| Abstract: | The texturing process conditions for 0 5 dtex superfine polypropylene filaments, such as the variety and combination of friction disks, drawing temperature, draw ratio and texturing speed etc., were studied. The optimal texturing process conditions were determined as: the first heat box temperature 125℃, texturing speed 400 m/min, draw ratio 1 15, polyurethane friction disk and the combination of 1\|4\|1. The 72\|hour trial running yielded 87% finished fiber rate and 81% first\|quality percentage. |
