Abstract

A process for making filament yarn products is disclosed in which polypropylene, having a molecular weight distribution of less than about 7 and a melt index between about 20 and about 60 is melt spun to produce an as-spun product or additionally interlaced before take-up, twist-drawn, heat set, draw-textured by false-twisting, simultaneously draw-textured, sequentially draw-textured, draw-twisted, draw-Taslan textured, stuffer box crimped and cut into staple fibers, or a plurality of yarns are simultaneously draw-textured by false-twisting while reversing the direction of twist of alternate yarns and thereafter interlacing. Products of improved tenacity, improved birefringence and low elongation are produced.
