Abstract:
A three-dimensionally embossed non-woven fabric, which is comprised of fibers and/or filaments () oriented primarily in the moving direction () of the machine, and has zones () with regularly alternating elevations (, ) and indentations (, ), which are separated from one another by non-embossed areas () that are continuous in the moving direction () 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 () and the elevations (, ), and indentations (, ), when viewed from the opposite side, form indentations or elevations respectively, whereby the surfaces (, ) delimited by the elevations give the non-woven fabric an apparent thickness ranging from 0. 5 mm to 5. 5 mm.
