Abstract

Textile auxetic materials with negative Poisson’s ratio (NPR) have potential applications in protective textile, filtration, and energy absorbance. However, cotton core-spun based auxetic textile is rarely investigated. In this study, cotton core-spun (Lycra)-based helical auxetic yarn (HAY) was developed, and the effects of core filament linear density on the auxetic behavior were studied. Core-spun cotton yarns of 8/1 Nec containing core filament (180, 260, and 420 D) were developed. Then, these core-spun yarns were wrapped with 50 D Dyneema filament at 393 twist/m to make the HAY. The diameter, NPR, and tensile strength of HAY were increased with increasing linear density of Lycra filament. Image analysis of HAY containing 420 D Lycra showed 57% diameter increase with the change in axial strain from 0 to 15 mm. The maximum auxetic behavior with NPR of −3.97 and tensile strength of 26.71 cN/tex was observed in 420 D Lycra-based HAY. This study proved that the cotton core spun-based HAY can be produced with significant auxetic properties for practically potential use in wearable protective textiles.

Abstract

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.

3. Three-dimensional narrow woven fabric with in-plane auxetic behavior

Abstract

Different auxetic structures and auxetic phenomena are continuously explored by researchers in the field of textiles with enhanced properties for broader application areas. However, developing three-dimensional (3D) auxetic structures by using weaving technology is a real challenge compared to knitting and non-weaving techniques. This research work reports a novel approach to develop 3D woven structures with in-plane auxetic behavior. A conventional 3D multilayer orthogonal through-the-thickness structure was converted into a 3D auxetic woven structure. The structure was designed with three different yarn components to incorporate auxetic geometry. One type of yarn was used in the warp direction, while the other two-yarn systems, comprised of fine elastic yarn and coarse binding yarn, were used in the weft direction. The auxetic geometry achieved resembles the reentrant hexagon by the unusual arrangement of warp yarns. For an in-depth study of the structure, nine fabric samples were fabricated by using a conventional semi-automatic weaving machine with four different influencing parameters. The developed samples were then tested on a tensile testing machine to evaluate their mechanical and auxetic behavior. The results show that the 3D fabrics have a negative Poisson’s ratio (NPR) even at higher tensile strain and that the appropriate binding to the warp yarn diameter can produce a higher NPR. In addition, the repeat size of the elastic weft yarn, bending stiffness of the binding yarn, and stretch percentage of the elastic weft yarn can highly affect the NPR of the fabric. Furthermore, among all the 3D woven fabrics developed with different structural parameters, the maximum NPR achieved was –1.61.

4. Handbook of Stretchable and Elastomeric Textiles

Author

Abstract

Handbook of Stretchable and Elastomeric Textiles is a comprehensive guide to everything you need to know about elastomeric textiles, including manufacturing techniques, physical properties, processing methods, and in-use care. All types of stretchable textiles are covered, including polymers, fibers, yarns, fabrics and composites. Starting with the fundamentals of the synthesis, properties and processing of elastomeric materials, this book goes on to help the reader choose the most appropriate parameters for manufacturing and processing, as well as the best elastomeric material according to specific end use applications. In general, elastomeric textiles are difficult to handle. During the manufacturing of elastomeric fabric, the handling of yarns is complicated. In addition, the processing stage is also challenging due to the heat sensitivity of the materials that affects how they are dyed, printed, washed and dried. The specific techniques required to produce a successful elastomeric textile have been developed over many years, hence this expertise is hard to come by. - Provides foundational knowledge on the polymeric structure of elastomeric fibers - Explains how various materials can be used to prepare elastomeric fibers - Addresses how elastomerics are being used in wearables and smart textile technologies
