POLYESTER-BASED STRETCHABLE WOVEN FABRIC

摘要

PROBLEM TO BE SOLVED: To obtain a polyester-based stretchable woven fabric excellent in stretchability and further grade without crinkles. SOLUTION: This polyester-based stretchable woven fabric is obtained by using a yarn prepared by twising a multifilament yarn of conjugate fibers prepared by laminating two kinds of polyester-based polymers in which one consists essentially of polytrimethylene terephthalate in a side by side type in the fiber longitudinal direction at 3,000-15,000 twist multiplier K represented by the following formula as at least one of warp yarns and weft yarns and has >=15% woven fabric extension ratio in the direction using the yarn. T=K×[1/D1/2] [T is the number of twists per m; D is the fineness of the yarn (dtex)×0.9].
