Abstract

An absorbent core for use in an absorbent article, the absorbent core including a first absorbent layer comprising a first substrate, a layer of first superabsorbent polymer particles deposited on the first substrate on a deposition area and a fibrous layer of thermoplastic adhesive material covering the layer of first superabsorbent polymer particles, and a second absorbent layer comprising a second substrate and a mixed layer comprising a mixture of second superabsorbent particles and cellulosic fibers deposited on the second substrate. The first and second absorbent layers are combined together such that at least a portion of the fibrous thermoplastic adhesive material of the first absorbent layer contacts at least a portion of the mixed layer of the second absorbent layer.
