Patent

CA 2141649

The invention relates to a method for manufacturing an absorbent fibre layer (15), and an absorbent fibre layer. In the method, at least one material layer (16) consisting of a mixture of natural fibres, such as wood fibres, and plastic fibres is formed by a dry-forming technique, and at least one other material layer (17) consisting of natural fibres, or a mixture of natural fibres and plastic fibres, and superabsorbent material (18) is formed on said material layer. The fibre layer (15) is bonded with heat. The invention is characterized in that the superabsorbent material (18) is added to the second material layer (17) to be formed in connection with its dry-forming stage, after which the upper surface of the fibre layer is compacted and its lower surface is moistened and compressed by hot calendering in order to compress the material layer (16) comprising no superabsorbent material into a liquid-spreading layer.
