A thin, layered, absorbent structure comprises first and second layers (1, 2) of fibrous material and an intermediate layer (5) comprising particles of a hydrogelling, absorbent material (6), in an amount exceeding 120 g/m2, and particles of a thermoplastic, polymeric, organic material (7); the first and second fibrous layers (1, 2) extend beyond the intermediate layer (5) laterally to form longitudinal edge portions (8). The two fibrous layers (1, 2) are bound together with the intermediate layer (5) between them by the melting of the particles of thermoplastic, polymeric, organic material (7) and by means of a continuous line (10) of adhesive extending longitudinally on each longitudinal edge portion (8).

Une structure absorbante fine, multicouche, comprend une première et une seconde couches (1, 2) d'un matériau fibreux, ainsi qu'une couche intermédiaire (5) comportant des particules d'un matériau hydrogel absorbant (6), dans une quantité supérieure à 120 g/m?2?, ainsi que des particules d'un matériau organique (7) thermoplastique polymère; les première et seconde couches fibreuses (1, 2) s'étendent latéralement au-delà de la couche intermédiaire (5) pour former des bords longitudinaux (8). Les deux couches fibreuses (1, 2) sont liées ensemble avec la couche intermédiaire (5) par fusion des particules de matériau organique (7) thermoplastique polymère, et au moyen d'une ligne continue (10) d'adhésif s'étendant longitudinalement sur chaque bord longitudinal (8).
