Description
技术领域
本发明涉及纸尿裤领域，具体涉及一种可生物降解的婴儿纸尿裤及其制备工艺。
背景技术
纸尿裤是一次性使用后即可抛弃的产品，相对于传统的尿布更方便卫生，越来越受到年轻父母的喜爱，纸尿裤一般以无纺布、卫生纸、绒毛浆、高分子吸水树脂、PE膜、橡皮筋等材料制成。其中PE高分子纸尿裤一般作为防渗漏外底层，这就要求其具有一定抗拉伸强，同时在防渗漏的前提下，透气性要好；
非降解型的一次性日常用品，现在处理方法是随生活垃圾一起焚烧或填埋，不仅浪费土地资源，而且处理不完善时对空气和水资源造成严重污染。
发明内容
有鉴于此，本发明提供了一种可生物降解的婴儿纸尿裤及其制备工艺，包括由内向外的亲肤层、吸收层、外底层；
（1）亲肤层厚度为0.6mm，分为上表面层、中间层和下表面层三层结构，三层通过120-150℃热熔复合的方式粘结成为一个整体，烘干时间3-5分钟；上表面层和下表面层厚度均为0.2mm，为难水解性生物降解性树脂薄膜，包含难水解性生物降解性树脂、以每100重量份生物降解性树脂的1-10重量份的量的聚乙醇酸和以每100重量份聚乙醇酸的20-70重量份的量的促进聚乙醇酸水解的无机粒子材料，无机粒子材料是碳酸钙，聚乙醇酸均匀分散于全部生物降解性树脂中，并且通过从聚乙醇酸释放的酸水解生物降解性树脂；中间层厚度均0.2mm，为竹纤维加捻成丝网，竹纤维加捻成丝网上分布有孔径0.5mm的透气孔；竹纤维从竹杆中提取；备料—压榨—粉碎—溶解—过滤—脱泡—纺前过滤—拉丝—后处理—加捻络丝机—纤维制品，溶解条件为：氢氧化钠溶液浓度25%~27%，温度：140℃~180℃，保温时间：3小时；加捻成丝机包括工作台、转动连接在工作台上的多个的料卷，料卷用于输送外层绳线以加捻成丝形成外层丝物；绳芯送料机构连接在工作台下方，用于输送绳芯；外层绳线的捻绳块用于限位，捻绳块上设有穿孔，外层绳线在穿孔下端面位置处形成外层丝物，外层丝物与绳芯均穿过穿孔设置，外层丝物将绳芯包覆形成；牵引机构用以将加捻成丝好的排离加捻成丝机，牵引机构与工作台固定连接；加捻成丝机还包括辅助包芯结构，辅助包芯结构一端卡接在绳芯与外层丝物之间以使绳芯与外层丝物之间形成间隔，并且辅助包芯结构的端部高于穿孔的下端面；
（2）吸收层厚度为1mm，为复合可降解水凝胶材料，复合可降解水凝胶材料中水凝胶与三维纤维材料为层叠结构、圆筒结构或相互包含结构，层叠结构为双层结构或三明治型叠层结构，即上下两层三维纤维材料包裹一层水凝胶；水凝胶由丙烯酸和丙烯酸甲酯的壳聚糖组成，质量比为1/1至3/1；圆筒结构即三维纤维材料包裹水凝胶形成圆筒形；相互包含结构即三维纤维材料孔隙中含有水凝胶构筑聚合物，水凝胶孔隙中也含有三维纤维材料；
（3）外底层厚度为0.5mm，为可降解高分子复合材料，按重量百分比计算的组分为：聚乳酸为20％、聚羟基烷酸酯为45％、淀粉改性聚乙烯为35％；
本发明的有益成果为：本发明提供了一种可生物降解的婴儿纸尿裤及其制备工艺，该方法制得的纸尿裤具有一定的抗拉伸强度，防渗漏性好，透气性好，还可以生物降解，对环境友好；具有广阔的市场前景和应用价值。
