ABSTRACT:
Disclosed is a polyolefin yarn capable of increased resiliency and shrinkage comprising continuous strands of multiple monofilament fibers or staple fibers of propylene polymer material, optionally blended with polypropylene homopolymer, said propylene polymer material selected from the group consisting of terpolymers of propylene with ethylene and C.sub.4 -C.sub.8 alpha-olefin; compositions of copolymers of propylene with C.sub.4 -C.sub.8 alpha-olefin together with copolymers of propylene and ethylene or terpolymers of propylene-ethylene-C.sub.4 -C.sub.8 alpha-olefin; compositions of terpolymers of propylene, ethylene and C.sub.4 -C.sub.8 alpha-olefin in combination with copolymers of propylene and C.sub.4 -C.sub.8 alpha-olefin and copolymers of ethylene and C.sub.4 -C.sub.8 alpha-olefin; random crystalline propylene copolymers with ethylene or a C.sub.4 -C.sub.8 alpha-olefin; and a heterophasic polyolefin composition; and fabric, especially pile fabric, such as carpeting, produced therefrom.
