Absorbent structures and nuclei efficient immobilization of absorbent material

An absorbent structure (70) comprising: - a substrate (16) substantially plane extending in a transverse direction (x) and a longitudinal direction (y), - an auxiliary adhesive (72) applied directly on the substrate (16) an area (71) of application of auxiliary glue, - an absorbent material comprising from 80% to 100% by weight of superabsorbent polymer particles deposited on the substrate over an area (73) deposition of absorbent material comprising a design areas (75) placement of absorbent material separated by areas (76) of free binding of absorbent material, wherein the area of ​​deposition of absorbent material can be divided theoretically into eight zones (Z1-Z8) deposition of equal length along the longitudinal direction; and - a layer (74) adhesive fibrous thermoplastic covering at least some of the placement areas and at least some of the areas of free binding absorbent material to immobilize thereby at least some absorbent material on the substrate; wherein an amount of the absorbent material along the longitudinal direction of the structure, so that at least one of the eight zones of deposition is an area of ​​lesser amount (Z1, Z2, Z7, Z8) of material is outlined absorbent having an amount of absorbent material is at least 20% in less than average amount of absorbent material in the eight zones of deposition and the auxiliary adhesive (72) weight is absent or present at a level of at least 50 % in less than average amount of auxiliary glue in the eight zones of deposition weight in at least one of these zones (Z1, Z2, Z7, Z8) of a smaller amount of absorbent material.
