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 method can include providing a precursor web that includes a plurality of fibers and transferring the precursor web to a forming surface having a plurality of forming holes. The method can also include directing a plurality of pressurized fluid streams of entangling fluid in a direction towards the precursor web on the forming surface to move at least some of the fibers into the plurality of forming holes to create a fluid entangled web. The method can further include removing the fluid entangled web from the forming surface such that the at least some of the fibers moved into the plurality of forming holes provide a plurality of nodes. The plurality of nodes can have an anisotropy value greater than 1.0 as determined by the Node Analysis Test Method.

L'invention concerne des matériaux non tissés tridimensionnels et des procédés de fabrication de tels matériaux. Dans un mode de réalisation, un procédé peut consister à utiliser une bande précurseur qui comprend une pluralité de fibres et à transférer la bande précurseur vers une surface de formation comprenant une pluralité de trous de formation. Le procédé peut également consister à diriger une pluralité de flux de fluide sous pression de fluide emmêlant dans une direction vers la bande précurseur sur la surface de formation pour déplacer au moins certaines des fibres dans la pluralité de trous de formation pour créer une bande emmêlée par fluide. Le procédé peut en outre consister à retirer la bande emmêlée par fluide de la surface de formation de sorte que ladite au moins une partie des fibres déplacées dans la pluralité de trous de formation fournisse une pluralité de nœuds. La pluralité de nœuds peut présenter une valeur d'anisotropie supérieure à 1,0 telle que déterminée par le procédé de test d'analyse de nœuds.
