Description

Bacteriostatic sanitary towel

Technical Field

The invention belongs to the technical field of sanitary products, and particularly relates to an antibacterial sanitary towel.

Background

The sanitary towel is an absorbent material, the main material is cotton, non-woven fabric, paper pulp or high molecular polymer and high molecular polymer composite paper formed by the composite of the above materials, the side design is mainly used for preventing side leakage, and the back glue of the sanitary towel is a waterproof material, can retain menstrual blood in the sanitary towel and is used for absorbing the menstrual blood flowing out from the vagina when women have menstrual flow.

The sanitary towel directly contacts with the mucous membrane tissue of the human body to absorb menstrual blood, and the menstrual blood contains rich nutrient substances and is easy to become a culture medium for breeding bacteria. And is also female during menstrual periodThe experiment shows that the total number of surface layer bacteria can reach 10 per square centimeter after the common sanitary towel is continuously used for two hours⁷And (4) respectively. Therefore, potential safety hazards can be brought to women during the using period of the sanitary towel, and the problem can be thoroughly solved only by effective bacteriostasis during the using period.

At present, sanitary napkins on the market are various in brands and varieties, but most of the sanitary napkins mainly focus on solving the problem of absorbing liquid, and generally do not have the functions of antibiosis and sterilization.

The existing sanitary towel with the antibacterial function is added with the Chinese herbal medicines by being crushed into powder, so that the antibacterial effect is achieved. However, the antibacterial effect of the sanitary towel is unsatisfactory, and the main reason is that traditional Chinese medicinal materials are not treated, have a lot of mixed bacteria, are added into the core layer of the sanitary towel to easily pollute the towel body, are easy to mildew within the shelf life, cannot guarantee the validity period of the product, and can still be infected and diseased when being used by women. Severe symptoms such as dysmenorrhea and inflammation. Therefore, the development of a highly effective bacteriostatic sanitary towel is urgently needed.
