Description
Technical Field
The utility model relates to the technical field of sanitary products, and particularly relates to a dry antibacterial bamboo fiber sanitary towel.
Background
According to the survey report of the world health organization, 80% of women worldwide have different degrees of gynecological diseases, and 63% of the gynecological diseases are caused by the poor quality of sanitary napkins used by women during menstruation. Menstrual blood is rich in nutrients, and therefore, it becomes a "culture medium" for the growth of bacteria. After the sanitary towel is used for 15-18 minutes, the sanitary towel is very easy to become a culture base for breeding bacteria. Experiments show that after the common sanitary towel is continuously used for 20 minutes, the total number of surface layer bacteria can reach 107 per square centimeter. However, women have difficulty changing the sanitary napkin for 20 minutes. Therefore, the antibacterial property and the dryness of the surface layer material can be ensured, which is particularly important for the health of women in menstrual period.
At present, bamboo fiber surface layers on the market are mostly treated by adopting a bleaching process, the original characteristics of the bamboo fibers are damaged by the bleaching process, and the antibacterial activity is not obvious. Bamboo fiber has strong water absorption, but has stronger moisture desorption compared with the common chemical fiber material surface layer on the market. Therefore, the bamboo fiber surface layer commonly used in the market has poor dryness. The bamboo fiber surface layer on the market is usually coated and perforated on the sanitary ware to improve the dryness and the smoothness, the former destroys the antibacterial property of the bamboo fiber and reduces the skin-friendly property of the bamboo fiber surface layer, and the latter is still poor in dryness and the smoothness by means of physical perforation.
