ABSTRACT:
A method of forming abrasion resistant nonwoven fabrics by hydroentanglement includes providing a precursor web. The precursor web is subjected to hydroentanglement on a three-dimensional image transfer device to create a patterned and imaged fabric. Treatment with an initial pre-dye finish enhances the integrity of the fabric, permitting the nonwoven to exhibit desired physical characteristics, including strength, durability, softness, and drapeability. The pre-dye finish treated nonwoven may then be dyed by means applicable to conventional wovens. A post-dye finish may then be applied to further enhance the performance of the nonwoven fabric.
