Title
(EN) ABSORBENT ARTICLE WITH IMPROVED CORE AND METHOD OF MAKING
(FR) ARTICLE ABSORBANT À PARTIE CENTRALE AMÉLIORÉE ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN) An absorbent article comprising: a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core positioned between said topsheet and backsheet, wherein the absorbent core comprises an absorbent material, said absorbent material comprising cellulose fibers and/or superabsorbent polymers, and wherein said absorbent material is contained within at least one core wrap substrate enclosing said absorbent material therein, wherein the absorbent core further comprises an intermediate layer positioned between a top layer of said core wrap and a bottom layer of said core wrap such that said absorbent material is disposed between said top layer and said intermediate layer and between said bottom layer and said intermediate layer.
(FR) L'invention concerne un article absorbant comprenant : une feuille supérieure perméable aux liquides, une feuille arrière imperméable aux liquides et une partie centrale absorbante positionnée entre lesdites feuille supérieure et feuille arrière, la partie centrale absorbante comprenant un matériau absorbant, ledit matériau absorbant comprenant des fibres de cellulose et/ou des polymères superabsorbants, et ledit matériau absorbant étant contenu à l'intérieur d'au moins un substrat d'enveloppe de partie centrale renfermant ledit matériau absorbant en son sein, la partie centrale absorbante comprenant en outre une couche intermédiaire positionnée entre une couche supérieure de ladite enveloppe de partie centrale et une couche inférieure de ladite enveloppe de partie centrale de sorte que ledit matériau absorbant est disposé entre ladite couche supérieure et ladite couche intermédiaire et entre ladite couche inférieure et ladite couche intermédiaire.
