TWIST YARN WOVEN FABRIC

PROBLEM TO BE SOLVED: To provide a twist yarn woven fabric of a polyester filament free from characteristic slimy feeling of polyester filament and having the feeling of natural fiber fabric comprising the bulkiness, drape property and crispness. SOLUTION: The yarn constituting at least the warp of the woven fabric satisfies the following conditions (1) to (4) and the ratio of the floating yarn of the warp and the weft in the repeating unit texture of the woven fabric is >=1.0. (1) The yarn is composed of two kinds of filament groups having a yarn length difference of >=3% and the yarn has a core-sheath structure containing the longer filament group as the sheath yarn and the shorter filament group as the core yarn, (2) the number of filaments of the filament group constituting the core yarn is >=15 and the number of the filaments of the filament group constituting the sheath yarn is larger than that of the core yarn, (3) the filament of the sheath yarn has dents on the surface and (4) the yarn is twisted at a twist coefficient K of 8,000-23,000.
