摘　　要：利用具有三维网络结构的改性端氨基超支化聚合物(MHBP-NH2)在水溶液中制备了纳米银,由于MHBP-NH2对纳米银具有调控性,通过其在真丝织物中原位控制生成纳米银,以实现对真丝织物长效抗菌整理。结果表明:由于MHBP-NH2的分子网络结构对纳米银的生成控制和保护作用,所制备的纳米银平均粒径为4.34 nm,且具有优异的稳定性。原位生成纳米银整理真丝织物能够在真丝纤维表面形成均匀分布的纳米银颗粒,该真丝织物具有优异的抗菌性能和耐洗色牢度。当银离子摩尔浓度仅为0.05 mmol/L时,整理后的真丝织物对金黄色葡萄球菌和大肠杆菌的抑菌率就分别达到了99.87%和99.52%,30次洗涤后仍能保持98%以上的抑菌率。This paper prepares nano-silver in aqueous solution through modified amino-terminated hyperbranched polymer （MHBP-NH2） with three-dimensional network structure. Since MHBP-NH2 can control nano-silver, this paper in-situ fabricates nano-silver in silk fabric through MHBP-NH2 to achieve lasting antibacterial finishing. The results indicate that since molecular network structure of MHBP-NH2 has generation control and protection effect on nano-silver, average grain diameter of nano-silver prepared is 4.34 nm with excellent stability. Silk fabric finishing with in-situ generated nao-silve can form even-distributed nano-silver particles on the surface of silk fiber. The silk fabric shows outstanding antibacterial performance and color fastness to washing. When molar concentration of Ag ＋ is 0.05 mmol/L, the antibacterial rate of silk fabric finished on staphylococcus aureus and eseheriehia eoli reaches 99.87% and 99.52% respectively. After washing for 30 times, antibacterial rate can still keep over 98%.
