Claims
- 1. A saxony carpet containing a primary backing and twisted, evenly sheared, heat-set pile yarn, said yarn being in the form of individual lengths of plied yarn or tufts, each of which is attached to and projects upwardly from said backing and terminates as a cut end, said 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 a member selected from the group consisting of, by weight,
- I. a blend of crystalline propylene homopolymer at a concentration of about 10-70% of the blend, and (a) a random crystalline terpolymer consisting essentially of about 96.0-85.0% of propylene, about 1.5-15.0% of ethylene, and about 2.5-10% of a C.sub.4 -C.sub.8 alpha-olefin or (b) a random, crystalline, propylene polymer consisting essentially of propylene and about 1.5-20.0% of an olefin selected from the group consisting of ethylene and C4-C8 aplha-olefins; and
- II. a proplylene polymer material, optionally in a blend with crystalline, propylene homopolymer, said homopolymer being at a concentration up to about 70% of the blend, said propylene polymer material being selected from the group consisting of:
- (a) a composition of random, crystalline, propylene polymers consisting essentially of:
- (1) about 30-65% of a copolymer of about 80-90% propylene, and a C.sub.4 -C.sub.8 alpha-olefin, and
- (2) about 35-70% of a copolymer of propylene and ethylene and optionally about 2-10% of a C.sub.4 -C.sub.8 alpha-olefin, said copolymer containing about 2-10% ethylene when said C.sub.4 -C.sub.8 alpha-olefin is not present, and about 0.5-5% ethylene when said C.sub.4 -C.sub.8 alpha-olefin is present;
- (b) a composition of random, crystalline, propylene polymers and a predominantly ethylene copolymer, which composition consists essentially of:
- (1) about 15-35% of a terpolymer of about 90-93% propylene, about 2-3.5% ethylene, and about 5-6% C.sub.4-C.sub.8 alpha-olefin,
- (2) about 30-75% of a copolymer of about 80-90% propylene, and a C.sub.4 -C.sub.8 alpha-olefin, and
- (3) about 20-60% of a copolymer of about 91-95% ethylene, and a C.sub.4 -C.sub.8 alpha-olefin;
- (c) a heterophasic, polyolefin composition consisting essentially of:
- (1) 90-55% of polymeric material selected from the group consisting of a propylene homopolymer having an isotactic index greater than 90, and a crystalline copolymer of propylene and an alpha-olefin of the formula CH.sub.2 .dbd.CHR, where R is H or C.sub.2 -C.sub.6 alkyl said olefinic material being less than 10% of the copolymer, and
- (2) 10-45% of an elastomeric polymer and propylene and olefinic material selected from the group consisting of alpha-olefins of the formula CH.sub.2 .dbd.CHR, where R is H or C.sub.2 -.sub.6 alkyl, said olefinic material being 50-70% of said elastomeric copolymer, and 10-40% of said elastomeric copolymer being insoluble in xylene at ambient temperature.
- 2. The carpet of claim 1 the yarn is comprised of bulk continuous fibers or staple fibers.
