Embossing method for producing a structured voluminous nonwoven
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 (10a, b) 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 (11) arranged in rows and the surface of the negative roller has lamellas (13) which are arranged in an axial direction and provided with intermediate recesses (14) so that when the rollers roll against each other the lamellas engage in the channels left open by the nops.
