Abstract

La présente invention concerne une couche jetable dont le panneau absorbant ne montre pas de perte d'absorption, ladite couche étant caractérisée par une migration rapide des liquides organiques en direction du panneau absorbant. Une couche (1) comporte un voile intérieur perméable aux liquides (20), un voile extérieur imperméable aux liquides (30), un panneau absorbant capable d'absorber les liquides (40) et positionné entre les voiles intérieur et extérieur (20, 30) et un voile anti-fuites (50) positionné entre le panneau absorbant (40) et le voile extérieur (30). Une paire de voiles occlusifs (60), espacés l'un de l'autre dans le sens latéral (X), est présente à la surface située côté peau du voile intérieur (20). Le panneau absorbant (40) comporte un matériau noyau absorbant le liquide (41) et un voile de revêtement (42), par exemple en papier mince, recouvrant ledit matériau noyau (41). Une pluralité de concavités (45) orientées vers une surface absorbante (43) depuis une surface inférieure (44) est présente au niveau du panneau absorbant (40). La surface d'absorption (43) ne comporte aucune concavité (45) et est essentiellement de niveau. Des première, deuxième, troisième et quatrième concavités de compression (71 à 74) et une pluralité de parties en relief (26) et en creux (27) sont présentes à la surface (25) du voile intérieur (20).
