技术领域
本发明涉及一种层状体无纺布及其制备方法。
背景技术
无纺布是一种非织造布，它是直接利用高聚物切片、短纤维或长丝将纤维通过气流或机械成网，然后经过水刺，针刺，或热轧加固，最后经过后整理形成的无编织的布料。具有柔软、透气和平面结构的新型纤维制品，优点是不产生纤维屑，强韧、耐用、丝般柔软，也是增强材料的一种，而且还有棉质的感觉，和棉织品相比，无纺布的袋子容易成形，而且造价便宜。目前，在一些领域需要无纺布具备高耐磨性能和高抗菌性，但是现有技术中的无纺布无法满足该要求，所以需要开发一种耐磨又抗菌的无纺布。
发明内容
针对上述现有技术的不足之处，本发明解决的问题为：提供一种耐磨又抗菌的无纺布及其制备方法。
为解决上述问题，本发明采取的技术方案如下：

进一步，所述的石膏晶须、丙烯酸树脂、高锰合金、碳化硅、六方氮化硼、氧化锌的重量份分别为：15份、100份、12份、13份、30份、7份。
进一步，所述的石膏晶须和六方氮化硼的重量比为1：2。
进一步，所述的无纺布为涤纶或者丙纶无纺布。
一种层状体无纺布的制备方法，步骤如下：
a、将丙烯酸树脂溶于热水中进行搅拌，得到丙烯酸树脂分散液；
b、将石膏晶须、高锰合金、碳化硅、六方氮化硼、氧化锌按照比例投入水中进行充分搅拌，得到改性分散液；
c、将改性分散液投入到丙烯酸树脂分散液中，进行充分搅拌，得到涂层分散液，同时对涂层分散液进行加热保温；
d、对无纺布表面进行绒面处理，通过刷子在无纺布的两侧进行挂刷，使得无纺布表面的纹理遭到破坏，形成绒面；
e、将d中经过绒面处理的无纺布直接投入到c中的涂层分散液中浸泡，同时对涂层分散液进行加热；
f、将无纺布从涂层分散液中取出，自然晾干即可。
进一步，所述步骤a中的热水温度为40至50℃，搅拌时间为40至50min。
进一步，所述步骤b中的搅拌时间为20至30min。
进一步，所述步骤c中的搅拌时间为70至80min，涂层分散液的温度控制在50至55℃。
进一步，所述步骤e中无纺布在涂层分散液中浸泡时间为20至30min，控制涂层分散液温度为55至60℃。
进一步，所述步骤f中晾干时间为10至12小时。
本发明的有益效果
