摘要/Abstract

摘要： 针对目前棉织物纳米银抗菌整理存在银离子利用率低和耐水洗性差的问题，采用棉织物甲基丙烯酰胺接枝、硝酸银浸渍和汽蒸整理工艺，制备纳米银抗菌整理织物。研究整理工艺因素对硝酸银利用率、整织物纳米银含量以及抗菌性能的影响，考察整理织物的耐洗性。实验结果表明：甲基丙烯酰胺接枝可提高硝酸银利用率和织物纳米银含量，接枝率15.05%时，硝酸银利用率最大，织物纳米银含量最高；硝酸银浓度0.1mM时，整理织物纳米银含量为102.9 mg/kg，大肠杆菌和葡萄球菌抑菌率均达到99.9%，50次洗涤后，银含量保留率为83.19%，两种菌种的抑菌率仍超过97%。研究表明甲基丙烯酰胺接枝、硝酸银浸渍和汽蒸的纳米银整理工艺，银离子利用率高，整理织物具有优异的抗菌及耐洗涤性能。

Abstract: In view of the disadvantages of nano-silver antibacterial finishing on cotton fabric at present such as the low utilization rate of silver ion and poor washing durability, a suitable finishing process which included methacrylamide grafting onto cotton fabric, silver nitrate dipping and steam finishing was used to prepare nano-silver antibacterial finishing fabric. The influence of finishing factors on the utilization rate of silver ion, silver content on fabric and antibacterial property of finished fabric was studied, and the washing resistance of the finished fabric was investigated. The results showed that the process of cotton grafted with methacrylamide could raise the utilization rate of silver nitrate and silver content on fabric, and the utilization rate of silver nitrate and silver content on fabric both reached maximum when the grafting yield was 15.05%; when the concentration of silver nitrate was 0.1mM, the silver content on fabric was 102.9 mg/kg, the bacterial inhibition rate for bacillus coli and staphylococcus aureus both reached 99.9%, after washing 50 times, the retention rate of silver on fabric is 85.19%,the bacterial inhibition rate for these two kinds of bacteria is over 97%. The study indicates finishing process which included methacrylamide grafting onto cotton fabric, silver nitrate dipping and steam finishing had the following advantage, the utilization rate of silver ion was high, and the finished fabric have an excellent antibacterial property and washing resistance.
