The invention relates to a method for producing a structured voluminous non- woven fabric, comprising the following steps: production of 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 of 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 said pair of rollers, the positive bodies of the positive roller are nops (11) arranged in rows and the surface of the negative roller has lamella connectors (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.

L'invention concerne un procédé pour la fabrication d'un non-tissé structuré ayant du volume. Ce procédé consiste à fabriquer un non-tissé par filature directe à partir d'une pluralité de monofilaments qui sont étirés uniquement dans la plage de 50 à 70 % de l'étirage maximal possible et sont déposés pour former un écheveau de fibres, et à traiter ultérieurement le non-tissé brut en vue d'accroître son caractère velouté, à l'aide d'une deuxième paire de cylindres (10a, b) dans laquelle les revêtements extérieurs des cylindres sont constitués de métal, les éléments positifs du cylindre positif sont des boutons (11) disposés en rangées et la surface du cylindre négatif présente des parties jointives lamellaires (13) disposées en sens axial et pourvues d'évidements intermédiaires (14), de sorte que lors de la rotation des cylindres l'un contre l'autre, les lamelles s'engagent dans les passages laissés libres par les boutons.
