Abstract
The present invention is directed to a method of forming a nonwoven fabric, which exhibits a first three-dimensional image and a second three-dimensional image whereby the first and second three-dimensional images are dissimilar from one another. In particular, the present invention contemplates a fabric comprised of sequentially formed three-dimensional images that are formed from a pre-entangled precursor web entangled on a first three-dimensional transfer device so as to impart a first image therein, then subjected to hydroentanglement on a second three-dimensional image transfer device wherein a second three-dimensional image is imparted to the web that is different from the first three-dimensional image, the resulting nonwoven fabric presenting aesthetic and tactile qualities representative of both imparted images.
