      During menstrual period, many female I think that just using sanitary napkins is enough. In fact, the choice of underwear during menstrual period is also very important. During menstruation, you should wear cotton underwear with good breathability. It is better if you can choose menstrual pants with good elasticity, because its special design can keep the sanitary napkin optimally fitted, prevent shifting, and maximize its function.

      The anti-seepage principle of menstrual pants is also very simple. In terms of fabrics, there are two main types of menstrual pants. One is the coated anti-seepage type, which uses textile post-processing technology to apply an anti-seepage coating on the surface of ordinary fabrics to improve the anti-leakage performance of the fabric; the other is waterproof membrane-fitted menstrual pants. Simply speaking, a layer of physically waterproof polymer plastic film is tightly bonded with an ordinary textile base material, thereby giving the menstrual pants anti-leakage properties. From the appearance, there is not much difference between the two types of menstrual pants, but the feel is obviously different. The surface-coated menstrual pants are thicker but softer, and the feel of the anti-seepage part is basically the same as other parts; the waterproof membrane-fitted menstrual pants are thinner and have a "sandy" feeling when touched carefully.

      Although in general, the breathability of various menstrual pants has improved significantly compared with previous years, the breathability of coated menstrual pants is still better, and there is no discomfort even in the sultry summer weather.

      Due to the role of spandex, Lycra and other elastic fibers in the fabric, menstrual pants are relatively fit-fitting, body-shaping, and have good elasticity. Generally, it is enough to buy menstrual pants that fit well. Sometimes, in order to satisfy the psychological sense of security, it is okay to choose menstrual pants that are one to half a size smaller than the usual underwear, but you must adhere to the principle of erring on the side of smaller than too large. If they are too loose, the anti-leakage effect of menstrual pants will also be compromised.

      People who often wear menstrual pants have this experience. As the number of wear and washing of menstrual pants increases, their anti-leakage properties also gradually decrease. Because the active ingredients in the anti-leakage coating of menstrual pants will be slowly lost during the process of washing, drying and wearing, generally speaking, the optimal wearing life of coated menstrual pants is 6 to 10 months.

      Due to the characteristics of the fabric, once the menstrual pants are stained, the dirt will generally not penetrate into the fabric fibers, so they are very easy to clean. When washing, you can first soak it in clean water with detergent, and then rub it a little, and the dirt will basically leave no trace. It should be noted that in order to prevent the aging of the anti-seepage coating and polymer film and extend the service life of menstrual pants, it is best to use neutral or weakly alkaline underwear cleaners when cleaning. You should also avoid direct sunlight when drying, and avoid using various types of bleach.
