摘要
以黄芩苷、壳聚糖和海藻酸钠为原料,通过乳化交联法制备了微胶囊,表征了微胶囊的表面形貌、粒径分布、化学成分、热学性能及抗菌性能.采用交联剂整理法分别制备了黄芩苷和黄芩苷微胶囊功能棉织物,对比分析了两种织物的表面形貌及抗菌性能.研究结果表明:微胶囊对大肠埃希菌和金色葡萄球菌的抑菌率均在99％以上;相比于黄芩苷,微胶囊可以更好地黏附在棉织物表面;两种功能织物的抑菌率均大于90％;洗涤后,黄芩苷微胶囊棉织物的抗菌性优于黄芩苷整理棉织物.
Abstract
The microcapsules are prepared by emulsion-chemical cross-linking method with baicalin,chitosan and sodium alginate as raw materials.The surface appearance,particle size,chemical structures,and thermal properties of microcapsules are characterized.Baicalin and baicalin microcapsules are separately finished on cotton fabrics by cross-linking agent finishing method,and the surface appearance and antibacterial properties of the two functional fabrics are analyzed.The results show that the antibacterial rates of microcapsules against E.coli and S.aureus are both above 99％.Compared with baicalin,the microcapsules are better adhered to the surface of cotton fabric.The antibacterial rates of the two functional fabrics are above 90％.The antibacterial activity of baicalin microcapsule cotton fabric is better than that of baicalin treated cotton fabric after washing.
