The gap between the absorbent core and the urethral opening in existing disposable diapers causes leakage, and replacing the entire diaper after it is saturated results in resource waste and increased costs.
It adopts a double-layer absorbent structure. The first absorbent core is integrated with the pant body, and the second absorbent core is raised and fitted at the urethral opening through an elastic component. It can be detached after saturation, combined with a detachable connection and a pre-set tear line design.
It improves absorption efficiency and leak-proof performance, extends usage time, reduces usage costs, and enhances comfort and hygiene safety.
