High-Function Fibers High Color Development of Polyester Fiber

摘要

Cation-dyeable polyester fiber Since the molecules of polyester fiber have no reactive groups that chemically bond to the dye, it is difficult to dye vividly Cation-dyeable polyester fiber is designed to be dyed vividly by copoly-merizing a compound having an acidic group and forming an ionic bond with the basic group of the cationic dye.
