Abstract
Negative Poisson’s ratio textiles have expanded deformation behavior and special mechanical properties under tension. According to the previous research, the negative Poisson’s ratio effect of fabrics was always lower than yarns. The main reason was that negative Poisson’s ratio yarns showed little structural deformation because of the fabric structures. In this study, chain stitch structure fabrics with negative Poisson’s ratio yarns as inserted weft yarns were designed and prepared. The effect of inserted weft yarns, symmetrical and parallelization arrangement and density on the Poisson’s ratio of chain stitch fabrics were tested and analyzed. The results showed that the negative Poisson’s ratio effect of fabrics was as similar as yarns and yarns in fabric. When the knitting loops provided fixation role in the fabrics, the negative Poisson’s yarns could also present obvious deformation behavior to successfully improve the expand effect of fabrics. Poisson’s ratio and porosity of fabrics under cyclic stretching were carried out to study the structure and property stability. The chain stitch structure fabrics with negative Poisson’s ratio are expected to provide more choices for improving the property and applicability.
