Abstract:

Acrylic acid (AA) monomers were grafted onto polyester fabric by electron beam irradiation to improve the hydrophilic properties. The optimized reaction conditions were as follows: absorbed dose of 195 kGy, AA concentration of 50%, inhibitor concentration of 0.8%, absorbed dose of pre-irradiation process of 43 kGy, and sodium hydroxide concentration of 15 g/L. The Fourier transform infrared spectrometer spectra showed that AA was grafted onto polyester fabric successfully. The (SEM) showed that the surface of the modified polyester fabric was covered with the film of the grafted polymer. Further, the area of film increased with the grafting rate significantly. The moisture regain of polymer fiber increased with the grafting rate according to the test of moisture regain. The moisture regain of grafted fabric reaches 3.51% when the maximum grafting rate is 27.84%. The fabric still has good hydrophilicity after 30 washing cycles with only 1% of weight loss.

Key words: Polyester fabric, Acrylic acid, Electron beam irradiation, Grafting percentage, Hydrophilicity
