Abstract The invention concerns a process for the production of cellulose fibres by extruding a solution of cellulose in a tertiary amine-oxide through spinning holes of a spinneret and conducting the extruded filaments across an air gap into a precipitation bath while drawing them, characterized in that the process is carried out in a way that the mathematical expression 51,4 + 0,033xD + 1937xM2 - 7,18xT - 0,094xL - 2,50xF + 0,045xF2, wherein D is the spinning hole diameter in µm, M is the dope output per hole in g/min, T is the titer of the individual 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/kg of air, does not exceed the number 10, with the provision that the length of the air gap is provided greater than 30 mm. That process leads to cellulose fibres having a very weak tendency to fibrillation. |
