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
