背景技术
纸尿裤的结构一般分为面层、芯层和底层3层。在功能上纸尿裤产品应满足以下要求：一是整体的超倍吸水；二是与皮肤接触的面层导水快干；三是底层防漏。现有市场上普通的芯层的导流层由单层PP/PE和PE/PET双组份纤维经热风加固而制成，通常为单层纤网结构，存在着导流性能不好、瞬吸性差、易反渗等问题，因而研制开发综合性能良好的导流层，在发挥导流、储液和阻隔作用的同时，还能够完全降解环保，是非常关键和必要的。
发明内容
本发明所要解决的技术问题是：提供一种导流效果好的具有编织型吸收主体的纸尿裤。
为了解决上述技术问题，本发明采用的技术方案为：提供一种具有编织型吸收主体的纸尿裤，包括从上到下依次连接的面层、编织型吸收主体、防漏底膜和仿布底层；所述编织型吸收主体包括依次连接的斜网格吸收层网、正网格吸收层网、导流无纺布和密集斜网格吸收层网；
所述斜网格吸收层网为表面上设有斜网格状分布的通孔的机织布或针织布；所述斜网格吸收层网为表面上设有正网格状分布的通孔的机织布或针织布；所述密集斜网格吸收层网为表面上设有斜网格状分布的通孔的机织布或针织布；所述斜网格吸收层网的通孔的面积为所述密集斜网格吸收层网上的通孔面积的3-10倍；
所述斜网格吸收层网、正网格吸收层网和密集斜网格吸收层网分别由高分子吸水树脂纤维与导流纤维混纺而成。
本发明的有益效果在于：本发明具有编织型吸收主体的纸尿裤中，所述编织型吸收主体紧贴在面层下方使用，其中的斜网格吸收层网、正网格吸收层网、导流无纺布和密集斜网格吸收层网，他们通孔从上到下依次密集起来，分别起到了防起坨断层、快速吸收、导流、储液和防止反渗的作用，本发明所制备的纸尿裤具有优异的导流、透湿汽、瞬吸、良好的挺度、芯体稳定性、抑菌和生物降解等多种性能。

请参照图1以及图2，一种具有编织型吸收主体的纸尿裤，包括从上到下依次连接的面层、编织型吸收主体、防漏底膜和仿布底层；所述编织型吸收主体包括依次连接的斜网格吸收层网、正网格吸收层网、导流无纺布和密集斜网格吸收层网；
所述斜网格吸收层网为表面上设有斜网格状分布的通孔的机织布或针织布；所述斜网格吸收层网为表面上设有正网格状分布的通孔的机织布或针织布；所述密集斜网格吸收层网为表面上设有斜网格状分布的通孔的机织布或针织布；所述斜网格吸收层网的通孔的面积为所述密集斜网格吸收层网上的通孔面积的3-10倍；斜网格吸收层网和正网格吸收层网的通孔面积相等或相差1-2倍并相互错开；
所述斜网格吸收层网、正网格吸收层网和密集斜网格吸收层网分别由高分子吸水树脂纤维与导流纤维混纺而成。
上述具有编织型吸收主体的纸尿裤的加工方法：运用机织或针织法将SAP高分子吸水树脂纤维与导流纤维织制成网眼布，不同吸收层网间可以直接织成，也可以通过热熔胶粘合，制备得到编织型吸收主体；纸尿裤组成：面层+吸收主体+防漏底膜+仿布底层+防漏隔边+腰围组件，各组成用热熔胶粘合。组合流程：仿布底层无纺布喷上热熔胶，贴上防漏底膜；将编织型吸收主体按不同尺码长度分切后喷上热熔胶，然后贴合到防漏底膜上；将面层无纺布喷上热熔胶后，粘贴覆盖在编织型吸收主体上；防漏隔边和腰围组件同样喷上热熔胶后，粘贴到两侧及腰围部位；最后根据不同尺码长度及外形要求，分切出最终纸尿裤产品。
上述的具有编织型吸收主体的纸尿裤的有益效果在于：本发明具有编织型吸收主体的纸尿裤中，所述编织型吸收主体紧贴在面层下方使用，其中的斜网格吸收层网、正网格吸收层网、导流无纺布和密集斜网格吸收层网，他们通孔从上到下依次密集起来，分别起到了防起坨断层、快速吸收、导流、储液和防止反渗的作用，使所制备的纸尿裤具有优异的导流、透湿汽、瞬吸、良好的挺度、芯体稳定性、抑菌和生物降解等多种性能。
优选的，上述的具有编织型吸收主体的纸尿裤中，所述导流纤维为PE/PP复合纤维或PE/PET复合纤维。由上描述可知，PE/PP复合纤维或PE/PET复合纤维具有足够抗拉伸强度的同时亲水性好。
优选的，上述的具有编织型吸收主体的纸尿裤中，所述导流无纺布由PE/PET复合纤维和竹纤维混纺而成。竹纤维毛细管效应极强，具有良好的吸湿性和透气性，而且具有天然的抑菌、防螨、防臭、防虫功能，还可生物降解。由上描述可知，导流无纺布的上述设置使其在导流的同时，具有抗菌抑菌、生物降解的功能。
优选的，上述的具有编织型吸收主体的纸尿裤中，所述面层或仿布底层采用聚乳酸纤维和PE/PET复合纤维混纺的无纺布，所述聚乳酸纤维和PE/PET复合纤维的质量比为1:1-10。由上描述可知，聚乳酸纤维具有良好的透气性和抑菌抗霉性；导湿性能较好，快干，滑爽，有良好肌肤触感。采用聚乳酸纤维作为表层材料，利用聚乳酸纤维的天然抑菌性控制婴儿尿布疹产生的可能性，表层中的聚乳酸纤维给人体提供了充分的干爽性和光滑感。
