摘要
结合壳聚糖季铵盐(HACC)和纳米Ag的优点,采用无机-有机复配方式,制备了新型纳米Ag/HACC复合抗菌整理剂,并将其用于棉织物的抗菌整理。结果表明,经1%HACC+0.1 g/L Ag+0.2 g/L PVP整理后,棉织物经30次洗涤仍能保持80%以上的抑菌率,且具有良好的手感和白度。纳米Ag/HACC复合抗菌整理剂实际是纳米Ag与HACC酰胺基间的分子识别,协同起到杀菌作用。
A novel nano-silver/HACC （2-hydroxypropyltrimethyl ammonium chloride chitosan） composite was prepared by organic-inorganic compounding method, and it was applied to anti-bacterial finish of cotton fabric. Results showed that the cotton fabric treated by the combination of 1% HACC, 0.1 g/L Ag and 0.2 g/L PVP remained 80% bacterial-inhibition even after 30 laundering cycles, and had good handle and whiteness as well. In fact, there is a molecular recognition between nano-silver and amide group of HACC in nano-silver/HACC composite anti-bacterial agent, which generates sterilization effect synergically.
