Abstract

The present invention relates to a layered absorbent structure in the form of a laminate including liquid storage layers comprising particulate superabsorbent material and adhesive fibers. Notably, the absorbent structure includes a wicking layer positioned between the liquid storage layers, with the wicking layer desirably acting to improve fluid spreading and rewet performance of the absorbent structure. The wicking layer preferably comprises airlaid cellulosic fibrous material such as wood pulp, and may optionally include superabsorbent polymer. A bonding pattern of the wicking layer is oriented to enhance wicking and rewet performance.
