纳米银涤纶面料的抗菌性能

以白念珠菌抑菌率为评价指标,研究染整加工对纳米银涤纶纤维面料抗菌性能的影响。优化的染整工艺为:纳米银涤纶面料先采用0.5%除油剂于110℃前处理20 min,再于190℃定形40～50 s,然后于130℃染色30 min,140℃成品定形30～40 s。高温和碱性还原处理会降低纤维的抑菌性能。染整加工后,纳米银涤纶仍然具有一定的抑菌性能。洗涤20次后,混纺纳米银涤纶纤维面料也可保持较高的抑菌性能。

Anti-bacterial property of CLEANCOOL

Dyeing and finishing process of polyester fabric built-in nano silver(CLEANCOOL) is carried out.Effect of process conditions on anti-bacterial property is studied with antibacterial inhibition of Candida albicans as the evaluation index.The optimum process conditions are pretreating with 0.5%oil removal agent at 110℃for 20 min,pre-setting at 190℃for 40～50 s, dyeing at 130℃for 30 min,and then setting at 140℃for 30～40 s.The anti-bacterial property of polyester fiber decreases under high temperature or alkali reduction conditions,but still remains good when treated with selected treating process.The polyester fabric built-in nano silver has satisfactory anti-bacterial property even after 20 launderings.
