Abstract
Absorbent wet laid products are made containing cellulose fibers and cellulose ester staple fibers that are co-refined to obtain products and articles that have improved water absorbency and tensile strength or burst strength or both. The absorbent wet laid products can now be made with a synthetic fiber in the wet laid operation since cellulose ester can be subjected to a refining operation.
