CA 2757892

A stretchable laminate, a process of making a stretchable laminate and a disposable absorbent article that includes a stretchable laminate are disclosed. The stretchable laminate includes a nonwoven web and a web of elastomeric material. The nonwoven web includes two layers of spunbond multi-component fibers and one layer of meltblown fibers. The multi-component fibers include a first polymer and a second polymer having different melt temperatures. Thermo-bonds are formed at least partially through the nonwoven web. Some of the thermo-bonds can be elongated in the cross-machine direction of the nonwoven web.

L'invention porte sur un stratifié étirable, sur un procédé de fabrication d'un stratifié étirable et sur un article absorbant jetable qui comprend un stratifié étirable. Le stratifié étirable comprend une bande non tissée et une bande de matière élastomère. La bande non tissée comprend deux couches de fibres multi-composants filées-liées et une couche de fibres de fusion-soufflage. Les fibres multi-composants comprennent un premier polymère et un second polymère ayant différentes températures de matière fondue. Des thermo-liaisons sont formées au moins partiellement à travers la bande non tissée. Certaines des thermo-liaisons peuvent être allongées transversalement au sens de déplacement de la bande non tissée dans la machine.
