摘要
为赋予医用棉织物抗菌性,先对棉织物进行醚化改性,然后用黄连活性成分对改性棉织物进行处理。研究表明:棉织物先用浓碱处理后,在35%乙醇溶液中,用150 g/L醚化剂氯乙酸钠进行改性,然后用黄连活性成分上染改性棉织物。小檗碱染色的改性棉织物耐皂洗和耐摩擦色牢度满足纺织品色牢度要求,对大肠艾希菌和金黄葡萄球菌均有优异的抗菌性,且还具有优异的抗紫外线性能。
In order to impart medical cotton fabrics with antibacterial properties,the cotton fabrics are modified by etherification and dyed with the active ingredients of coptis chinensis.The experimental results show that the cotton fibers are etherified with 150 g/L sodium chloroacetate in 35%ethanol solution after treated with con⁃centrated alkali.The modified cotton is dyed with active ingredients of coptis chinensis.The color fastness to soaping and rubbing of the dyed cotton fabric can meet the technical requirements of textiles,and the ones have excellent antibacterial properties against both E.coli and S.aureus,as well as good UV resistance.
