A method is provided for simultaneous spin-drawing of continuous yarns
consisting of one or more filaments, comprising the steps in which a melt
of a thermoplastic material is fed to a spinning device, the melt is
extruded through a spinneret by means of extrusion openings with the
formation of continuous yarns, the continuous yarns are cooled by feeding
them through a first and a second cooling zone, wherein the continuous
yarns are cooled essentially by a stream of air on passing through the
first cooling zone and essentially by a fluid, consisting wholly or
partly of a component that is liquid at room temperature, on passing
through the second cooling zone, and the continuous yarns are then dried,
subsequently drawn and wound up by means of winding devices, the method
being distinguished in that the continuous yarns are fed through the
first and second cooling zones at a speed of up to 500 m/min and that the
residence time of the continuous yarns within the first cooling zone is
at least 0.1 sec.
