Abstract: Saxony carpet containing a pile yarn comprising propylene polymer yarn of increased resiliency and shrinkage, compared to crystalline propylene homopolymer yarn, having a continuous strand of multiple monofilament fibers, said fibers consisting essentially of certain propylene polymer blends and materials.

Abstract: Fabric prepared from a propylene polymer yarn of increased resiliency and shrinkage, compared to crystalline propylene homopolymer yarn, comprising a strand of multiple monofilament fibers, the fibers consisting essentially of certain propylene polymer blends and materials.

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.

Abstract: Polyolefin yarn capable of increased shrinkage comprising continuous strand of multiple monofilament fibers or staple fibers of propylene polymer material consisting essentially of at least about 5 parts by weight, but less than 50 parts by weight of syndiotactic propylene polymer having a syndiotactic pentad fraction of 0.7 or more, blended with crystalline isotactic propylene polymer, each propylene polymer material independently selected from the group consisting of:(I) homopolymers of propylene; and(II) random crystalline propylene copolymers, terpolymers or both, consisting essentially of from about 80 to about 98.5% of propylene; and from about 1.5 to about 20.0% of at least one comonomer selected from the group consisting of ethylene and C.sub.4 -C.sub.8 alpha-olefins; said copolymer preferably containing from about 2 to about 10% ethylene when said C.sub.4 -C.sub.8 alpha-olefin is not present; and said terpolymer preferably containing from about 0.5 to about 5% ethylene when said C.sub.4 -C.sub.
