Abstract
Description
Technical Field
[0001] This utility model relates to the field of physiological underwear technology, and in particular to a self-cleaning, antibacterial, and health-promoting physiological underwear. Background Technology
[0002] Menstrual underwear features an elastic band that extends from the crotch to the lower back, reducing sanitary pad slippage and maintaining breathability. This maximizes hygiene during menstruation and prevents stuffiness that can irritate the skin.
[0003] For example, the authorized notification number "CN210988247U" describes self-cleaning antibacterial menstrual underwear. This antibacterial underwear has an outer and inner crotch layer. The inner layer, which is the antibacterial layer in contact with the user's crotch, can be removed from the outer layer, allowing for replacement of the antibacterial layer. This ensures the underwear maintains a good antibacterial effect while keeping usage costs low. However, the inner layer is detachably attached to the outer layer with Velcro. Due to the thickness and material of the Velcro itself, it can be uncomfortable for the user. Furthermore, because the connection between the inner and outer layers is not tight, sanitary napkins can easily stick to the outer crotch layer and the underwear body during menstruation, resulting in uneven adhesion and easy displacement of the sanitary napkin.
