Abstract

A method and apparatus for producing multi-colored crimped yarns is disclosed, and which includes the steps of spinning a plurality of differently colored groups of filaments, subjecting the filaments of each group to a treatment liquid, and then combining the filaments to form respective strands. Each strand is then subjected to an air tangling process, then stretched and the strands are thereafter combined in a thermo-pneumatic texturizing process. This processing sequence produces multi-filament yarns with good color blending.
