Description

Wearable hygiene products Technical Field

[0001] The present invention relates to the field of sanitary care, and in particular to a wearable sanitary product. Background Art

[0002] Diapers are widely used by infants, young children, and dependent patients. Existing diapers generally consist of a top layer, a core, a waterproof membrane, and a back layer. When worn, the top layer contacts the skin and directs urine toward the core, which absorbs the urine. The top layer then wraps around the front, middle, and back of the crotch.

[0003] When the surface layer and the core absorb a certain amount of urine, the user's skin is always in contact with the urine in the soaked surface layer. On the one hand, it reduces the user's experience. On the other hand, it may irritate the user's skin and induce eczema, causing red papules on the skin and itching.

[0004] Therefore, there is a need for further improvement of existing diapers.

[0005] The information disclosed in this background section is only intended to enhance understanding of the overall background of the invention and should not be considered as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.
