In an absorbent article (10) including an absorbent structure (32) positioned between the top sheet (12) and the back sheet (14), the absorbent structure (32) includes an upper layer (28), a lower layer (30), and an elongate, absorbent core (40), which is formed from cellulosic fibers and from distributed particles of a super-absorbent polymer (SAP), and which has an elongate, central portion (40) with an absorbency under load (AUL) not less than about 12 grams/gram. Having a basis weight not more than about 150 grams per square meter and an absorbency under load (AUL) not more than about 6 grams/gram, the lower layer (30) has a minimal absorbency but is capable of transferring to a lower surface of the absorbent core (32) a liquid permeating the lower layer (30) from the absorbent core (32).
L'invention concerne un article (10) absorbant comprenant une structure (32) absorbante disposée entre la couche supérieure (12) et la couche arrière (14), la structure (32) absorbante comprenant une couche supérieure (28), une couche inférieure (30), et une âme (40) allongée et absorbante, formée de fibres cellulosiques et de particules réparties d'un polymère super-absorbant (SAP), et dotée d'une partie centrale (40) allongée possédant un pouvoir absorbant sous charge (AUL) non inférieur à 12 grammes/gramme environ. Avec un poids de base ne dépassant pas 150 grammes par mètre carré environ, et un pouvoir absorbant sous charge (AUL) ne dépassant pas 6 grammes/gramme environ, la couche inférieure (30) possède pouvoir absorbant minimal, mais peut transférer dans une couche inférieure de l'âme absorbante (32), un liquide imprégnant la couche inférieure (30) et provenant de l'âme absorbante (32).
