Description

一种低呼吸阻力高效过滤口罩
技术领域
本发明涉及口罩技术领域，具体涉及一种低呼吸阻力高效过滤口罩。
背景技术
口罩是人们在各种场合中广泛使用的卫生防护用品。在佩戴口罩呼吸时，口罩对空气流动具有一定的阻力，当阻力过大时，尤其是老年人、体弱病者、小孩和存在呼吸系统疾病的患者，如果长时间佩戴极易因缺氧出现头晕、胸闷等不适状况，严重时还会造成肺损伤，因此，呼吸阻力是佩戴口罩时评价人体舒适性的主要指标。佩戴者呼吸时的阻力一般随着口罩过滤效率的提高而增大，设置的功能层越多，功能层的孔径越小，过滤效果也越好，但同时佩戴者呼吸时也会受到更大的阻力，进而导致佩戴者呼吸不畅，影响舒适性。因此，亟需研究一种口罩，提高过滤效率的同时能够具有低呼吸阻力，提高佩戴者使用时的舒适性。
发明内容
本发明的目的是克服上述不足，提供了一种低呼吸阻力高效过滤口罩，实现了高效过滤和低呼吸阻力，既能起到有效的过滤防护作用，又为佩戴者提供了舒适顺畅的呼吸体验。
为实现上述目的，本发明提供如下技术方案，一种低呼吸阻力高效过滤口罩，包括由外至内依次设置的面层、中间层、内层；

通过采用上述技术方案，通过静电驻极母粒、水驻极母粒及聚丙烯母粒制成的低呼吸阻力丙纶熔喷层具有优异的抗拉强度，且过滤效率达到97％以上，其中，静电驻极母粒保证低呼吸阻力丙纶熔喷层具有优异的静电吸附能力以及静电吸附能力的持久性，水驻极母粒使得低呼吸阻力丙纶熔喷层具有低呼吸阻力，提高佩戴者的舒适性。
优选地，所述低呼吸阻力高效过滤口罩还包括设于所述面层与所述中间层之间的静电棉层。
通过采用上述技术方案，设置于面层与中间层的静电棉层不仅可实现对PM2.5的高效过滤，而且具有蓬松效果，大大增加了柔软度和透气性，提升了佩戴的舒适性。
优选地，所述面层为丙纶纺粘无纺布外层，所述内层为丙纶纺粘无纺布内层。
优选地，所述低呼吸阻力丙纶熔喷层由以下重量份数的组分制成：静电驻极母粒8.5份、水驻极母粒1.5份、聚丙烯母粒90份。
进一步地，所述低呼吸阻力丙纶熔喷层的重量为25g。
进一步地，所述低呼吸阻力丙纶熔喷层由以下方法制备而成：
S1、称取配方量的静电驻极母粒、水驻极母粒及聚丙烯母粒；
S2、将步骤S1中所称取的静电驻极母粒、水驻极母粒及聚丙烯母粒依次加入至混料装置内搅拌混合均匀，得到混料；
S3、将步骤S2中所得混料加热熔融，得到熔体；
S4、将步骤S3中所得熔体依次进行过滤、均化、喷丝、热风牵伸、冷却，最后成网得到纤维网布；
S5、将步骤S4中所得纤维网布进行高压水刺驻极静电，即得低呼吸阻力丙纶熔喷层。
通过采用上述技术方案，步骤S5中高压水刺驻极静电是将高压水喷淋于纤维网布上，通过高压水在纤维网布上穿刺，使纤维网布上的网眼能够被更好的打开，高压水在纤维网布上穿刺的同时水流与纤维网布摩擦产生静电，进一步提高了低呼吸阻力丙纶熔喷层的静电吸附能力。
优选地，所述步骤S3中加热温度为250℃。
优选地，所述步骤S4中：高压水刺驻极静电过程中的水压为5kg/cm2。
与现有技术相比，本发明的有益效果在于：本发明一种低呼吸阻力高效过滤口罩，实现了高效过滤和低呼吸阻力，既能起到有效的过滤防护作用，又为佩戴者提供了舒适顺畅的呼吸体验。
