Abstract
A process is provided for making an absorbent material. A web is formed with at least one layer of a mixture of cellulosic fibers and superabsorbent material. The moisture content of the web is increased so as to increase the web density. Then, the web is compacted at an elevated temperature to further increase the web density and to effect hydrogen bonding within the web.
