Abstract
The invention relates to a method for producing a structured voluminous non-woven fabric, comprising the following steps: producing a spunbonded non-woven fabric consisting of a plurality of monofilaments which are stretched only at 50 to 70% of the maximum possible stretch range to form a fiber skein and subsequent processing the raw non-woven fabric by means of a second pair of rollers ( ) with a metal outer jacket to improve the velvet finish. In the second pair of rollers, the positive elements of the positive roller are nops ( ) arranged in rows and the surface of the negative roller has lamellas ( ) which are arranged in an axial direction and provided with intermediate recesses ( ) so that when the rollers roll against each other the lamellas engage in the channels left open by the nops.
