Description

一种防水透气复合面料
技术领域
本发明属于面料技术领域，具体涉及一种防水透气复合面料。
背景技术
复合面料是将一层或多层纺织材料、无纺材料及其他功能材料经粘结贴合而成的一种新型材料。
复合面料是一种非织造面料，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，而且还有棉质的感觉。它是新一代环保材料，具有无毒无刺激性、色彩丰富等特点，
传统的复合面料，主要分为天然材料和人造材料两大类。天然材料最常用的主要有棉布，丝织物等，它们具有柔软舒适，透气性好的优点，受到人们的青睐。但是，它们也存在不少缺点，如不防水，易皱难打理。这在一定程度上限制了这些布料的使用范围。如当在一些潮湿、多水的环境中，人们就不能在使用这些面料。而另一种被人们广泛使用的面料就是一些尼龙，聚会纤维等人造的化工面料。与天然织物不同的是，这些化工面料具有良好的防水性，而且轻薄抗皱耐用，容易打理。可是，这些人造化工材料往往透气性很差，舒适度不及棉布等天然织物。
针对上述技术问题，故需要进行改进。
发明内容
本发明是为了克服上述现有技术中的缺陷，提供一种防水透气复合面料,是由多层面料复合而成的，在保证防水功能的同时，还具有透气功能。
为了达到以上目的，本发明所采用的技术方案是：一种防水透气复合面料，包括从上至下依次布设的防水层、上复合面料层、基布层和下复合面料层；所述上复合面料层和下复合面料层分别连接在所述基布层的上下两面；所述基布层与上复合面料层和下复合面料层之间分别设有呈网格状的上纤维网和下纤维网，所述上复合面料层与上纤维网之间以及下复合面料层与下纤维网之间均通过胶水粘接。
作为本发明的一种优选方式，所述上复合面料层和下复合面料层均为透气面料，该透气面料由竹炭纤维面料组成，竹炭纤维面料包括若干横向经纱线和纵向纬纱线交织而成，形成网状结构。
作为本发明的一种优选方式，所述基布层为涤纶纤维织物，所述涤纶纤维的纤维度为10～400旦尼尔，所述涤纶纤维的复数为5～300。
作为本发明的一种优选方式，所述横向经纱线和纵向纬纱线为双股单纱构成。
作为本发明的一种优选方式，所述横向经纱线和纵向纬纱线为芳纶纤维。
作为本发明的一种优选方式，所述防水层与上复合面料层之间设置有粘合层，所述防水层为纳米纤维膜，所述纳米纤维膜的厚度是1～600微米，纤维平均直径是50～1000纳米。
作为本发明的一种优选方式，所述防水层为硅胶材质，硅胶的表面上布满若干个透散湿气的微孔。
作为本发明的一种优选方式，所述上纤维网和下纤维网的表面均设置有突起纹路，所述突起纹路为网格状或者条状。
作为本发明的一种优选方式，所述上纤维网和下纤维网上形成的突起纹路与上复合面料层和下复合面料层上形成的网状结构位置相对应。
一种防水耐摩复合面料的防水层由以下重量份的原料制备而成：N-甲基-2-吡咯烷酮1～5份，异氰酸酯2-10份，邻羟基苯甲酸钠40-60份,二氧化硅20-40份,防水浓缩液树脂80～150份，无水助剂10-20份，水性硅油40～50份，去离子水500～1000份；催化剂5-10份，柔顺剂 10～20份，所述防水浓缩液树脂由质量分数为15～25％的水性 氟碳树脂和75～85％的去离子水组成。
本发明的有益效果是：
本发明的一种防水透气复合面料，具有使用寿命较长，具有一定的防水效果设计巧妙，防水性能好且具有透气性的优点，提高了市场竞争力，达到了结构简单和设计合理的目的。
附图说明
图1是本发明实施例1结构示意图；
图2是本发明实施例1的上复合面料层1局部结构示意图。
图3是本发明实施例2防水层俯视图；
图中附图标记：上复合面料层1，基布层2，下复合面料层3，粘合层4，上纤维网6，下纤维网7，防水层9，微孔9-1。
具体实施方式
下面结合附图对本发明实施例作详细说明。
实施例1：如图1-2所示，一种防水透气复合面料，包括从上至下依次布设的防水层9、上复合面料层1、基布层2和下复合面料层3；所述上复合面料层1和下复合面料层3分别连接在所述基布层2的上下两面；所述基布层2与上复合面料层1和下复合面料层3之间分别设有呈网格状的上纤维网6和下纤维网7，所述上复合面料层1与上纤维网6之间以及下复合面料层3与下纤维网7之间均通过胶水粘接。
胶水一般采用热熔胶胶连固定，通过热熔 胶胶连能保证上复合面料层1、上纤维网6、基布层2、下纤维网7和下复合面料层3之间无缝固定，进一步提高防水性能；通过上纤维网6和下纤维网7将网布层2压在中间，然后再粘合即可，提高了复合面料的整体牢固性，延长了使用寿命。
上纤维网6和下纤维网7的表面均设置有突起纹路，所述突起纹路为网格状或者条状；上纤维网6和下纤维网7上形成的突起纹路与上复合面料层1和下复合面料层3上形成的网状结构位置相对应；采用上述方案，使得防水透气复合面料的通透性更好，能增大面料的透气性。
上复合面料层1和下复合面料层3均为透气面料，该透气面料由竹炭纤维面料组成，竹炭纤维面料包括若干横向经纱线3-1和纵向纬纱线3-2交织而成，形成网状结构；透气面料为涤纶纤维制成，网状透气层由涤纶纤维织成镂空形状，采用绗缝缝接，使其连接性好，增加面料的舒适性和通透性。
横向经纱线3-1和纵向纬纱线3-2为双股单纱构成，可提高布料的断裂强度； 横向经纱线3-1和纵向纬纱线3-2密度较高可使布料较为厚实，以提高抗高温阻燃的能力。
横向经纱线3-1和纵向纬纱线3-2为芳纶纤维；芳纶纤维是一种永久阻燃纤维，不会因使用时间和洗涤次数降低或伤失阻燃性能；该阻燃布料的结构合理，能够满足制作强度的要求。
基布层2为涤纶纤维织物，所述涤纶纤维的纤维度为10～400旦尼尔，所述涤纶纤维的复数为5～300。
基布层2为普通涤纶纤维织物，主要起支撑作用。基布层2的涤 纶纤维的纤维度为10～400旦尼尔（Denier）。本领域技术人员应当知晓，旦数或旦尼尔，是指在公定回潮率下，9000米纱线或纤维所具有重量的克数，克重越大纱线或纤维越粗，常用来表示化纤长丝、真丝等。
优选地，涤纶纤维的纤维度为10～100旦尼尔。更为优选地，涤纶纤维的纤 维度为30～70旦尼尔。
本实施例中，基布层2的涤纶纤维的复数为5～300，优选地，涤纶纤维的复数为30～100。本领域技术人员应当知晓，复数（F）表示纺丝时使用喷丝板的孔 数，也表示该规格的丝具有的单丝根数，例如72F，意思是纺丝时使用的喷丝板 有72孔，即该纤维有72根单丝。
粘合层4为PU/PVDF胶黏层，PU（Polyurethane）中文名是聚氨酯，PVDF （PloyVinylidene Fluoride）中文名是聚偏氟乙烯。PU/PVDF胶黏层的要成分是 PU/PVDF胶黏剂，将PU/PVDF胶黏剂用静电喷涂形式喷于机织物基布上，按 需求可配制不同PU/PVDF胶黏剂，从而可控制喷在基布上的PU/PVDF胶黏剂 的形态，分为液滴状（点状）和纤维状。胶黏剂的形状对复合织物中纳米膜与 基布间的胶黏强度，以及整个复合织物的防水透气性能有直接影响。
当PU/PVDF胶黏剂喷在基布上后，运用高压静电纺丝的方法将热塑性聚氨 酯以纳米纤维的形式喷于附有胶黏剂的基布上形成一层均匀的纳米纤维膜。 通过控制聚氨酯溶液浓度、静电纺丝时间和纺丝电压等调控纳米纤维膜的厚度， 从而调节整个复合织物的防水透气性能。
本实施例中，纳米纤维膜的厚度是1～600微米，纤维平均直径是50～1000 纳米。优选地，纳米纤维膜的厚度是10～200微米，纤维平均直径是400～600纳米。
实施例2：
本实施例内容与实施例1内容基本相同，相同部分内容不在重复，与实施例1不同的是：
如图3所示，防水层9为硅胶材质，硅胶的表面上布满若干个透散湿气的微孔9-1，通过微孔9-1增加面料的通透性。
