  Silk fibers and fabrics pretreated with a silane coupling agent including mercapto group were grafted with dimethylaminoethyl methacrylate by the redox system. Grafted fibers and fabrics were formed the quaternary ammonium compound with methyl iodide in the solution of acetone or the mixed solution of isopropyl alcohol and water. The values of add-on for polymer up-take ratio after treatment reached about 5%, and showed the anti-bacterial effect. For the system of quaternarized at the monomer, the values of add-on tended smaller than that of the system for the former. Iodine atoms in the silk fiber were analysed by using an energy dispersive x-ray analysis system. the peaks of iodine were obviously detected in the former system. The mechanical properties for grafted silk were measured, the changes of them were slightly. The dyeability for grafted silk tended to be easy and darkness because of the cationic character of the monomer.
