纳米银的制备及其对涤纶织物抗菌整理

为了实现涤纶织物的抗菌功能化改性目标，本文以自制的端氨基超支化聚合物（HBP-NH2）为还原剂制备纳米银，利用制得的纳米银溶液对涤纶织物进行抗菌整理，采用扫描电镜观察抗菌织物的纤维表面形态；测定了整理织物的抗菌效率、白度及耐洗性。试验结果表明，制得的纳米银平均粒径在20nm以内，稳定性能良好。当织物上银含量为125.412mg/kg时，对金黄色葡萄球菌和大肠杆菌的抑菌率分别达99.42%和99.27%；洗涤50次后，对金黄色葡萄球菌和大肠杆菌的抑菌率仍保持在98.32%以上，整理效果的耐洗性较好。

Preparation of nano silver and its anti-bacterial finish of polyester fabrics

In order to achieve the goal of antibacterial functional modification of polyester fabrics,the homemade amino-terminated hyperbranched polymer was applied as a reducing agent to produce nano silver.A suitable finishing process was proposed to treat polyester fabrics with nano silver solutions.The fiber surface of the treated polyester was observed by SEM.The antibacterial efficacy,whiteness and washing durability of the treated fabrics were determined.The results showed that the average diameter of nano sil...
