The radiation‐induced graft polymerisation of hydroxyethyl methacrylate on silk fabric has been studied using an electron beam irradiation technique. Two irradiation processes, pre‐irradiation and coirradiation, were compared, and some factors affecting the degree of grafting were investigated. The physical and mechanical properties such as whiteness, breaking strength and resilience of the radiation‐grafted silk fabrics were examined. The hydroxyethyl methacrylate grafting of silk with electron beam irradiation increases silk weight and improves the crease resistance of silk. Electron spin resonance technique shows the formation of free radical species on the electron beam irradiated silk and the rapid decay of radicals in water.
