Description

一种双层复合纤维材料及其制造设备、方法
技术领域
本发明涉及一种纤维材料，特别是一种双层复合纤维材料及其制造设备、方法。
背景技术
双层无纺布是由底层以及其上部的表层层叠而构成，在表层上设置有凸起结构，其用于减少表层与皮肤的接触面积，表层的底面设有连接部，连接部下方设置有胶水层，用于将表层与底层相贴合；但现有的双层无纺布具有以下缺点：干爽性，透气性有待提高、立体效果还有提升空间；此外由于采用胶水连接表层和底层，胶水会在粘合两层材料时粘平或破坏表层的凸起结构，胶水也会带来味道或从纤维材料内部渗透到材料表面影响到透气和吸水性，并且胶水粘合通常需要一定的静置时间和施加压力，更容易破坏成型的立体效果。
发明内容
为了克服现有技术的不足，本发明提供一种双层复合纤维材料及其制造设备、方法。
本发明解决其技术问题所采用的技术方案是：

所述加热装置包括分别设于所述凸面压花辊、凹面压花辊、第一压辊和第二压辊内的加温热油腔，所述热油腔的进出口接有热油管道。
所述凸面压花辊的温度小于所述凹面压花辊的温度，两者之间的温差范围在9-11℃之内。
一种双层复合纤维材料的生产方法，包括如下步骤：通过加热装置对凸面压花辊、凹面压花辊、第一压辊和第二压辊分别加热至指定温度；将表层纤维材料输送至凸面压花辊、凹面压花辊之间，通凸面压花辊、凹面压花辊使表层纤维材料加热形成凸起部以及穿刺形成透气孔；成型后的表层纤维材料输送至凹面压花辊、第一压辊之间，并与底层纤维材料通过凹面压花辊、第一压辊预热压粘合；粘合后的限位材料继续输送至凹面压花辊、第二压辊之间进行二次热压，得到成型的双层复合纤维材料。
本发明的有益效果是：本发明的表层纤维材料分布有凸起部，凸起部上设有透气孔，凸起部周围设有使表层与底层相连接的粘合部，表层和底层之间采用热压粘合，形成牢固美观和保持性好的立体结构，取代现有技术的胶水粘合，采用该双层复合纤维材料作为面层制成的尿裤、卫生巾或其他一次性吸收用品，减少纤维制品和身体的接触面积，改善透气和吸水性。

所述凸面压花辊1的两端设有第一齿轮5，所述凹面压花辊2的两端设有第二齿轮6，装配后，所述第一齿轮5与所述第二齿轮6啮合，凸面压花辊1作为主动轮带动凹面压花辊2转动，结构稳定可靠。
