Abstract
Linear electron beam radiation has been used to induce irradiation grafting of glycidyl methacrylate (GMA), glycidyl methacrylate/β-cyclodextrin (GMA/β-CD), and glycidyl methacrylate/monochlorotriazinyl-β-cyclodextrin (GMA/MCT-β-CD) onto cotton fabrics. The effect of radiation dose, GMA concentration and CDs concentration on graft yield, epoxide content and the bonded amount of CDs was investigated. Results obtained reveal that the amount of CDs bonded within the fabric; the add-on and the epoxide content are directly related to the CDs concentration, GMA concentration and the irradiation dose. Graft yield and epoxide content increase with the increase of radiation dose to a certain extent, and they decrease due to degradation of GMA at higher irradiation doses. Results also reveal that although the bonded amount of CDs is nearly proportional to the concentration of CDs in the treatment solution, the accessibility ratio of CDs decreases with increasing CDs concentration. Treatment of fabrics grafted with GMA (Cell-g-GMA) and GMA/CDs mixtures (Cell-g-GMA/CDs) in a sequel step with the corresponding CDs increases the amounts of CDs fixed onto the fabrics, while epoxide content decreases. The treatment of the cotton fabrics with GMA and CDs was established on the basis of spectral data studies.
