What is the function of sanitary napkins?

Sanitary napkins are mainly used by women during menstruation to absorb menstrual blood and avoid soiling pants.

Sanitary napkin is an absorbent material, and its main material is polymer and polymer composite paper formed by cotton, non-woven fabric, pulp or the combination of the above materials.

Sanitary napkins are divided into three layers, namely, surface layer, absorbent core and bottom layer. The adhesive on the back of the sanitary towel is an impermeable material, which can keep menstrual blood in the sanitary towel to absorb menstrual blood flowing out of the vagina when women have menstrual cramps.

Sanitary napkins on the market are mainly divided into dry cotton and soft cotton from the surface material. How to choose according to personal physique and physiological characteristics;

1, dry net sanitary towel is made of a kind of chemical fiber material called "perforated membrane", which is characterized by fast water permeability, but chemical fiber may increase the probability of allergy.

Four misunderstandings should be avoided in sanitary napkins:

1. Use scented sanitary napkins: Many women think that choosing scented or cool sanitary napkins can mask the smell of menstrual blood and make it more comfortable to use, but it may cause allergies. Sanitary napkins without odor and foreign matter are safer, and it is not recommended to use cool and fragrant sanitary napkins.

Because women's vagina is in a slightly acidic environment, the essence added in sanitary napkins may be alkaline, which may destroy women's internal environment and easily lead to gynecological diseases such as vaginal itching and allergies.

2. Used sanitary napkins are piled up in trash cans: most bathrooms are dark and lack sunshine and humidity. Abandoned sanitary napkins are easy to breed mold in this warm and humid environment, which not only pollutes the air in the bathroom, but also probably awakens the mold lurking on the human skin, causing dermatoses such as tinea pedis, tinea manus and tinea cruris. If mold enters delicate and sensitive people, it may cause various medical diseases.

3. Sanitary napkins with strong absorbability: The immunity of menstrual women is lower than usual. A sanitary napkin will become a hotbed of bacteria after being used for 2 hours. If the sanitary napkin is not changed, it may lead to gynecological diseases such as vaginitis, cervicitis and pelvic inflammatory disease, and even lead to infertility. It is recommended to change sanitary napkins every 2 hours, and keep your hands clean when changing. If the weather is hot, it is necessary to encrypt the frequency of changing sanitary napkins.

4, abuse of pads: sanitary pads because of their small and simple, easy to use, deeply loved by women, often used before menstruation, ovulation, or when there are many leucorrhea. Vaginal skin is delicate and needs a very breathable environment. At present, most sanitary pads are not breathable enough, and the pads are easy to accumulate moisture, breed germs and cause various health problems. If you use sanitary napkins, don't forget to choose products with good breathability.

Especially if the leucorrhea is more, the color is yellow or bloody, and there is an odor, which may be due to diseases such as vaginal inflammation. At this time, the best way is not to use sanitary napkins, but to go to gynecology as soon as possible.
