Abstract
Description
Technical Field
[0001] This utility model relates to the field of sanitary pad technology, specifically a sanitary pad with a double-layer antibacterial structure. Background Technology
[0002] Panty liners are convenient to use and are very popular among women. Some women even use them every day except during their menstrual period. However, most users do not change panty liners as frequently as they do sanitary napkins. They usually only use one panty liner per day for more than 12 hours. Currently, panty liners have poor antibacterial properties, and prolonged use can easily cause vaginal dampness and sweating, which can lead to the growth of pathogens.
[0003] Therefore, a sanitary pad with a double-layer antibacterial structure is needed to improve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a sanitary pad with a double-layer antibacterial structure to solve the problems mentioned in the background art.

[0007] As a preferred embodiment of this utility model, the surface layer is made of organic pure cotton material.
[0008] As a preferred embodiment of this utility model, the first antibacterial sheet is made of natural bamboo fiber material.
[0009] As a preferred embodiment of this invention, the second antibacterial tablet contains tea tree oil.
[0010] As a preferred embodiment of this utility model, the breathable bottom membrane is made of nano-PE material.
[0011] As a preferred embodiment of this utility model, adhesive is provided at the bottom of the first adhesive sheet, the second adhesive sheet, and the breathable bottom film.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In this invention, an antibacterial layer is set on a sanitary pad with a double-layer antibacterial structure. The first antibacterial pad is made of natural bamboo fiber. Bamboo fiber has excellent moisture absorption and breathability, which can quickly absorb and evaporate moisture to keep you dry and comfortable. Bamboo fiber has natural antibacterial and bacteriostatic properties, which can inhibit bacterial growth. Bamboo fiber sanitary napkins not only have excellent antibacterial effects, but also effectively reduce menstrual odor, making them suitable for women with heavy menstrual flow and prone to side leakage. The second antibacterial pad contains tea tree oil, which is a natural plant antibacterial material with antibacterial, antiseptic, and anti-inflammatory properties. It can kill most bacteria, viruses, and fungi, and also remove odors, thus improving the antibacterial effect of the sanitary pad. Attached Figure Description
