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.
Claims9
A method of making a colored non-woven composite material, comprising the steps of:
- providing a first non-woven layer having a heterogeneous fiber density described in a predetermined pattern or image and a first color,
- providing a second non-woven layer having a different aesthetic quality than the first non-woven layer and having a heterogeneous fiber density described in a predetermined pattern or image,
- positioning said first and second non-woven layers in surface to surface juxtaposition, applying high pressure fluid streams upon the second non-woven layer to induce relocation of the fibrous component of the second non-woven layer into the fibrous structure of the first non-woven layer,
- whereby the fibrous component of the second non-woven layer is apparent on the face of the first non-woven layer in the regions of the first non-woven layer where the fiber density is lower than the surround areas of the first non-woven layer.
