Equal Biaxial Tensile Properties of Textured Yarn Fabrics

Abstract

The capability of predicting the equail biaxial tensile properties of the textured yarn fabrics was discussed in the region of the tensile strength below 500 gf/cm. This value is related to the handle of the fabrics.The textured yarn has such a good feature as the high stretchability, but this makes difficult for the calculation of the tensile properties, because the initial extension state of the yarn in the fabric is uncertain. So, we defined the initial extension state and we could calculate the equal biaxial tensile properties of the textured yarn fab rics by applying the biaxial tensile theory by Kawabata et al.The specimens, which had nealy flexible yarns, showed a good agreement between the calculated values and the experimentals. But, we also found that the bending rigidty of the yarns in the fabric played an important role when we calculated the tensile properties of the fabrics.
