Abstract
A method for production of patterned nonwoven fabric from a fibrous web which is subjected to high energy treatment with high velocity water streams not only for fiber entangling but also for patterning of said fibrous web, wherein the fiber entangling treatment is performed on a plurality of non-porous supports arranged in multistaged manner at regular intervals along the path of the fibrous web and the patterning treatment is performed on a separate non-porous support arranged downstream of the previously mentioned non-porous supports and provided on a peripheral surface with a relief pattern.
