A study of the graft copolymerization of methyl methacrylate onto jute fiber, using K 2 S 2 O 8 ‐thiourea (TU) redox‐initiating system has been made. The effects of concentration of monomer, S 2 O 8 2− , TU on graft yield have been studied. Besides the effects of time, temperature, acid, and amount of jute fiber, some inorganic salts and organic solvents on graft yield have been investigated. The most remarkable features of the investigation include proposition of a mechanism for the grafting process and characterization of grafted fiber by infrared (IR) and thermogravimetric studies. Grafting has improved the light fastness of jute fibers dyed with basic dyes. More than 200% graft yield could be achieved in the present investigation.
