碱改性羊毛的聚六亚甲基双胍抗菌整理

Antimicrobial finishing of alkali pretreated wool using polyhexamethylene biguanide

分别采用NaOH、NaAlO_(2)、Na_(2)CO_(3)对羊毛织物进行改性,以提高羊毛织物对聚六亚甲基双胍(PHMB)的吸附率。研究表明,分别采用50 mmol/L NaOH、100 mmol/L NaAlO_(2)、100 mmol/L Na_(2)CO_(3)改性的羊毛织能够吸附4.2%、2.5%、2.2%(omf)的PHMB。吸附了PHMB的羊毛织物均能够杀灭99.9%以上的大肠埃希菌。

NaOH,NaAlO_(2) and Na_(2)CO_(3) are used to modify wool fabric to improve the adsorption rate of PHMB.The results show that the wool fabric modified with 50 mmol/L NaOH,100 mmol/L NaAlO_(2) and 100 mmol/L Na_(2)CO_(3) can adsorb PHMB of 4.2%,2.5% and 2.2%(omf).Wool fabrics finished with PHMB exhibit strong antibacterial properties and are able to kill more than 99.9% ofEscherichia coli.
