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.

The method is characterized in that it is carried out in such a way that the maximum value of the mathematical expression 51.4 + 0.033xD + 1937xM - 7.18xT - 0.094xL - 2.50xF + 0.045xF in which D is the spinneret-hole diameter in mu m, M is the spinning-solution throughput per hole in g/min, T is the titre of a single filament in dtex, L is the length of the air gap in mm and F is the humidity of the air in the air gap in g of water per kg of air, is 10, with the provision that the length of the air gap is greater than 30 mm. This method gives cellulose fibres with a very low tendency to fibrillation.
