(FR) MATÉRIAUX NON TISSÉS TRIDIMENSIONNELS ET LEURS PROCÉDÉS DE FABRICATION
Abstract
(EN)
Three dimensional nonwoven materials and absorbent articles comprising such materials are disclosed. In one embodiment, an absorbent article may comprise an outer cover, a bodyside liner, an absorbent body, and a nonwoven material coupled to the bodyside liner. The nonwoven material may comprise an apertured zone providing a percent open area for the apertured zone that is greater than about 15%. The nonwoven material may be coupled to liner by a front waist bond forming a front waist bonding region which extends through the apertured zone and a rear waist bond forming a rear waist bonding region, wherein the rear waist bonding region has a length that is between about 2% and about 10% of the material length and the front waist bonding region has a length that is between about 20% and about 50% of the material length.

Matériaux non tissés tridimensionnels et articles absorbants comprenant de tels matériaux. Selon un mode de réalisation, un article absorbant peut comprendre un revêtement extérieur, une doublure côté corps, un corps absorbant, et un matériau non tissé couplé à la doublure côté corps. Le matériau non tissé peut comprendre une zone à ouvertures fournissant un pourcentage de zone ouverte pour la zone à ouvertures qui est supérieur à environ 15 %. Le matériau non tissé peut être couplé à la doublure par une liaison de taille avant formant une région de liaison de taille avant qui s'étend à travers la zone à ouvertures et une liaison de taille arrière formant une région de liaison de taille arrière, la région de liaison de taille arrière ayant une longueur qui est comprise entre environ 2 % et environ 10 % de la longueur de matériau et la région de liaison de taille avant ayant une longueur qui est comprise entre environ 20 % et environ 50 % de la longueur de matériau.
