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. An absorbent article can include an absorbent body and an outer cover. The absorbent article can also include a fluid-entangled nonwoven material. The absorbent body can be disposed between the fluid-entangled nonwoven material and the outer cover. The fluid-entangled nonwoven can include a first surface and a second surface. The nonwoven material can also include a plurality of nodes extending away from a base plane on the first surface towards the absorbent body. The nonwoven material can further include a plurality of openings extending from the first surface to the second surface through the fluid-entangled nonwoven material. Individual openings of the plurality of openings can be disposed between adjacent nodes of the plurality of nodes.

La présente invention concerne des matériaux non-tissés tridimensionnels et des procédés de fabrication de tels matériaux. Un article absorbant peut comprendre un corps absorbant et un revêtement externe. L’article absorbant peut également comprendre un matériau non-tissé enchevêtré dans du liquide. Le corps absorbant peut être disposé entre le matériau non-tissé enchevêtré dans du liquide et le revêtement externe. Le non-tissé enchevêtré dans du liquide peut comprendre une première surface et une seconde surface. Le matériau non-tissé peut également comprendre une pluralité de nœuds s’étendant loin d’un plan de base sur la première surface vers le corps absorbant. Le matériau non-tissé peut en outre comprendre une pluralité d’ouvertures s’étendant depuis la première surface vers la seconde surface à travers le matériau non-tissé enchevêtré dans du liquide. Des ouvertures individuelles de la pluralité d’ouvertures peuvent être disposées entre des nœuds adjacents de la pluralité de nœuds.
