REGENERATED CELLULOSE FIBER EXCELLENT IN DYEING PROPERTY AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To obtain a regenerated cellulosic fiber excellent in dyeing property to acidic dye and light resistance by adding a polyallylamine (derivative) to viscose and spinning the mixture and coagulation-regenerating, refining and drying the spun yarn. ;SOLUTION: A polyallylamine and/or polyallylamine derivative such as cyanoethylated polyallylamine having 1-100mol% cyanoethylation ratio, preferably in an amount of 0.1-20.0wt.% (based on cellulose) is added to viscose and the mixture is spun and the spun yarn is coagulation-regenerated, refined and dried to provide the objective regenerated cellulose fiber. Furthermore, the degree of polymerization of the polyallylamine (derivative) is preferably ≥10000.;COPYRIGHT: (C)1997,JPO
