Abstract
Moresque or berber continuous filament yarn is prepared by supplying a first group of continuous filaments to a first entangling zone where harsh nodes are created so that the first group has a yarn harshness of at least about 200. One or more other groups of continuous filaments, which are differentially precolored or dyeable with respect to the first group, are joined to the first group and interlaced sufficiently to cohere all groups of continuous filaments without blending with the tightly interlaced first group. The finished yarn has node harshness less than 100.
