Abstract
A composite fabric is provided that contains staple fibers hydraulically entangled with a nonwoven web formed from continuous filaments. A portion of the staple fibers is entangled with the web, while another portion protrudes through the web. The resulting surface topography has one surface with a preponderance of the smooth, staple fibers, and another surface with a preponderance of the continuous filaments from the nonwoven web, but also including some of the protruded smooth, staple fibers. Thus, each surface contains smooth staple fibers and is soft.
