【Abstract】 The dyeing process of cotton fabrics modified using chitosans with different molecular weights which are prepared by oxidization hydrolysis with peroxide is studied.The dyeing kinetic parameters are determined.Comparing to unmodified cotton fabric,chitosan modification can improve the adsorption and diffusion,and the molecular weight of chitosan and dye types are relative to the improvement of adsorption and diffusion.更多还原
