          How do ultra-thin baby diapers work

Before 1982, diapers relied on the absorbancy of cotton, paper and sponges to hold the um,

liquid in place. Unfortunately, those materials can only hold about 20 times their weight in water. 

The average diaper doesn’t really weight that much, so 20 times not very much equals leaks.

 

Today we have a much better situation. The use of super absorbent polymer materials such as 

sodium polyacrylate has dramatically increase the “storage capacity” of your typical diaper. Sodium 

polyacrylate was originally developed as an agricultural product. Spread over crop fields it helps 

even out the drench-drought cycle by releasing moisture as needed. It is a super-absorbing 

polymer that can hold up to 800 times it’s weight in water. Again, compare that with paper, cotton 

or sponges which hold about 20 times their weight in water.

 

This superabsorber is common used in diapers to provide super absorbency. This also means it 

is easier available if you have a diaper on hand. To harvest the polymer powder, rip open a 

diaper and place it inside a one gallon zip lock bag. Seal the bag and shake to release the 

powder from the other materials inside the diaper. The powder that will collect in the corner of 

the bag is the superabsorber.

 

In the early 1970s, super absorbent polymer was used commercially for the first time-not for 

soil applications as originally intended-but for disposable hygienic products. The first product 

markets were feminine sanitary napkins and adult incontinence products.

 

In 1978, Park Davis used super absorbent polymers in sanitary napkins.

 

Super absorbent polymer was first used in European in a baby diaper in 1982 when Schickendanz 

and Beghin, say added the material to the absorbent core. Shortly thereafter, Unicharm introduced 

super absorbent baby diapers in Japan while Proctor & Gamble and Kimberly-Clark in the USA 

began to use the material.

 

The development of super absorbent technology and performance has been largely led by demands 

in the disposable hygiene segment. Strides in absorption performance have allowed the development 

of the ultra-thin baby diaper which uses a fraction of the materials-particularly fluff pulp, which earlier 

disposable diapers consumed.
