The present invention relates to an absorbent multilayer material (9) that includes a perforated layer (4') of hydrophobic material and at least one layer (5') of absorbent material. According to the invention, mutually sequential rows of depressions (13) are disposed over that side of the multilayer material (9) which includes the hydrophobic layer (4'), wherein the depressions have the form of hammock-like parts of the hydrophobic layer that penetrate down into the layer of absorbent material (5') so as to form openings (14) perpendicular to the plane of the hydrophobic layer, wherein the hammock-like parts are fastened to the absorbent layer over the major part of their respective surfaces, and the absorbent layer is compressed within the region of each depression. The invention also relates to a method and to an arrangement for producing such material. |
