Abstract

L'invention concerne une structure unitaire absorbante (10), laquelle comporte une couche fibreuse supérieure (12) ayant une zone d'acquisition de liquide (2) qui s'étend vers une surface, et une zone de distribution de liquide (4) qui s'étend vers l'autre surface. Une couche fibreuse inférieure de stockage de liquide (14) est en communication avec la surface de la zone de distribution de la couche supérieure, aux fins d'échange de liquide. La couche de stockage renferme des particules polymères ultra-absorbantes (18). Une couche de retenue (8) entoure la couche de stockage, s'étendant vers les bords extérieurs de la structure. La couche de retenue retient les fibres (6) et les particules polymères ultra-absorbantes de la couche de stockage contre la surface de la zone de distribution de la couche supérieure.
