Reactive Dye Fixing Agent
CAS Number: 68555-36-2
Reactive dye fixing agent is a cationic polymer that forms ionic bonds with unfixed reactive dye molecules on cellulosic fibers, significantly improving wet fastness, wash fastness, and perspiration fastness of dyed fabrics. It reduces hydrolyzed dye migration without causing shade change or bronzing effect. Suitable for padding and exhaust application after reactive dyeing.
