Abstract
(EN)
The present invention provides an absorbent article including a top surface sheet which is not liable to impart unpleasant stimulation to the skin of a wearer, and which has an excellent feel. In an absorbent article according to the present invention, a top surface sheet (2) is provided with a first fiber layer (2a) which includes water-retentive fibers (F1), and which forms a top surface of the top surface sheet (2) on a skin side thereof, and a second fiber layer (2b) which includes thermoplastic resin fibers (F2) and water-retentive fibers (F1), which is adjacent to a non-skin side of the first fiber layer (2a), and which forms a top surface of the top surface sheet (2) on the non-skin side thereof, wherein: the proportion of water-retentive fibers (F1) among the fibers forming the first fiber layer (2a) is greater than the proportion of water-retentive fibers (F1) among the fibers forming the second fiber layer (2b); and at least a portion of the water-retentive fibers (F1) contained in the first fiber layer (2a) are covered by melted material (F2M) of the thermoplastic resin fibers (F2), in at least a portion of an entangled part (PE) in which the fibers are entangled.

La présente invention concerne un article absorbant comprenant une feuille de surface supérieure qui ne risque pas de procurer une stimulation désagréable à la peau de l'utilisateur, et qui présente un toucher agréable. Dans un article absorbant selon la présente invention, une feuille de surface supérieure (2) est pourvue d'une première couche de fibres (2a) qui comprend des fibres à rétention d'eau (F1), et qui forme la surface supérieure du côté faisant face à la peau de la feuille de surface (2), et une seconde couche de fibres (2b) qui comprend des fibres de résine thermoplastique (F2) et des fibres à rétention d'eau (F1), qui est adjacente au côté opposé à la peau de la première couche de fibres (2a), et qui forme une surface supérieure du côté opposé à la peau de la feuille de surface (2), où : la proportion de fibres à rétention d'eau (F1) des fibres formant la première couche de fibres (2a) est supérieure à la proportion de fibres de rétention d'eau (F1) des fibres formant la seconde couche de fibres (2b) ; et au moins une partie des fibres à rétention d'eau (F1) contenue dans la première couche de fibres (2a) sont recouvertes par le matériau fondu (F2M) des fibres de résine thermoplastique (F2), dans au moins une partie d'une partie enchevêtrée (PE) qui contient les fibres enchevêtrées.
