Beschreibung
Zusammenfassung:	A water-dispersible fluid absorber such as a sanitary pad includes a water-dispersible top layer; a water-dispersible absorbent layer; a leakproof layer of a polyvinyl alcohol; and a water-dispersible bottom layer. The leakproof layer is bonded to the top layer and the bottom layer by ultrasonic welding. A method of manufacturing a water-dispersible fluid absorber such as a sanitary pad includes assembling a water-dispersible top layer, a water-dispersible absorbent layer, a leakproof layer of a polyvinyl alcohol and a water-dispersible bottom layer; and bonding the leakproof layer to the top layer and the bottom layer by ultrasonic welding. A further water-dispersible fluid absorber includes a cellulose-based super absorbent material, an alginate-based super absorbent material, a chitosan-based super absorbent material, and/or a polyethylene glycol-based super absorbent material. A further water-dispersible fluid absorber comprises a thick portion formed to create a raised area under the perineum. A further water-dispersible fluid absorber includes a pressure sensitive adhesive arranged in a plurality of portions.
