A method for manufacturing an absorbent composite in a sanitary product wherein at least one liquid absorbing layer (14) is formed by the dry forming technique. The absorbing layer includes natural fibers, such as wood fibres, or natural fibers and plastic fibers mixed with one another, and superabsorbent material (15), and is bound by heat. At least one material layer (13) is dry formed on the absorbing layer (14), before the absorbing layer is bound by heat, from fibers crimping in connection with the binding taking place by heat.
