New heather yarns having pleasing aesthetics

摘要

Flat heather polyester yarns that provide soft pleasing fabrics that can easily be brushed (or napped) to enhance their aesthetics, on account of their unusually low tenacity, that consist essentially of cationic dyeable polyester filaments with homopolymer filaments, and corresponding spin-oriented feed yarns that may be processed into such flat yarns by draw-warping.
