Abstract

An absorbent article comprises a first, liquid-permeable carrier layer and at least a second carrier layer. A water sensitive attaching mechanism secures together the carrier layers to provide substantially attached zones and 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. A secondary attaching mechanism secures together the carrier layers along selected secondary attachment regions and provides a substantially water-insensitive connection therebetween. The secondary attachment regions are substantially restricted to locations spaced from the pocket regions.
