Hope this helps:
The absorbent pad is made of two essential elements: water-loving polymer and fibrous material. Microscopically the polymer molecules resemble long chains or ropes. Parts of the chemical ropes are made to interact with water molecules. When a big number of these polymer chains are cross linked they form a gel network that can be modified. The gel strength is like polymer and has the tendency to misshape. If the strength of the gel is too high, the polymer will not hold enough water. If the gel strength is too low, the polymer will misshape too easily and the distant particles in the pad will absorb the liquid too fast, forming gel that blocks the liquid from getting to the center pad particles.

What is polymer absorbance-swell project?
Disposable diapers contain a polymer, called sodium acrylate, which is useful for absorbing water. Do background research to learn about sodium acrylate, and how it reacts with water. Make sure that you understand the terms hydrophilic, polarity and hydrogen bonding. Cut out the middle, padded section of a disposable diaper. Cut this into equally-sized square pieces, approximately 10-12 cm on a side. Remove some of the stuffing material so that you can staple the open ends closed. Measure water into a quart jar to fill it half-way. Immerse a diaper pad square in the jar and leave it for at least twenty minutes. Take out the diaper pad square, and allow any dripping water to go back into the jar. Measure how much water is left in the jar, and subtract from the original amount to see how much water the diaper pad square absorbed. Here are some questions you can think about answering with this project. How much water can the diaper pad absorb? Ordinary table salt makes a strongly ionic solution, dissociating into positively-charged sodium ions and negatively-charged chloride ions. What effect will the presence of dissolved salt have on the ability of sodium acrylate to absorb water? How much salt water solution can the diaper pad absorb? (Note: a solution of 10 g salt in 110 ml of water will have about the same concentration of dissolved salt as baby urine.) Sugar makes a non-ionic solution. How much sugar water solution can the diaper pad absorb? How does temperature affect absorption? Disposable diapers contain a polymer, called sodium acrylate, which is useful for absorbing water.

Where can you get sodium polyacrylate?
Sodium polyacrylate can be purchased online from chemical suppliers, or in some cases, it can be found in baby diapers and certain household products like pet litter.
What is an asbestos pad?
An asbestos pad is a type of insulating pad used in older construction to provide heat resistance and insulation. It is made from asbestos fibers, which have since been found to be hazardous to health and are no longer used due to the health risks associated with asbestos exposure. If you suspect your building contains asbestos pads, it is important to have a professional inspect and handle the material for safe removal.

Who invented the disposable diaper?
The first absorbent pad to be used as a disposable diaper was invented in 1942 by Pauli Storm in Sweden; he made it from unbleached creped cellulose tissue. According to Wikipedia these early disposable diapers had the capacity to hold 100cc of urine, which was roughly one wetting. Although this was cumbersome it was certainly an improvement on the cotton variety because there was no laundering, no sterilizing of diapers and no mess.
When where diapers invent?
Ancient diapers were made of seal Skin, rabbit skin, milkweed leaves, swaddling bands.Linen and cotton diapers were developed in the 1800s.

Can a disposable diaper be reused?
The question squicks me, and my first response is 'Oh dear God I hope not.' The key word in Disposable Diaper is 'Disposable'. The things were made to be discarded. Logically speaking, the material found in the diaper that absorbs liquid from an infant's waste can be dried out, but you still have the other 'matter' left stuck to the absorbent stuff. There's a ton of bacteria in a used diaper, and even if you wash the thing in bleach, all you'll likely end up with is a smelly pile of paper and muck mush. Most disposable diapers are made of paper or similarly disposable material, after all. Would you reuse a tampon or sanitary pad? That's pretty similar to a diaper. pee in it twice before throwing it away
