Abstract
A method for manufacturing a textured synthetic multifilament yarn having alternately grouped S and Z twists. The textured yarn is produced by a conventional false-twist operation under a processing temperature between a softening point and a melting point of the material yarn in a first step and then the above-mentioned yarn is subjected to a process for separating individual filaments in each of the compact portions under tension.
