摘要: 运用紫外光辐射的方法对超细羊毛纤维表面进行刻蚀、糙化, 并在其表面接枝载银纳米SiO₂ 抗菌剂制备抗菌羊毛纤维。通过SEM、IR 等, 对其物理性能进行了表征; 同时测试了其抗菌和耐洗涤性能。结果表明, 制备的抗菌羊毛纤维表面形成了约200 nm 的抗菌层, 羊毛纤维与纳米抗菌剂以价键形式结合而非单纯的物理吸附,其对大肠杆菌和金黄色葡萄球菌的抗菌率达96 %以上, 经20 次以上洗涤, 抗菌率仍能达到90 %以上。

Abstract: The wool fibers were carved and corroded to get rough surface by using ult raviolet radiation. So the antibacterial wool fibers were prepared by graf ting the nanometer silicon dioxide silver-loaded antibacterial agent . Thephysical , antibacterial and washable properties were characterized by using SEM , IR , etc. The surface layer of 200nm thickness was const ructed , and the nanometer antibacterial agent s are connected with the wool fibers by thechemical bonds. And the nanometer antibacterial agent is not simply attached to the surface by physical adsorption.The antibacterial efficiency of Escherichia col i and S taphy lococcus aureus is up to more than 96 % without washing ,and it is more than 90 % af ter repeated washing (at least 20 times) .
