Description

一种补水保湿功能口罩及其制备方法
技术领域
本发明属于卫生用品技术领域，尤其涉及一种补水保湿功能口罩及其制备方法。
背景技术
常规一次性医用防护口罩采用无纺布作为口罩材料，疏水性强，不能及时将人体呼出气体中的湿气导出，佩带舒适性差。现有技术中也出现了具有补水保湿结构的口罩，专利号CN202023103225.X，一种具有芳香和通鼻通窍功能的保湿口罩，保湿口罩主块的内部设置有设备放置槽，所述设备放置槽内部的一端设置有主通气孔，所述主通气孔的内部设置有主通纱布，且主通纱布与主通气孔通过黏性连接，所述设备放置槽的内壁设置有保湿海绵块，且保湿海绵块与设备放置槽通过黏性连接，所述保湿海绵块的内部设置有芳香通鼻块放置块，且芳香通鼻块放置块与设备放置槽通过支撑竖柱固定连接。这种口罩虽然有保湿效果，但是结构复杂，防护性、舒适性较差。因此，研究出一种可以有效补水保湿功能，又可以达到防护要求的口罩具有重要的应用意义。
发明内容
为解决上述现有技术中存在的问题，本发明提供了一种补水保湿功能口罩及其制备方法，本发明的补水保湿功能防护口罩不仅具有防护功能，还具有较好的透湿性能，佩戴舒适性得到了极大的提高。
为实现上述目的，本发明采用如下技术方案：
一种补水保湿功能防护口罩，包括口罩主体，所述的口罩主体由内到外依次包括贴肤里层、过滤层、防护外层；
贴肤里层为玻尿酸天丝纤维面料，该面料玻尿酸含量180-200mg/kg，克重≤120g/m2；
过滤层为静电纺丝形成的膜，经过高温加热交联形成的亲水性纳米纤维过滤膜；
防护外层为涤纶纤维面料、聚氨酯纤维面料中的一种，防护外层上带有胶粒；克重≤160g/m2。
进一步地，所述水保湿功能防护口罩的细菌过滤效率≥95％，通气阻力≤49Pa/m2。
进一步地，本发明还提供了一种补水保湿功能防护口罩的制备方法，包括如下步骤：
(1)贴肤里层的玻尿酸天丝纤维面料的制备：将天丝面料浸泡在玻尿酸整理液中，烘干，使玻尿酸固着在天丝织物上；
(2)过滤层亲水性纳米纤维膜制备：以防护外层为接收布，在电压50-80kv的条件下，将静电纺丝液喷射在防护外层，在防护外层形成一层膜，然后与贴肤里层复合在一起，过滤层在中间，形成过滤层，使过滤层在防护外层与贴肤里层之间，然后与贴肤里层复合在一起，三层复合面料进入烘箱中，高温条件下水性高分子聚合物与交联剂交联；同时高温条件下胶粒融化，使得三层面料粘接在一起；
进一步地，所述步骤(1)贴肤里层的玻尿酸天丝纤维面料的制备：将天丝面料浸泡在玻尿酸整理液中5-30s，经过轧车，轧挤带液率为70％-80％，80-100℃下烘干5-10min，使玻尿酸固着在天丝织物上。
进一步地，静电纺丝液包括水性高分子聚合物、交联剂，水性高分子聚合物通过静电纺丝形成的过滤层耐水性差，遇水会溶解消失，所以加入交联剂，交联后该纳米纤维膜的耐水性才会提高，交联条件为140-150℃，交联时间8-10min，交联后过滤层的耐水性才会提高，这样在接触汗水、呼吸水汽的时候，过滤层不会溶解。同时高温条件下胶粒融化，使得三层面料粘接在一起。
进一步地，水性高分子聚合物包括聚乙烯醇、壳聚糖、明胶、海藻酸钠中的一种或几种。
进一步地，交联剂包括异氰酸酯交联剂、氮丙啶交联剂、咪唑交联剂中的一种或几种。
进一步地，步骤(2)是在140-150℃条件下将防护外层上的胶粒融化，通过导辊的张力，使得融化的胶粒渗透到里层，粘在一起，粘接强力≥8N。
进一步地，所述玻尿酸整理液包括玻尿酸、粘合剂、水；所述粘合剂为丙烯酸酯类，优选丙烯酸甲酯、丙烯酸乙酯、2-甲基丙烯酸甲酯和2-甲基丙烯酸乙酯。
进一步地，所述玻尿酸占整理液质量的0.05-0.1％，粘合剂占整理液质量的2-5％。
有益效果
本发明的补水保湿功能口罩，采用玻尿酸天丝面料，克重≤120g/m2，玻尿酸含量为180-200mg/kg，具有超薄透气性和补水保湿性，通过静电纺丝技术提供纳米纤维过滤膜，细菌过滤效率≥95％，通气阻力≤49Pa/m2，完全符合医用口罩的防护效果。本发明所述的补水保湿功能防护口罩不仅具有防护功能，还具有较好的透湿性能，佩戴舒适性得到了极大的提高。
