METHOD FOR PRODUCING FINE MONOFILAMENTS CONSISTING OF POLYPROPYLENE, FINE MONOFILAMENTS CONSISTING OF POLYPROPYLENE AND THE USE THEREOF

摘要

The invention relates to a method for producing fine monofilaments with an improved abrasion resistance from a polypropylene with a melt fusion index (MFI) 230 DEG C/12.16 kg of 2-16g/10 min to a titer of 5-20 dtex (0.027 mm-0.053mm). According to said method, a compound of 80 to 99.9 wt. % granulate and 20 to 0.1 wt % of an additive is added to the extruder, the melt is spun at a speed of at least 1200 m/min, cooled in an air bath at room temperature, stretched at a temperature of between 110 and 150 DEG C to a titer of 5-20 dtex and wound. The monofilaments consisting of a polypropylene with a melt fusion index (MFI) 230 DEG C2.16 kg of 2-16g/10 min, improved abrasion resistance and a titer of 5-20 dtex (0.027 mm-0.053mm) have an abrasion resistance
