Process for the manufacture of filaments of regenerated cellulose, characterized in that it comprises adding to the viscose from 0.5 to 10% by weight, with respect to the weight of the cellulose, of a compound soluble in water and of an average molecular weight comprised between 300 and 10,000 can be obtained by the action of ethylene oxide on an aliphatic acid, amide, alcohol or aldehyde, and expelling the viscose at a salt point comprised between 5 and 18, into an acid coagulating bath and aqueous containing sulfuric acid in a percentage of 0.8 to 1.5 times the percentage of caustic soda in the viscose, and 3 to 20%, of zinc sulfate, to form filaments.
