Abstract

Process for the manufacture of artificial yarns of regenerated cellulose by extrusion of a viscose, containing one or more compounds that give yarns of filmic structure, in a spinning bath containing sulfuric acid and salts, and drawing of the yarns thus obtained, characterized in which a viscose that has: A) a cellulose content of 4.1 to 6.0% by weight B) a viscosity (measured by the ball drop method) of 100 to 200 seconds C) a range of 45 to 55 D) the ratio between the total alkali content of the viscose and the cellulose content is between 0.6 and 0.75 E) and in which the degree of polymerization of cellulose is from 500 to 800 F) is extruded in a spin bath whose temperature is 20 to 60º c, at a speed that is one and one-half to three times the speed at which the newly spun yarns are drawn from the spinneret G) the spin bath contains from 7 to 13 by weight of sodium sulfate, from 3 to 10% by weight of zinc sulfate and from 1 to 6% by weight of magnesium sulfate and H) the sulfuric acid content of the spin bath is 0.72 to 0.95 times the total alkali content of the viscose.
