ABSTRACT:
A synthetic multifilament textured yarn provided with randomly formed compact portions and bulky portions formed between two adjacent compact portions. The compact portions are provided with a certain twist and the bulky portions consist of a plurality of individual filaments, each having random crimps. Each of said individual filaments are separated from each other, and the twist direction of each of said bulky portions is opposite from that of two adjacent compact portions. This textured yarn can be produced by a conventional false-twist operation under a processing temperature between a softening point and a melting point of the material yarn.
