Abstract (en)
[origin: WO9502082A1] The invention concerns a method of manufacturing cellulose fibres by extruding a solution of cellulose in a tertiary-amine oxide through the holes of a spinneret and passing the extruded filaments under tension through an air gap and into a regenerating bath. 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<2> - 7.18xT - 0.094xL - 2.50xF + 0.045xF<2> 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.
