| titleOfInvention | Lyocell method comprising an adjustment of the processing duration based on the degree of polymerization |
| abstract | The invention relates to a method and a device for producing Lyocell fibers which are extruded from a cellulose solution of water, cellulose and tertiary amine oxide in a spinning head ( 25 ). The cellulose solution is obtained in a number of process steps directly from the cellulose ( 3, 4 ) or with the formation of a cellulose suspension. Since the degree of polymerization decreases in the course of processing the cellulose through to its extrusion in the cellulose solution, with the processing of celluloses with a low degree of polymerization there is the risk that the endless molded bodies ( 2 ) extruded in the spinning head ( 25 ) exhibit defective quality. In order to also be able to process celluloses ( 3, 4 ) with a low degree of polymerization without having to accept reduced quality, according to the invention, the residence time of the cellulose from its introduction into the device ( 1 ) through to the extrusion of the cellulose ( 3, 4 ) in the cellulose solution is set in dependence of the degree of polymerization of the cellulose, of the cellulose suspension and/or of the cellulose solution. |
