Graft polymerization of acrylonitrile onto chemically modified bleached jute fibers

The graft polymerization of acrylonitrile (AN) onto chemically modified bleached jute fibers has been studied using potassium peroxydisulfate‐ferrous ammonium sulfate redox initiating system. The effects of time of reaction, variation in concentration of monomer, peroxydisulfate, ferrous ammonium sulfate and sulfuric acid on graft yield have been studied. The effects of temperature, amount of jute fibers, some inorganic salts and organic solvents on graft yield have also been investigated. Grafted jute has been characterized by IR spectra. Grafting has improved the light fastness of jute dyed with Rhodamine B dye.
