Description

一种增强型分区式复合芯体
技术领域
本发明涉及纸尿裤技术领域，特别涉及一种增强型分区式复合芯体。
背景技术
现今，纸尿裤成为一种常用的卫生用品，用于婴儿及失禁成人，尤其婴儿纸尿裤尤为受依赖，对于婴儿用品的高品质要求，对于纸尿裤的透气性，吸水后纸尿裤的芯体的性状要求日益提高，目前，很多的纸尿裤的芯体洗水后膨胀，由于婴儿的活动经常会使得芯体内部发生断层或起坨的现象，如此，芯体的液体吸收不均匀，影响使用的舒适感，且容易引起红屁股等现象，因此需要研究一种新型的纸尿裤芯体。
发明内容
根据本发明的一个方面，提供了一种增强型分区式复合芯体，包括底层、上层和高分子层，高分子层位于底层和上层之间，底层和上层设有多个连接部，连接部为压纹，压纹将高分子层分区固定。
上述的一种增强型分区式复合芯体，其有益效果是，多个连接部，即多条压纹将高分子层隔离成多个区域进行固定，使得高分子层固定分区成多个，增强了其牢固性，且使得其吸收均匀，不易断层或起坨，有效的预防使用纸尿裤后的不适感和红屁股等常见不良现象。
在一些实施方式中，压纹为超声波焊接或胶粘接。其有益效果是，压合方式为胶合、热合或超声波粘结中的一种或多种，将高分子层牢固的进行分区固定。
在一些实施方式中，压纹为多条，多条压纹将芯体表面呈现多个菱格状，菱格的中间为凸起的高分子固定区域。其有益效果是，菱格状压纹将高分子层分成多个菱格状的吸收膨胀区域，便于吸收均匀，不易断层或起坨。
在一些实施方式中，压纹为多条平行设置。其有益效果是，压纹为多条平行设置，将高分子层分隔成多个条纹区域，使得符合芯体多条高分子区域同时进行吸收，吸收均匀，不易外漏、断层拖起坨。
在一些实施方式中，增强型分区式复合芯体，还包括隔断区，隔断区为两个长条形环形区域，环形区域平行设置，环形区域由两条环形压纹组成，隔断区设置在复合芯体的两侧。其有益效果是，两条环形压纹组成的隔断区位于符合芯体的两侧，为了减少吸收的液体向两侧扩散，避免了侧漏。
在一些实施方式中，复合芯体的两侧中间边缘均为内凹型结构。其有益效果是，内凹结构为了适应腿部轮廓，增加舒适性和贴合性。
在一些实施方式中，增强型分区式复合芯体，还包括包覆层，包覆层包覆在底层的外表面及底层和上层的侧面。其有益效果是，包覆层包覆在底面及周边，能够进一步防止侧漏。
在一些实施方式中，底层和上层均为亲水无纺布或湿强纸。其有益效果是，亲水无纺布或湿强纸能够防止高分子层产生的粉尘透出。
在一些实施方式中，底层和上层的边缘采用针孔式热熔压合在一起。其有益效果是，采用针孔式热熔压将边缘牢固的固定在一起。
附图说明
图1为本发明一实施方式的一种增强型分区式复合芯体的结构示意图；
图2为图1所示一种增强型分区式复合芯体的剖面结构示意图；
图3为本发明另一实施方式的一种增强型分区式复合芯体的结构示意图。
具体实施方式
下面结合附图对本发明作进一步详细的说明。
图1示意性地显示了根据本发明的一种实施方式的一种增强型分区式复合芯体。如图所示，该增强型分区式复合芯体包括底层1、上层2和高分子层3，高分子层3位于底层1和上层2之间，底层1和上层2设有多个连接部4，连接部4为压纹，压纹将高分子层3分区固定。
上述的一种增强型分区式复合芯体，多个连接部4，即多条压纹将高分子层3隔离成多个区域进行固定，使得高分子层3固定分区成多个，增强了其牢固性，且使得其吸收均匀，不易断层或起坨，有效的预防使用纸尿裤后的不适感和红屁股等常见不良现象。
压纹的压合方式为胶合、热合或超声波粘结中的一种或多种。超声波焊接或胶粘接，将高分子层3牢固的进行分区固定。
压纹为多条，多条压纹将芯体表面呈现多个菱格状，菱格的中间为凸起的高分子固定区域。菱格状压纹将高分子层3分成多个菱格状的吸收膨胀区域，便于吸收均匀，不易断层或起坨。
压纹为多条平行设置。压纹为多条平行设置，将高分子层3分隔成多个条纹区域，使得符合芯体多条高分子区域同时进行吸收，吸收均匀，不易外漏、断层拖起坨。
增强型分区式复合芯体，还包括隔断区，隔断区为两个长条形环形区域5，环形区域5平行设置，环形区域5由两条环形压纹组成，隔断区设置在复合芯体的两侧。两条环形压纹组成的隔断区位于符合芯体的两侧，为了减少吸收的液体向两侧扩散，避免了侧漏。
复合芯体的两侧中间边缘均为内凹型结构6。内凹结构为了适应腿部轮廓，增加舒适性和贴合性。
增强型分区式复合芯体，还包括包覆层，包覆层包覆在底层1的外表面及底层1和上层2的侧面。包覆层包覆在底面及周边，能够进一步防止侧漏。
底层1和上层2均为亲水无纺布或湿强纸。亲水无纺布或湿强纸能够防止高分子层3产生的粉尘透出。
底层1和上层2的边缘采用针孔式热熔压合在一起。采用针孔式热熔压将边缘牢固的固定在一起。
本发明的底层1和上层2材料的断裂强力、断裂伸长率和透气量进行了试验检测，其产品性能如下：
以上显示本发明的底层1和上层2材料不易断裂，透气性好。
以上所述的仅是本发明的一些实施方式。对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
