Conventional textile dyeing industries use small molecular weight organic dyestuffs, where the unreacted dyestuff molecules generate large quantities of refractory wastewater and cause serious problems to the environment. This highlight reports on the latest article for textile dyeing through the radiation-induced graft polymerization (RIGP) method, where carbon-carbon double bond functionalized nanoparticles including carbon black, cobalt blue, cobalt green, and iron red were immobilized on the surface of cotton fabric. The wastewater generated in this process can be discharged directly, as the concentrations of the contaminants are lower than those of the international standard and Chinese national standard requirements. The fastness of the color is ensured by the covalent bonding between the nanoparticles and the cellulose macromolecules, which remains unchanged after 100 domestic laundering cycles.

Key words: Radiation-initiated graft polymerization, Green dyeing, Nanoparticles
