  • Integrated spin-draw-texturizing process for manufacture of texturized polyamide filaments
    Patent number: 4096226
    Abstract: Integrated process for continuous spinning, drawing and texturizing of synthetic linear high molecular weight polyamide polymers, in which the following steps are effected in immediate succession:(a) melt-spinning filaments of said synthetic linear high polyamide polymers, preferably poly-.epsilon.-caprolactam, at temperatures of between 260.degree. and 295.degree. C and a spin-draw ratio of between 1:10 and 1:60,(b) drawing the spun filaments on at least two forwarding elements, of which the initial element has a surface temperature of between 50.degree. and 120.degree. C and the final element has a surface temperature of between 80.degree. and 350.degree.
