I. Dry mesh sanitary napkins
Refers to sanitary napkins whose surface layer is made of various perforated films, mainly polyethylene, commonly known as PE film.
Second, cotton soft sanitary napkins.
Refers to sanitary napkins whose surface layer is made of various nonwoven materials, mainly polypropylene, commonly known as PP.
Third, pure cotton sanitary napkins.
Refers to sanitary napkins with pure cotton surface, mainly made of pure cotton non-woven fabrics.
Sanitary napkins are divided into three layers, namely, surface layer, absorbent core and bottom layer, and the materials of each layer are bonded by hot melt adhesive:
1, the surface layer is the part that directly contacts the skin, and its material is soft. The weaving and indentation on the surface will affect the reverse osmosis effect (dryness) of sanitary napkins.
2. The surface layer of PE perforated film and cotton surface layer are the two most commonly used materials. The PE surface layer with micropore design can make menstrual blood not easy to re-penetrate and make users feel dry.
3. The inner layer is mainly composed of cotton, non-woven fabric, paper pulp or polymer and polymer composite paper made of the above materials, which is used to absorb menstrual blood. The side design is mainly used to prevent side leakage.
Extended data:
Women's menstrual resistance is very poor, and not paying attention to nursing will cause various abnormalities in the body. According to the statistics of experts in earlier years, 38% people will suffer from serious gynecological diseases if they use unqualified sanitary napkins. Seventy-three percent of women will feel itchy, burning and burning locally during menstruation; About 80% of women will also have symptoms such as high fever, headache and abdominal pain.
The reason is that the external environment of female pelvis, uterus, cervix and so on are interlinked, which makes the female reproductive system vulnerable to external pathogens. Especially during menstruation, the resistance of reproductive organs decreases and is more fragile than usual. If you use unqualified sanitary napkins, it is easy to get infected.
