Abstract
A novelty yarn comprising a ground strand of spun staple fibers with relatively short varying length and varying size auxiliary strands of staple fibers randomly distributed along the ground strand and spirally twisted therearound. The largest size auxiliary strands have portions thereof formed of such a large number of fibers so arranged spirally around the ground strand that adjacent turns of those portions overlie and substantially shield the underlying ground strand from view. Other intermediate size auxiliary strands are formed of a lesser number of fibers and are so arranged spirally around the ground strand that both the ground strand and the auxiliary strand are exposed to view. Still other smallest size auxiliary strands are formed of such a few number of fibers arranged spirally around the ground strand so as to be barely discernible thereon. The ground strand and the auxiliary strand may be of the same or of differing color characteristics.
