A disposable absorbent product (10) that comprises a liquid permeable top sheet (14); a liquid impermeable back sheet (12); and a two phase absorbent panel (16) positioned between the top sheet and the back sheet provided. The two phase absorbent panel structure comprises a wood pulp fiber and a surface cross linked superabsorbent material. In at least one layer of the two phase absorbent matrix, the superabsorbent material comprises substantially a continuous phase of the matrix (21'), where a sufficient quantity of particles of the superabsorbent material are in contact with each other to thereby define a capillary network for facilitating liquid transport within the matrix.

Produit absorbant jetable (10) comprenant une feuille supérieure perméable au liquide (14); une feuille arrière imperméable au liquide (12) et un panneau absorbant à deux phases (16) positionné entre la feuille supérieure et la feuille arrière. La structure du panneau absorbant comprend un matériau en fibres de pâte de bois et un matériau superabsorbant réticulé en surface. Dans au moins une couche de la matrice absorbante à deux phases, le matériau superabsorbant comprend une phase sensiblement continue de la matrice (21'), dans laquelle des quantités suffisantes de particules de matériau superabsorbant sont mutuellement en contact de manière à définir un réseau capillaire facilitant la circulation du liquide à l'intérieur de la matrice.
