Period panties is the underwear worn during the menstrual period. The design of the period panties is an elastic belt extending from the crotch of the underwear to the back waist, which reduces the sliding of the sanitary napkin and maintains the breathability of the crotch. So what is the principle of period panties? Let's take a look at it with the editor.

The principle of impermeability of period panties is very simple. From the perspective of fabrics, there are two main types of period panties, one is the coating impermeable type menstrual period proof panties, which uses the textile post-processing technology to improve the impermeability of the fabric by applying an impermeable coating on the surface of the ordinary fabric; the other is the impermeable type. It is a waterproof film bonding type. Simply speaking, a layer of physical waterproof polymer plastic film is tightly bonded with ordinary textile base materials, thereby giving period panties impermeability. In terms of appearance, these two kinds of period panties are not much different, but the feel is obviously different. The surface-coated period panties is correspondingly thicker, but softer, and the feel of its impermeable part is basically the same as that of other parts; waterproof membrane Fitted period panties is relatively thin, and it feels "rustling" when you touch it carefully.

Can you wear period panties?

The anti-leakage principle of period panties is that a layer of waterproof fabric is added to the bottom of the underwear. As a result, the breathability of leak proof menstrual period panties is necessarily worse than that of ordinary underwear, so it is best not to wear period panties in normal times. In life, we must develop the habit of washing and changing underwear frequently. It is recommended to change it every day, especially in summer, and the longest should not exceed 2-3 days.

When washing, separate it from outerwear and hand wash with soap as much as possible. After washing, do not directly expose to the sun, first put it in a cool place to air dry, and then put it in the sun to disinfect. Otherwise, the underwear is easy to harden and deform. In addition, the underwear is best placed alone, you can buy some special storage bags, or put it in a clean plastic bag, so as to avoid dust and bacteria, which will affect your health.

Length of use of period panties

People who often wear period panties have such experience. With the increase of wearing and washing times of period panties, the impermeability of period panties is also slowly attenuating. Why is this? The active ingredients in it will be slowly lost with the process of washing, drying and wearing. Generally speaking, the best wearing life of coated period panties is 6-10 months. Buy the right size that works for you. If the size is too small, it is easy to put pressure on the abdomen, waist and buttocks, and it is not easy to wear during menstruation, which affects the health of the body. If the size is too large, it will be loose and unobtrusive, which will greatly reduce the anti-seepage function of period panties.
