摘要： A method is provided for spinning a multifilament thread from a thermoplastic material, including the steps of extruding the melted material through a spinneret with a plurality of spinneret holes into a filament bundle with a plurality of filaments, winding the filaments as thread after solidifying, and cooling the filament bundle beneath the spinneret, whereby in a first cooling zone the gaseous cooling medium is directed in such a way that it flows through the filament bundle transversely, the cooling medium leaving the filament bundle practically completely on the side opposite the inflow side, and in a second cooling zone beneath the first cooling zone, the filament bundle being cooled further essentially through self-suction of the gaseous cooling medium surrounding the filament bundle.

摘要： A method is provided for spinning a multifilament thread from a thermoplastic material, comprising the steps of extruding the melted material through a spinneret with a plurality of spinneret holes into a filament bundle with a plurality of filaments, winding the filaments as thread after solidifying, and cooling the filament bundle in two steps beneath the spinneret, whereby in a first cooling zone the gaseous cooling medium is directed in such a way that it flows through the filament bundle transversely the method being characterized in that the cooling medium leaves the filament bundle practically completely on the side opposite the inflow side, and in a second cooling zone beneath the first cooling zone the filament bundle being cooled further essentially through self-suction of the gaseous cooling medium surrounding the filament bundle.

摘要： The invention pertains to a process for preparing thermoplastic fibres by melt-spinning an alternating co-polymer composed of alkenes and carbon monoxide in which the polymer is heated to a temperature of at least TNF+5° C., with TNF being the temperature at which the molten polymer is free of crystallization nuclei, and where the residence time of the polymer at a single temperature or different temperatures above the polymer melting point satisfies: [ ∑ n = 1 ∞ ⁢ t n · exp ⁢ ⁢ ( A + B T n ) ] ≤ 1. wherein tn is the residence time (in minutes) of the polymer at a temperature Tn (in K, with Tn>Tm) and A and B are determined by measuring the viscosity of the polymer at different temperatures and residence times.
