Improvements in the object of the main patent No. 227,434, issued on March 24, 1956, by "Procedure for the manufacture of viscose artificial fibers and fibers" starting from a viscose to which epoxyalkane polymers have been added in amounts of 0.1 to 1% by weight (calculated on the viscose) and spinning this viscose in a bath containing sulfuric acid with not less than 2% by weight of zinc sulphate, and in which, in proportions by weight, the sulfuric acid content does not exceeds 1.3 times the alkali content of the viscose; characterized in that a viscose is spun containing, in addition to the epoxyalkane polymers, one or more compounds of the general formula, ** (See formula) ** where R1 is an aliphatic chain with not less than 8 C atoms; n, is 2, 3 or 4; and x + y, is 2 at least, without being zero x or y; or their respective quaternary ammonium compounds; and the amount of substituted amines is from 15 to 40% by weight of the total polymer content of epoxyalkane and amine.
