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.
