摘　　要：用过氧化氢在中性条件下氧化降解壳聚糖 ,研究了不同分子量壳聚糖改性的棉织物用活性染料和直接染料的染色 ,测定了各项染色动力学参数 ,壳聚糖改性棉织物对染料的吸附与扩散有不同程度的提高 ,提高程度与壳聚糖分子量、染料种类等密切相关。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.
