lac dyeing.

- Statistical analysis of the effect of processing machine parameters on
acoustical absorptive properties of needle-punched nonwovens
Authors: Magdi El Messiry, Affaf K Al-Oufy, Yasmin Ayman, Samar Abdel Latif
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
The object of this paper is to investigate the acoustic insulation properties of needle-punched nonwovens produced from recycled polyester waste blended with virgin polyester serving as supportive material. The research work also studies the effect of different processing parameters of needle punching nonwoven machines through the investigation of different needle speeds, lattice speeds, and penetration depths. Throughout the research work, several needles punched nonwoven fabrics were produced under different conditions as follows: Three needle speeds were applied: 280, 245, and 227 rpm. Three lattice speeds were applied: 0.72, 1.47, and 2.35 m/min. Three depths of penetration for the needles were applied: 26, 10, and 5 mm. Finally, different blends of waste/virgin polyester fibers were produced and tested: 40/60%, 20/80%, and 100% virgin polyester. The four parameters investigated had a statistically significant effect on the sound transmission losses obtained. It was proved that as the frequency increases, the needle speed gains importance while the needle penetration depth loses importance. The results of testing the different samples indicated that the highest sound transmission loss is attained using non-woven fabrics produced from virgin polyester fibers and prepared at high stitch density.

terry socks for winter wear
Authors: Muhammad Sohaib Anas, Adeel Abbas, Habib Awais, Muhammad Ehtisham Sarwar, Tayyeb Ul Hassan, Huma Abbas
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Compared to other textiles, socks are made at the lowest cost and have the highest consumption rate, making them one of the least-lasting fabric goods in the clothing industry. Socks are available in a wide range of fibers blends, that is, cotton, wool, nylon, acrylic, polyester, olefin, spandex, etc. As an element of footwear, socks act in tandem with the foot and shoe, influencing the temperature and moisture levels of the feet. The comfort of clothing next to the skin in terms of temperature and moisture is gaining more and more attention. Pilling is a serious issue with wool items, and less pilling is required since it negatively impacts the esthetic, comfort, and longevity of the fabric. This research has investigated socks pilling tendency and thermo-physiological comfort properties, that is, air permeability and thermal resistance made by wool/polypropylene blend yarn. Three different combinations of wool/polypropylene yarns on the main and platting side of the socks were used at two different tightness levels. Polyurethane finish has been applied to check the socks’ behavior after the finish application. Statistical analysis showed that finished samples knitted with wool/polypropylene as a main yarn offer the best results against the pilling test while sample code ANL, an unfinished sample, offers the best results regarding air permeability, thermal resistance, and overall moisture management capacity.

Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Concrete canvas reinforced with spacer fabric has increasingly gained popularity due to its lightweight, great flexibility, high strength and low contamination compared to ordinary concrete. In order to fully explore the structure and performance of this novel composite, this review illustrates how to design high-performance concrete canvas and presents a summary of recent application status of it. Firstly, the structure and properties of knitted and woven spacer fabric and concrete material that comprise concrete canvas is introduced. Secondly, internal and external mechanisms affecting the properties of concrete canvas have been described. To illustrate how to evaluate and test the mechanical behavior of concrete canvas, typical mechanical experiments such as tensile and flexural experiment and failure mechanisms are explained. In terms of the characteristics of concrete canvas, the present article reviews current applications of it in disaster relief tent, slope protection, ditch lining and furniture design areas. Nevertheless, its practical applications are still in the preliminary stage, it is of great necessity to expand its application from the point of view of replacing traditional materials, changing structural design, external reinforcement and perfecting performance evaluation system.

- Combined bimodal and dense-sparse structures to optimize the performance
of fibrous media for submicron particle capture
Authors: Minghao Chu, Yongfa Diao, Li’an Zhang, Jie Jiang, Tianwei Mu
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Fibrous media are widely used in particle filtration. However, few studies have investigated the performance of fibrous media with bimodal and dense-sparse structures. In this study, computational fluid dynamics technology was adopted to simulate the filtration performance of fibrous media. A two-dimensional random multifiber distribution model was proposed based on VC++ and ICEM. Reliability was verified by comparing the model with the empirical formula. The filtration efficiencies and quality factors of submicron particle capture within different fiber arrangements, inlet velocities, and particle diameters were determined. Finally, the mechanism for improving the filtration efficiency of multi-fiber for submicron particles was analyzed. The results showed that, as the particle diameter and inlet velocity increased, the filtration efficiency and quality factor of the different fibrous media decreased, and tended to be similar. The fibrous media combined with bimodal and dense-sparse structures had the highest quality factor owing to the placement of the bimodal structure on the windward side and ratio of coarse to fine fibers.

- The study of correlations among the process condition, structure and
property for poly(l-lactide) fibers
Authors: Huixian Zhang, Hongwei Bai, Nan Wang, Qin Zhang, Qiang Fu
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
This article focus on derive the process-structure-property relationship of Poly(l-lactide) (PLLA) fibers prepared by two-step melt spinning process. The spinning temperature, spinning rate, drawing temperature as well as draw ratio were studied to analyze the influence of process variables on the structure and properties of PLLA fibers. It suggests that the crystallinity, lamellar orientation structure and mechanical properties of fibers are dependent on the spinning conditions, including melt-spinning and hot-drawing process. An approximate linear correlation resulted between the orientation degree and tensile strength of PLLA fibers, which means that the oriented structure plays a dominant role to enhance PLLA fibers. PLLA fibers with high performance of 499 MPa and 5.30 GPa in tensile strength and Young’s modulus separately have been realized by the selected spinning parameters. The results provide a theoretical direction for enhancing PLLA fibers by adjusting the structure characteristic via modifying the spinning parameters.

- Fabrication of ecofriendly jute fiber reinforced flexible planar composite
as a potential alternative of leather
Authors: Md Abdus Shahid, Md Solaiman Miah, Md Abdur Razzaq
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Natural fiber reinforced composites are a lightweight, affordable, and environmentally friendly replacement for many problematic applications. These natural fibers could be constructed into flexible planar materials with the aid of composite phenomena that can be used for a variety of applications where flexibility is important like as artificial leather. In this work, nonwoven matt made from spinning wastes of jute fiber was used to reinforce the biodegradable polyvinyl alcohol (PVA) matrix. The percentage of fibers within the PVA matrix was adjusted to develop the flexible planar composites. The nonwoven matt was immerged into the PVA solution casting mold with the aid of the solution evaporation approach. The flexible planar composite was then obtained through heat-induced pressing. Tensile strength, tearing strength, bending modulus, flexing endurance, abrasion resistance, and moisture management profiles of the developed flexible planar composite were assessed. Additionally, studies were performed for Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric (TGA) analysis. The tensile strength has been found 7.78 N/mm2 with 9.84% elongation for a 1.2 mm thick flexible composite. The flexing endurance has been supported by no visible crack formation against 50,000 flexing cycles. The moisture management profile has been ensured by the hydrophobic surface of the composite. Developed flexible planar composite has been shown to have consistent mechanical performance for use as artificial leather, which could be appealing for the fabrication of leather-alternative bags, belts, and wallets.

- In vitro experimental study on effect of fiber denier, yarn doubling, and
specialty treatments on physical and thermal behaviors of knitted sports
socks
Authors: Adeel Abbas, Muhammad Sohaib Anas, Zeeshan Azam
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Knitted sports socks remain in continuous scuff with wearers’ feet and shoes during activities. Such continuous physical contact governs severe pills on socks surface, which is unpleasant for both the wearer and the working life of socks. Hence it becomes necessary to take measures for controlling fabric deterioration, that is, anti-pilling treatments. Though pilling performance is enhanced; however, thermal comfort characteristics are compromised through the treatments. Simultaneous acquirement of both pilling and thermal characteristics is an area of interest. Fiber denier and yarn doubling techniques are among the influential factors in the solution to the problem. Specimens have been developed using four different fiber deniers, two yarn doubling conditions, and two specialty wet treatments under a full factorial experimental design. Results showed a significant variation in pilling behaviors and thermal characteristics before and after treatments in the statistical analysis, predicting the possible stages, that is, a combination of experimental factors for desired characteristics attainment.

- Identification of cashmere and wool based on LBP and GLCM texture feature
selection
Authors: Yaolin Zhu, Lu Zhao, Xin Chen, Yunhong Li, Jinmei Wang
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
There are invalid and redundant features in the texture feature extraction method of cashmere and wool fibers, which leads to the low recognition accuracy. In this paper, a novel texture feature selection method based on local binary pattern, the gray level co-occurrence matrix algorithm and chi-square test was proposed to sufficiently extract the effective features of these two fibers. Firstly, the collected images of cashmere and wool fibers are processed to obtain the clear texture images with background removed by pre-processing algorithm and local binary pattern. Then, the texture features are calculated by the gray level co-occurrence matrix, and the optimal 5-dimensional features are extracted by chi-square test to represent the texture information of cashmere and wool. Finally, the two fibers are automatically classified and recognized based on the support vector machine. The experimental results show that the proposed method obtained a high recognition accuracy with the percent of 94.39. It verifies that the method based on texture feature selection is effective to identify cashmere and wool fibers.

- Evaluation model of fabric transient cooling sensation based on multiple
stepwise regression analysis
Authors: Xuemei Li, Shanghui Wang, Yanqing Li, Xiaoke Jin, Leilei Ma, Wei Tian, Chengyan Zhu
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
In this paper, according to the one-dimensional heat transfer mechanism between fabric and human body, it is found that different thermal properties affect different heat transfer stages of fabric. Therefore, we used the maximum heat flux qmax as the index to characterize the transient contact cool feeling of fabrics, and measured the thermal properties, various specifications and surface morphology of 40 kinds of summer fabrics. Firstly, we discussed the influence of the above properties on the transient cool feeling. Secondly, according to multivariate stepwise regression, the significant representative variables are selected, and the prediction model of transient coolness and fabric properties is established. Furthermore, the model was verified to explore the subjective and objective consistency. The results show that, in the transient heat transfer stage, the influencing factors that are significantly related to the cool feeling of fabric include fabric thickness, grammage, volumetric heat capacity, thermal conductivity, warp and weft density, and roughness. The main component representative variables of the cooling sensation regression equation are volumetric heat capacity and thickness, and other variables can be explained by these two variables. Changing them is the key to enhance the cooling sensation. The predicted value of coolness is in good agreement with the subjective evaluation of cooling sensation, which has a certain guiding effect on the actual human cool feeling. The purpose of this study is to find out the main factors that affect the cool feeling, and then apply the established cool feeling model to the development of fabrics in summer, so as to meet the thermal comfort requirements of human body’s fabrics.

- Effect of using alternate elastic and non-elastic yarns in warp on
shrinkage and stretch behavior of bi-stretch woven fabrics
Authors: Lili Jiang, Adeel Zulifqar, Abdul Moqeet Hai, Faiza Anwar, Hong Hu, Fengwei Liu, Haizhen Chen
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Stretch woven fabrics are known for their elastic and recovery properties. To date, they found many interesting applications from simple jeans to complex fabric structures with functional properties for example bi-stretch auxetic woven fabrics, compressions garments and stretchable textile carriers for healthcare applications. Many studies have been carried out on the physical, mechanical and comfort properties of stretchable knitted and woven fabrics. However, to identify combination of yarns with different stretch properties and other design parameters required to meet multiple objectives in the production and usage of bi-stretch woven fabrics is an area that has been taken up by fabric scientists recently. This study compared the effect of using elastic yarns and alternate elastic and non-elastic yarns in warp on the properties of bi-stretch woven fabrics while using elastic yarns in weft direction. It was found that shrinkage of the fabrics made of elastic yarns was higher along the warp direction as compared to that in weft direction due to shrinkage balancing effect; however, in case of fabrics made of alternate elastic and non-elastic yarns in warp the shrinkage behavior was exact opposite. The comparison of shrinkage for different weave patterns revealed that satin had the highest shrinkage followed by twill and plain, due to least number of interlacements in satin among these three patterns.

- Thermal properties, microstructure analysis, and environmental benefits of
basalt fiber reinforced concrete
Authors: Ansam Qsymah, Mohamed Moafak Arbili, Jawad Ahmad, Saleh M Alogla, Khaled A. Alawi Al-Sodani, Ahmad Hakamy, Yasin Onuralp Özkılıç
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Numerous scientists have studied basalt fiber (BF) reinforced concrete and found encouraging results. However, information is scattered, and compressive assessment is yet necessary to collect the data from prior research on BF, present research advancement, and future research guidelines of BF reinforced concrete. Furthermore, mostly research focus to review on strength and durability aspects of BF reinforced concrete while no researched focus on thermal properties, microstructure analysis and environmental benefits of BF reinforced concrete. Therefore, the primary focuses of this paper are BF treatment, BF reinforced concrete performance at high temperatures, microstructure analysis, environmental advantages, and application in civil engineering. Results show that BF-reinforced concrete performs much better than traditional concrete at high temperatures. Additionally, the use of BF enhanced the heat conductivity of concrete. BF addition to concrete seems to have reduced interfacial transition zone (ITZ) fractures, according to a microstructure study. When opposed to traditional steel fibers, BFs may be thought as reinforcements that are less harmful to the environment. The study also highlights the significance of BFs in the building industry. The assessment also identified research gap research for further studies.
