SYNOPSISPolypropylene fabric was gamma pre-irradiated at doses of 1,2, and 3 Mrads. The irradiated fabric was grafted with an aqueous solution of 2-(dimethylamino) ethyl methacrylate. The graft yield was studied as a function of the different variable conditions such as storage time, monomer concentration ( 10-40%), reaction time, and temperature ( 50, 70,lOO"C). The grafted polypropylene was further quaternized with dimethyl sulphate or monochloroacetic acid. The grafted and quarternized fabrics were dyed with an acid dye. The fixation properties of the dyed samples were determined by DMF extraction. The moisture regain and mechanical properties were also measured.
