Process for manufacturing viscose yarns, fibers and the like, in which starting from a viscose containing oxygenated amines in solution, which is spun in an acid bath with more than 3% by weight of a zinc salt, and the formed yarns are stretched; characterized in that the viscose contains in solution one or several nitrogenous ethers, obtained by reaction between amines and epoxyalkanes, at a rate of 4 molecules of epoxyalkane at least, by 1 amino group and this viscose is spun in a spin bath whose acidity has been adjusted so that the ratio between bath acid and viscose alkali ranges between 1.3 and 0.8.
