Description

一种卫生巾
技术领域
本发明涉及一种卫生用品，特别涉及一种卫生巾。
背景技术
随着经济的发展和生活水平的提高，人们对一次性卫生用品的消费需求越来多。同时随着消费观念的日趋成熟和开放，消费者希望使用到更舒适、更透气和更放心的产品。
目前市场上卫生巾具备基本的吸收能力，但是由于此类产品经面层、吸收层和底膜等多结构组成，各层次结构设计局限和选料不当，常常导致消费者使用时有闷湿不透气感且容易出现侧漏，另外闷湿条件下容易导致微生物滋生等，这些均会给消费者身心健康带来负面影响。
发明内容
为了克服现有技术的不足，本发明提供一种结构简单、透气性和干爽性能好的无纺布。
本发明解决其技术问题所采用的技术方案是：
一种卫生巾，包括自上而下依次层叠的面料层、芯片层、导流层、透气底膜、离型纸和包膜，上述相邻各层之间设置有结构胶，所述导流层和透气底膜之间设置有主芯体，所述主芯体的中央部位设置有边界封闭的透气集散部，所述透气集散部的长度至少大于所述主芯体长度的10%，宽度至少大于所述主芯体宽度的20%，深度至少大于所述主芯体厚度的30%。
优选地，所述透气集散部顶部与所述主芯体表面平齐。
优选地，所述透气集散部顶部高于所述主芯体表面，所述透气集散部的厚度小于所述主芯体高度的两倍。
优选地，所述主芯体是由木浆或无尘纸构成的
优选地，所述主芯体上设置有贯穿的透气孔。
优选地，所述透气孔的面积大小为0.25-25平方毫米。
优选地，单位面积上多个所述透气孔的排布密度为每平方厘米50个以下。
优选地，所述主芯体的下部还贴有第二芯体，所述第二芯体为无尘纸或无纺布材料。
优选地，所述第二芯体的面积大于等于所述透气集散部的面积，所述第二芯体的面积小于等于所述主芯体的面积。
优选地，所述透气集散部的形状为透气集散部的形状为矩形、圆形、椭圆形中的一种。
优选地，所述面料层和所述导流层的材料均为有明显空隙的无纺布。
本发明的有益效果是：本发明的导流层和透气底膜之间设置有主芯体，主芯体的中央部位设置有边界封闭的透气集散部，透气集散部减少侧漏，主芯体上还设置有透气孔，透气集散部和透气孔的组合除了保持足够的吸收能力外，大大改善了产品透气性能，同时可以加快分泌液吸收减少侧漏风险。从而有益于消费者身心健康，提升使用的舒适度。

下面结合附图和实施例对本发明进一步说明。
图1是本发明的结构示意图；
图2是主芯体的结构示意图之一；
图3是图2主芯体的结构侧视图；
图4是主芯体和第二芯体贴合的结构侧视图；
图5是主芯体的结构示意图之二；
图6是图5主芯体的结构侧视图；
图7是主芯体的结构示意图之三；
图8是图7主芯体的结构侧视图。
具体实施方式
参照图1至图8，一种卫生巾，包括自上而下依次层叠的面料层1、芯片层2、导流层4、透气底膜5、离型纸10和包膜11，上述相邻各层之间设置有结构胶，所述导流层4和透气底膜5之间设置有主芯体6，所述主芯体6的中央部位设置有边界封闭的透气集散部7，所述主芯体6是由木浆或无尘纸构成的，所述透气集散部7的长度至少大于所述主芯体6长度的10%，宽度至少大于所述主芯体6宽度的20%，深度至少大于所述主芯体6厚度的30%，所述主芯体6上设置有贯穿的透气孔8，透气集散部和透气孔的组合除了保持足够的吸收能力外，大大改善了产品透气性能，同时可以加快分泌液吸收减少侧漏风险，从而有益于消费者身心健康，提升使用的舒适度。
在本实施例中，所述透气集散部7顶部与所述主芯体6表面平齐，或者所述透气集散部7顶部高于所述主芯体6表面，所述透气集散部7的厚度小于所述主芯体6高度的两倍，所述透气集散部7的形状为矩形的、圆形的、椭圆形的、异形的等各类几何形状，透气集散部7的形状为矩形、圆形、椭圆形中的一种，透气集散部使得芯体的透气性大大提高，同时加快分泌液吸收减少侧漏风险。
在本实施例中，所述透气孔8的面积大小为0.25-25平方毫米，单位面积上多个所述透气孔8的排布密度为每平方厘米50个以下，透气孔位于主芯体6的任何部位，包括位于透气集散部7内，透气孔排列可以是等间距排列，可以是按几何图形排列，也可以无规则排列，透气孔的形状可以是圆形的、椭圆形、矩形、异形的等各类几何形状。
进一步的，为了增强所述透气集散部7的作用，所述主芯体6的下部还贴有第二芯体9，第二芯体9用于透气集散部7滴落的分泌液扩散和增强吸收，所述第二芯体9为无尘纸或复合吸收材料，所述第二芯体9的面积大于等于所述透气集散部7的面积，所述第二芯体9的面积小于等于所述主芯体6的面积。
所述面料层1和所述导流层4的材料均为有明显空隙的无纺布，面料层1和导流层4采用透气性良好的无纺布，如热风无纺布、纺粘无纺布及其打孔加工材料以及PE打孔膜和水刺无纺布等具有明显孔隙的材料，所述透气底膜5具有良好的透气性能和防水性能，所以该卫生巾具有良好的透气性能。
在本实施例中，采用本领域常用技术相邻各层之间设置有结构胶，所述面料层1和所述导流层4之间设置有第一结构胶12，所述导流层4和所述主芯体6之间设置有第二结构胶13，所述第二芯体9和所述透气底膜5之间设置有第三结构胶14，所述透气底膜5和所述离型纸10之间设置有背胶15。
最后应说明的是：以上所述仅为本发明的优选实施例而已，并不用于限制本发明，尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
