Abstract

Disclosed is a thin, layered, absorbent structure comprising first and second layers of fibrous material and an intermediate layer comprising particles of a hydrogelling, absorbent material, in an amount exceeding 120 g/m.sup.2, and particles of a thermoplastic, polymeric, organic material; the first and second fibrous layers extend beyond the intermediate layer laterally to form longitudinal edge portions. The two fibrous layers are bound together with the intermediate layer between them by the melting of the particles of thermoplastic, polymeric, organic material and by means of a continuous line of adhesive extending longitudinally on each longitudinal edge portion.
