Finally, the grafting polymerization of textile materials initiated by microwave low temperature plasma was conducted. Knitted cotton fabric was grafted by AMPS first, then knitted cotton and terylene/cotton fabrics were grafted with AMPS/NIPA dualistic monomers respectively. By means of grafting polymerization, the P dualisticintelligent hydrogel was added to textile.The influences of the factors on add-on, such as treatment time and power of plasma, concentrations of crosslinking agent and total monomers, proportion of AMPS, polymerizing temperature and time etc, was studied fully. The optimal conditions of grafting polymerization initiated by microwave low temperature plasma were determined by orthogonal design, variance analysis and mathematical statistics method so as to analyze the main influencing factors. Then swelling/deswelling kinetics, temperature-sensitivity and pH-sensitivity of grafted textile were studied. The performance indexes of hydrostatic pressure, moisture permeability and bursting strength of the knitted cotton and terylene/cotton fabrics before and after grafting were compared and evaluated synthetically.
