Abstract:
The present invention provides a method of making a nonwoven fabric of continuous fibers that includes forming a nonwoven web on a highly porous woven or knitted forming fabric that defines a pattern of recesses that are bordered by spaced apart filaments extending between the outer surfaces of the fabric and that allows air to pass both downwardly and sidewardly through the forming fabric. Bonded nonwoven webs are formed having protrusions with very low density and high surface area.
