The invention relates to an absorbent structure (1) having a first layer which forms a mixture of absorbent gelling material particles (5), fibers, a second layer comprising liquid permeable substrate (7), and absorbent gelling material particles (9) attached to said substrate thus forming a laminate. The weight of the absorbent gelling material particles (5) in the mixed layer is not more than 70 percent, preferably not more than 60 percent of the weight of the mixed layer. The combined weight of the absorbent gelling material particles attached to the substrate (7), and in the mixed layer (5) is at least 80 percent, preferably at least 140 percent of the weight of fibers in the mixed layer (5). The laminate (7, 9) can be located on top of the mixed layer (5), and comprises an acquisition zone (15) of low basis weight of absorbent gelling material particles. The laminate may also be located below the mixed layer.

L'invention concerne une structure d'absorbant (1) ayant une première couche constituée d'un mélange de particules absorbantes de matériau formant gel (5) et de fibres et une seconde couche comprenant un substrat (7) perméable aux liquides et des particules absorbantes de matériau formant gel (9), fixées au substrat pour constituer un stratifié. Le poids des particules absorbantes de matériau formant gel (5) dans la couche mixte ne dépasse pas 70 pourcent et de préférence 60 pourcent du poids de la couche mixte. Le poids combiné des particules absorbantes de matériau formant gel fixées au substrat (7) et présentes dans la couche mixte (5) est égal au moins à 80 pourcent, de préférence au moins à 140 pourcent du poids des fibres de la couche mixte (5). Le stratifié (7, 9) peut se trouver sur la couche mixte (5) et comporter une zone d'absorption (15) à faible poids de base des particules absorbantes formant gel. Le stratifié peut également être placé sous la couche mixte.
