Abstract

Polypropylene is melt-spun and drawn at high speed and wound up. It has melt index i5 of 50-500 at 230 degrees C. SPinneret hole diam. is 0.5-1.5 mm. Fibre denier is 5-20. Cooling is by cross air stream and windup is pneumatic at >=0.05 g/den, 4-15 m below spinneret, at 2500-9000 m/min. windup and drawing speed. Filaments are wound on air-permeable takeup device under reduced pressure of hydraulic head >=50 mm.
