摘　　要：合成新型多氨基支化结构水溶性壳聚糖衍生物（cs—HCA）并用于超纤合成革的改性，探讨了其对超细纤维合成革性能影响。抗菌实验结果表明：在pH=6的弱酸性条件下，0．05％质量分数的合成产物对大肠杆菌的抑菌率达99％；染色实验表明：当改性产品的用量达到O．6％～0．8％（以基布质量计）时，上染率达到最大值95．3％；超纤合成革经改性后其透水汽性提高20％；15min的吸水性增加21．5％，24h的吸水性增加25．4％，卫生性能得到了显著提高。A new type of soluble chitosan derivatives （CS-HCA） with multi-branched amino structure were prepared and ap- plied for modification of microfiber synthetic leather.The antibacterial experimental results showed that the inhibition ratio of 0.05% mass fraction of the synthetic product to coli was 99% at pH=6; Dyeing experiment showed that when the usage of CS- HCA is from 0.6 to 0.8% （based on fabric mass）, the absorption ratio of dyestuff reached a maximum value by 95.3%;After modification by CS-HCA,the water vapor permeability of microfiber synthetic leather was increased by 20%; 15min and 24h of water absorption increased by 21.5% and 25.4% respectively, hygienic property was improved significantly.
