What are the structural components of diapers?

The structure of diapers: modern diapers generally consist of three main parts: surface covering layer, absorbent core layer and base fabric. The surface coating layer is close to the baby's body, which can promote the rapid penetration of urine and effectively prevent back seepage, keeping the surface of the diaper dry. The surface of the diapers on the domestic market is basically a non-woven fabric surface layer. The breathable non-woven fabric can improve the degree of air permeability inside the diaper. Water vapor can circulate outside the diaper to discharge moisture and heat in time, effectively reducing the chance of eczema. , Soft and comfortable, basically does not irritate the skin. The absorbent core layer is mainly able to capture and quickly absorb urine, disperse urine or diffuse it into the entire core layer through capillary action, and finally absorb and store urine. The absorbent core layer of diapers in the domestic market is mainly composed of pure wood pulp (fluff pulp) and super absorbent resin (SAP) to form a layered structure. In the base fabric part, many foreign diaper base fabrics have used non-woven fabrics that feel more comfortable, but due to the high price, the domestic market diaper base fabrics are still mainly composed of PE film.
