Patent

CA 2183237

The present invention provides a three-dimensional, macroscopically expanded, apertured, laminate web suitable for use as a topsheet on an absorbent article and a method for making the same. The web includes a first layer of substantially transparent, polymeric material having an inner surface and an outer surface. A nonwoven web is secured to the inner surface of the substantially transparent polymeric material and is visible through the substantially transparent polymeric material. The presence of the nonwoven web creates the appearance of a fibrous web which is perceived as soft and skin friendly while still maintaining the fluid transport benefits of prior art plastic webs.

La présente invention se rapporte à une bande stratifiée, ajourée, à expansion macroscopique, tridimensionnelle, appropriée pour être utilisée comme une feuille de couverture d'un article absorbant, et à son procédé de fabrication. La bande comprend une première couche de matériau polymère, pratiquement transparent, comportant une surface interne et une surface externe. Une bande non tissée est fixée sur la surface interne du matériau polymère pratiquement transparent, et peut être vue par le matériau polymère pratiquement transparent. La présence de la bande non tissée crée l'apparence d'une bande fibreuse qui est perçue comme étant souple et agréable à porter, tout en conservant les avantages de l'acheminement du fluide des bandes en plastique de la technique antérieure.
