Abstract
本发明是一种长效广谱抗菌织物及其制作方法。本方法是将织物经化学和物理处理，使超细粒的银牢固地附着在织物的纤维上。此种已附有超细粒银的织物，具有显著的抗菌作用，并具有耐高温、耐洗涤，对人无毒、无刺激和无过敏作用，适合皮肤和粘膜的外敷。对金黄色葡萄球菌(青敏和耐药)、绿脓杆菌、淋病奈瑟氏菌、白色念珠菌、白色葡萄球菌、大肠埃希氏菌、阴道毛滴虫和有关病毒有杀灭作用。
Description
本发明是关于一种长效广谱抗菌织物的制造方法，更特别地，是关于一种仅含元素银的抗菌织物的制造方法。
自古以来，我们就知道极微量的金属离子对于微生物和多种细菌有非常强的阻止发育和杀菌效果，铜和银制成的餐具从远古时代就开始被人们使用。
日本《加工技术》VOL.17 NO7报导用Cu2+处理睛纶纤维能阻止金黄色葡球菌和枯草杆菌的发育，从而具有抗菌能力。
中国专利CN87100231公开了一种抗菌防臭纤维织物及其制造方法，具体地在睛纶纤维上分别引入Cu2+和C23H25N2基团，使抗菌能力扩大到金葡球菌、白色葡萄球菌、白色念珠菌、枯草杆菌、大肠杆菌、绿脓杆菌等。
日本专利54-151669公开了一种杀菌性布，包括使用丙烯酸脂橡胶、聚氨酯、醋酸乙酯和银粉(平均粒径6μ)。
但是日本专利的方法均靠树脂溶液的粘着力将银粘附在织物上，在部分的杀菌物料被树脂包覆，仅有露出在树脂表面的少数杀菌物料能起杀菌作用，故其杀菌力是被缩小了，而且织物的柔软性也较差。
本发明的目的是提供一种长效广谱抗菌织物的制造方法。
本发明的第二个目的是提供一种在织物上仅附着有超细粒元素银的织物。
本发明的这些和其它目的将通过下列详细描述来进一步体现和说明。
在本发明中，长效广谱抗菌织物按如下方法来制备：A、将晶体AgNO3(CP级)溶于含氨的水溶液中，得到Ag(NH)2的真溶液；B、在上述制得的Ag(NH)2真溶液中加入葡萄糖并搅匀，立即将织物在室温下，有通风条件下进行浸泡、挤压、浸泡、挤压使之均匀湿润；C、将上述所得织物，在通风条件下用电熨斗高温熨烫，至织物出现褐黑色和黄褐色表面；D、将上述所得织物，放入水中挤压、浸泡、再烫平。
优选地，本发明的产品可以按如下方法来制备：A、将20克晶体AgNO3(CP级)溶于500毫升水和50-100毫升氨水中，溶解后加水稀释至1000毫升，摇匀得到Ag(NH)2的真溶液；B、在上述制得的Ag(NH)2真溶液中加入20毫升25％葡萄糖并搅匀，立即将织物在室温[10-35℃]下，有通风条件下进行浸泡、挤压、浸泡、挤压使之均匀湿润；C、将上述所得织物，在通风条件下用电熨斗高温熨烫，至织物出现褐黑色和黄褐色表面；D、将上述所得织物，放入水中挤压、浸泡、再烫平。
其中，可以使用熨烫机来代替电熨斗。用上述方法所制得的织物上仅附着有超细粒元素银。
在本发明中，本发明是通过化学和物理的处理而制得能牢固附着在织物纤维上的超细粒的元素银。1克超细粒银的表面积可达x00-x000M2从而达到了用极少量的银而能得到很大的具有灭菌能力的银表面。由于银是超细粒状态，所以也强化了银原有的灭菌能力。据申请人认为，可能的抗菌机理如下：
(当Ag呈超细粒状态，表面积
Ag＝Ag+＋e
增大，则利于右向反应。)
Ag+能与菌体中酶蛋白的巯基(-SH)结合，使一些以此为必要基的酶丧失活性，而达到灭菌作用。
由于上述银的抗菌机理，使本发明的附有超细粒元素银的长效广谱抗菌织物具有更强的抗菌能力。尤其对妇女多种阴道炎的主要病原菌，如白色念珠菌、阴道毛滴虫、淋病奈瑟氏菌、绿脓杆菌等具有明显的抗菌优势，对烧伤、外伤病人的皮肤感染，主要病原菌如绿脓杆菌、金葡球菌等具有很强的抗菌作用。
和现有技术相比，本发明具有以下优点：
1.具有广谱抗菌能力(见表1)，尤其是对比现有技术，本发明对绿脓杆菌、淋病奈瑟氏菌、变形杆菌、大肠杆菌、白色葡萄球菌、真菌(霉菌)、阴道毛滴虫具有明显的抗菌优势。
2.本发明对人体无毒性、无刺激、无过敏作用。
3.本发明耐洗性好，经100次肥皂洗涤，1000次以上搓磨，抗菌力无明显减弱。
4.因本发明是超细粒的元素银附着在织物纤维上，因此可以耐高温高压的灭菌操作，利于最终产品的灭菌工序。
5.因本发明是超细粒的元素银附着在织物纤维上，因此可以耐日光曝晒及紫外光照射，不会产生裂解、质变。
6.工艺流程简单、投资小、成本低，且投产快。
