Improvement of Dyeing and Weighting Properties of Silk Via Grafting with Acrylic (AA) and Glycidyl Methacrylate (GMA)

Copolymerization of acrylic acid (AA) and /or glycidyl methacrylate (GMA) with silk was carried out using H2O2/Cu2+reduced system. The results revealed that increasing H2O2 concentrations enhance polymerization up to 0.078 meq/l and also decreased the (TC) and (GY). Presences of Cu+2 ions up to 5 mmol/l accelerate the polymerization of (GY), (GE) and (TC). Increasing GMA and AA concentrations within the range studied were accompanied by enhancing (GY) in contrast with the (HP), (GY), (TC), and (GE) while the (HP) decrease. Crease recovery angle increased from 233o to 324o in the dry state. Dyeability as well as weighting and moisture regain properties were also improved.
