Abstract
The capability of predicting the tensile properties of textured yarn fabrics when they are stretched biaxially to equal extension ratios along warp and weft direction is discussed under the tensile force below 500gf/cm. This force region is related to the handle of fabrics.
Textured yarns are featured with their high stretchability, which makes it difficult to calculate the tensile properties of textured yarn fabrics because the initial extension state of yarns in the fabaric is uncertain. We define this initial extension of yarn, and then calculate the biaxial tensile properties of textured yarn fabrics by applying the biaxial tensile theory by Kawabata et al. Specimens made of nearly flexible yarns showed a good agreement between calculated values and experimentals.
