Patent

CA 2159073

The present invention provides a resilient, fluid-pervious, laminate, plastic web suitable for use as a topsheet on absorbent articles, especially catamenial articles. The web includes a first layer of polymeric material, a second layer of polymeric material and an intermediate layer of fibrous material. The fibrous material of the intermediate layer extends below the second surface of the web, preferably into the absorbent core. In-use, fluid deposited on the topsheet drains or empties more readily as the fibrous material of the intermediate layer breaks up the fluid meniscuses which form along the second surface of the web, thereby providing improved dryness and cleanliness for the user.

Voile en plastique stratifié souple et perméable au liquide utilisable comme feuille supérieure d'articles absorbants, notamment à usage cataménial. Le voile comporte une première couche de polymère, une seconde couche de polymère et une couche intermédiaire de matière fibreuse. La matière fibreuse de la couche intermédiaire s'étend sous la deuxième surface du voile, de préférence jusqu'à l'intérieur de l'âme absorbante. Le liquide déposé sur la feuille supérieure est plus facilement drainé ou évacué car la matière fibreuse de la couche intermédiaire rompt le ménisque du fluide se formant sur la deuxième surface du voile, ce qui assure à l'usager une meilleure siccite et une meilleure propreté.
