<p>The present invention is directed to a method of forming a two-sided nonwoven fabric, which exhibits a pronounced three-dimensional image that is durable to both converting and end-use application. In particular, the present invention contemplates that a fabric is formed from a first precursor web (P) comprising a first fibrous matrix and a second precursor web (P) comprising a second fibrous matrix. Between the first and second precursor web, a fluid-pervious support layer or scrim is interposed and subjected to hydroentanglement on a moveable imaging surface having a three-dimensional image transfer device (24). By formation of a nonwoven fabric in this fashion, a three-dimensional image that is durable to abrasion and distortion due to elongation is imparted and a product formed which exhibits on its opposite surfaces the unique properties of the respective fibrous matrix used.</p> |
