Abstract
Cationic cellulose graft copolymers obtained by the graft polymerization of a cellulose substrate and a cationic monomer are useful as textile treatment agents, especially as dye enchancers. As pretreatment agents, they improve dye yield, dye levelness and dye fastness properties and as after-treatment agents, they improve dye fastness and crock resistance properties.
