Diapers are mostly composed of the following parts: outer wrapping layer, absorbent core layer and base fabric. 1. The outer wrapper The outer wrapper can keep the child's body dry, quickly absorb urine and prevent side leakage. Nowadays, most of the best-selling diapers in shopping malls and supermarkets are non-woven fabrics. The baby will not feel too much irritation after wearing it. It is soft and comfortable. It discharges water vapor and moisture and heat to keep the diaper away from the baby. 2. Absorption core layer The main absorption layer is to use its capillary force to disperse the baby's urine to the entire surface layer, play a role in quickly absorbing and dispersing urine and finally storing urine. In major stores, the absorbent cores of the diapers we usually see are mostly layered and made of super absorbent resin and pure wood pulp. 3. The bottom fabric is affected by the price factor. The bottom of the most popular domestic diapers is mainly composed of a breathable polyethylene film composed of polymer organic compounds.
