Problems solved by technology

[0002] At present, some sanitary napkins on the market have poor antibacterial ability, bacteria are easy to breed in the humid and hot environment inside the sanitary napkin, and women have poor resistance during menstruation, which is easy to cause physiological diseases and other problems. Materials with strong antibacterial ability. There are some sanitary napkins on the market that use nano-silver for antibacterial, but most of these sanitary napkins are only sprayed with nano-silver material on their surface layer, the actual antibacterial ability is limited, and this type of sanitary napkin is easy to A large amount of nano-silver material is lost, resulting in the decline of antibacterial ability and the increase of production cost, which is not conducive to popularization and use

Abstract

The invention discloses a nano-silver antibacterial sanitary pad and a production method thereof, and relates to the field of physiological hygiene products. The nano-silver antibacterial sanitary pad comprises a surface layer, an absorption layer and a bottom layer, wherein the absorption layer is formed by compounding non-woven fabric, the bottom layer is formed by compounding a PE breathable film and non-woven fabric, and the surface layer is composed of a base material and antibacterial liquid. The preparation method of the nano-silver antibacterial sanitary pad comprises the three steps of antibacterial liquid preparation, raw material preparation and fitting forming. According to the nano-silver antibacterial sanitary pad and the preparation method thereof, the antibacterial liquid contains nano-silver and O-carboxymethyl chitosan, so that the sanitary pad has excellent antibacterial ability, the female infection risk is reduced, and physiological hygiene and health of women are ensured; the antibacterial liquid containing the nano-silver material is attached to the surface layer in an impregnation mode, so that the overall antibacterial ability is improved; and the surface layer filled with the antibacterial liquid after impregnation is dried in an extrusion mode, so that the loss of the antibacterial liquid is reduced, and the utilization rate of the antibacterial liquid is increased.
