摘要
以聚酰胺-胺(PAMAM)树状大分子为载体,硝酸银水溶液为抗菌剂,采用轧-烘-焙后整理工艺对粘胶非织造布进行抗菌整理。优化的粘胶非织造布抗菌整理工艺为:PAMAM树状大分子3%,AgNO3水溶液2.0×10-3mol/L。整理后粘胶非织造布的抗菌耐久性优异,50次水洗后对大肠埃希菌的抑菌率达98%,对金黄色葡萄球菌的抑菌率达97%;断裂强力提高41%,断裂伸长率下降25%,白度下降18%左右。
Antibacterial finish is carried out on viscose nonwovens by padding-drying-curing method with polyamidoamine(PAMAM) dendrimer as carrier and silver nitrate solution as antimicrobial agent.The results show that the optimum antibacterial finish process is treating with 3% PAMAM dendrimer and 2.0×10-3 mol/L silver nitrate solution.The finished viscose nonwovens have durable antibacterial effect with inhibition of Escherichia coli of 98% and Staphylococcus aureus of 97%.The tensile strength of treated fabric improves by 41%,the breaking elongation decreases by 25% and the whiteness reduces by 18%.
