Abstract (en)
[origin: WO9842900A1] The present invention concerns a method for producing round polyamide monofilaments which are free of pinholes and heat-resistant for use in technical fabric. A mixture of 75 to 85 wt-percent-PA 66 and more than 15 to 25 wt-percent-PA 6 is produced immediately prior to extrusion, spun, and immediately cooled in a liquid. The monofilament in a titer range from 0.8 to 1.5mm diameter is intended for technical fabric and has a resistance greater than 40 cN/tex, a thermal resistance of </=55 %, and a melting point range between 235-260 DEG C.
