Negative Poisson's ratio materials or auxetic materials are fascinating materials, which expand laterally when stretched axially or shrink laterally when compressed. To date, a large number of materials with this characteristic have been discovered, made or investigated. These materials have unique properties which make them attractive for special applications. Till now, two general structures have been proposed which could be used either alone or in woven fabric structure. However, there are limited studies in the feld of auxitic woven fabrics. Several knitted structures with auxetic effect have been made from non-auxetic yarns. These fabrics have auxetic effect in limited range of tensile elongation. A number of auxetic 3D textiles have also been proposed for various applications.
