Grafting copolymerization of silk fibre was carried out with methylmethacrylate (MMA), ethylmethacrylate (EMA) and methacrylonitrile (MAN) in aqueous media using H2O2-Na2S2O3 as redox initiator. To make the graft copolymerization more efficient and economic, the optimum conditions for graft copolymerization were established. The optimum conditions e.g., monomer concentration, initiator concentration and time for MMA, EMA and MAN were 50.0, 0.2 and 90%, respectively and the temperature was 80°C for MMA and MAN and 90°C for EMA. The grafting percentages at optimum condition for MMA, EMA and MAN were 54.34.94 and 19.87%, respectively. The loss in tenacity of non-modified silk fibre was higher (53.87%) than the modified silk (34-35%) after 300 h exposure in sunlight in open air. The modified fibre also showed better lustrous and softness than the non-modified silk. |
