Abstract

Process for manufacturing artificial cellulose yarns from viscose, in which the viscose, which contains at least one compound that gives rise to yarns of film structure, is spun in a spin bath containing sulfuric acid and salts and the yarns newly formed are stretched, characterized in that the viscose that has: A) - a cellulose content of 7 to 9% by weight: B) - a total alkali content of 4.5 to 8% by weight; C) - a viscosity (ball drop method) of 100 to 250 seconds; D) - a gamma number from 42 to 47, and E) - a hottenroth index of maturity from 8 to 13, is spun in a spin bath having a temperature of 45 to 60 and contains 3.8 to 8.5 wt.% sulfuric acid, from 1 to 6% by weight of magnesium sulfate, from 4 to 8% by weight of zinc sulphate and from 7 to 14% by weight of sodium sulfate, the content of sodium sulfate and magnesium sulphate being 11 to 15% by weight.
