Process of making fiber for carpet face yarn

摘要

The specification describes a process of making a fiber for a carpet face yarn, the yarn being made of polyolefin/polymer filaments which contain a plurality of longitudinally dispersed relatively small, short polymer fibrils inside the filaments generally concentrated toward the center thereof within the polyolefm matrix. The yarn has the stain resistant properties of polyolefm based yarns and the resiliency of polyamide based yarns at a substantially lower cost than nylon carpet yarns.
