CA 2668868

A composite sheet which has a low basis weight, can be prevented from breaking during the production of an absorbent article or in use, and is good to the touch. The composite sheet (1) is a sheet formed by bonding a stretch nonwoven fabric (2) to a nonstretch nonwoven fabric (3) with an adhesive (4). The stretch nonwoven fabric (2) is bonded in a stretched state to the nonstretch sheet. The stretch nonwoven fabric (2) has, on each side, strip-form sparse regions (21) and strip-form dense regions (22) alternately formed. The sparse regions (21) and dense regions (22) on one side are alternately formed in a second direction so that the dense regions (22) on this side do not overlie the dense regions (22) on the other side. The composite sheet (1) has a maximum breaking strength of 20 N/50 mm or higher.

L'invention concerne une feuille composite de faible masse surfacique, qui peut être protégée contre la rupture pendant la production d'un article absorbant ou en cours d'utilisation, et qui est agréable au toucher. Cette feuille composite (1) est formée par liaison d'un tissu nontissé extensible (2) à un tissu nontissé non extensible (3) au moyen d'un adhésif (4). Le tissu nontissé extensible (2) est lié de manière extensible à la feuille non extensible. Le tissu nontissé extensible (2) comprend, sur chaque côté, une alternance de régions de faible densité (21) formant des bandes et de régions denses (22) formant des bandes. Les régions de faible densité (21) et les régions denses (22) sur un côté sont formées par alternance dans un deuxième sens de façon que les régions denses (22) sur ce même côté ne recouvrent pas les régions denses (22) sur l'autre côté. La feuille composite (1) présente une résistance à la rupture maximale supérieure ou égale à 20 N/50 mm.
