Diapers consist of three main parts
Understand the physical structure of diapers-diapers Generally speaking, diapers are composed of three main parts: surface covering layer, absorbent core layer and base fabric. 1. The surface coating layer is close to the baby's body, and its main function is to ensure the rapid penetration of urine and effectively prevent back seepage, keeping the surface of the diaper dry. The diapers on the domestic market are basically non-woven surface layers. Breathable non-woven fabrics can increase the degree of air permeability inside the diapers. Water vapor can circulate outside the diapers to discharge moisture and heat in time, effectively reducing the chance of diaper rash. , Soft and comfortable without irritating the skin. 2. The main function of the absorbent core layer is 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. At present, the absorbent core of diapers on the domestic market is mainly composed of pure wood pulp (fluff pulp) and super absorbent resin (SAP) in a layered structure. 3. Bottom fabric Many foreign diapers have used non-woven fabrics that feel more comfortable and breathable. The market price is relatively high. The bottom fabric of domestic diapers is still mainly composed of PE plastic film, which has poor air permeability.
