Technical Field
The invention relates to a sterilization sanitary towel containing pure natural plant extract or essential oil.
Background
Disposable sanitary products, also known as absorbent disposable products, include feminine napkins, pantiliners, tampons, baby diapers, adult diapers and other adult incontinence products, pet pads, and the like. In the process of using the disposable sanitary product, the product is mostly in direct contact with the skin of a user, so that the discomfort of the user caused by the contact with the skin is reduced to the maximum extent in addition to the sanitary and safety characteristics of the product. The female has poor resistance in menstrual period, and various maladies of the body can be caused by careless adjustment. In early years, 38% of people can suffer from serious gynecological diseases by using unqualified sanitary towels; 73% of women will feel local skin itching, burning and burning pain during the menstrual period; about 80% of women also have symptoms such as high fever, headache, abdominal pain, etc. The reason is that the external environments of the pelvic cavity, the uterus and the cervix of the female are communicated, and the reproductive system of the female is easily attacked by external pathogenic substances due to the structure. Especially during menstruation, the resistance of the reproductive organs is reduced, and is more fragile than usual, and if an substandard sanitary napkin is used, infection is likely to occur. Menstrual blood is rich in nutrients, and therefore, it becomes a "culture medium" for the growth of bacteria. An experiment shows that after the common sanitary towel is continuously used for 2 hours, the total number of surface layer bacteria can reach 107 per square centimeter, potential safety hazards can be brought to women during the use period of the sanitary towel, and the problem can be thoroughly solved only by effective bacteriostasis during the use period.
At present, the sanitary napkins on the market are limited to surface layer antibacterial treatment, the antibacterial effect is reflected in the prevention of secondary pollution, and the components exerting the antibacterial effect are mostly industrial synthetic raw materials, so that potential side effects exist in long-term use.
