In general, baby diapers consist of three main components: the surface coating, the absorbent core, and the backing fabric.
Surface coating
The surface coating clings to the babybody, can promote the rapid penetration of urine and effectively prevent dialysis, diapers keep the surface dry. At present, 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 babyurine, and water vapor can be circulated to the baby urine-absorbing pad to remove moisture and heat in a timely manner. The chance of diaper rash occurring, soft and comfortable does not irritate the skin.
Absorption core
This layer is mainly able to capture and quickly absorb urine, disperse urine, or can diffuse it throughout the core by capillary action, eventually absorbing and storing urine. At present, the absorbent core of diapers in the domestic market is mainly composed of pure wood pulp (fluff pulp) and super absorbent polymer (SAP).
3. Base cloth
The backing of many diapers in foreign countries has used nonwoven fabrics that feel more comfortable, but due to the high price, baby diapers in the domestic market are still composed mainly of PE film.
