Abstract
本发明公开了一种主动广谱持久抗菌抗病毒医用防护服、纺织物及其制备方法，纺织物的制备方法包括：将纳米银溶胶、无机抗菌剂和有机抗菌剂配成一定浓度的溶胶混合液；将非织造材料浸泡于溶胶混合液一段时间；经烘干、压平、收卷即可得到抗菌抗病毒纺织物。主动广谱持久抗菌抗病毒医用防护服，由上述制得的纺织物作为面料制得。将传统的金属离子抗菌抗病毒技术、有机物抗菌抗病毒技术、光触媒抗菌技术三者相结合，在不影响透气性的同时，赋予医用防护服持久有效的广谱的抗菌抗病毒性能，抗菌率达到99%以上，并且对流感病毒（H1N1和H3N2）的速杀效果非常好，抗病毒活性率99%以上，可以水洗循环使用。
Description
技术领域
本发明属于防疫设备技术领域，具体涉及一种主动广谱持久抗菌抗病毒医用防护服、纺织物及其制备方法。
背景技术
目前市面上的医用防护服本身并不能对病毒、细菌等进行消杀，其主要是通过防护服自身的制作标准一方面对水、血液、酒精等液体的渗透，避免在手术过程中病人的血液、体液及其他分泌物等将携带的细菌、病毒传染给医务人员，防止携带的病毒引起医患之间交叉感染；也可以对颗粒物质进行阻隔防止通过空气进行传播的病毒以气溶胶的形式被吸入或附着在皮肤表面被人体吸收。这样一方面当防护服废弃后由于一次性材料降解缓慢容易造成环境污染；另一方面可重复使用型的防护服需经过洗涤、高温消毒等措施才能重复利用，也使得其防护性能通常较差，洗涤、消毒过程也会增加大量的人力成本和浪费水资源。
现有技术存在以下缺陷：传统医用防护服自身不能主动抗菌抗病毒，以及抗菌时间较短。
发明内容
目的：为解决现有技术的不足，本发明提供一种主动广谱持久抗菌抗病毒医用防护服、纺织物及其制备方法，将金属离子抗菌抗病毒技术、有机物抗菌抗病毒技术、光触媒抗菌技术三者相结合，在不影响透气性的同时，赋予医用防护服持久有效的广谱的抗菌抗病毒性能，抗菌率达到99％以上，并且对流感病毒(H1N1和H3N2)的速杀效果非常好，抗病毒活性率99％以上，对皮肤安全无刺激性，防霉等级也达到了0级，而且水洗50次后，防护服的抗菌效果仍在99％以上，因此防护服可以水洗循环使用，大大降低防护服的使用成本，同时也降低了环境污染。
技术方案：为解决上述技术问题，本发明采用的技术方案为：
一种用于医用防护服的纺织物的制备方法，包括：
将纳米银溶胶、无机抗菌剂和有机抗菌剂配成一定浓度的溶胶混合液；
将非织造材料浸泡于溶胶混合液一段时间；
将浸泡过的非织造材料经烘干、压平、收卷即可得到抗菌抗病毒纺织物。
在一些实施例中，所述非织造材料为聚丙烯纺粘布、聚酯纤维与木浆复合的水刺布、聚丙烯纺粘-熔喷-纺粘复合非织造布、高聚物涂层织物、聚乙烯透气膜/非织造布复合布中的一种。
在一些实施例中，所述的纺织物的制备方法，所述的烘干温度为100-110℃之间。
在一些实施例中，所述的纳米银溶胶平均粒径在20-30nm之间。
在一些实施例中，所述的无机抗菌剂为纳米二氧化钛、纳米氧化锌、钨酸铋、纳米二氧化硅、氧化钨、氧化铁、氧化锡、钼酸铋、钛酸锶中的一种或两种。
在一些实施例中，所述的有机抗菌剂为季铵盐、季膦盐、有机锡、卤代胺、胍盐、脱乙酞基甲壳质以及壳聚糖及其衍生物类抗菌剂或两种以上混合使用。
在一些实施例中，所述溶胶混合液中，纳米银溶胶、无机抗菌剂、有机抗菌剂的摩尔浓度分别为：1.8-2.3mol/L、1.2-1.5mol/L、0.6-1.0mol/L。
在一些实施例中，所述的纺织物的制备方法，非织造材料浸泡于溶胶的时间为1-20小时。
另一方面，还提供一种用于医用防护服的纺织物，由上述的纺织物的制备方法制得。
另一方面，还提供一种主动广谱持久抗菌抗病毒医用防护服，由上述的用于医用防护服的纺织物作为面料制得。
有益效果：与现有技术相比，该发明的有益效果如下：
本发明的技术方案，将传统的金属离子抗菌抗病毒技术、有机物抗菌抗病毒技术、光触媒抗菌技术三者相结合，在不影响透气性的同时，赋予医用防护服持久有效的广谱的抗菌抗病毒性能，抗菌率达到99％以上，并且对流感病毒(H1N1和H3N2)的速杀效果非常好，抗病毒活性率99％以上，对皮肤安全无刺激性，防霉等级也达到了0级，而且水洗50次后，防护服的抗菌效果仍在99％以上，防护服可以水洗循环使用。
