Underwear protects private parts, and women's private parts are easily infected with bacteria. If you don't wear underwear, the private parts will have a larger area of contact with bacteria and are more susceptible to infection.
The special design of sanitary pants can effectively prevent the side leakage and back leakage of female menstrual blood, and at the same time, it also takes into account the breathability and comfort. The characteristics of waterproof material make cleaning more convenient, which can greatly reduce the residue of bacteria during menstruation and ensure the hygiene of sanitary pants to the greatest extent.
2. Different materials
The material of underwear is relatively common, and there is no impervious coating.
The anti-seepage principle of sanitary pants is very simple. As far as fabrics are concerned, there are mainly two kinds of sanitary pants. One is the coated anti-seepage type, which improves the anti-seepage performance of fabrics by coating anti-seepage coatings on the surface of ordinary fabrics and using textile post-treatment technology.

The anti-seepage principle of sanitary pants is very simple. From the fabric point of view, there are two main types of sanitary pants. One is the coating anti-seepage type, which uses textile post-treatment technology to improve the anti-seepage performance of ordinary fabrics by coating anti-seepage coatings on their surfaces; The other is waterproof film bonded sanitary pants, which simply means that a layer of physical waterproof polymer plastic film is tightly bonded to the common textile substrate, thus giving the sanitary pants anti-seepage performance.
From the appearance, there is not much difference between the two kinds of sanitary pants, but the feel is obviously different. The sanitary pants with surface coating are thick, but soft, and the feel of the impervious part is basically the same as that of other parts. The waterproof film is relatively thin, so you will feel "rustling" when you touch it carefully.
Because of the elastic fibers such as spandex and lycra in the fabric, sanitary pants are more fit, body-shaping and elastic, and generally enough to buy. If the size is too small, it is easy to bring pressure burden to the abdomen, waist and buttocks, and it is not easy to wear during menstruation, which affects your health. If the size is too large and too loose, the anti-seepage function of physiological underwear will be greatly reduced.
Sometimes, in order to satisfy the psychological sense of security, it is no problem to choose sanitary pants that are one yard to half a yard smaller than the usual underwear, but we must grasp the principle that small is better than good. If it is too loose, the anti-seepage effect of sanitary pants will also be discounted.
