Abstract
Absorbent structure consisting of an absorbent material layer of adhesive-free cellulose fibres and an airlaid material layer of adhesive-bonded cellulose fibres, and a method for producing an absorbent structure which is intended for use in an absorbent article. The layers are bonded together by the adhesive of the airlaid material functioning as a binding material and fibres form the absorbent material layer extending into the airlaid material. In the method, the absorbent material is mat-formed on an airlaid material. Alternatively, the absorbent material is mat-formed an airlaid material is then laid on top of it. After the material layers have been laid together, they are compressed at a temperature in excess of 100° C. During the compression, the adhesive of the airlaid material is softened, and the two layers are bonded together. Some of the fibres from the absorption material also penetrate down into the airlaid material and further connection between the layers is achieved.
