Description

一种防银纤维变色的复合方法
技术领域
本发明属银纤维的防变色领域,特别涉及一种防银纤维变色的复合方法。
背景技术
银纤维目前主要应用于防辐射服装,其不仅具有防辐射功能,而且具有抗菌杀毒的作用。然而,银纤维在大气环境中二氧化硫和硫化氢等腐蚀性介质的作用下,很快会使银层表面生成浅黄色、黄褐色、甚至黑褐色的硫化银及其溶度积薄膜,在紫外光照射等环境下变色程度就更加迅速和严重。银表面颜色由银白色→浅黄色→褐色→黑色,变色使银的装饰性和银纤维的服用性能大大降低;更重要的是变色使镀银表面电阻增加(约增加20%~80%),使银的电气性能和接触电阻增加,从而大大降低了银纤维织物的电磁屏蔽性能、抗菌杀毒性能以及服用性能。
目前银纤维的防变色方法主要是在银纤维表面形成防变色层,防变色层主要是钛、金、铂、钯等金属,但上述金属昂贵,工艺复杂。银纤维在使用过程中由于受张力,在张力的部位更容易变色。
发明内容
本发明所要解决的技术问题是提供一种防银纤维变色的复合方法,本发明工艺简单易操作,不仅能防止银纤维硫化变色和防止银纤维紫外变色,而且能针对银纤维在使用过程中易受张力的特点防止银纤维变色,耐洗涤性好,具有良好的应用前景。
本发明的一种防银纤维变色的复合方法,包括:
(1)将具有自组装功能的十六烷基硫醇按1-3g∶40-80ml于20-50℃溶于异丙醇中;
(2)将PMTA按0.1-0.3g∶30-80ml于室温溶于无水乙醇中;
(3)将银纤维分别在PMTA溶液和硫醇溶液中外加10mT-25mT的磁场处理40-80min,处理温度为25-50℃,防止银纤维变色。
有益效果
本发明工艺简单易操作,防护材料易得,可回收重复利用;不仅能防止银纤维硫化变色和防止银纤维紫外变色,而且能针对银纤维在使用过程中易受张力的特点防止银纤维变色,耐洗涤性好,具有良好的应用前景。
