Abstract
Spunlike yarns having free ends are made from continuous filament yarn by fluid-jet texturing. The fibrous elements that make up the yarn have irregular and varying cross-sectional shapes, said fibrous elements being forked and merged in a fortuitous manner. The spunlike yarns may also contain fibrous elements that extend substantially continuously throughout the length of the yarn.
