POLYESTER YARN

摘要

Polyester yarns whose polyester fibers are of simple oval peripheral cross section of aspect ratio at least about 1.85:1 have shown better dye yield in fabrics than polyester staple fibers having lower aspect ratios. Such superior cross sections for polyester staple fibers have also provided advantages in open-end spinning in providing yarns with fewer spinning failures than fibers of conventional round cross section.
