A topsheet for body fluid absorptive articles wherein liquid passages formed in the topsheet may be stabilized during use of the articles and the topsheet may offer cloth-like feeling and appearance. The topsheet for the body fluid absorptive articles is composed of an upper sheet layer made from melt blow nonwoven fabric formed with the liquid passages and a lower fibrous layer underlying the upper sheet layer and bonded thereto adjacent the respective liquid passages as well as adjacent lower openings thereof. The melt blow nonwoven fabric provides the topsheet with the cloth-like feeling and appearance while the lower fibrous layer stabilizes the liquid passages so that the liquid passages should not be collapsed and the lower openings of these passages should not be distorted.

Feuille de contact pour articles destinés à l'absorption des fluides corporels dont les perforations permettant le passage des liquides peuvent être stabilisées durant l'utilisation de l'article en question de telle sorte que la feuille de contact conserve les caractéristiques de confort et d'apparence associées à une étoffe. La feuille de contact en question se compose d'une couche supérieure en textile non-tissé en microfibres comportant les passages pour liquides et d'une couche fibreuse sous-jacente liée à la couche supérieure au voisinage des passages pour liquides et de leurs ouvertures inférieures. Le textile non-tissé en microfibres préserve les caractéristiques de confort et d'apparence de la feuille de contact en empêchant la déformation des passages pour liquides.
