Process for manufacturing viscose rayon fibers and yarns, wherein a viscose containing quinoline is spun in a spin bath containing sulfuric acid; characterized in that, in the viscose, the ratio between the weight percent cellulose and alkali is at least 1.3 and the percentage of quinoline amounts to not less than 0.05 nor more than 0.25, and because in the spin bath, the weight percentage of sulfuric acid is 1.05-1.15 times greater than that of the alkali in the viscose, and the zinc sulfate content amounts to at least 3% by weight.
