Oftentimes different students reach different conclusions despite doing almost identical projects. Prior experiments are probably not a good source of resource information because of this, and we recommend going directly to the manufacturers instead. Many of them will have web sites which you can access and learn about the products and how they are made. A library research is also appropriate, where the student can learn about cloth making in general and the manufacture of diapers specifically. The student may also try Emailing the manufacturers to request more information about the product.
Most diapers contain some form of polyacrylate, a material which is extremely absorbent.
As background for diaper comparison we recommend that the student also research sodium polyacrylate and other forms of polyacrylate. The Materials Needed 1. Three diapers for each brand of paper towel to be tested. A large bowl or sink 3. A roll of making tape.
