Abstract: Silk fibre has been grafted with poly(congored) (PCR) dye in an aqueous medium under different experimental conditions like temperature, weight of silk fibre and concentration of CR dye in the absence of mordant’s and fixing agents. The grafting kinetics of PCR onto silk fibre is quantitatively followed by spectroscopy (UV-visible and fluorescence spectra) method. The thermodynamic parameters, number of binding sites, binding constant, and nature of quenching system are determined from the kinetic data. The chemical grafting of PCR onto silk fibre is confirmed by FTIR, UV-visible and fluorescence spectra. The conductivity measurements, cyclic voltammetry measurement and FE-SEM analysis also supports the chemical grafting of PCR onto silk fibre.
