An improvement in the object of Main Patent No. 237,281, for: "A process for the production of artificial yarns, bands, films and similar products from viscose", in which a viscose, containing 1.0-6, 0% by weight relative to the viscose cellulose of one or more compounds of the formula **(See formula)** wherein R1 is at least preferably one of 6 carbon atoms, alkyl, aryl or alicyclic radical, R2 is 1 to 3 carbon alkyl radical, n represents an integer from 0 to 5, x + y is an integer between 2 and 50 or more, while neither x nor y can be 0, and Z represents an anion that has practically no surface activity, is spun in a spinning bath, containing not more than by weight of sulfuric acid and at least 2% by weight of zinc sulfate, characterized in that a slightly matured viscose, containing at least one of said compounds, preferably in a proportion of 2 to 4% by weight based on the viscose cellulose, it is spun in a spinning bath containing at least 0.04% by weight, preferably however 0.08 to 0.2% by weight of at least one compound of the formula **(See formula)** where R3 represents an aliphatic chain with at least 8, and preferably 12 to 24 carbon atoms, n is equal to 2, 3 or 4 and x + and is at least 5, and preferably 12 to 18, while Neither x nor y can be 0.
