Improvement in the procedure of the main patent for the manufacture of artificial threads and fibers of viscose, in which a viscose to which polymers, copolymers or block polymers of epoxyalkane or their substitution products are added, in proportions of 0.1 to 1% by weight (calculated on viscose), it is spun in a bath containing sulfuric acid with not less than 2% by weight of zinc sulphate and in which, the sulfuric acid content does not exceed 1.3 times, by weight, of the alkali content of the viscose; whose improvement consists of adding to the viscose epoxyethane polymers with a molecular weight between 3800 and 4200.
