Improvement in the process for the manufacture of viscose rayon fibers and yarns, in which a viscose containing quinoline is spun in a spin bath containing sulfuric acid, and the ratio of the weight percent of cellulose to alkali in the viscose is at least 1.3, and the weight percent of quinoline is not less than 0.05 nor greater than 0.25, while in the spin bath, the weight ratio of sulfuric acid is 1, 05-1.15 times greater than that of alkali in the viscose, and the sulfate content of five amounts to not less than 3% by weight, according to the main patent whose improvement consists in that the spinning process is carried out in the presence of one or more surface active substances.
