<p>A method for producing a nonwoven fibrous, flexible panel having a textured outer surface, including the steps: of providing a needled web comprised of interengaged first fibers and second thermoplastic fibers; needlepunching the web to produce the textured outer surface; and passing a fluid, at a temperature sufficient to melt at least a portion of the second thermoplastic fibers, through the web in a direction from the textured outer surface to produce a plurality of weld joints of the melted second thermoplastic fibers, the textured outer surface thereafter being substantially free of the second thermoplastic fibers. A nonwoven fibrous panel produced by the methods characterized herein is also described.</p> |
