Description
技术领域
本发明涉及纸尿裤技术领域，特别是一种高效吸收的纸尿裤。
背景技术
纸尿裤是婴儿常用的日用品，是纸尿片、纸尿裤、拉拉裤的统称。干爽的尿不湿可以使婴儿保持整夜的安睡，由于吸水性强，被俗称为"尿不湿"，现有的纸尿裤吸收扩散性不足，容易出现漏液和回流的现象，因此需要一种高吸收高扩散的纸尿裤对上述问题作出改善。
发明内容
针对现有技术中存在的不足之处，本发明的一种高效吸收的纸尿裤，采用如下技术方案：
本发明提供一种高效吸收的纸尿裤，包括纸尿裤主体和连接片以及芯体，所述纸尿裤主体的前端基面上沿设有粘胶贴，所述纸尿裤主体的后端中心处设有弹性腰带，所述纸尿裤主体的两侧设有腿围防护边，所述纸尿裤主体的后端两侧连接有连接片，所述连接片的外侧类连接有连腰带，所述连腰带的外侧连接有弹性带，所述弹性带的外侧连接有魔术贴，所述纸尿裤主体的内部中心处设置有吸湿区，所述吸湿区包括由贴近肌肤的内层、非贴近肌肤的外层和位于内层与外层之间的被内层包覆的芯体,所述芯体为包括高吸收高保水性SAP的上层和高加压高通液性SAP的下层。
进一步地，所述内层为由天然纤维和海藻酸铜纤维制成。
进一步地，所述海藻酸铜纤维占内层的40％-60％。
进一步地，所述外层为经处理剂处理后的天然纤维制成，所述处理剂包括聚氨酯、硅酮、自由蜡和碳氟化合物中的至少一种。
进一步地，所述高吸收高保水性SAP与高加压高通液性SAP的比为0.5-1.5:1。
进一步地，所述高吸收高保水性SAP和高加压高通液性SAP均为多孔耐盐性SAP。
进一步地，所述高吸收高保水性SAP与高加压高通液性SAP均采用包括聚丙烯酸钠、聚丙烯酸钠交联体、聚丙烯酸钾、丙烯酸-乙烯醇共聚物、淀粉-丙烯酸接枝聚合物中的至少一种制成。
进一步地，所述弹性腰带与弹性带均采用褶皱式亲肤松紧带。
进一步地，所述腿围防护边的外侧设有防漏裙边。
与现有技术相比，本发明具有的有益效果为：
1.本发明的高效吸收纸尿裤，其设置有弹性腰带和弹性带，且均匀褶皱式亲肤松紧带，给予了最大的自由度，从而提供了腰围最大的舒适度。
2.本发明的高效吸收纸尿裤，其吸湿区的内层为由海藻酸铜纤维与天然纤维制成的抗菌层，其设置于内层起到最先抗菌抑菌隔绝细菌的作用，同时因为抑菌作用，使该纸尿裤具备除臭无异味的功效。

附图说明
下面结合附图对本发明进行详细的说明。
图1为根据本发明的实施例的纸尿裤的结构示意图；
图2为根据本发明的实施例的纸尿裤的吸湿区的截面图。
纸尿裤主体-1，连接片-2，芯体-3，粘胶贴-4，弹性腰带-5，腿围防护边-6，连腰带-8，弹性带-9，魔术贴-10，吸湿区-11，内层-12，外层-13。
具体实施方式
现结合附图详细描述根据本发明的实施例。
参照图1-2，根据本发明的实施例的一种高效吸收的纸尿裤，包括纸尿裤主体1和连接片2以及芯体3，纸尿裤主体1的前端基面上沿设有粘胶贴4，纸尿裤主体1的后端中心处设有弹性腰带5，纸尿裤主体1的两侧设有腿围防护边6，纸尿裤主体1的后端两侧连接有连接片2，连接片2的外侧类连接有连腰带8，连腰带8的外侧连接有弹性带9，弹性带9的外侧连接有魔术贴10，本纸尿裤的弹性腰带5和弹性带9的设置给予了最大的自由度，从而提供了腰围最大的舒适度，弹性腰带5与弹性带9均采用褶皱式亲肤松紧带，可提高接触皮肤的舒适度，腿围防护边6的外侧设有防漏裙边，以进一步防止液体侧漏。
纸尿裤主体1的内部中心处设置有吸湿区11，吸湿区11包括由贴近肌肤的内层12、非贴近肌肤的外层13和位于内层12与外层13之间的被内层12包覆的芯体3,芯体3为包括高吸收高保水性SAP的上层和高加压高通液性SAP的下层。
优选的，内层12为由天然纤维和海藻酸铜纤维制成，海藻酸铜纤维优选占内层12的43％，海藻酸铜纤维具有很强的抑菌杀菌作用，其是通过离子交换法得到的，因而铜离子易与溶液中的钠离子发生离子交换，越来越多的钠离子进入纤维后，纤维本身由不溶于水的海藻酸铜纤维转换成水溶性的海藻酸钠后形成凝胶，这样铜离子分散在溶液中，由于游离的重金属铜离子到达细菌细胞膜时，后者带负电荷，使二者牢固吸附，这样铜离子逐渐透过细胞膜进入细胞，使某些酶变性或蛋白质凝固，阻止细菌蛋白质的合成及破坏细胞的渗透压，进而导致细菌死亡，由于人体的排泄物中因滋长细菌而产生臭味，这样在海藻酸铜纤维的抑菌杀菌作用下，同样也可起到除臭的作用。
本实施例的天然纤维包括不限于基于植物的天然纤维和基于动物的天然纤维，基于植物天然纤维包括但不限于棉、大麻、亚麻、苎麻、竹等，基于植物的天然纤维一般均有较强的吸水性，柔软，厚实耐用，基于动物的天然纤维如羊毛，其柔软，作为内层12的材料舒适而耐用。
优选的，外层13位于吸湿区11的上层，外层13为经处理剂处理后的天然纤维制成，处理剂为聚氨酯、硅酮和自由蜡制成，其主要用于提高外层13纤维疏水性，这样便不会使芯体3吸收的液体从铜纤维无纺布底层底层漏出。
优选的，所述芯体3为高吸水性聚合物,高吸水性聚合物包括高吸收高保水性的SAP上层和高加压高通液性的SAP下层,高吸收高保水性SAP与高加压高通液性SAP的配比为1.5:1时，两种材料的优势得到充分互补，既能发挥SAP的高吸水性，又能体现其高通液性。SAP是经过适当交联而形成具有三维空间网络的高聚物，其本身具有的亲水基和疏水基会与水分子相互作用，当遇到水分子时，整体呈致密性的高分子链上的亲水性离子迅速电离水解，而随着同种电荷的积聚，静电斥力在高分子链上也随之增大，正是这种静电斥力使得三维网络逐渐扩张，引导水分子进入树脂内部，同时为了保持电中性，与累积在高分子链上的电荷抗衡的另一种电荷不会向外部扩散，而被束缚在树脂网络内与网外形成较大的浓度差，从而产生较大的渗透压，进一步吸收水分子进入三维网络，而三维网络的弹性收缩力也会伴随网络的扩张而逐渐增加，作为抗衡力慢慢抵消静电斥力，最终使SAP达到吸水平衡。另外，高吸水高保水性SAP相对更便宜，两种SAP按1.5:1配比，成本有所降低。
优选的，所述高吸收高保水性SAP和高加压高通液性SAP均为多孔耐盐性SAP，多孔耐盐性SAP吸水后形成水凝胶的多孔网状结构，对其吸水性能的改进有十分重要的意义。
优选的，所述高吸收高保水性SAP采用淀粉-丙烯酸接枝聚合物中制成，其由淀粉与亲水单体丙烯酸接枝聚合然后用交联剂交联而成，制备方法包括淀粉糊化、冷却、接枝共聚、加压水解、冷却、酸化、离心分离、中和和干燥成品，其中四价铈作为引发剂，三氯化铝为交联剂；高加压高通液性SAP采用丙烯酸-乙烯醇共聚物制成，其由将醋酸乙烯酯与丙烯酸甲酯进行共聚，然后将产物用碱水解后得到乙烯醇与丙烯酸盐的共聚物，不加交联剂即可成为不溶于水的SAP，此类SAP在吸水后有较高的机械强度，适用范围较广。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点,对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
