How baby diapers work

Baby diaper is an indispensable product in the life of infants and young children. Its working principle is mainly to keep the baby dry and comfortable by absorbing urine and preventing side leakage. Understanding how it works helps parents choose and use diapers correctly.


The main working principle of a baby diaper lies in the design of its absorbent layer. Modern diapers typically employ superabsorbent materials, such as polymeric superabsorbent resins (SAP), for absorbing urine. SAP has high water absorption properties, which can quickly absorb and lock urine inside, keep the diaper surface dry, prevent urine from directly contacting the baby's skin, and reduce the incidence of diaper rash.
In addition, the design of the diaper also takes into account the leak-proof factor. The diaper is surrounded by elastic leg openings and abdominal girth design, which can fit the baby's legs and waist and effectively prevent urine side leakage. Some diapers are also designed with a multi-layered absorbent core and drip strips to further improve the efficiency of urine absorption and prevent side leakage.
Proper use of baby diapers is also crucial. Parents need to change diapers regularly to keep them clean and dry, and to avoid red buttocks caused by prolonged contact with baby's skin. In addition, proper size selection and tightness adjustment can also ensure that the effect of the diaper is maximized.
In general, the working principle of baby diapers is mainly to keep the baby hygienic and comfortable through the use of high-absorbent materials and the designed leak-proof structure. Proper selection and use of diapers is essential for the health and well-being of infants and young children.
