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