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.

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.

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.

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.

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.

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.

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.

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.

A new knitting process is presented based on a novel yarn feeding technique. It allows the knitting of new structures: single jersey on one or both needle beds and rib structure on both needle beds in the same knitting cycle, that is the same needles. The innovative knitted fabrics were compared to standard 1 × 1 rib and plain woven fabrics made from the same material. All samples were tested for physical (grammage, air permeability), morphological (number of stitches per centimetre in wale and course directions and number of stitches per square centimetre, cover factor) and mechanical (uniaxial and multidirectional tensile behaviour) properties. Grammage was used as a reference parameter to render the results comparable. The results show that the innovative fabrics are less stretchable than the standard knitted fabrics, especially in the course direction, therefore more rigid in this direction. Furthermore, they can be mechanically balanced in course and wale directions, which is unexpected for knitted fabrics. The innovative knitted fabrics are thicker than the standard knitted fabrics for the same grammage and have a lower number of stitches per square centimetre, enabling higher production rates. Due to their lower cover factor, the innovative fabrics are expected to be easier to impregnate by resin for composite applications than the standard knitted fabrics. Based on these results and the ability to increase knitting productivity, we conclude that that this novel process can transform future processes and open the door to new markets and applications.

All samples were tested for physical (grammage, air permeability), morphological (number of stitches per centimetre in wale and course directions and number of stitches per square centimetre, cover factor) and mechanical (uniaxial and multidirectional tensile behaviour) properties. Grammage was used as a reference parameter to render the results comparable. The results show that the innovative fabrics are less stretchable than the standard knitted fabrics, especially in the course direction, therefore more rigid in this direction. Furthermore, they can be mechanically balanced in course and wale directions, which is unexpected for knitted fabrics. The innovative knitted fabrics are thicker than the standard knitted fabrics for the same grammage and have a lower number of stitches per square centimetre, enabling higher production rates. Due to their lower cover factor, the innovative fabrics are expected to be easier to impregnate by resin for composite applications than the standard knitted fabrics. Based on these results and the ability to increase knitting productivity, we conclude that that this novel process can transform future processes and open the door to new markets and applications.","PeriodicalId":15718,"journal":{"name":"Journal of Engineered Fibers and Fabrics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135008489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
