Abstract

A process is described for producing fibres from polymers which give off troublesome gases and/or vapours during spinning, comprising the steps of: a) extruding the molten polymer through a spinneret (dies) into a closed spinning shaft (chimney, cell), b) quenching the resulting filaments in the spinning shaft with a gas, c) withdrawing the resulting filaments from the spinning shaft, d) conducting the quench gas away from the spinning shaft and introducing it into a gas purification system and e) purifying the used quench gas by contact with an adsorbent for said troublesome gases and/or vapours. It is possible by the present invention to keep hazardous gases occurring during the spinning of polymers away from the surroundings and to dispose of them. Suitable polymers are in particular polyphenylene sulphides. The invention further relates to an adapted apparatus for carrying out the process according to the invention. The apparatus comprises an extruder (1), a spinning pump (2) and a spin pack (3) which contains a filter (4) and spinnerets (5). The spinnerets (5) open out directly into a closed spinning shaft (6) which is provided with at least one feedline (7) and one discharge line (8) for the quench gas. In the representation of Figure 1, two discharge lines (8) for the quench gas are depicted at the top and bottom end of the spinning shaft. In addition, in this Figure 1, an auxiliary extraction line (12) is furnished for the quench gas which is mounted at the bottom end of the spinning shaft next to the outlet orifice for the filaments. In the representation of Figure 1, all discharge lines for the quench gas are equipped with a gas purification system (9). <IMAGE>
