Reactive dye-fiber fixation:-
In practice, fiber fixation predominates due to important factors. Firstly, cellulose has a higher dissociation constant than water, resulting in approximately a 25-fold excess of cellulosate ions over hydroxyl ions. Secondly, the affinity of the dye for the fiber reduces the amount of dye available for hydrolysis in the dyebath. Thirdly, the pH within the fiber is primarily maintained by cellulosate ions and the charge on the fiber surface expels hydroxide ions from the biber interior.
