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.

Abstract: In dye applicators that operate by the pouring principle, it is known to hold back liquid flowing over an overflow weir in a liquid supply chamber located upstream of the weir. To achieve a dye applicator that can be adjusted to a desired working width, this liquid supply chamber is subdivided several times by limiting walls, and a liquid inflow bore is associated with each of the partial liquid supply chambers thus formed. The flanks of the liquid supply chambers delimited by a parallel dam and opposite dam are designed to diverge and to create a plurality of separate liquid supply chambers that expands toward the overflow weir.
