Abstract:In order to improve the dyeing rate and dyeing amount of viscose fiber, auxiliars such as Suzhou Ajer CA, Changzhou Meisheng GRE and RS,and Beijing Qianyan polyacrylamide were used to finish viscose fiber, and the process flows of pre spinning injection, post finishing, and dyeing tank treatment were discussed respectively, the best process was the post-finishing method, the related parameters of sodium hydroxide was 1 0 g/L, Changzhou Meiseng GRE modifier was 15 g/L, the temperature was 100 ℃, and the holding time was 50 min.Compared with ordinary viscose fibers, the treated viscose fibers have strong dye adsorption capacity,the dyeing amount of dye is increased and the dyeing time is shortened, and the rubbing fastness and washing fastness of the dyed fibers are good, both of which can meet the national standards.
