基于天然抗菌剂的涤麻鞋材整理工艺与性能研究

Study on finishing technology and properties of polyester ramie shoe material treated with natural antibacterial agent

以中草药黄芩的提取物黄芩甙为抗菌剂、以涤麻织物为基材,通过浸轧工艺制备出抗细菌/真菌鞋材。优化后的整理工艺条件为:整理液pH值为4.5,整理液浓度2 g/L,浸渍温度55℃,焙烘温度95℃,焙烘时间6 min。整理后的抗菌涤麻织物对大肠杆菌、金黄色葡萄球菌、红色毛癣菌和白色念珠菌的抑菌率均在90%以上,达到国家技术标准QB/T 2881-2013《鞋类和部件抗菌性能技术条件》中所规定的评价标准,同时,织物的相关物性有所改变。

To prepare antibacterial and antifungal shoe material,baicalin,extracted from Chinese herbal medicine Scutellaria baicalensis,was used to finish polyester ramie by padding process.The optimized finishing process conditions are as follows:the pH of finishing solution of 4.5,the concentration of finishing solution of 2 g/L,the soaking temperature of 55℃,the baking temperature of 95℃,and the baking time of 6 minutes.The bacteriostatic rate of finished fabrics exceedes 90%against Escherichia coli,Staphylococcus aureus,trichoderma gautum and Candida albicans,reaches the national technical standard QB/T 2881-2013"Technical conditions for antimicrobial properties of footwear and components".The physical and mechanical properties of finished fabrics change accordingly.
