摘要： The invention relates to a process for the manufacture of cellulose fibres, during which a solution of cellulose in a tertiary amine oxide is extruded through holes of a spinneret, thereby forming filaments. The extruded filaments are conveyed through an air gap, a regeneration bath and over a take-off device used to draw the filaments, the drawn filaments being subsequently processed to form cellulose fibres. During subsequent processing, said drawn filaments are subjected to a tensile stress in the longitudinal direction which is not greater than 5.5 cN/tex.

摘要： In a process for manufacturing cellulose moulded bodies, cellulose is dissolved in a mixture of a tertiary amine oxide and a non-solvent for cellulose, for example water, the solution is extruded through a shaping tool and the thus obtained filaments are drawn through an air gap into a regenerating bath. The process is characterised in that the regenerating bath essentially consists of a non-aqueous solvent for tertiary amine oxide having a molecular weight higher than that of the tertiary amine oxide. Solvent-spun fibres with hardly any fibrillation tendency may thus be obtained. Polyethylene glycols are preferably used.

摘要： The invention concerns a method of producing cellulose fibres, the method calling for a warm solution of cellulose in a tertiary-amine oxide to be spun into filaments which are passed across an air gap and then brought into contact with a precipitating agent in order to precipitate the cellulose, the filaments being drawn off by the action of a force which stretches them in the air gap. The force is exerted by the precipitating agent by virtue of the fact that the precipitating agent is allowed to flow in the direction in which the filaments are to be drawn off and brought into contact with the precipitating agent. The method is characterized in that, when the precipitating agent is brought into contact with the filaments, it is allowed to flow at a speed which is at least as great as the speed at which the filaments are drawn off. The invention also concerns a device for carrying out the method.

摘要： In order to produce a cellulose moulded body, a solution of cellulose in a tertiary amine oxide is moulded in the warm state and the solution thus moulded is fed into a precipitation bath after coding to precipitate the cellulose contained therein. Coding takes place immediately after moulding and is done preferably by blowing air horizontally onto the cellulose moulded body. The process according to this invention facilitates spinning of the cellulose solution with a high yarn density while preventing jamming of the spun yarns when leaving the spinning nozzle. It also allows, despite the high yarn density, a large air gap to be left between the spinning nozzle and the precipitating bath, which leaves adequate time to modify the textile characteristics of the yarns by drawing them as they leave the spinning nozzle.
摘要翻译：为了制造纤维素成形体，在温热状态下将纤维素在叔胺氧化物中的溶液成型，将这样成型的溶液进行编码后的沉淀浴中，使其中含有的纤维素析出。编码在模制之后立即进行，并且优选通过将空气水平地吹送到纤维素模制体上来进行。根据本发明的方法有助于以高纱线密度纺丝纤维素溶液，同时防止纺丝纱线离开纺丝喷嘴时的干扰。即使纱线密度高，纺丝喷嘴和沉淀槽之间仍然留有大的气隙，这样留下足够的时间来通过在离开纺丝喷嘴时将丝线的纺丝特性拉出来。
