What material is the diaper made of?
Nov 02, 2018

Superabsorbent resin (abbreviated as polymer SAP) is an excellent material for making baby diapers. It is made of starch and acrylate as the main raw material; it is characterized by water absorption and water storage.


Modern diapers generally consist of three main parts: a surface covering, an absorbent core and a base fabric. The surface coating adheres to the baby's body, which promotes rapid penetration of urine and effectively prevents back osmosis, keeping the surface of the diaper dry. The diaper on the domestic market is basically a non-woven surface layer. The breathable non-woven fabric can improve the air permeability inside the diaper. The water vapor can be circulated outside the diaper, and the moisture and hot air can be discharged in time to effectively reduce the incidence of eczema, soft and comfortable. Does not irritate the skin


The layer of the absorbent core layer is primarily capable of capturing and rapidly absorbing urine, dispersing urine or being able to diffuse it through the capillary layer to eventually absorb and store urine. The absorbent core layer of diapers on the domestic market is mainly composed of pure wood pulp (fluff pulp) and super absorbent resin (SAP).


Many diaper base fabrics in foreign countries have used non-woven fabrics that are more comfortable. However, due to the high price, the Peking diaper base fabric in the domestic market is still mainly composed of PE film.
