Abstract

L'invention concerne une feuille pour un article absorbant ayant un équilibre amélioré entre une vitesse d'absorption de liquide, une propriété de prévention de retour de liquide et une propriété de prévention de rétention de liquide. La feuille pour un article absorbant est un tissu non tissé comprenant une première couche de fibres et une seconde couche de fibres positionnée sur une surface principale de la première couche de fibres. La première couche de fibres comprend une fibre synthétique (ci-après désignée par « fibre hydrofuge ») contenant un agent de traitement de fibres hydrofuges, et une fibre (ci-après désignée par « première fibre ») ayant un caractère hydrofuge inférieur à celui de la fibre hydrofuge. La seconde couche de fibres comprend une fibre (ci-après désignée par « seconde fibre ») ayant un caractère hydrofuge inférieur à celui de la fibre hydrofuge. Le diamètre de fibre de la fibre hydrofuge est de 23,5 à 42 µm. Le diamètre de fibre de la première fibre est inférieur au diamètre de fibre de la fibre hydrofuge. La proportion (% en masse) de la seconde fibre contenue dans la seconde couche de fibres est supérieure à la proportion (% en masse) de la fibre hydrofuge contenue dans la première couche de fibres.
