优选的，所述吸附层采用的材料为竹炭与具有蜂窝状微孔结构趋势的聚酯改性切片熔融纺丝而制成的竹炭纤维，且吸附层由竹炭纤维通过维纺织机纺织制成，所述无纺布基层与吸附层之间的粘合剂为缩水甘油酯类环氧树脂粘合剂。
优选的，所述防滑底层采用的材料包括热塑性聚氨酯弹性体和色母粒，所述色母粒的直径小于5mm，且色母粒的含水量小于0.05%。
优选的，所述无纺布基层外表面设置的憎水涂层为含氟硅的超低表面能丙烯酸树脂，喷涂含氟硅的超低表面能丙烯酸树脂制得的涂层表面具有超疏水效果，水接触角达到150°以上，滚动角小于10°。
优选的，所述防滑底层的下表面均匀设置有多组防滑纹，所述防滑纹的构成可以为多组矩形凹槽、多组斜向交叉的凹槽或多组环形凹槽。
优选的，所述无纺布基层的制备方法为将聚苯二甲酰苯二胺、聚酰胺纤维、橡胶软化剂和聚丙烯熔融后挤出，然后将挤出的熔体拉伸而形成连续长丝，并将长丝铺设成纤维网，纤维网再经过热粘合加固成无纺布基层。
优选的，所述橡胶软化剂为物理软化剂，且橡胶软化剂为由链烷烃、环烷烃、芳烃、沥青物质和含氮有机碱所组成的混合物。
（三）有益效果
与现有技术相比，本发明提供了一种耐磨无纺布，具备以下有益效果：
1、该耐磨无纺布，通过无纺布基层内设置有聚酰胺纤维，使得无纺布基层的耐磨性较高，提高了无纺布基层的使用寿命，通过无纺布基层内设置有聚苯二甲酰苯二胺，使得无纺布基层的抗老化性能较高，并且使得无纺布较易于耐高温、耐酸碱腐蚀，通过无纺布基层的外表面设置有憎水涂层，使得水接触到无纺布基层表面时，会因为涂层的憎水作用而滑落。
2、该耐磨无纺布，通过设置有防滑底层，且防滑底层为热塑性聚氨酯弹性体，使得无纺布的防滑性能较高，且提高了无纺布的弹性和耐磨性，通过设置有吸附层，且吸附层为竹炭纤维，使得无纺布具有较好的气味和汗水吸附能力，并且使得无纺布具有抗菌抑菌功能。
