芦荟纳米银处理对真丝织物抗菌性能的影响

Effects of aloe nano-silver on the antibacterial performances of silk fabrics

采用生物还原法制备纳米银,利用自制的芦荟纳米银溶液对真丝织物进行功能性整理,研究了银氨浓度、浸渍温度和浸渍时间对真丝织物抗菌性能的影响。以整理织物的ICP和抑菌率为指标,通过单因素实验,确定芦荟纳米银溶液整理真丝织物的较优工艺条件为:银氨溶液浓度0.005 mol/L,浸渍温度40℃,浸渍时间60 min。整理后真丝织物的抗菌性能提高。

Nano-silver was synthesized via a biological method.The silk fabrics were treated with aloe nano-silver solutions.Factors of the concentration of silver ammonia solution,the dipping temperature and the dipping time were studied which affected the antibacterial performances of silk fabrics.The optimal processing parameter was investigated by means of one-factor experiments using ICP and the antibacterial rate as indexes.The optimal concentration of silver ammonia solution was 0.005 mol/L,the optimal dipping temperature was 40 ℃,and the optimal dipping time was 60 min.The treated silk fabrics had good antibacterial performances.
