摘　　要：研究了不同分子质量壳聚糖盐酸盐和壳聚糖双胍盐酸盐对活性染料染色棉织物固色性能的影响。结果发现,壳聚糖盐酸盐的固色效果与其分子质量有关,高分子质量壳聚糖比低分子质量有更好的固色效果,壳聚糖双胍盐酸盐由于引入了更多的阳电荷和亚氨基,增强了壳聚糖双胍盐、染料和纤维分子之间的相互作用。因此,经过壳聚糖双胍盐固色后的棉织物,其皂洗、汗渍和摩擦牢度提高了0.5～1级,湿摩擦牢度改善更为明显。通过红外光谱分析,壳聚糖双胍盐酸盐与纤维和染料之间形成了交联。The fixing performance of chitosan hydrochloride（CSH） with different molecular weight and chitosan biguanide hydrochloride（CSGH） as a fixing agent for cotton fabric dyed with reactive dyes was discussed. The results showed that the fixing effects of CSH on reactive dyes were related to its molecular weight, and the CSH with high molecular weight（HMW） exhibited better fixing effects than that with low molecular weight（LMW）. The CSGH molecule has positive charges and the imino groups, which could further strengthened the interaction among the CSGH, dyes and cellulose molecules. After treated by the CSGH, the soaping, perspiration and dry rubbing fastness of the dyed fabrics could be increased 0.5～1 grade, while the wet rubbing fastness of ones was also improved obviously. The infrared spectrum（FTIR） of the dyed fabric treated by CSGH showed that a cross-linking was formed among CSGH, dyes and cellulose molecules.
