Improvements in the process for manufacturing viscose artificial fibers and yarns according to patent No. 227,434, in which a viscose added with epoxyalkane polymers is spun at a rate of 0.1 to 1% by weight (calculated on the viscose), in a bath of spinning 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, the alkali content of the viscose, characterized because in addition to the epoxyalkane polymers, one or more compounds of the formula are added to the viscose ** (See formula) ** where R1 is an aliphatic radical with not less than 8 carbon atoms, n is 2, 3 or 4, and x and y can not be zero, or their quaternary ammonium compounds; the amount of the epoxyalkane nitrogen compounds being 15-40% of the sum of the amounts of the epoxyalkane polymer and the epoxyalkane nitrogen compound; and an organic compound that irreversibly binds the sulphide ions of the viscose, and is added immediately before spinning the viscose.
