摘要：
An absorbent structure (70) comprising a substantially planar substrate (16), an auxiliary glue (72) applied directly over the substrate (16) on an auxiliary glue application area (71), an absorbent material comprising from 80% to 100% by weight of superabsorbent particles deposited on the substrate on an absorbent material deposition area (73) comprising a pattern of absorbent material land areas (75) separated by absorbent material-free junction areas (76), wherein the absorbent material deposition area can be notionally divided in eight deposition zones (Z1-Z8) of equal length along the longitudinal direction. A fibrous thermoplastic adhesive layer (74) covers at least some of the land areas and at least some of the absorbent material-free junction areas to thereby immobilize at least some of the absorbent material on the substrate. The absorbent material is profiled along the longitudinal direction of the structure so that at least one of the eight deposition zones is a zone of lower absorbent material amount (Z1, Z2, Z7, Z8) and the auxiliary glue (71) is absent, or present at a level of at least 50% by weight lower than the average amount of auxiliary glue in at least one of these zones (Z1, Z2, Z7, Z8) of lower absorbent material amount. The absorbent structure can be made in an absorbent core for absorbent articles such as diapers.La présente invention concerne une structure absorbante (70) comprenant un substrat sensiblement plan (16), une colle auxiliaire (72) directement appliquée sur le substrat (16) sur une zone d'application de colle auxiliaire (71), un matériau absorbant comprenant de 80 % à 100 % en poids de particules superabsorbantes déposées sur le substrat sur une zone de dépôt de matériau absorbant (73) comprenant un motif de zones de dépôt de matériau absorbant (75) séparées par des zones de jonction sans matériau absorbant (76), la zone de dépôt de matériau absorbant pouvant être théoriquement divisée en huit zones de dépôt (Z1-Z8) de longueur
