Abstract
An absorbent core for use in an absorbent article, having a central fibrous layer having synthetic fibers, and a three-dimensional sub-layer having a plurality of small pockets that contain superabsorbent particles. Superabsorbent particles are deposited and partially enclosed in the discrete small pockets, and are prevented from shifting to other portions of the absorbent core. An absorbent article including the absorbent core, and a method for providing an absorbent article including the absorbent core are also described.
