Abstract:
Continuous process for the production of monofilament fibers 23 having a diameter of 60 .mu.m to 2000 .mu.m from fibre-forming thermoplastic polymers by melt-spinning of the molten polymer from a spinning head 17, lateral quenching of the fibers 23 with cooling gas in a spinning cabinet 2, cooling of the formed fibers in a cooling liquid bath 5, removal of adhering cooling liquid 24, optionally applying a finish, stretching the fibers 23 in one or more stages, setting and winding the fibers 23 at a delivery speed of the set fibers 23 of 100 to 4000 m/min, wherein the cooling gas has a temperature of 0 to 50.degree. C., the cooling gas exhibits a defined velocity profile which decreases in the running direction of the fibers and the cooling liquid has a temperature of -10 to 150.degree. C.
