wood pulp (usually bleached white with chlorine)
and super-absorbent polymers, usually sodium polyacrylate – a compound that can soak up to 30 times its weight in urine.
What is inside baby’s diaper that can absorb urine?
Super Absorbent Polymer (SAP)
The secret sauce inside disposable diapers since the mid-80s has been SAP. These tiny crystals are sprinkled inside the layers of the absorbent core of a diaper to absorb and trap fluid (i.e., from urine and wet poopy).
Why do diapers absorb urine?
The diaper’s inside layers need to absorb urine so it will stay put
. Cotton diapers work on a simple principle — provide lots of surface area to which water can stick. … Both have a large surface area with many small holes and fibers. When water wets part of a surface, it is attracted to neighboring parts.
What powder is inside a diaper?
Sodium Polyacrylate
is a white granular powder which rapidly absorbs water. It will instantly absorb from 500 to 1,000 times its mass in water. One of its greatest uses is in making diapers super-absorbent. Table salt, NaCl, destroys the gel and releases the water.

Why do diapers 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 does cloth diapering work?
Traditional cloth diapers
have an outer layer and then a removable, absorbent liner or insert
(sometimes called a pre-fold). All-in-one cloth diapers, with every layer contained inside the diaper, are most like a disposable—you wash the whole diaper when it’s dirty (rather than only replacing an absorbent insert).

How can I make my diapers more absorbent?
Use an incontinence pad
-An easy to way to increase the absorbency of your adult diaper is to add an incontinence pad that is also sometimes referred to as a booster pad. Incontinence pads are made from the same type of material as the adult diaper. This means that they can soak up urine and keep it away from the skin.

polymerizing acrylic acid and hydrolysis of the polyacrylic acid with an aqueous sodium hydroxide solution
.
What dissolves sodium polyacrylate?
Sodium polyacrylate is
soluble in water
