Mechanism of Action
Color fix mechanism: Acid Fixing Agent HT-2501 forms a layer of complex composite film on the fiber surface, blocking gaps, reducing dye diffusion. At the same time, there is electrostatic repulsion between the anions of the fixing agent and the anions of the acid dye, hindering the diffusion of the acid dye into the dye bath and promoting the diffusion of the dye on the fiber surface into the interior of the fiber, reducing the probability of dissolution.
Water washing color fastness is tested according to ISO 105-C06
