Abstract
本发明提供了一种尿不湿，其采用竹纤维与棉纤维混纺，进一步的，通过抗菌后整理，使得面料的抑菌率得到显著的提高，适宜于大规模产业推广使用。
Description
技术领域
本发明涉及人类用品领域，具体涉及一种抗菌、透气尿不湿，适用于婴幼儿儿童以及病患人群。
技术背景
尿不湿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”。
其中，高吸水性树脂(简称高分子SAP)是制造婴儿尿不湿的绝好材料，它是由淀粉和丙烯酸盐做主要原料制成的；突出特点是吸水和蓄水量大得惊人。
单单将传统尿布和尿不湿相比，在透气性上，当然是传统尿布好，而且好得多，因为它只有布，没有隔水物质。但用这样的对比结果来评判二者的优劣是非常不公平的。因为在用传统尿布时，人们通常在尿布外层用一层隔水的东西：绝对不透气的塑料纸。所以我们应该拿加了这层完全没有透气性可言的“完整版”传统尿布和尿不湿进行对比。纸尿裤用无纺布，衬上只让空气进出而不让水分子进出的料，所以虽然透气性不能与纯布相比，但比起“完全版”传统尿布来，透气性可就要好得多。
随着生产工艺的不断改进，尿不湿已从最初防漏、吸收尿液的单一功能，改进为既防漏透气又吸尿抗菌，且增加了伸缩弹性腰围、立体防漏隔边等多种功能。
现代纸尿裤一般由三个主要部分组成︰表面包覆层、吸收芯层和底布。表面包覆层紧贴婴儿的身体，能够促使尿液快速渗透并有效阻止回渗，保持尿裤表层干爽。
国内市场上的纸尿裤基本上是无纺布面层，透气无纺布能提升尿裤内部的透气程度，水蒸气可以流通至纸尿裤以外，及时排出湿气、热气，有效减少湿疹发生几率，柔软舒适基本上不刺激皮肤。吸收芯层：这一层主要是能够俘获并快速吸收尿液、分散尿液或能通过毛细作用把它扩散到整个芯层中、最终吸收并储存尿液。国内市场上纸尿裤的吸收芯层，主要是由纯木浆(绒毛浆)和高吸水树脂(SAP)构成层状结构。底布部分：国外很多纸尿裤底布已经使用感觉更为舒适的无纺布，但由于价格偏高，国内市场的倍康纸尿裤底布仍主要由PE膜构成。
CN201558229U公开了一种负离子婴儿纸尿裤，其特征是：由两块纤维布、一块负离子芯片、一块吸水棉和锁水因子组成，在一块纤维布上贴合一块吸水棉和锁水因子，在吸水棉和锁水因子上再贴合一块负离子芯片，然后在上层再贴合一块纤维布。但是该纸尿裤对于杀菌效果并没有提及，是否能够抑制湿疹的发生也没有涉及。
CN104264471A涉及一种婴儿尿不湿，通过选择合适的抗菌剂，对内衬亲水无纺布进行抗菌预处理，抗菌剂的配方如下(组分及重量百分比％):水溶性壳聚糖4-8、纤维素酶1-5、柠檬酸1-5，聚乙二醇1-5、软水加至100。所述组分复杂，成本复杂，工艺也不简单，并不适合大规模推广应用，而且效果也低于预期。
基于现有的缺陷，针对杀菌，透气预防湿疹发生的尿不湿是本领域迫切需要解决的技术问题。
