Abstract: A needle punching process is provided for producing a needle felted fabric that is useful for producing artificial leather. In the needled fabric some of the fibers are displaced by needles and caused to penetrate through others of the fibers; at least 60 percent of the fibers which penetrate do so either individually or as a group of two or three fibers.
