A disposable absorbent product (20) such as, e.g. a baby diaper, an adult incontinence pad, a sanitary napkin or the like, includes a liquid pervious topsheet (24), a liquid impervious backsheet (26), and an absorbent core (28) positioned between the topsheet (24) and the backsheet (26). The absorbent core (28) has a liquid receiving surface directed towards said topsheet (24), and the absorbent core (28) is provided with at least one embossing (50) forming a channel for liquid drainage at said receiving surface. Preferably an acquisition layer (40) is provided between the topsheet (24) and the absorbent core (28). The acquisition layer preferably extends into the embossing (50), while a resilient absorbent member (30) is preferably provided between the absorbent core (28) and the acquisition layer (40) in the form of stripes arranged longitudinally spaced along the upper longitudinal sides of the channel (50) formed by the embossing.

L'invention concerne un produit absorbant jetable (20), tel que par ex., une couche pour bébé, une serviette pour adulte incontinent, une serviette hygiénique ou similaire, qui comprend une couche supérieure perméable aux liquides, une couche de fond imperméable aux liquides (26) et un noyau absorbant (28), positionné entre la couche supérieur (24) et la couche de fond (26). Le noyau absorbant (28) comprend une surface de réception de liquides, dirigée vers la couche supérieure (24) et ledit noyau absorbant (28) est muni d'au moins une partie bosselée (50) formant un canal pour le drainage des liquides au niveau de la surface de réception. De préférence, une couche d'acquisition(40) est prévue entre la couche supérieure (24) et le noyau absorbant (28). La couche d'acquisition s'étend de préférence dans la partie gaufrée (50), alors que l'élément absorbant résilient (30) est prévu de préférence entre le noyau absorbant (28) et la couche d'acquisition, sous la forme de bandes disposées longitudinalement, de manière espacée, le long des côtés longitudinaux supérieurs du canal (50) formé par la partie gaufrée.
