摘要：

为实现纯棉水刺非织造材料单向导水无氟整理工艺的工业化,采用自制的雾化设备,并利用体积分数为0.67%的德国无氟拒水剂RUCO-DRY ECO 对纯棉水刺非织造材料进行单面拒水喷雾整理,测试了不同喷雾时间整理材料的物理力学性能、接触角、液态水分动态管理能力等性能,分析讨论了其物理力学性能基本无变化以及接触角、液态水分动态管理能力变化的原因,并采用经过此种工艺整理过的纯棉水刺非织造材料进行了纸尿裤面层性能测试。结果表明:其单向传递指数(AOTC)可达1 093%,液态水动态传递综合指数(OMMC)可达0.960 6;在保证纯棉材料不反渗的前提下,液体穿透时间可达4 s。

Abstract:

In order to realize the industrialization of pure cotton spunlace non-woven materials single-directional water-free fluorine-free finishing process, self-made atomization equipment and the German fluorine-free water repellent RUCO-DRY ECO with a volume fraction of 0.67% were adopted to one-side water-repellent spray finish the cotton spunlace non-woven materials. This paper studied the physical and mechanical properties, contact angle and moisture management tester(MMT)performance of the materials after finishing for different spray time, discussed the reasons for the little change of physical and mechanical properties and the changes of contact angle and MMT performance, and carried out the diaper surface performance test of the finished cotton spunlace non-woven materials. The results show that its one-way transfer index (AOTC) can reach 1 093%, the liquid water dynamic transfer index (OMMC) can reach 0.960 6. Under the premise of ensuring pure cotton material does not reverse osmosis, the liquid penetration time can reach 4 s.

Key words: self-made spray device, pure cotton spunlace non-woven material, one-sided water repellent, non-fluorine finishing, side layer material of diaper
