ABSTRACT:
A roving formed from a first kind of staple fibers, each of which is at least 3 denier, is interposed with a randomly mixed sliver formed from a second kind of staple fibers, each of which is between 1.5 denier and 3 denier, and a third kind of staple fibers, each of which is at most 1.5 denier, the thermal shrinkage of the second kind of staple fibers being higher than that of the third kind of staple fibers. The roving and the randomly mixed sliver are twisted together so that the sliver wraps around the roving in order to form a double layered roving. After the double layered roving is subjected to fine spinning, it is then subjected to a heat treatment. As a result, a multi-layered bulky spun yarn is obtained.
