Abstract
Colored patterning of a web-shaped nonwoven or a composite made of a nonwoven and a fabric or knit is achieved by water jet needling. The nonwoven provided as the upper layer of two layers is provided with one or more colors or is colored or printed itself and is placed on a second nonwoven or a woven or one that has a different color. Then both layers are subjected to the water jets that displace the fibers, with the colored fibers in the first layer being displaced into the second layer to produce a pattern on the underside of the second layer. It is also possible, instead of colored fibers in the nonwoven of the upper layer, to move them when they are not colored into a second layer that can have any color.
