Formaldehyde-free Fixative HF-6 belongs to cationic multicomponent polymer, which can form insoluble water lake with anionic groups of reactive dyes, have good binding force with cellulose fibers, prevent the falling off of dyes, and have good blister fastness while ensuring water washing fastness.
Characteristics and advantages: 1. It does not contain free formaldehyde or combined formaldehyde. 2. The hand feel of the fabric has no obvious change after color fixing treatment. 3. After color fixing treatment, the water washing fastness and hot water bubble fastness of reactive dyed and printed fabrics have been significantly improved
