Understanding diapers --- the basics of diapers"physical structure"
Generally speaking, diapers are composed of three main parts: surface cover layer, absorbent core layer and base fabric.
1. Surface coating
It is close to the baby's body, and its main function is to ensure the rapid penetration of urine and effectively prevent back seepage, so as to keep the surface of the diaper dry. The diapers in the domestic market are basically non-woven fabric surface layer. The breathable non-woven fabric can improve the air permeability inside the diaper, and the water vapor can flow out of the diaper, and the moisture and heat can be discharged in time, effectively reducing the chance of diaper rash , soft and comfortable without irritating the skin.
2. Absorbent core layer
The main function of this layer is to capture and quickly absorb urine, disperse urine or spread it throughout the core layer by capillary action, and finally absorb and store urine.
At present, the absorbent core layer of diapers in the domestic market is mainly a layered structure composed of pure wood pulp (fluff pulp) and super absorbent resin (SAP).
3. Base fabric
Many foreign diapers have used non-woven fabrics that feel more comfortable and breathable, and the market price is relatively high. The bottom fabric of domestic diapers is still mainly composed of PE plastic film, and the air permeability is relatively poor.
