ABSTRACT:
A spun-type yarn having a unique configuration and useful properties is manufactured by a novel process which comprises forming a ribbon-shaped fiber bundle being substantially free from twists and composed of randomly oriented continuous filaments, each of which comprises random bends and loops along its length, and then false twisting the ribbon-shaped bundle to consolidate it into a yarn. In the false-twisting, some of the filaments are broken.
