| 摘要 |
The invention relates to a method and a device ( 1 ) for the production of a cellulose solution, from which endless moulded bodies ( 2 ) can be extruded. First, a cellulose suspension is produced from cellulose ( 3, 4 ) and water ( 6 ) in a pulper ( 5 ). The cellulose suspension is then expressed by a press device ( 10 ). After expressing, a tertiary amine oxide, in particular N-methylmorpholine-N-oxide, is fed as a solvent to the cellulose suspension, thus producing a cellulose solution. The efficiency of the method and the device and their environmental compatibility can be improved in that the press water ( 11 ) expressed by the press device ( 10 ) is at least in part fed back to the pulper ( 5 ). In a further development the proportion of the press water ( 15 ) in the water ( 6 ) is varied depending on the metal content of the cellulose ( 3, 4 ) and/or of the cellulose solution.
