(FR) MATIÈRES NON TISSÉES TRIDIMENSIONNELLES ET LEURS PROCÉDÉS DE FABRICATION
Abstract
(EN)
Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. In one embodiment, a nonwoven material comprising a plurality of fibers may comprise a first surface and a second surface, the first surface being opposite from the second surface, and an apertured zone. The apertured zone may comprise 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 providing a percent open area for the apertured zone of the nonwoven material from about 10% to about 60%, as determined by the Material Sample Analysis Test Method.
(FR)
L'invention concerne des matières non tissées tridimensionnelles et des procédés de fabrication de telles matières. Selon un mode de réalisation, une matière non tissée comprenant une pluralité de fibres peut comprendre une première surface et une seconde surface, la première surface étant opposée à la seconde surface, et une zone à ouvertures. La zone à ouvertures peut comprendre une pluralité de nœuds s'étendant loin d'un plan de base sur la première surface, une pluralité de ligaments de liaison reliant entre eux la pluralité de nœuds, une majorité de la pluralité de nœuds comprenant au moins trois ligaments de liaison reliés à des nœuds adjacents, et une pluralité d'ouvertures fournissant un pourcentage de zone ouverte pour la zone à ouvertures de la matière non tissée d'environ 10 % à environ 60 %, telle que déterminée par le procédé de test d'analyse d'échantillon de matière.
