Factors affecting the radiation grafting of diethylaminoethyl methacrylate onto cotton, polyester and polyamide fabrics

摘要

Factors affecting the radiation grafting of diethylaminoethyl methacrylate (DEAEMA) onto cotton, polyester and polyamide fabrics have been studied to obtain optimum conditions that improve the dyeability of Drimalan reactive dye. It is observed that gamma doses of u to 4 Mrad (40 kGy) do not show any noticeable graft yield until benzoyl peroxide catalyst is added. All the fabrics show maximum graft yield at 0.01 /100 benzoyl peroxide, 10/100 monomer (DEAEMA) and 1:15 fabric- to-liquor ratio.
