A difference in the effect of sodium sulfite additions in a model solution of caustic soda and carbon disulfide and in viscose has been shown in the process of formation of by-product sulfur-containing compounds.
Simultaneously with a retardation of ripening and an increase in homogeneity, the introduction of sodium sulfite into viscose leads to an increase in the elemental sulfur content of the yarn.
