Cationic Dye Fixative for Reactive Dye
CAS Number: 26590-05-6
A polyamine-based cationic fixative designed to improve wet fastness and washing fastness of reactive-dyed cotton and viscose fabrics. It forms an ionic complex with unfixed reactive dye anions on the fiber surface, reducing dye bleeding without significantly altering the original shade. Commonly used as an after-treatment in exhaust and continuous dyeing processes.
