聚醚改性季铵盐有机硅抑菌柔软剂的合成及应用

Synthesis and application of polyether modified quaternary ammonium silicon antibacterial softening agent

将小分子有机硅季铵盐通过共聚合的方式接入聚醚改性的聚二甲基硅氧烷中,合成新型嵌段自乳化的抑菌柔软整理剂,在保证抑菌效果的同时不会有小分子溶出,实现了“接触式”抑菌。整理后织物的物理性能好于普通工艺。织物水洗20次后,对金黄葡萄球菌、大肠杆菌和白念珠菌的抑菌率分别为98%、99%和75%,抑菌效果良好。

In order to ensure the bacteriostatic effect without micromolecules bleeding,the synthesis of selfemulsified antibacterial softening copolymer is carried out by copolymerization,which embedded micromole⁃cule quaternary ammonium compounds into polyether-modified polydimethylsiloxane.The physical property of the finished fabric is better than that with the ordinary process.After washing for 20 times,the finished fabric still features good antibacterial effect with the antibacterial rates to Staphylococcus aureus,Escherichia coli and Candida albicans are 98%,99%and 75%,respectively.
