The market share is gradually higher than that of PE sanitary napkins. The inner layer is mainly composed of cotton, non-woven fabric, paper pulp or a composite of high-molecular polymer and high-molecular polymer composite paper, used to absorb the outflow of menstrual blood. The design of the side is mainly used to prevent side leakage, because it will show an angle with the body of the sanitary napkin during use, and it is easier to rub against the groin. Therefore, the side of the soft material is more popular with women. The adhesive is water-impermeable and keeps the menstrual blood in the sanitary napkin. Adhesive sanitary napkins are convenient for fixing sanitary napkins on the inner side of underpants, and can reduce the displacement of sanitary napkins. The above bacteriostatic copper material can be arranged on the surface layer, inner layer or side of the sanitary napkin.

Diapers are mainly composed of surface layer, absorbent layer, breathable bottom layer, elastic material, closed system and other structures. The surface layer (inner surface coating layer) is a skin-friendly layer, which directly adheres to the baby's body, can quickly conduct urine to the absorption layer, and effectively prevent the re-infiltration, keeping the surface layer dry. The absorption layer is mainly able to quickly absorb urine, disperse urine or diffuse it into the entire absorption layer through capillary action, and finally absorb and store urine; it is mainly composed of pure wood pulp (velvet pulp) and super absorbent resin ( SAP) consists of a layered structure that locks urine firmly. The breathable bottom layer is mainly to prevent the leakage of urine and stool after absorption, and emit moisture to make it have excellent breathability. The elastic material can use elastic rubber bands, and the diaper adopts elastic rubber bands for the waist and legs, which can make the diaper closely fit the baby's body shape and body movement, and at the same time can help effectively prevent side leakage and back leakage. The closed system is composed of front waist stickers and left and right waist stickers. It has good adhesion performance and can be pasted many times. It can move freely no matter how the baby moves. The above bacteriostatic copper material can be arranged on the surface layer or breathable bottom layer of the diaper.
