Title (EN) ABSORBENT PRODUCT COMPRISING INLET MATERIAL
(FR) PRODUIT ABSORBANT COMPRENANT UN MATÉRIAU D'ENTRÉE
Abstract:
(EN) Absorbent product comprising a liquid pervious topsheet, a liquid impervious backsheet and an absorbent core enclosed between the liquid pervious topsheet and liquid impervious backsheet. The absorbent product has in its longitudinal direction a crotch part and two end parts. The absorbent product comprises at least in its crotch part an inlet material having a plurality of openings. The plurality of openings in the inlet material are formed from a plurality of slits extending in the transversal direction of the absorbent product and that openings have been formed from the slits by expanding the continuous inlet material in the longitudinal direction of the absorbent product. The liquid inlet material has in its transversal direction of the absorbent product a central region and two edge regions. The openings are located in the central region so that the central region of the material with the plurality of openings has a lesser degree of elasticity than the edge regions.
(FR) L'invention concerne un produit absorbant comprenant une feuille supérieure perméable aux liquides, une feuille arrière imperméable aux liquides et un noyau absorbant enfermé entre la feuille supérieure perméable aux liquides et la feuille arrière imperméable aux liquides. Le produit absorbant comprend dans sa direction longitudinale une partie d'entrejambe et deux parties d'extrémité. Le produit absorbant comprend au moins dans sa partie d'entrejambe un matériau d'entrée comportant une pluralité d'ouvertures. La pluralité d'ouvertures dans le matériau d'entrée est formée à partir d'une pluralité de fentes s'étendant dans la direction transversale du produit absorbant et ces ouvertures ont été formées à partir des fentes par expansion du matériau d'entrée continu dans la direction longitudinale du produit absorbant. Le matériau d'entrée de liquide comporte dans sa direction transversale du produit absorbant une région centrale et deux régions de bord. Les ouvertures sont situées dans la région centrale de telle sorte que la région centrale du matériau avec la pluralité d'ouvertures a un degré d'élasticité inférieur à celui des régions de bord.
