Abstract
An absorbent article comprises a first, liquid-permeable carrier layer and at least a second carrier layer. A carrier attaching mechanism, such as a water-sensitive adhesive, secures together the carrier layers to provide substantially attached zones and a multiplicity of substantially unattached zones thereof. The substantially unattached zones provide a plurality of pocket regions, and a high-absorbency material is located within the pocket regions to provide an absorbent laminate. Matrix fibers are dispersed within the high-absorbency material in the pocket regions, and the matrix fibers are present in a selected amount which, in particular aspects of the invention, can be within the range of about 0.1-10 weight percent, as determined with respect to the total weight of the absorbent material contained in the pockets.
