用于生产纤维素成型体，纤维素的氧化胺溶液强制通过模头，然后通过气隙，吸入如果有的话，最后在沉淀浴中凝固。 根据本发明，所使用的喷嘴的最小孔径为至多150微米，优选为至多70微米，和喷嘴通道的长度为至少1000微米，优选约1500微米。 特征的气隙的长度以小于35mm或甚至小于10mm可以减小，因为它可以在不进行由于Langkanaldüse的取向与没有生产的纤维的织物性能的降低率受到影响。 在渐缩的入口侧，并且仅在出口侧圆柱形的喷嘴通道的一个优选实施例。

For producing a cellulosic molded body, a cellulosic amine oxide solution is forced through a die and then passed through an air gap, is stretched in this where appropriate, and finally coagulated in a precipitation bath. According to the invention, the minimum hole diameter of the die used at most 150 microns, preferably at most 70 microns and the length of the nozzle channel is at least 1000 microns, preferably about 1500 microns. As a result, the length of the air gap to less than 35 mm or even 10 mm reduced, as it may be coming due to an orientation in the Langkanaldüse with a lower default without the textile properties of the fibers produced are suffering. In a preferred embodiment of the nozzle channel this is conical on the inlet side, and only on the exit side of a cylinder.
