  • Polymer compositions for staple and multifilament fibers
    Patent number: 9879364
    Abstract: The invention relates to a fiber comprising a polymer blend of (a) from about 90 to about 99 wt % of a propylene polymer and (b) from about 1 to about 10 wt % of a polymer blend modifier, comprising a first propylene-based polymer wherein the first propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin and a second propylene-based polymer wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin, wherein the second propylene-based polymer is different than the first propylene-based polymer and wherein the polymer blend modifier has a MFR of greater than about 1,000 g/10 min to less than about 10,000 g/10 min; and wherein the propylene polymer has a MFR of less than about 15 g/10 min.
