摘要：

为了提高纳米银在织物上的施加量并减少纳米银团聚，采用马来酸酐改性超支化聚合物为模板配制硝酸银/改性超支化聚合物整理液，通过浸渍-汽蒸整理工艺制备纳米银棉织物。研究硝酸银/改性超支化聚合物质量配比对纳米银粒径的影响，探讨了整理液浓度和汽蒸条件对棉织物整理效果影响，考察整理织物耐洗性，并将该工艺与其它整理工艺比较。结果表明：硝酸银/改性超支化聚合物最佳质量配比为0.17：2；当汽蒸时间为45min，硝酸银浓度为0.085g/L时，整理织物的抑菌率已达99.99%；经50次标准洗涤后整理织物抑菌率仍大于94%；相对于棉自还原法和丁二酸酐改性超支化聚合物模板法，马来酸酐改性超支化聚合物模板法整理织物银含量高，且有效改善了纳米银团聚。

Abstract:

In order to improve the amount of nano-silver on the fabric and reduce the aggregation of nano-silver , maleic anhydride modified hyperbranched polymers was applied as template for preparing silver nitrate /modified hyperbranched polymer finishing liquor, and through dipping the cotton fabric in the liquor and steaming for silver ion reduction, the nano-silver finished cotton fabric was prepared. The influence of the mass ratio of silver nitrate /modified hyperbranched polymer on the particle size of nano-silver were studied, the finishing liquor concentration and steaming conditions on finishing effects were investigated. The washing resistance of the finished fabric was tested, and the process of maleic anhydride modified hyperbranched polymers as template to prepare nano–silver fabric were compared with other finishing process. The results showed that the best mass ratio of silver nitrate /modified hyperbranched was 0.17 : 2, the optimal steaming time was 45min, when the concentration of silver nitrate was 0.085g/L, the bacterial inhibition rate of the finished fabric reached 99.9%. After 50 wash cycles, the bacterial inhibition rate was over 94%.Compared to finishing processes of cotton finished by reducing silver ions with cotton itself and the method of succinic anhydride modified hyperbranched polymer as template, the silver content of fabrics finished by succinic anhydride modified hyperbranched polymer as template is high and aggregation of nano-silver is improved.
