Abstract
A topsheet having openings and associated liquid guide capillary tubes is provided. The topsheet has a fabric-like appearance and oblique openings are formed at the lower ends of the respective liquid guide capillary tubes. Top openings of this topsheet, for use in a sanitary absorptive article, present plane configurations respectively defined by combination of straight and curved lines and each pair of adjacent top openings are separated from each other by a fine rib.
Bottom openings have peripheral edges which are irregularly undulating. A mold for the topsheet is provided with a plurality of openings each presenting an asymmetric figure or a linearly symmetric figure having a single axis of symmetry.
