Abstract
The present invention relates generally to a method of making nonwoven fabrics, wherein the fabrics are formed from splittable filaments or staple length fibers having a plurality of sub-components which are at least partially separable. The filaments or fibers are at least partially separated into their sub-components attendant to hydroentanglement, which can be effected on a three-dimensional image transfer device. Improved physical properties, including improved tensile strength, elongation, and Taber Abrasion resistance are achieved.
