Description

透气无纺布
技术领域
本发明涉及一种无纺布，特别是一种透气无纺布。
背景技术
无纺布又称不织布，是由定向的或随机的纤维而构成，是新一代环保材料，具有防潮、透气、柔韧、质轻、不助燃、容易分解、无毒无刺激性、色彩丰富、价格低廉、可循环再用等特点。如多采用聚丙烯(pp材质)粒料为原料，经高温熔融、喷丝、铺纲、热压卷取连续一步法生产而成。因具有布的外观和某些性能而称其为布。
传统的无纺布大多由多层无纺布直接组合而成。由于无纺布多由短纤维和长丝无定向排列而成，因此其形成的无纺布在吸水膨胀之后，其中的短纤维和长丝之间的相互作用力急剧减弱，导致丧失透气性。
发明内容
本发明的目的在于，提供一种透气无纺布。本发明具有良好的透气性，从而提高舒适性。
本发明的技术方案：透气无纺布，包括依次设置的无纺布层、透气膜层和增强层；所述透气膜层两侧分别通过胶剂层与无纺布层、增强层连接；所述无纺布层包括由外至内依次设置的聚酯短纤维层、助剂层和芳香族聚酰胺纤层，所述助剂层与聚酯短纤维层、芳香族聚酰胺纤层的交界处分别设有渗透层；所述增强层是亚麻纤维、羊毛丝和棉纤维混纺编织布层；亚麻纤维、羊毛丝和棉纤维的混纺质量比是4:6：3。
前述的透气无纺布中，所述聚酯短纤维层、助剂层和芳香族聚酰胺纤层的厚度比是:10:3：9。
前述的透气无纺布中，所述助剂层与聚酯短纤维层、芳香族聚酰胺纤层的交界处分别设有渗透层。
与现有技术相比，本发明通过一定结构的无纺布层、透气膜层和一定结构的增强层有效结合形成复合无纺布，从而使得在保证具有一定的吸水性的情况下，具有良好的透气性，从而提高舒适性；本发明具有强度高、过滤性能好、透气性好的优点。
附图说明
图1是本发明的结构示意图。
具体实施方式
下面结合附图和实施例对本发明作进一步的说明，但并不作为对本发明限制的依据。
实施例。透气无纺布，包括依次设置的无纺布层1、透气膜层2和增强层3；所述透气膜2层两侧分别通过胶剂层与无纺布层1、增强层连接3；所述无纺布层1包括由外至内依次设置的聚酯短纤维层11、助剂层12和芳香族聚酰胺纤层13，所述助剂层12与聚酯短纤维层11、芳香族聚酰胺纤层13的交界处分别设有渗透层；所述增强层3是亚麻纤维、羊毛丝和棉纤维混纺编织布层；亚麻纤维、羊毛丝和棉纤维的混纺质量比是4:6：3。
所述聚酯短纤维层11、助剂层12和芳香族聚酰胺纤层13的厚度比是:10:3：9。
所述助剂层12与聚酯短纤维层11、芳香族聚酰胺纤层13的交界处分别设有渗透层。
本发明通过一定结构的无纺布层、透气膜层和一定结构的增强层有效结合形成复合无纺布，从而使得在保证具有吸水性的情况下，具有良好的透气性，从而提高舒适性；本发明具有强度高、过滤性能好、透气性好的优点。
