摘要

The graft copolymerization of acrylonitrile monomer onto okra bast fibre has been carried out using potassium persulphate as an initiator in the presence of ferrous sulphate. The graft yield is evaluated on varying the concentration of monomer from 1.0×10~(-2) to 7.0×10~(-2) mol L~(-1) and concentration of potassium persulphate from 1.0×10~(-3) to 7.0×10~(-3) mol L~(-1) at ferrous sulphate concentration varying from 1.0×10~(-3) to 7.0×10~(-3) mol L~(-1) in the reaction mixture. The graft yield and other grafting parameters have been optimized at 3.0×10~(-2) mol L~(-1) monomer, 4.0×10~(-3) mol L~(-1) potassium persulphate, 5.0×10~(-3) mol L~(-1) ferrous sulfate, 120 min treatment time and 70℃ temperature. The composition of grafted chain is characterized by Fourier transform infrared spectra and scanning electron microscopic studies. Dyeing and tensile properties of grafted okra bast fibre have also been studied. The grafted fibre shows better properties in all cases in comparison to bleached okra bast fibre.
