Abstract

An absorbent core for absorbent articles such as diapers comprising a core wrap comprising a top side and a bottom side, an absorbent material between the top side and the bottom side of the core wrap, a first and second longitudinally-extending channel-forming areas disposed on opposite sides of the longitudinal axis and substantially free of absorbent material preferably through which the top side of the core wrap is preferably attached to the bottom side of the core wrap. The core has a central absorbent zone between the first and the second channel-forming areas and a first and second lateral absorbent zones disposed laterally outwardly. The basis weight of the absorbent material in the central absorbent zone is higher than the basis weight of the absorbent material in each of the lateral absorbent zones for at least a first transversal section (S1). This relation is inverted along a second transversal section (S2) of the core. The first and second sections have each a length in the longitudinal direction of at least 10 mm.
