Assignee:

Kimberly-Clark Worldwide, Inc. - Neenah WI

International Classification:

A61F 13/15
A61F 13/20

US Classification:

604368, 604367

Abstract:

An absorbent article includes an absorbent composite which comprises substantially water-insoluble, water-swellable, non-regenerated, carboxyalkyl cellulose fibers. The fibers have a surface having the appearance of the surface of a cellulose fiber and comprise a plurality of first intra-fiber multi-valent metal ion crosslinks and a plurality of second intra-fiber crosslinks selected from ether crosslinks or ester crosslinks. In addition, the absorbent composite has been subjected to a treatment to create interfiber bonding between the fibers of the composite either throughout the composite or only on the surface of the composite.
