Abstract

See full text

An absorbent article, such as a diaper, a sanitary towel or bandage, having an absorbent core, a liquid-permeable topsheet intended to be in contact with the wearer when the article is worn, and a liquid-impermeable layer arranged on the opposite side of the absorbent core. The liquid-permeable topsheet comprises a perforated but otherwise liquid-impermeable layer, the perforations comprising straight ducts which are of uniform width along the whole of their lengths. The ends of these ducts freely project away from the topsheet and extend into the absorbent core. Fibers extend into the ducts in a manner such that the fiber density in the ducts decreases in a direction away from the free ends of the ducts, so that the fibers form capillaries which taper toward the interior of the absorbent article.
