Description

一种微弹耳挂非织造材料及其制备方法和用途
技术领域
本发明属于非织造材料技术领域，具体涉及一种微弹耳挂非织造材料及其制备方法和用途。
背景技术
非织造材料俗称无纺布，是指定向或随机排列的纤维通过摩擦、抱合或黏合或者这些方法的组合而相互结合制成的片状物、纤网或絮垫(不包括纸、机织物、簇绒织物、带有缝编纱线的缝编织物及湿法缩绒的毡制品)。所用纤维可以是天然纤维或化学纤维，可以是短纤维、长丝或当场形成的纤维状物。非织造技术是源于纺织又高于纺织的材料加工技术，它结合了纺织、造纸、皮革和塑料四大柔性材料的加工技术，并充分结合和运用了诸多现代智能化的高新技术，目前非织造材料的用途越来越广泛，如制备口罩和眼罩。
在日常生活中，人们手机等电子产品使用时间越来越多，对眼睛的保护越加重视，蒸汽眼罩的使用也越来越多，因此蒸汽眼罩的耳挂质量要求也越高，目前的耳挂在使用时，由于材料的限制，长时间使用后弹性较弱，导致眼罩在使用时与皮肤贴近性不够，影响使用的效果。
CN101755083A公开了一种非织造材料，包含外部非弹性基层和包含弹性材料的辅助层，所述基层和辅助层被机械粘结在一起，所述机械粘结包括水缠结，所述机械粘结包括针刺，所述非织造材料经预拉伸，所述基层包含选自包含纺粘层、粗梳热粘层和熔喷层的组的层。其制备的非织造材料虽然具备了一定的弹性效果，但是整体弹性效果还是会受到上面指出的材料限制，导致眼罩在使用时与皮肤贴近性不够。
CN102272369B公开了一种非织造材料以及制造此类材料的方法，包括：一种无机的纤维以及一种多组份粘合纤维；该多组份粘合纤维在单长丝中具有一种低熔点的组分以及一种高熔点的组分；该低熔点组分的熔点比该高熔点组分的熔点低25℃至50℃，以使得该低熔点组分能熔化并且粘结至该无机的纤维上而同时该高熔点组分保持完整；并且该多组份粘合纤维由于具有与该无机纤维的类似的强度所以具有与该无机纤维的类似的可切性，其虽然提高整体材料的强度，但是在弹性方面仍然存在着较大的缺陷。
发明内容
微弹耳挂非织造材料及其制备方法和用途，本发明的微弹耳挂非织造材料整体具备良好的透气防水效果，具有良好的抗菌效果和弹性，制备成眼罩或口罩时，能够减少耳朵受力，更贴合于皮肤。
本发明的目的之一在于提供一种微弹耳挂非织造材料，为实现上述目的，本发明提供如下技术方案：
一种微弹耳挂非织造材料，包括：
基层，由聚酯纤维、MS舒弹纤维和阻燃腈纶混纺而成；
两层抗菌防护层，两层所述抗菌防护层分别设置在所述基层的上下两侧面，且两层抗菌防护层分别与所述基层粘接在一起；
两层防水透气层，两层所述防水透气层分别设置于所述抗菌防护层远离所述基层的一侧，两层所述防水透气层分别与抗菌防护层粘接在一起；
每一层抗菌防护层与每一层防水透气层上分别开设有若干等距均匀分布的微型孔洞。
