Date Jan. 19, 1995Disclosed is a process for producing cellulose fibers having a decreased tendency to fibrillate. The process comprises the steps of extruding a solution of cellulose in a tertiary amine-oxide through spinning holes of a spinneret to form cellulose filaments, conducting the extruded cellulose filaments across an air gap of greater than 30 mm, and introducing the cellulose filaments into a precipitation bath. 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, does not exceed the number 10. In the mathematical expression, D is the spinning hole diameter in mu m, 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.
