Abstract

An absorbent article, such as a diaper, pant diaper, incontinence guard, sanitary napkin, wound dressing and the like, comprising a layer of continuous fibers, so-called tow, which have been bonded together in points, lines or spots in a bonding pattern (10), but otherwise are substantially unbonded to each other, and which layer comprises at least two zones (5a-e), as seen in the cross-sectional direction of the layer, which zones are different with respect to one or several properties such as basis weight, density, pore size, hydrophilicity/hydrophobicity and/or other absorption properties and/or properties affecting skin condition. Said layer can either be used as a liquid acquisition layer (5) in the article underneath a topsheet (2), as a topsheet (12), or as a combined topsheet and liquid acquisition layer (22).
