Abstract
The present invention relates to an absorbent core for sanitary products with an absorption matrix which comprises a high proportion of super-absorbing particles, and an absorbent core cover for enveloping the absorption matrix, wherein the absorbent core cover comprises at least one upper side sheet and one bottom side sheet, and the absorbent core cover comprises at least one connection region spaced apart from the edge of the absorbent core in which the upper side sheet and the bottom side sheet are connected to each other. Here, at least the upper side sheet of the absorbent core cover is embodied as a fleece composite with a fixing layer with a low permeability to retain the particles in the absorption matrix, and a transfer layer for acquiring fluid. Moreover, the invention relates to a sanitary product having such an absorbent core, the use of a fleece composite as an absorbent core cover, and a method for manufacturing a fleece composite for the upper side sheet of the absorbent core cover.
