Abstract
A topsheet for use in body fluid absorptive articles is so improved that collapse and clogging of liquid passages therein may be reliably avoided. The topsheet includes an upper sheet, provided with skin-contacting areas and liquid passages, and a lower sheet provided with skin-non-contacting areas, areas welded to the liquid passages, and exposed areas. The exposed areas are welded to each of the liquid passages around lower openings thereof so as to protect the liquid passage against collapse and clogging. The exposed areas define a skin-contacting surface which rises up into each of the liquid passages without extending above the upper surface of the skin-contacting areas. The upper sheet cooperates with the lower sheet to define cavities extending in the direction of the topsheet thickness.
