端氨基超支化合物接枝氧化亚麻纤维抗菌抗紫外性能研究

摘要

HBP-NH2 grafted oxidized linen fiber (HGLF) was prepared by the oxidation of linen fiber with sodium periodate and subsequent grafted with HBP-NH2.The antimicrobial properlies and anti-UV radiation of HGLF was studied.The results indicated that HGLF showed 90.74％ of bacterial reduction to S.aureus and 93.12％ of bacterial reduction to E.coli, respectively.The inhibition rate of HGLF to S.aureus and E.coli were maintained at 90％ even after 20 times consecutive home laundering.The UPF value was increased from 3.44 to 13.19.HGLF owned good antibacterial and anti-UV radiation performance.%亚麻纤维经高碘酸钠选择性氧化后再接枝HBP-NH2,制备了HBP-NH2接枝氧化亚麻纤维(HGLF).研究了HGLF的抗菌和抗紫外性能,结果显示:HGLF对金黄色葡萄球菌和大肠杆菌的抑菌率分别达到了90.74%和93.12%,且经20次洗涤后对金黄色葡萄球菌和大肠杆菌的抑菌率仍保持在90%左右;HGLF的UPF值从3.44提高到13.19,说明HGLF具有良好的抗菌性能和紫外线屏蔽效果.
