CELLULOSIC FIBER DYEABLE WITH A CATIONIC DYE AND ITS WOVEN OR KNITTED FABRIC

摘要

PROBLEM TO BE SOLVED: To obtain cellulosic fiber dyeable with a a cationic dye which develops dyeing having resistance to wet-heat treatment even in a processing process adopting the wet-heat treatment. SOLUTION: The cellulosic fiber dyeable with the cationic dye contains 1-30 wt.% of a sulfonate group-containing surfactant which has <10% eluted amount from the fiber based on the amount of the surfactant added in a wet-heat treatment at 120-135°C for 30 minutes.
