Description
技术领域
本发明涉及无纺布的技术领域，尤其涉及一种辅助调理经期的天然纤维水刺无纺布制备方法。
背景技术
卫生巾作为女性日常生活用品中不可缺少的一部分，与女性生活健康息息相关，经期间有三分之一的女性不同程度的遭受痛经，女性经血含有丰富的营养基，当经血排到卫生巾上后，一些细菌真菌在体温的作用下往往疯狂繁殖，进入体内攻击表层组织，产生妇科炎症，随着卫生巾的普及以及女性的需求，市面上出现了多功能卫生巾。
目前药物卫生巾相关的配方和制备工艺有很多，例如：
中国专利申请CN102697830A，一种防治经期疾病的药物组合物及其制备方法和应用，其活性成分由当归挥发油、川芎挥发油、紫草渗漉液、小檗碱制成。
中国专利申请CN103806269A,一种用于卫生巾的热感无纺布制备方法，包括热感整理液的配制、辊涂上浆以及烘干处理步骤。
以上相关配方制备的卫生巾生产工艺复杂，生产过程未隔绝细菌和真菌，易造成妇科炎症的发生。其药物的导入主要以辊涂的方式喷洒在卫生巾表层，往往不均匀，导致卫生巾表层质地较硬，与肌肤摩擦大，且药物主要集中在卫生巾表层，导致药物与肌肤接触量大，时效短，对皮肤有刺激，破坏人体自身清洁免疫系统，本发明主要提供一种利用微乳雾化“分子互渗”嫁接技术制备辅助调理经期的天然纤维水刺无纺布生产工艺，其操作简单，制备的产品经期预防感染效果明显，舒适柔软。
