利用双氧水氧化降解壳聚糖，以2，3-环氧丙基三甲基氯化铵为改性剂，对氧化降解后的低分子量壳聚糖进行季铵化改性，得到壳聚糖季铵盐（HTCC），利用HTCC对大豆蛋白复合纤维改性后进行无盐染色，并与传统染色工艺进行对比分析。红外光谱曲线表明己经有效合成了HTCC；实验结果显示，季铵化改性后可以大大提高壳聚糖的水溶性，取代度达到90%左右；另外发现，HTCC在温度90℃、浓度8 g/L条件下浸渍处理大豆蛋白复合纤维10 min，可获得最佳的预处理效果；经HTCC改性的大豆蛋白复合纤维织物在染色中可以降低盐的用量，且无盐染色织物水洗色牢度与传统染色工艺的相当。

After chitosan degraded by hydrogen peroxide, chitosan quaternary ammonium salt(HTCC) is made with 2,3 epoxypropyl trimethyl ammonium chloride existing, which is used as modifier agent for quaternized modification. Then soybean protein composite fibers are pretreated by HTCC, the dyeing processes without salts of it are ana-lyzed, compared with traditional dyeing process of common soybean protein composite fibers. The results from in-frared spectrum curve proves that HTCC are composed effectively; it is also found that after quaternized modifica-tion, the water-solubility of chitosan are improved obviously and the degree of substitution can reach about 90%. The optimum conditions for soybean protein composite fibers pretreatment by HTCC are: 8 g/L of HTCC treat fibers under 90 ℃ for 10 minutes. The results also show that after soybean protein composite fibers pretreated by HTCC, dosage of salts in dyeing process can be decreased; meanwhile, the washing fastness that dyeing without salts is the same with that of traditional dyeing process.
