How does a diaper absorb liquid?
The secret, water-absorbing chemical in a diaper is a superabsorbent polymer called sodium polyacrylate. … The cotton-like fibers you removed from the baby diaper help to spread out both the polymer and the liquid so that the baby doesn’t have to sit on a mushy lump of water-filled gel.
How much urine do diapers absorb?
The average disposable diaper can hold 10 pees before being changed. Whether you use disposables or cloth, your baby should be changed every 2 hours during the day.

This shows Huggies absorbed 48 mL more of 5% salt water than Pampers. Both diapers absorbed more than 58 mL, the amount a newborn can urinate between each feeding. We believe the amount of cotton, the powdery sodium polyacrylate, the engineering design of the diaper, and other factors made Huggies more effective.
How does the polymer inside the disposable diaper work does it only absorb water?
The polymer gel in a dry diaper has only about 1 percent water, so the particles are very small. When the diaper gets wet, water molecules slip into the gaps between the polymer molecules to get closer to the sodium. The gel particles swell up.
How much can diapers absorb?
Since diapers should be changed before each feeding, the diapers should absorb a minimum amount of 58 mL of urine. (350 mL of urine / 6 feedings a day = 58 mL maximum amount of urine between each feeding.)…
