ABSTRACT:
A fibrous strand including at least some short fibers and composed of two or more kinds of fibers of different melting point temperatures is, concurrently with false twisting, and in a vibrating condition, heated by a heater of the non-contact type at temperatures between the highest and lowest melting point temperatures of the component fibers so as to produce spun-like yarns of a substantially twistless configuration containing uniformly scattered points of inter-fiber binding and fibers crimped in the form of a coil.
