Improvements introduced in a process for the manufacture of fibers, yarn, daughters, films and similar products by spinning viscose in acid spinning baths, preferably spinning baths containing sulfuric acid, in which process a viscose containing organic substances is used. They are soluble in viscose and form temporarily stable zinc chelates with the zinc of the spinning product, said viscose is spun in a spin bath containing zinc and the freshly spun products are characterized in that the viscose is spun in the presence of a substance with surface activity.
