Description

一种滤水防油非织造材料及其制备方法
技术领域
本发明属于日用纺织领域，尤其涉及一种滤水防油非织造材料及其制备方法。
背景技术
非织造材料是一种不需要纺纱织布而形成的织物，只是将纺织短纤维或者长丝进行定向或随机排列，形成纤网结构，然后采用机械、热粘或化学等方法加固而成。它直接利用高聚物切片、短纤维或长丝通过各种纤网成形方法和固结技术形成的具有柔软、透气和平面结构的新型纤维制品。
由于上述非织造材料在使用中的优异特性，市场上日用品使用广泛，然而多数非织造材料中没有进行结构或/和表面的功能化处理，使得使用功能单一，在应用上受到限制，如在防油非织造材料上，没有设计滤水功能，在选择作为医用纱布及擦拭布时需要这种具备多功能的无纺布。
发明内容
本发明旨在解决上述问题，提供了一种滤水防油非织造材料及其制备方法，通过在将滤水层及防水防油层复合结构的来调整无纺布材料的性能，从而提高了无纺布滤水功能及抗油功能，解决功能单一的问题。
为达此目的，本发明采用以下技术方案：

优选地，所述防水防油层的上表面间隔设有若干条用于将该防水防油层的表面水分滤除的滤水区域。
优选地，在抗静电层上设有一层纳米氧化银抗菌层。
优选地，所述滤水层为棉纶纤维，该棉纶纤维表层经亲水处理。
一种滤水防油非织造材料的制备方法，按如下步骤进行：
a.防水防油纤维表面处理
配制防水防油整理剂，然后将聚丙烯纤维丝浸入到该配制的浸渍剂中，制成防水防油改性的纤维，浸润完毕后进入烘房烘干；
b.抗静电处理
将抗静电剂喷淋于上述步骤a中处理后的防水防油纤维表面，喷淋完毕后，进入烘房内再次烘干；
c.预处理
步骤b中得到的防水防油纤维经开松、梳理、成网和再梳理工艺处理；将滤水纤维首先经过亲水处理，然后经开松、梳理、成网和再梳理工艺处理；
d.加固整合
将步骤c中处理后的滤水纤维与防水防油纤维经熔喷或热合工艺加固后，部分滤水纤维穿过防水防油纤维形成导流线；
e.分割、成卷
再经过烘干、分割、成卷后得成品。
优选地，所述步骤a中防水防油层是经防水防油整理剂浸轧处理，该防水防油整理剂由如下组份按质量百分比构成：氟碳共聚物5～20％、二丙烯二醇3～6％、分散促进剂2～5％、硅烷偶联剂3～6％、余量为水。
优选地，所述步骤a中，浸轧处理时间为2～10min，优选5～6min。优选地，所述b步骤中，所述抗静电剂是阳离子型永久抗静电剂，优选季铵盐类抗静电剂。
优选地，所述步骤d中，所述滤水层的纤维刺入防水防油层的部分纤维克重为防水防油层的10～20wt％,优选10～15wt％。
本发明的有益效果为：本发明提供的一种滤水防油非织造材料，由于其在结构上增设防水防油层使表面可憎水抗油干扰，另外通过熔喷或热合工艺加固而复合一层滤水层，同时，使滤水层纤维刺穿到防水防油层表面形成导流线，复合而得的无纺布不仅具有滤水、憎水和抗油等功能，而且还设置了抗静电功能，可以广泛应用于医疗、日用品等方面。同时，本发明采用浸渍法处理聚丙烯纤维制备而得防水防油纤维，然后经过抗静电处理及水刺加固并形成导流线，工艺简单，而且工艺过程无污染。
