1、芦荟/纳米银对真丝（绸）的功能化改性研究中文提要本论文采用天然植物芦荟对真丝绸进行功能化改性，以提高真丝绸织物的防紫外性能和抗菌性能，同时不损伤真丝绸原有的优异服用性能，为采用天然植物提取物对纺织面料进行功能化性整理研究提供了理论依据。论文首先对芦荟进行了超声波提取，得到了芦荟的乙醇提取物，并得出了其主要成分为蒽醌类物质的结论。探讨并得到了较优的提取工艺条件。采用芦荟乙醇提取物对真丝绸织物进行整理，实验表明整理后的丝织物有良好的抑菌作用，在UVA、UVB 波段透过率大幅度下降，对紫外线有着很好的屏蔽效果。在芦荟乙醇提取物浓度为 8g/L 时，织物的 UPF 值为 66，对金黄色葡萄球菌和大肠杆
2、菌的抑菌率分别为 79.6%和 77%。论文进一步对芦荟进行了水浸提取，在常温下与 AgNO3溶液反应制得了芦荟纳米银胶体溶液，对纳米银的粒径进行了表征并测试了制备的芦荟纳米银胶体溶液的抗菌性能。采用芦荟纳米银胶体溶液对真丝绸进行整理，进一步提高了真丝绸的抗菌性能，整理后真丝绸对金黄色葡萄球菌和大肠杆菌的抑菌率分别达到 99.5%和99.7%。关键词：关键词：真丝绸；芦荟；纳米银；抗紫外；抗菌性作 者：韩艳梅指导教师：陈宇岳Functional Modification of Silk Fabric Treated with Aloe / nano-silverAbstractThis the
