<p>A process for the production of polyamide-6-filaments of the ?-modification The invention is related to a process for the production of continuous polyamide-6-filaments present in the ?-modifi-cation both before and after stretching at room temperature by spinning polyamide-6 with a relative solution viscosity of from 2.3 to 3.1, preferably from 2.6 to 2.85, as measured on a 1 % solution in m-cresol, wherein the filaments a) after leaving the spinneret, are cooled by air-blowing and preoriented up to an elongation at break of from 50 to 80 %, preferably from 55 to 75 %, by being run off, preferably in the absence of godets, at a speed of 3700 to 4500 m/min;b) before winding into package form and during take-off, are prepared with an aqueous preparation oil in such a way that they contain less than 3.0 % by weight of water, and c) before winding into package form are subjected to interlacing.</p> |
