    摘要: The invention relates to a method and device for producing Lyocell fibres from a spinning solution containing water, cellulose and tertiary amine oxide. The spinning solution is extruded to form spun threads (10). The spun threads (10) are stretched and passed through a precipitation bath (16) in order to precipitate the cellulose. It has been surprisingly revealed that the tenacity of the Lyocell fibres produced in this way can be increased when the stretched fibres are subjected to post-stretching in a post-stretching means. The post-stretched Lyocell fibres have a wet modulus of at least 260 cN/tex.

    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.

    摘要: The invention relates to a method and a device for producing Lyocell fibers, which are extruded from a spinning mass containing water, cellulose and tertiary amine oxide. The spinning mass is obtained from cellulose in a number of process steps, wherein a treatment medium is added to the cellulose, cellulose suspension and/or cellulose solution. In order to be able to implement a stable and environmentally compatible spinning method irrespective of the type of cellulose used, according to the invention, provision is made that the content of at least one type of metal ion destabilising the cellulose suspension and/or cellulose solution is monitored in the cellulose, cellulose suspension and/or cellulose solution and adjusted below a stability limit. With the device according to the invention, the metal ion content is measured via sensors (23, 23′) and the metal ion content is adjusted using a control device (17).
