Title
(EN) AN ABSORBENT ARTICLE COMPRISING A LIQUID TRANSFER LAYER
(FR) ARTICLE ABSORBANT COMPRENANT UNE COUCHE DE TRANSFERT DE LIQUIDES
Abstract
(EN)
absorbent article comprising a liquid transfer layer (5) positioned between a liquid pervious bodyside liner (6) and an absorbent core (2). The liner (6) comprises a plurality of perforations (7). The liner and the transfer layer are bonded together in a plurality of bonding sites (11) covering an area of between 0.5% and 11 % of the area of the liner (6) that is circumscribed by the bonding sites and wherein each bonding site has an area of no more than 13 mm2. The combined perforated liner (6) and transfer layer (5) provides a quick inlet of liquid and a low rewet against the wearer. The liner (6) has a three- dimensional structure of alternating raised and depressed regions and the perforations (7) are present in the bottoms of the depressions (8) of said liner as seen from the body facing side of the liner.
(FR)
Cette invention se rapporte à un article absorbant comprenant une couche de transfert de liquides (5) positionnée entre une doublure intérieure perméable aux liquides (6) et un coeur absorbant (2). La doublure (6) comprend une pluralité de perforations (7). La doublure et la couche de transfert sont attachées ensemble au niveau d’une pluralité de points d’adhérence (11), couvrant une zone représentant de 0,05 % à 11 % de la zone de la doublure (6) qui est circonscrite par les points d’adhérence et dans laquelle chaque point d’adhérence a une zone ne dépassant pas 13 mm2. La doublure perforée (6) et la couche de transfert (5) combinées fournissent un orifice d’entrée rapide du liquide et une faible réhumidification contre l’utilisateur. La doublure (6) possède une structure tridimensionnelle alternant des zones en creux et en bosses et les perforations (7) sont présentes dans la partie inférieure des creux (8) de ladite doublure ainsi qu’observées sur le côté faisant face au corps de la doublure.
