    • The invention relates to a method and a device for producing lyocell fibres, which are extruded from a cellulose solution consisting of water, cellulose and a tertiary amino oxide in a spinning head (25). The cellulose solution is obtained directly in several method steps from the cellulose (3, 4), forming a cellulose suspension. As during the course of the processing of the cellulose, the degree of polymerisation reduces until the cellulose is extruded in the cellulose solution, there is a risk that the continuous moulded bodies (2) that are extruded by the spinning head (25) are of a poor quality. The aim of the invention is to process cellulose (3, 4) with a low degree of polymerisation, without having to sacrifice the quality. To achieve this, the residence time of the cellulose from its introduction into the device (1) until the extrusion of the cellulose (3, 4) in the cellulose solution is adjusted based on the degree of polymerisation of the cellulose, the cellulose suspension and/or the cellulose solution. ® KIPO & WIPO 2007

    • The invention relates to a method and a device (1) for producing a cellulose solution that can be extruded to form continuous moulded bodies (2). According to the invention, a cellulose suspension is produced in a pulper (5), from cellulose (3, 4) and water (6), and is then pressed by a pressing means (10). Once the cellulose suspension has been pressed, a tertiary amine oxide, especially N-methylmorpholine-N-oxide, is supplied as a solvent in order to obtain a cellulose solution. The cost-efficiency and the ecofriendliness of the inventive method and device can be improved by at least partially recirculating the press water (11) pressed by the pressing means (10) to the pulper (5). Furthermore, the proportion of press water (15) to water (6) varies according to the metal content of the cellulose (3, 4) and/or the cellulose solution. ® KIPO & WIPO 2007
    • 本发明涉及一种用于生产纤维素溶液的方法和装置(1),该纤维素溶液可被挤出以形成连续成型体(2)。 根据本发明,在碎浆机(5)中由纤维素(3,4)和水(6)生产纤维素悬浮液,然后用压制装置(10)压制。 一旦纤维素悬浮液被压制,就提供叔胺氧化物,特别是N-甲基吗啉-N-氧化物作为溶剂,以获得纤维素溶液。 通过至少部分地将压榨装置(10)压榨的压榨水(11)再循环到碎浆机(5)中,可以提高本发明的方法和装置的成本效率和生态友好性。 此外,按压水(15)与水(6)的比例根据纤维素(3,4)和/或纤维素溶液的金属含量而变化。 ®KIPO&WIPO 2007
