A process for the manufacture of artificial yarns and fibers by spinning viscose in a spinning liquid bath making use of spinning nozzles provided with non-circular orifices, characterized in that the viscose is spun into a spinning bath containing more than 15% by weight of ammonium sulfate, not more than 10% by weight of sodium sulfate, not more than 0.1% by weight of zinc sulphate, and a proportion of sulfuric acid such that the ratio of the percentage by weight of sodium hydroxide contained in the viscose to the weight percentage of sulfuric acid in the spinning bath is between 0.9 and 1.85.
