ABSTRACT:
A method of making sanitary products giving a high wearing comfort includes the step of forming three superposed interconnected layers (14, 15, 16). The outer layers (14, 16) are made of hydrophobic fibers and the intermediate layer (15) is made of hydrophilic fibers. The top sheet of the sanitary product is constructed of the layer (16), and has flow lines throughout the layer. The flow lines are made by an embossing roller (21) having a pattern of raised ridges. The ridges are provided with a wetting agent which, when applied to the front sheet (16), neutralizes the hydrophobicity of the fibers and provides a pattern of hydrophilic flow lines which allow a body liquid to flow through the top sheet (16).
