Abstract
(EN)
A nonwoven fabric for absorbent articles, which comprises a first fiber layer and a second fiber layer that is positioned on one main surface of the first fiber layer, and which is configured such that: the first fiber layer contains first sheath-core type composite fibers; the second fiber layer contains second sheath-core type composite fibers and cotton; the fineness (F1) of the first sheath-core type composite fibers is lower than the fineness (F2) of the second sheath-core type composite fibers; the value of (F2 - F1) is from 0.1 dtex to 1.5 dtex (inclusive); and the requirements described below are satisfied. (i) The sheath component of the first sheath-core type composite fibers and the sheath component of the second sheath-core type composite fibers contain a polyethylene; the heat of fusion ∆H of the sheath component of the first sheath-core type composite fibers is 130 J/g or more; and the heat of fusion ∆H of the sheath component of the second sheath-core type composite fibers is 130 J/g or more.

Tissu non tissé pour articles absorbants, qui comprend une première couche de fibres et une seconde couche de fibres qui est positionnée sur une surface principale de la première couche de fibres, lequel tissu est conçu de telle sorte que : la première couche de fibres contient des premières fibres composites de type noyau-enveloppe ; la seconde couche de fibres contient des secondes fibres composites de type noyau-enveloppe et du coton ; la finesse (F1) des premières fibres composites de type noyau-enveloppe est inférieure à la finesse (F2) des secondes fibres composites de type noyau-enveloppe ; la valeur (F2 - F1) varie de 0,1 dtex à 1,5 dtex (bornes incluses) ; et les exigences décrites ci-dessous sont satisfaites. (i) Le composant formant l'enveloppe des premières fibres composites de type noyau-enveloppe et le composant formant l'enveloppe des secondes fibres composites de type noyau-enveloppe contiennent un polyéthylène ; la chaleur de fusion ∆H du composant formant l'enveloppe des premières fibres composites de type noyau-enveloppe est égale ou supérieure à 130 J/g ; et la chaleur de fusion ∆H du composant formant l'enveloppe des secondes fibres composites de type noyau-enveloppe est égale ou supérieure à 130 J/g.
