| abstract |
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 ( 4 a , 8 a ) and indentations ( 4 b , 8 b ), 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 ( 4 a , 8 a ), and indentations ( 4 b , 8 b ), when viewed from the opposite side, form indentations or elevations respectively, whereby the surfaces ( 10 a , 10 b ) delimited by the elevations give the non-woven fabric an apparent thickness ranging from 0.5 mm to 5.5 mm. |
