Title (EN) LOW BASIS WEIGHT NONWOVEN WEB WITH VISIBLY DISTINCT PATTERNS
(FR) BANDE NON TISSÉE DE FAIBLE MASSE SURFACIQUE PRÉSENTANT DES MOTIFS VISIBLEMENT DISTINCTS
Abstract:
(EN) The present invention relates to a SMS nonwoven laminate having a basis weight of less than about 20 gsm, said nonwoven laminate comprising outer layers of continuous spunbond filaments and an internal layer of from about 18% to about 43%, by weight of the nonwoven laminate of meltblown fibers, said nonwoven laminate having been hydroentangled to create visibly distinct patterns on the surface of at least one of the outer layers of said nonwoven laminate; and wherein prior to said hydroentangling, the content of meltblown fibers in the nonwoven laminate was from about 20% to about 45%, by weight of the nonwoven laminate.
(FR) L'invention concerne un stratifié non-tissé SMS présentant une masse surfacique inférieure à environ 20 g/m2, ledit stratifié non-tissé comportant des couches externes de filaments continus filés-liés et une couche interne d'environ 18% à environ 43% en poids du stratifié non-tissé de fibres obtenues par fusion-soufflage, ledit stratifié non-tissé ayant été hydroenchevêtré de manière à créer des motifs visiblement distincts sur la surface d'au moins une des couches externes dudit stratifié non tissé; et préalablement audit hydroenchevêtrement, la teneur dudit stratifié non-tissé en fibres obtenues pare fusion-soufflage ayant été d'environ 20% à environ 45% en poids du stratifié non-tissé.
