- Construction of grid color mixture model of seven primary-color and
modified Stearns-Noechel color matching algorithm for color prediction of
full-color-gamut rotor melange yarn
Authors: Wenshuo Zhu, Yuan Xue, Yourong Chen, Yaojun Wang, Huanqiang Shi
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
In this paper, the full-color-gamut grid color mixture model containing 601 grid points is constructed by ternary double coupling blending of seven primary-color fibers, and the spinning method of full-color-gamut melange yarn is given by combining with three-channel NC rotor spinning technology. A modified S-N color prediction model was constructed by selecting 55 uniformly distributed grid points for yarn and fabric production from the full-color-gamut grid color mixture model as samples for solving the reflectance conversion coefficients. On this basis, the method of predicting the color value of a melange yarn based on its primary-color fiber composition and blending ratio and predicting the primary-color fiber composition and blending ratio based on the color value of a melange yarn using the parameters of the nearest sample grid point is proposed, and six samples with different blending ratios in six color mixing regions of the full-color-gamut grid color mixture model are designed for validation. The results showed that the average color difference between the predicted color and the actual color of the melange yarn is 1.15, the predicted primary-color fiber composition of the melange yarn is consistent with the actual composition, and the average error between the predicted blending ratio and the actual blending ratio is 3.95%. The method proposed in this paper can effectively predict the color value and blending ratio of melange yarn.

- A methodological framework for the integration of 3D virtual prototyping
into the design development of laser-cut garments
Authors: Evridiki Papachristou, Despoina Kalaitzi, Vasileios Pissas
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
3D virtual prototyping for garment development, although not much exploited and appreciated by the clothing industry in the early days of its appearance two decades ago, has now been explored (research-wise) extensively especially in the pandemic period and its impact on the whole supply chain of garments and fashion products. This virtual prototype which allows the company to visualize the status and condition of a clothing product that may be thousands of kilometers away, providing insights into how products can be better designed, manufactured, operated and serviced before companies invest in physical prototypes and assets, is often called digital twin. At the same time, laser-cut as a creative design technique on clothing materials have emerged in recent times, as fashion moguls are seeing the benefits that the technology presents. Laser cut technology with its benefits of accuracy, speed, precision, applicability in various materials, flexibility in geometry, interoperability with other systems like CAD/CAM and CIM, sustainability in resources and source of inspiration for several upcoming designers, provides an excellent approach for creating bridges between the past, the present and the future in history of fashion design. The aim of this paper was to provide a decision-making framework for the selection of an effective digital twinning process with the use of two different 3D virtual prototyping tools. For this purpose, a methodological framework is proposed which guides the creator according to the final use of the digital garment twin: evaluation of actual fit and actual representation of the produced physical, or as a shared digital asset for an exclusive digital environment.

- Sustainable waste cotton and pigeon pea stalk fibers composite materials
for acoustics and thermal properties
Authors: Veeraprabahar Jawahar, Mohankumar Gabriel, Sakthivel Santhanam, Senthil Kumar Selvaraj
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
This study focuses on the development and characterization of pigeon pea stalk/cotton fibers mixed with a blend ratio of 50/50, 70/30, 30/70, 60/40, 100/0 waste cotton and 0/100 waste pea stalk composites are equipped with a compression molding system. The entire composite samples are tested for acoustics, thermal and physical parameters as per the American Society for Testing and Materials standard (ASTM). The sound absorption coefficients (SAC) were measured according to ASTME1050 by an impedance tube method, and the SAC over six frequencies 125, 250, 500, 1000, 2000, and 4000 Hz were calculated. The result revealed that the composite samples that are prepared from cotton/pigeon pea waste have confirmed more than 80% of the SAC and the waste composites provided the best insulation, sound absorption, moisture absorption, and fiber properties. The effect exposed that composites materials arranged from cotton/pea stalk waste fiber have established further than 75% by the sound immersion measure and the waste 28% composites handed the fashionable Appropriation, sound immersion, humidity immersion, and fiber materials. The waste cotton/pigeon pea stalk composite samples have satisfactory moisture resistance at high humidity situations without disturbing the insulation properties.

- Review on characteristics of concrete reinforced with nylon fiber
Authors: Hisham Jahangir Qureshi, Jawad Ahmad, Amer Aljabr, Natividad Garcia-Troncoso
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
In tension, concrete is often weaker than in compression. To increased the tensile strength of concrete, fibers are added. Nylon fibers (NF) have shown promising results in previous research and tests since their presence has shown significant increases in concrete performance. The purpose of this research is to gather data from previous studies on NF-reinforced concrete (FRC). The key components of this review include concrete flowability, compressive strength, tensile strength, impact strength, rehabilitation, performance during irradiation, and fire resistance. In addition, the article examines the fracture behavior and failure patterns of nylon FRC. The results show that NF enhanced concrete performance, notably tensile capacity, owing to bridging mechanisms, but lowered concrete flow properties. However, the some researcher demonstrates that NF does not improved the compressive capacity significantly. Therefore, the study proposes more research to increase the compressive capacity of concrete by applying alternative treatments to NF or by employing secondary cementitious materials.

- Research of different needle length on properties of PVDF nanofiber
membrane based on long-needle electrospinning technology
Authors: Lei Zhao, Ting Zhu, Li Wei, Jumei Zhao, Jihuan He, Shixiong Yi, Jun Wang, Tianchi Zhou, Lu Cai, Chenghui Zheng
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
In this paper, we combine electrospinning with laminar flow theory to verify the influence of the spinning needle length on the internal structure of PVDF (polyvinylidene fluoride) nanofibers. The long spinning needle is referred as a reference like long ducts in the body of spiders. We also discussed the effect of different needle length on the micro-morphology, mechanical properties, electrical properties, porosity, and hydrophobic properties of PVDF nanofiber membranes. The results showed that when the needle length increased, more PVDF macromolecular chains will have sufficient time to be straightened and aligned, resulting in an increasingly ordered internal structure of the prepared PVDF nanofibers. The different length of the long needle has a certain influence on the morphology, mechanical properties, electrical properties, porosity, and hydrophobic properties of PVDF nanofiber membrane obtained by electrospinning. The more ordered the internal structure of nanofibers, the worse the membrane’s mechanical properties, but the lower its electrical resistivity.

- Effects of step-by-step line balancing in apparel assembly line
Authors: Minsuk Kim, Sungmin Kim
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
The mixed work assignment technique was applied to the modular production concept to solve the apparel assembly line balancing problem. Specifically, an algorithm was implemented to generate workstations by first classifying tasks into modules through an analysis of the manufacturing process and assigning grouped tasks in the single task–multiple workers and multiple tasks–single worker assignment methods. Then, worker assignment was sequentially performed considering the skill level of the worker. A simulation of producing 100 men’s shirts was performed. Owing to line balancing, the total production time was considerably lower than that reported in previous studies. The enhanced performance was attributable to the fact that unlike previous studies that limited the apparel assembly line balancing problem to worker assignment, line balancing was performed through both task and worker assignment in this study. The results demonstrated that task assignment must be considered in the design stage in the apparel assembly line balancing problem.

- A perceptual image prediction model of professional dress style based on
PSO-BP neural network
Authors: Daoling Chen, Pengpeng Cheng
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
In order to understand consumers’ cognition of clothing style and design clothing products more in line with people’s emotional needs, a garment style perceptual image prediction model based on PSO-BP neural network was constructed by taking professional dress as an example. Firstly, the professional dress samples were screened and the style design elements were deconstructed and coded. The Kansei engineering theory and factor analysis method were used to determine the representative adjectives, so as to reduce the cognitive dimension of the target users for the style characteristics and perceptual image of the dress. Then, using the sample style design element code as the input layer and the user’s perceptual image evaluation score as the output layer, the PSO-BP neural network’s perceptual image prediction model for professional dress styles is constructed. Finally, the sample data were input into the PSO-BP model, BP neural network and GA-BP model for simulation and calculation, and the error analysis of the results proved that the PSO-BP prediction model is effective and advanced. Designers can use this model to quickly transform customers’ perceptual needs with dress style design elements, so as to improve the scientificity of design decision-making and better meet customer needs.

- Mechanism and application of halogenation–dehalogenation in the
development of pitch-based carbon fiber: A review
Authors: Jinchang Liu, Qin Liu, Xiaoya An, Tong Wang, Dingcheng Liang, Qiang Xie
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Pitch-based carbon fiber, as one of the important engineering materials, has been widely used in aerospace, defense, sports, and other fields. In the long production process of pitch-based carbon fiber, the property of pitch precursor is significant for the mechanical performance of obtained carbon fiber. Thus, it is crucial to improve the property of pitch precursor by efficient means. Halogenation–dehalogenation is a newly developed method for the controllable synthesis of a pitch precursor from the molecular dimension, including fluorination–defluorination, chlorination–dechlorination, and bromination–debromination. This work reviewed the mechanism and application, as well as the advantages and disadvantages of each halogenation–dehalogenation method.

- Constitutive model and experimental study of molded pulp material
Authors: Zhihang Li, Junjie Tang, Kuanmin Mao, Zhou Zhu
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Molded pulp products can improve the utilization of recycled paper by achieving close to zero waste emission and a 100% recycling rate, while satisfying the national goals for recycled packaging materials of various countries. Molded pulp products are often designed using finite-element simulations to optimize their performance, which requires the input of accurate material properties. However, studies on the constitutive model, an essential factor related to material properties, are still rare. This study investigated the mechanical behavior of the molded pulp material to simplify the parameters and improve the accuracy of the constitutive model. The fiber distribution and connection within the molded pulp material were investigated; treating the pores of the molded pulp as a virtual material enhances the meso-mechanical model and gives a transversely isotropic constitutive model. The elastic modulus in the thickness direction was calculated as 1.5997 MPa, and the experimentally measured value is 1.5368 MPa. The error of proposed model is 4.1%, but significantly smaller than treating molded pulp as an isotropic material, the error of which is ~80 times larger of experimental result.

- Influence of washability treatment on the electromagnetic interference
shielding material’s comfort properties
Authors: Dan Wang, Shi Hu, Dana Kremenakova, Jiri Militky
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
This paper investigated the washability and comfort properties of a kind of electromagnetic interference shielding material (Meftex10) with and without the parylene C coating. Parylene C can form a uniform protective film on the fabric and improve different properties of the fabric. In this paper, it will be used to improve the washability of electromagnetic interference shielding material. Through a large number of experiments, it can be determined that the parylene C coated samples have a significant improvement in washability compared to the uncoated samples. When the sample’s parylene C coating content arrives at 33.4 g/m², its electromagnetic shielding effectiveness still remains around 65% after 10 times washing cycles. Conversely, as the content of the parylene C coating increases, the air permeability of the samples as well as the water vapor permeability will decrease. The reason is that the parylene C coating closes some of the pores, which affects air and water vapor transport through the material. In addition to this, it can be concluded that the thermal conductivities of samples increase with increasing parylene C coating contents. The above phenomenon is caused by the following two aspects: The parylene C coating material will reduce the spaces between the fibers and yarns by partially filling the pores, leading to less still air inside and the fabric has a greater capacity for heat transfer; Parylene C has a higher thermal conductivity than the electromagnetic interference shielding material (Meftex10).

- Experimental study of structural characteristics, dimensional change in
washing, non-creasing properties and air permeability of Swiss double
piqué flax knit fabrics
Authors: Nadiia P Bukhonka
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
The structural characteristics, dimensional change after four washing cycles, non-creasing properties and air permeability of Swiss double piqué knitted fabrics from cotton/flax (70% cotton, 30% flax), PAN/flax (70% PAN, 30% flax) and 100% flax yarns have been investigated. These knitted fabric samples of varying densities were produced on a 10 -gauge circular knitting machine. The results of investigation showed that the structural characteristics, dimensional change in washing, non-creasing properties and air permeability are highly dependent on the type of yarn used. Besides the type of yarn, the structural characteristics, such as the number of wales W and courses C per centimeter, fabric stitch density S, weight Ws, and fabric tightness K, are also influenced by the average loop length la. The weight Ws and thickness t of knitted fabrics are determined by the diameter of the yarn used. Usually, primary dimensional alterations of knitted fabrics of all yarn types occur after the first and second washing cycles. The non-creasing properties of the examined knitted fabrics are mainly affected by the type of yarn, rather than the average loop length la. Lastly, the air permeability AP of knitted fabrics is affected by the type of yarn, the average loop length la, and fabric density S.

- Biomimetic electrospinning for fabrication of poly(lactic acid)/graphite
oxide/poly(dopamine) nanofiber membrane
Authors: Ting Zhu, Lei Zhao, Manyu Qian, Danni Yu, Jihuan He, Weiqing Jiang, Jun Wang, Shuqiang Wang
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
As a new preparation process of nanofibers, electrospinning technology developed by bionic spider spinning can further improve the molecular structure and mechanical properties of nanofibers, and obtain nanofibers and base membrane products with better mechanical properties. The spider spinning needs minimal energy consumption though it has a very long liquid transport tube. Because spider silk has high mechanical properties and wide industrial applications, so a kind of new biomimetic electrospinning technology which harnessed a very long spiral-needle was proposed. Then poly(lactic acid)PLA/graphite oxide(GO)/dopamine (DA) nanofiber membrane was fabricated by the new biomimetic electrospinning technology. The results showed that compared with the pure PLA nanofiber membranes, the average pore size of PLA/GO porous nanofiber membranes decreased, the total number of pores increased, and the fracture strength and elongation at break increased. At the same time, the spun nanofibers were also more uniform. The pore size distribution of nanofiber was more dense after adding DA, and the fracture strength and elongation at break of nanofiber increased, while the nanofiber was also more even. After adding DA, the fracture strength was greatly increased and the elongation at break was similar to that of pure PLA nanofiber. The nanofiber membrane was obtained after oxidative polymerization of DA into poly(dopamine) (PDA), a layer of nanofiber membrane was attached to the surface of nanofiber. The performance of PLA/GO/PDA nanofiber membranes prepared based on PLA/GO/DA nanofiber membranes was superior to that of PLA/GO/PDA nanofiber membranes prepared based on PLA/GO nanofiber membranes, and its adsorption rate after 24 h was as high as 98.81%.

- Preparation and properties of PAN nanofiber membrane based on spiral
spinning technology
Authors: Lei Zhao, Ting Zhu, Li Wei, Jumei Zhao, Qianwen Wang, Jun Wang
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
The PAN spinning solution was chosen as the spiral spinning research object. Laminar flow theory was used to straighten and align macromolecules, and spiral spinning needles were used to control the spiral twisting of straightened PAN macromolecules. The internal spiral arrangement of PAN nanofibers became more compact as the helix number of spinning needles increased. The TEM (transmission electron microscope) was used to photograph the motion trajectory of TiO2 (titanium dioxide) nanoparticles in nanofibers, which directly confirmed the feasibility of the spiral spinning principle. SEM (Scanning Electronic Microscopy) observations revealed that the appearance of the PAN nanofiber membranes changed to some extent under spiral physical technology. The analysis of the tensile and bursting properties of PAN nanofiber membranes demonstrated that the structure of the nanofibers changed significantly after spiral spinning. The pore structure, electrical resistance, and antibacterial properties of PAN nanofiber membrane all reached optimal values at the optimal helix number of spinning needle.

- Investigation of the thermal comfort of the sportswear by standing thermal
manikin and thermal imaging techniques
Authors: Esra Taştan Özkan, Binnaz Kaplangiray, Ufuk Şekir, Şenay Şahin
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Garments should not overload the body during activity and should be chosen in accordance with the ambient conditions. Especially in active sports, sportswear should make a person feel comfortable and increase performance by easily removing excess heat and moisture from the body without interrupting physical activity. In this study, five T-shirts with the same size and weight characteristics, but in different yarn types were produced and analysed. The thermal and water vapour resistance properties of these garments were measured using a thermal manikin system. In addition, thermal camera images were taken at 10-minute intervals during the 50-minute wear trial programme, and skin temperatures were measured from the upper front body and the upper back body with two sensors. The results showed that POS and PM-coded garments made of polyester with low clothing insulation (clo) values were statistically different from CS and CPS coded cotton-containing garments in terms of front and back surface thermal camera images. It was observed that cotton-containing garments were more uncomfortable than polyester and Tencel owing to their higher thermal resistance, garment surface temperature, and skin temperature values. The Tencel garment was measured similarly to the CS and CPS coded garments at the beginning of the activity and measured similarly to the POS and PM coded garments at the end of the activity on both surfaces.

- Develop an optimal daily washing care for technical jacket by balancing
washing efficiency and functional degradation
Authors: Yuhui Wei, Haiyan Zhang, Zhaowei Su, Siqi Tao, Xuejiao Cao, Zihao Wan, Wei Pan
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
In order to reduce the functional degradation caused by improper daily washing-care and prolong the service life of technical jacket, the relationship between the daily washing conditions and functional degradation in the wearing performance of technical jacket (waterproof, windproof, warmth retention) was quantitatively investigated with the help of hydrostatic pressure, surface contact angle, air permeability, warmth retention, and scanning electron microscopy (SEM) of technical jacket after different daily washing conditions. Results showed that no matter what kind of washing modes, washing parameters, type and dosage of detergent, the wearing performance of technical jacket after washing were subjected to decrease compared with pre-washing. Additionally, it was also found that the effects of washing modes, type of detergents and washing parameters on the wearing performance of the technical jacket were significant, instead of the dosage of detergents. This indicates it was possible ways to minimize functional degradation by setting optimal washing conditions (washing parameters, washing mode, types and dosage of detergent). Balancing considerations of functional degradation and washing efficiency, the washing combination of mechanical agitation + micro-nano bubbles), type of detergent (neutral liquid detergent), dosage of detergent (3 g/L), water temperature (20°C), main washing bath ratio (1:10), main washing speed (15 rpm), main washing time (20 min), rinsing speed (30 rpm), rinsing cycles (2), belonged to the optimal washing combination in this study of washing condition. The results were of practical significance to guide manufacturers of washing machine to develop optimal daily washing produce for outdoor clothing, especially technical jacket.

- Role of knitted techniques in recent developments of biomedical
applications: A review
Authors: Usman Ahmed, Tanveer Hussain, Sharjeel Abid
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
All the surgical bandages, extracorporeal devices, and prosthetic implants that we use today are the product of textiles. Because they conform well to the body and feel good against the skin. Woven, non-woven, and knitted are only textile fabric construction methods. Among all, the knitted structures are more breathable and simpler to produce. In the previous two decades, knitting technology has advanced, now it is simple to create customized flexible and cost-effective biomedical devices. Knitted structures are increasingly used in implantable textiles like hernia and heart patches etc. due to their comfort, optimal strength, and ability to ravel from the last loop. The porous structure of knitted fabrics is particularly well suited for the transport of drugs. Since the knitted pattern, yarn effect, and dimensional parameters of fabric are all displayed in the 3D simulation software like Apex-lll and M-1, there is no longer any need to use actual fabric for quality control purposes, which greatly aids in reducing fabric waste. This article offers recent research on knitted fabrics including their advantages, disadvantages and future solutions that could be achieved by using advanced knitting manufacturing technologies. In addition, it calls attention to the significance of knitted structure in biomedical applications which may motivate further research into materials of this kind in the future.

- Multiple response optimization of sizing machine settings and sized yarn
tensile properties using advanced method of experimental design
Authors: Andualem Genene Abay, Million Ayele
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
On a loom, the warp yarns experience exceptionally high mechanical stresses and strains, as well as significant abrasion from friction. As a result, significant yarn breakages cause loom stoppages and, hence, production and quality interruptions. To mitigate this problem, the warp yarns should be treated with a thin, strong film of an appropriate adhesive. The aim of this study is therefore, to investigate the effect of sizing machine parameters on tensile properties of the yarn and to optimize the sized yarn tensile properties. Design expert 11 software with Box-Behnken design has been employed to design the research, analyze the results of experiments, and optimize the responses. In this research, three factors, each at three levels (wet zone yarn tension (A) (340, 380, and 420 N), squeezing roller pressure (B) (13, 15, and 17 N), and sizing machine speed (C) (30, 49, and 68 m/min), as well as three response variables (gain strength, loss elongation, and stretch), are considered. 15 samples of sized yarn have been produced with various combinations of the given factors, and the values of the response variables are measured for each sample. It has been observed that wet zone yarn tension and squeezing roller pressure have a significant effect on gain strength, stretch, and loss elongation. According to the regression analysis, gain strength has a negative relationship with wet zone yarn tension and a positive relationship with squeezing roller pressure. In the other case, both wet-zone yarn tension and squeezing roller pressure have a positive and significant effect on loss elongation and yarn stretch. At 340 N wet zone yarn tension, 13 N squeezing roller pressure, and 51 m/min sizing machine speed, the optimum values of gain strength (32.7 cN/tex), loss elongation (18.5%), and stretch (1.4%) were obtained. The methodologies employed in this study revealed the empirical relationship between the factors and the responses, the interaction effects of the factors on the responses, and multiple response optimizations. The optimized result of this study can be applied to the warp yarn sizing and can improve the tensile properties of the yarn and the loom’s efficiency significantly.

- Fatigue life prediction of 3D braided carbon/carbon composites with
braided angle variation at elevated temperature
Authors: Xinglin Yang, Shengyu Zhang, Bo Chen, Bingjie Ma, Xue Xing
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
The braiding angle of 3D braided carbon/carbon composites (C/CCs) will change during high temperature fatigue loading, which will affect the fatigue properties of 3D braided C/CCs. In order to realize this dynamic simulation in the high temperature fatigue life prediction of 3D braided C/CCs and further improve the prediction accuracy of high temperature fatigue life of 3D braided C/CCs, a high temperature fatigue life prediction model of 3D braided C/CCs considering the change of braiding angle with fatigue cycle number was established. The establishment of the prediction model mainly includes: a meso-scale representative volume elements (RVEs) of 3D braided C/CCs considering yarn direction and fiber bundle cross-section shape is established at the meso-scale; the high temperature residual stiffness and residual strength models of fiber bundles considering high temperature and stress level are established. Based on the experimental data characteristics of high temperature fatigue residual stiffness of 3D braided C/CCs, a mathematical model of cycle number/braided angles (CN/BAs) is established. The fatigue life prediction model was used to predict the 3D braided C/CCs at 700°C and stress levels of 87% and 85%. The results showed that the prediction error of single flower node was less than 5%. The fatigue life prediction error is less than two times the tolerance.

- A context-aware progressive attention aggregation network for fabric
defect detection
Authors: Zhoufeng Liu, Bo Tian, Chunlei Li, Xiao Li, Kaihua Wang
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
Fabric defect detection plays a critical role for measuring quality control in the textile manufacturing industry. Deep learning-based saliency models can quickly spot the most interesting regions that attract human attention from the complex background, which have been successfully applied in fabric defect detection. However, most of the previous methods mainly adopted multi-level feature aggregation yet ignored the complementary relationship among different features, and thus resulted in poor representation capability for the tiny and slender defects. To remedy these issues, we propose a novel saliency-based fabric defect detection network, which can exploit the complementary information between different layers to enhance the representation features ability and discrimination of defects. Specifically, a multi-scale feature aggregation unit (MFAU) is proposed to effectively characterize the multi-scale contextual features. Besides, a feature fusion refinement module (FFR) composed of an attention fusion unit (AFU) and an auxiliary refinement unit (ARU) is designed to exploit complementary important information and further refine the input features for enhancing the discriminative ability of defect features. Finally, a multi-level deep supervision (MDS) is adopted to guide the model to generate more accurate saliency maps. Under different evaluation metrics, our proposed method outperforms most state-of-the-art methods on our developed fabric datasets.

Authors: Sahar Kousar, Muhammad Babar Ramzan, Salman Arif Cheema, Sheraz Ahmad, Abher Rasheed, Nadeem Nasir
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
This study aims at the proposition of a novel strategy to classify the upper body silhouette of the male population into different shapes. Instead of using an existing measuring scheme based on linear evaluation of the body, we devise the use of angle-based anthropometric data to capture the exhibited curvature of the upper body. The objectives are attained by quantifying and employing the chest-waist (CW) angle and hip-waist (HW) angle in the instigation of a more appropriate classification of the upper body. A sample of 241 males aged 17–29 years was scanned through a 3D body scanner to gather the anthropometric data including chest girth, waist girth, and hip girth and their respective heights. In the next phase, the extracted information was used to calculate the angles. Based on the empirical realizations of the resulting indices, criteria defining the classifications of the body shape were determined. The operational environment is further enriched by considering varying levels of angular differences capable of offering more notable stratification of the upper male body shapes. It is realized that the angular difference of 10° between the CW and HW angles results in the more prominent classification of the upper male body. The proposed body classification technique classifies the sample of 241 males into three body shapes that are, straight (61%), hourglass (36.51%), and torch shape (2.48%). The classification scheme proposed in this study is a step toward achieving a high degree of customer satisfaction regarding clothing fit. It is a reference for coming research in body shape classification to achieve clothing fit in customized clothing.

textiles
Authors: Shuai Li
Abstract: Journal of Engineered Fibers and Fabrics, Volume 18, Issue , January-December 2023.
4D printed products can change shape under external stimulation, and the deformation design of material and structure is directly built into the material, which simplifies the manufacturing process from design concept to physical object and allows the object to be automatically assembled and conformed, realizing the integration of product design, manufacturing, and assembly. In recent years, 4D printing technology has also received widespread attention in the smart textile industry. This paper aims to promote the diversified and efficient development of the smart textile industry and expand the scope of the application of additive manufacturing technology. First, the evolution of 4D printing and its intrinsic relationship with 3D printing are examined. Then, the types of 4D printing smart textile technologies and their characteristics are presented, and the influence of relevant parameters of each type of technology on the molding quality, deformation mechanism, and driving performance of printed models is discussed. Materials for 4D printing of smart textiles are further described, including shape memory materials, hydrogels, and elastic liquid crystals. To adapt to the specific properties of textile applications, 4D printing technology has developed from the structural level of textiles to create smart textiles with adjustable shapes, properties, or functions. Then, the applications of 4D printed smart textiles in different fields are summarized. Finally, some problems currently faced by 4D printed smart textiles are discussed, and their prospects are projected.

- 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.

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.

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.

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.
