Abstract
A method of providing a color enhanced, patterned nonwoven based composite fabric wherein a hydroentangled, imaged nonwoven facing fabric exhibits variable fiber density in selected regions and where a colored backing material is laminated to the facing layer such that the color of the backing layer is observed as variable hues which coincide with regions of lower fiber density in the facing layer.
