摘要

A topsheet (2) for body exudates absorbent article (1) includes a hydrophilic nonwoven fibrous sheet (6) and a plurality of thermoplastic synthetic resin filaments (7) extending in one direction parallel to one another and continuously bonded to an upper surface (9) of the nonwoven fibrous sheet (6) so that a composite sheet of these sheets and filaments have crests (11) and troughs (12) alternately repeating longitudinally of the filaments and respectively extend transversely of the filaments. An apparatus and a method for manufacturing the topsheet (2) are also disclosed, wherein a pair of mutually engageable embossing rolls (120) are used for forming the crests (11) and the troughs (12) onto the composite sheet.
