Title
(EN) THREE-DIMENSIONAL NONWOVEN MATERIALS AND METHODS OF MANUFACTURING THEREOF
(FR) MATÉRIAUX NON TISSÉS TRIDIMENSIONNELS ET PROCÉDÉS DE FABRICATION DE CEUX-CI
Abstract
(EN)
Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. In one embodiment, a nonwoven material may comprise a plurality of fibers, a first surface, and an apertured zone comprising: a plurality of nodes extending away from a base plane on the first surface, a plurality of connecting ligaments interconnecting the plurality of nodes, wherein a majority of the plurality of nodes include at least three connecting ligaments connecting to adjacent nodes, and a plurality of openings. The apertured zone may further comprise a lane of nodes which extends substantially in the longitudinal direction, and wherein the lane of nodes extending substantially in the longitudinal direction is formed of longitudinally adjacent nodes which are aligned such that lines drawn between centers of longitudinally adjacent nodes within the lane of nodes each form an angle with respect to the longitudinal direction of less than about 20 degrees.

La présente invention concerne des matériaux non tissés tridimensionnels et des procédés de fabrication de tels matériaux. Dans un mode de réalisation, un matériau non tissé peut comprendre une pluralité de fibres, une première surface, et une zone perforée comprenant : une pluralité de nœuds s’étendant à l’opposé d’un plan de base sur la première surface, une pluralité de ligaments de connexion interconnectant la pluralité de nœuds, une majorité de la pluralité de nœuds comprenant au moins trois ligaments de connexion se connectant à des nœuds adjacents, et une pluralité d’ouvertures. La zone perforée peut comprendre en outre une rangée de nœuds qui s’étend sensiblement dans la direction longitudinale, et la rangée de nœuds s’étendant sensiblement dans la direction longitudinale étant formée de nœuds longitudinalement adjacents qui sont alignés de sorte que des lignes tracées entre les centres de nœuds longitudinalement adjacents à l’intérieur de la rangée de nœuds forment chacune un angle par rapport à la direction longitudinale inférieur à environ 20 degrés.
