Title
(EN) ABSORBENT STRUCTURE
(FR) STRUCTURE ABSORBANTE
Abstract
(EN)
The invention relates to an absorbent structure (3) for use in an absorbent article (1) and being defined by an airlaid material structure (3) being formed by a plurality of layers (3a; 3b; 3c; 3d) which are interposed between a liquid- permeable top sheet (2) and an absorbent core (4), said absorbent article (1) also comprising a backsheet (5) being of liquid-impermeable material. According to the invention, the absorbent structure (3) comprises a first layer (3a) having resilient synthetic fibers of at least approximately 5 dtex; that the absorbent structure (3) comprises a second layer (3b) having superabsorbent particles generally arranged as a distinct layer as opposed to being integrated within any other material of said absorbent structure (3); and that the absorbent structure (3) also comprises a treated fluff material having hydrophilic properties.
(FR)
L'invention concerne une structure absorbante (3) qui est destinée à être utilisée dans un article absorbant (1) et qui est définie par une structure de matériau déposé par jet d'air (3) formée par une pluralité de couches (3a; 3b; 3c; 3d) elles-mêmes interposées entre une feuille supérieure perméable aux liquides (2) et une âme absorbante (4), l'article absorbant (1) comprenant également une feuille arrière (5) réalisée dans un matériau imperméable aux liquides. Selon la présente invention, la structure absorbante (3) comprend une première couche (3a) ayant des fibres synthétiques résilientes d'au moins environ 5 dtex; la structure absorbante (3) comprend une seconde couche (3b) ayant des particules super absorbantes qui sont généralement agencées sous forme d'une couche distincte plutôt que d'être intégrées dans n'importe quel autre matériau de la structure absorbante (3); et la structure absorbante (3) comprend également un matériau pelucheux traité ayant des propriétés hydrophiles.
