ABSTRACT:
Non-woven fabrics suitable for use as carpeting and the like are produced by needlepunching staple length monofilament fibers having an elastic modulus of from 5,000 to 60,000 psi. The fibers are also characterized by an area moment of inertia of from 400.times.10.sup.14 to 7,000.times.10.sup.14 in.sup.4 and a stiffness parameter of from 1.times.10.sup.-5 to 1.times.10.sup.-8 lb-in.sup.2.
