Title (EN) DISPOSABLE ABSORBENT ARTICLE EMPLOYING AN ABSORBENT COMPOSITE, AND METHOD OF MAKING THE SAME
(FR) ARTICLE ABSORBANT JETABLE UTILISANT UN COMPOSITE ABSORBANT ET PROCEDE DE FABRICATION ASSOCIE
Abstract: front page image
(EN)A disposable absorbent article includes a topsheet (50), a backsheet (60) and an absorbent core (46) disposed therebetween. One or more of the backsheet, topsheet and absorbent core is constructed of an absorbent composite that includes an absorbent layer of hydratable fine fibers in the form of microfibril obtained from cellulose or a derivative thereof and super absorbent polymer (SAP) particles bonded together by the hydratable fibers and a nonwoven substrate supporting the absorbent layer such as SMS. The core may include one uniform layer of the absorbent composite or a composite having one layer of the nonwoven substrate and a plurality of segmented absorbent layers applied thereon. In the latter design, the absorbent layers are spaced apart from one another to expose surface sections of the substrate. These non-coated surface sections provide wicking zones which allow room for the absorbent layers to expand and prevent gel blocking.
(FR)L'invention concerne un article absorbant jetable comportant une couche supérieure, une couche arrière et un noyau absorbant disposé entre ces deux couches. Au moins un de ces éléments est constitué d'un composite absorbant qui comporte une couche absorbante de fibres fines hydratables sous forme de microfibrille obtenue à partir de cellulose ou de dérivés et des particules polymères superabsorbantes (SAP) liées par les fibres hydratables, et un substrat non tissé supportant la couche absorbante telle que le SMS (filé-lié/fusionné-soufflé/filé-lié). Cette couche absorbante est appliquée sur la surface du substrat non tissé. Le noyau peut comporter une couche uniforme dudit composite absorbant ou d'un composite constitué d'une couche du substrat non tissé et d'une pluralité de couches absorbantes segmentées appliquées sur ce substrat. Dans cette dernière conception, les couches absorbantes sont espacées entre elles de manière qu'elle laissent apparaître des parties de la surface du substrat. Ces parties de surface non revêtues constituent des zones mèche qui permettent l'expansion de la place destinée aux couches absorbantes et qui empêchent un blocage dû au gel.
