  • Effects of pH on Graft Copolymerization of Poly (methacrylamide) on Silk Fibers and Some Properties of The Grafted Silk Fabrics.

抄録

Optimum conditions for graft copolymerization of poly(methacrylamide) on silk fabrics have been observed at a narrow range of pH between 1.2 and 2.8. With grafting of poly(methacrylamide) on silk fibers, shrinkages of cloths were observed and the thickness and the yarn densities of cloths increased. In the low pH regions for the graft copolymerization, tensile strength was maintained and elongation of fiber at break increased, although the fibers used have been damaged. It was considered to be due to the effect of the mutual entanglement of poly(methacrylamide) grafted on fibroin. Bending rigidity of fabrics increased, but abrasion resistance was improved by grafting. Crease resistance decreased by 20% with 60% grafting, and a somewhat increase of crease resistance in water have been observed.
