    摘要： The present invention is an absorbent core that may be incorporated into absorbent hygiene articles, such as baby diapers, adult incontinence or feminine hygiene articles. It is particularly suited for articles which are intended to receive more than one liquid gush load, as the absorbent core comprises a fluid distribution layer that comprises sub-layers comprising particular ratios of multicomponent binder fibers, cross-linked cellulose fiber and/or treated or untreated cellulosic fibers.

    摘要： The present invention relates to an absorbent structure with a sequence of two layers comprising at least one liquid absorption layer, a subsequent liquid storage layer with super absorbent polymer SAP, preferably SAP particles and/or SAP fibers and a subsequent liquid distribution layer, wherein the layers are connected and form a sheet structure, wherein at least the liquid storage layer and the liquid distribution layer each at least have an air laid material, preferably an air laid ply comprising cellulose fibers as main constituent, an area of the air laid material in the liquid distribution layer being more narrowly pored than an area of the air laid material in the liquid storage layer, and wherein the liquid storage layer has super absorbent polymer, in particular SAP particles, extending from the liquid storage layer into the liquid distribution layer in order to generate a return suction effect for the liquid that has passed through the liquid absorbent layer and liquid storage layer into the liquid distribution layer.
