Abstract
A fabric structure used to make textured nonwoven products, the structure being permeable to air and water, comprising a web contact surface having a pattern including a series of raised land areas and corresponding depressions adapted to impart a texture to the nonwoven product produced thereon, and a series of through voids adapted to allow passage of both water and/or air from the fabric surface into and/or through the structure.
