To produce a cellulosic shaped body, a cellulosic amine oxide solution is pressed through a nozzle, then passed through an air gap, optionally stretched therein and finally coagulated in a precipitation bath. According to the invention, the minimum hole diameter of the nozzle used is at most 150 μm, preferably at most 70 μm, and the length of the nozzle channel is at least 1000 μm, preferably about 1500 μm. As a result, the length of the air gap can be reduced to less than 35 mm or even less than 10 mm because, as a result of an orientation in the long-channel nozzle, less warpage can be achieved without the textile properties of the fibers produced suffering. In a preferred embodiment of the nozzle channel, it is conical on the inlet side and cylindrical only on the outlet side. |
