Abstract The aim of this work is to determine the dyeing process of the cationic modified viscose fiber. The results indicated that cationic modified viscose fiber greatly improved the dyeing ability and dyeing rate. Sodium chloride and urea have little effect on the dyeing process. The degree of fiber dyeing gradually increased with the dyeing time increasing. The dyeing temperature and fixing time has little effect on the cationic modified viscose fiber. It was also found that the morphology of the viscose fiber had no obvious change after cation modification. The dyeing process had no influence on the mechanical property.
