Abstract
Disclosed is an absorbent composite including a web formed from a mixture of fibrous material and particulate absorbent material. The web contains from about 15 to about 30 weight percent water. The described absorbent web is capable of containing relatively large quantities of particulate absorbent materials while maintaining an acceptable degree of flexibility.
