To prevent body fluids from flowing backward through a liquid-permeable topsheet 2 for use in body fluids absorptive goods 1, the topsheet 2 is formed by a nonwoven fabric made of thermoplastic synthetic fibers appropriately fused together and the sheet 2 is provided with openings 16 and a skin-contacting region 17 continuously extending around the openings 16. A first zone 11 of the topsheet 2 has a water-resistance at least in the skin-contacting region which is higher than a water-resistance in a second zone 12, 13 extending outside the first zone 11 so as to suppress a back flow of body fluids possibly occurring in the skin-contacting region 17.

Pour empêcher les liquides organiques de refouler à travers une couche supérieure perméable aux liquides (2) pour usage dans des produits d'absorption des liquides organiques (1), la couche supérieure (2) est formée d'un tissus non tissé fabriqué de fibres synthétiques en thermoplastique thermofixées et la couche (2) est pourvue d'ouvertures (16) et d'une région en contact avec la peau (17) qui s'étend autour des ouvertures (16). L'imperméabilité d'une première zone (11) de la couche supérieure (2), au moins dans la région qui est en contact avec la peau, est supérieure à l'imperméabilité d'une deuxième zone (12), (13) qui s'étend au-delà de la première zone (11), de manière à supprimer tout refoulement de liquides organiques pouvant survenir dans la région qui est en contact avec la peau.
