Abstract
Absorbent article such as a diaper, pant diaper, incontinence guard, sanitary napkin, wound dressing or the like comprising a layer of continuous fibers (9), so called tow, which is bonded in points, spots or lines in a bonding pattern (10), but where the fibers otherwise are substantially unbonded to each other. The layer can either be used as a liquid acquisition layer (5) in the article under the topsheet (2), as a topsheet (12) or as a combined topsheet and liquid acquisition layer (22).
Claims20
An absorbent article, the absorbent article comprising:
- a liquid permeable topsheet,
- a liquid impervious backsheet,
- an absorbent body arranged therebetween, and
- a layer of continuous filament fibers, which are bonded together in a bonding pattern, at least some of said fibers being thermoplastic and the bonding pattern being achieved by thermal bonding, with the bonds creating open spaces beneath the topsheet to allow for liquid distribution, wherein the bonding pattern comprises points, spots or lines which cross a longitudinal direction of the continuous filament fibers, and wherein different bonding lines overlap each other as seen in a transverse direction of the article, so that a main part of the filament fibers are bonded along at least a part of their length.
An absorbent article comprising:
- a layer of continuous filament fibers, which are bonded together in a bonding pattern, at least some of said fibers being thermoplastic and the bonding pattern being achieved by thermal bonding, with the bonds creating channels along the surface of the layer to allow for liquid distribution, wherein the bonding pattern comprises points, spots or lines which cross a longitudinal direction of the continuous filament fibers, and wherein different bonding lines overlap each other as seen in a transverse direction of the article, so that a main part of the filament fibers are bonded along at least a part of their length:
- a liquid impervious backsheet, and
- an absorbent body arranged therebetween.
