摘要： Resilient yarn produced from fibers of propylene polymer material. More particularly, the invention relates to yarn and pile fabric such as carpeting made therefrom, in which the fiber is a propylene terpolymer or copolymer and mixtures thereof. Specifically, it relates to yarn produced from propylene polymer compositions based on terpolymers of propylene with ethylene and C₄-C₈ alpha-olefin; compositions of copolymers of propylene with C₄-C₈ alpha-olefin together with copolymers of propylene and ethylene or terpolymers of propylene-ethylene-C₄-C₈ alpha-olefin; compositions of terpolymers of propylene, ethylene and C₄-C₈ alpha-olefin in combination with copolymers of propylene and C₄-C₈ alpha-olefin as well as copolymers of ethylene and C₄-C₈ alpha-olefin; random crystalline propylene copolymers with ethylene or a C₄-C₈ alpha-olefin as well as such compositions containing elastomeric propylene copolymers. In particular, the invention relates to yarn produced from blends of such copolymers and terpolymers and compositions with crystalline polypropylene homopolymer.
