The invention relates to a three-dimensionally embossed non-woven fabric, which is comprised of fibers and/or filaments (3) oriented primarily in the moving direction (2) of the machine, and has zones (5, 7) with regularly alternating elevations (4a, 8a) and indentations (4b, 8b), which are separated from one another by non-embossed areas (6) that are continuous in the moving direction (2) of the machine. These non-embossed areas constitute a proportion ranging from 5 % to 50 % with regard to the entire surface of the non-woven fabric (1) and the elevations (4a, 8a) and indentations (4b, 8b), when viewed from the opposite side, form indentations or elevations respectively, whereby the surfaces (10a, 10b) delimited by the elevations give the non-woven fabric an apparent thickness ranging from 0.5 mm to 5.5 mm.
La présente invention concerne une étoffe nappée gaufrée tridimensionnelle qui est composée principalement de fibres et/ou filaments (3) dont l'orientation correspond à la direction (2) de la machine, et présente des zones (5, 7) comprenant des parties en saillie (4a, 8a) et des parties creuses (4b, 8b) alternées de façon régulière qui sont séparées par des zones (6) non gaufrées, continues dans la direction (2) de la machine, la proportion de celles-ci valant de 5 à 50 % vis-à-vis de la surface totale de l'étoffe nappée (1). Selon l'invention, les parties en saillie (4a, 8a) et les parties creuses (4b, 8b) forment de l'autre côté respectivement des parties creuses et des parties en saillie, et les surfaces (10a, 10b) limitées par les parties en saillie confèrent à l'étoffe nappée (1) une épaisseur apparente de 0,5 mm à 5,5 mm.
