Auxetic textiles are extraordinary materials that become fatter when stretched, yet their fabrication has been limited by deployment challenges and the lack of engineered functional fabrics despite several proposed geometrical configurations. The study aims to engineer auxetic textiles by integrating geometric design with fabric structural characteristics to determine their properties. The authors develop a warp‑knit technique that uses a base chain with two to six guide bars and filling yarn inlays to create compound repeating units. They present the resulting knit structures, demonstrating that the filling yarn inlays effectively produce auxetic behavior in the fabricated fabrics. Keywords include auxetic textiles, negative Poisson's ratio, warp knitting, fabric geometry, structural properties, and the study was funded by the National Textile Center under US Department of Commerce Grant 02–07400.
Abstract Auxetic textiles belong to a class of extraordinary materials that become fatter when stretched. Sustained efforts to fabricate auxetic fabric structures are limited. Indeed, several geometrical configurations have been previously proposed but none has been engineered into functional auxetic textile fabrics. The use of auxetic materials has been limited because of problems with deploying them in their fabricated forms. Our thrust in this research is to combine our knowledge of geometry and fabric structural characteristics to engineer auxetic textiles and to determine the properties of such auxetic textile fabrics. In this paper, we have presented the technique we developed for producing several knit structures in which filling yarn inlays are used to effect compound repeating units. In these productions, the chain is used as a base structure and a minimum of two guide bars and maximum of six guide bars are deployed to produce such warp knit auxetic fabrics.
