Title
(EN) THREE-DIMENSIONAL NONWOVEN MATERIALS AND METHODS OF MANUFACTURING THEREOF
(FR) MATÉRIAUX NON TISSÉS TRIDIMENSIONNELS 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 may comprise a plurality of fibers and may further comprise an opposing first surface and a second surface, 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, and a plurality of openings providing a percent open area for the apertured zone that is greater than about 15%, as determined by the Material Sample Analysis Test Method. The material may further comprise a first and second side zones with the nonwoven material having a material width and the first and second side zones having first and second side zone widths, and wherein each of the first and second side zone widths are between about 5% and about 25% of the nonwoven material width.

L'invention concerne des matériaux non tissés tridimensionnels et leurs procédés de fabrication. Dans un mode de réalisation, un matériau non tissé peut comprendre une pluralité de fibres et peut en outre comprendre une première surface opposée et une seconde surface, une zone ajourée 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, et une pluralité d'ouvertures fournissant un pourcentage d'espace ouvert pour la zone ajourée qui est supérieur à environ 15 %, tel que déterminé par le procédé de test d'analyse d'échantillon de matériau. Le matériau peut en outre comprendre une première et une seconde zone latérale, le matériau non tissé étant d'une certaine largeur et les première et deuxième zones latérales étant d'une certaine largeur, et dans lequel chacune des première et deuxième largeurs de zones latérales est comprise entre environ 5 % et environ 25 % de la largeur du matériau non tissé.
