发明名称 ABSORBENT STRUCTURE, AND PRODUCTION OF ABSORBENT STRUCTURE BY MAT FORMATION TOGETHER WITH ADHESIVE-BONDED LAYER
摘要 Absorbent structure (1) consisting of an absorbent material layer (2) of adhesive-free cellulose fibres (4) and an airlaid material layer (3) of adhesive-bonded cellulose fibres (5), and a method for producing an absorbent structure (1) which is intended for use in an absorbent article. The layers are bonded together by means of the adhesive of the airlaid material (3) functioning as a binding material and fibres (4) from the absorbent material layer (2) extending into the airlaid material (3). In the method, the absorbent material (2) is mat-formed on an airlaid material (3). Alternatively, the absorbent material (2) is mat-formed and an airlaid material (13) is then laid on top of it. After the material layers have been laid together, they are compressed (24) at a temperature in excess of 100 DEG C. During the compression (24), the adhesive of the airlaid material is softened, and the two layers are bonded together. Some of the fibres (4) from the absorption material (2) also penetrate down into the airlaid material (3) and further connection between the layers is achieved.
