Resilient, high strinkage propylene polymer yarn and articles made therefrom

摘要

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 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 and copolymers of ethylene and C4-C8 alpha-olefin; random crystalline propylene copolymers with ethylene or a C4-C8 alpha-olefin; and a heterophasic polyolefin composition; and fabric, especially pile fabric, such as carpeting, produced therefrom.
