Beschreibung
Zusammenfassung:	The present invention relates to a method for manufacturing an absorbent composite in a sanitary product and to an absorbent composite in a sanitary product, manufactured by means of the method. In the method, at least one liquid absorbing layer (14) is formed by means of the dry forming technique, which absorbing layer comprises natural fibres, such as wood fibres, or natural fibres and plastic fibres mixed with one another, and superabsorbent material (15), and which is bound by means of heat. According to the invention, at least one material layer (13) is dry formed on the absorbing layer (14), before the absorbing layer is bound by means of heat, from fibres crimping in connection with the binding taking place by means of heat.
