PROBLEM TO BE SOLVED: To provide a woven fabric imparted with delicate crisp feeling in addition to the characteristic features of cellulosic fibers, glossiness and moisture absorbing and releasing property, by using a yarn based on a cellulose derivative as a sheath yarn and performing slub-tone composite false-twisting treatment. SOLUTION: The slub-tone composite false-twist yarn has a part in which a yarn (b) positioned at the sheath part is singly wound around a yarn (a) positioned at the core part and a part in which the sheath yarn is triply wound around the core yarn, and the singly wound parts and the triply wound parts are alternately arranged in the longitudinal direction of the false-twist yarn. The yarn (b) is composed of a cellulose ester composition composed mainly of a cellulose ester having 3-18C acyl groups substituting at least a part of hydroxyl groups. COPYRIGHT: (C)2008,JPO&INPIT
