A process for the manufacture of regenerated cellulose yarns, fibers and films, by spinning viscose in a bath containing sulfuric acid, sodium sulfate and at least 30 g/kg of zinc sulfate, and drawn in a second hot bath, characterized by adding to the viscose 1-5 g/kg of a mixture consisting of 15-50% polyglycols and 85-50% alkoxylated amines of the following formula **(See formula)** where R1 and R2 signify alcoholic oxide chains of the formula - (CnH2n =) xH where x and n can be different for R1 and R2, while the sum of x for R1 and R2 is at least 5; and where R3 is hydrogen, an alcoholic oxide chain, an alcohol radical, a cyclic or heterocyclic radical, or an N-containing group of the formula **(See formula)** where X represents an aliphatic, aromatic, or cycloaliphatic radical, and R4 and R5 can be hydrogen, alcoholic oxide chains, or aliphatic, cyclic, or heterocyclic radicals.
