Abstract
La présente invention se rapporte à des stratifiés ondulés ayant des différentiels de densité créés dans un moins une des couches du stratifié. Les stratifiés (10) comportent une première couche (12) liée à une seconde couche (14) pour former un composite qui comprend une pluralité d'ondulations formant une série de pics séparée par une série de vallées. La seconde couche au moins est formée à partir d'un matériau compressible tel qu'une bande de non-tissé fibreux ayant formé à l'intérieur de cette couche des zones de densité différentes dues au procédé de fabrication utilisé pour former le stratifié. Dans un procédé, la première et la seconde couche sont liées l'une à l'autre le long d'une série de lignes de liaison (16) généralement parallèles tandis que l'un au moins des matériaux est tendu. Une fois la liaison achevée, la tension est relâchée et le stratifié forme une série d'ondulations. Dans les zones de vallée (18) immédiatement adjacentes aux lignes de liaison, le stratifié et notamment la seconde couche ont une densité accrue du fait du procédé de liaison. Dans les zones de pic (20), qui se trouvent entre les vallées, le stratifié et notamment la seconde couche, ont une densité plus faible. Il en résulte que des fluides pénétrant dans le stratifié par la première couche ont tendance à être attirés vers les zones les plus denses adjacentes aux lignes de liaison. Si l'on combine cette particularité avec la zone de contact de surface réduite de la première couche due aux ondulations, le matériau se trouve être particulièrement adapté à être utilisé en tant que revêtement côté corps pour des articles absorbants de soins personnels.
