“…Highly stretchable auxetic fabrics have also been proposed and fabricated by researchers using helical auxetic yarn [189,190]. Woven fabrics formed with helical auxetic yarns showed self-folding and self-curling behavior in the natural state [189]. When stretched, this woven fabric showed the maximum Poisson's ratio value of −0.3 at a strain value of 200%.…”

Auxetic materials belong to a class of well-organized manmade materials that possess negative Poisson’s ratio when applied load. Typically, they consist of periodic unit cells that show low Young’s and bulk moduli due to their unique structure. Thus, most of the classical auxetic materials exhibit soft behavior. Recently, some of the works investigated auxetic materials with stiff mechanical behavior. In this paper, we review auxetic structures and design methods to design soft or stiff auxetic materials, as well as their potential applications. Generally, auxetic materials fabricated using soft base material or curved microstructural ribs possess soft behavior, while auxetic materials fabricated using hard base material or adding additional ribs in the original microstructure possess stiff behavior. Possible study areas in the future for the soft and stiff auxetic materials are also presented.

“…They pointed out the yarn arrangement, yarn properties, weft yarn type, weave structure and yarn helical structure have significant effect on the NPR of the fabric. Then, Du's group reported a self-curling and self-folding auxetic woven fabric experimentally with the maximum NPR of -0.585 [32,33]. It was noted that such woven fabrics demonstrate a good auxeticity, low elastic deformation, high flexibility and breaking load.…”

The paper presents a study on woven fabrics made of helical auxetic yarns (HAYs) and their key factors on Poisson’s ratio under tension. The work aims to create and evaluate auxetic woven fabrics with optimal parameters for achieving better auxeticity including weave structure, wrapping angle of the auxetic yarn, thickness of the auxetic yarn and properties of the warp yarn. The maximum negative Poisson’s ratio (NPR) of the woven fabric can be achieved as low as -2.92 for experiments. Then, a numerical study has been carried out as well to assist the development of auxetic woven fabrics. The findings of this paper showed longer float length, lower wrapping angle of the auxetic yarn, a thinner diameter of the auxetic yarn as well as lower tensile modulus of the warp yarn led to higher auxetic behaviour. This can also provide a reference for researchers to select the best parameters for producing the auxetic woven fabrics.

“…More recently, Liu et al. 20 compared the auxetic performance of woven fabrics made from pointed twill and diamond twill to that of the plain fabrics. The maximum NPR achieved was −0.3 under diagonal tensile loading with the strain of 200%.…”

Auxetic textiles, as one of the synthetic auxetic materials, have attracted much research interest in recent years due to their material adaptability and structural variability. Based on the experimental results reported in our previous papers, the auxetic behavior of woven fabrics was further investigated and the key factors affecting weaving the fabrics were studied systematically by using a combination of experiments and numerical simulation. In this paper, different types of woven fabrics were compared based on finite element analysis and the key parameters influencing the Poisson’s ratio were analyzed, including the helical auxetic yarn (HAY) arrangements, fabric density, helical angles of the HAY, thickness of the HAY, weave structures, warp yarn types and loading directions. The auxeticity of the fabrics was first analyzed out-of-plane and in-plane. The results showed that the maximum negative Poisson’s ratio can be achieved as −3.57 out-of-plane and −1.17 in-plane. The out-of-plane auxeticity of the fabric is notable, which could provide a reference for industry and researchers for potential applications.
