Patent ID: 8663799

Claim:
A fiber comprising a condrapable polyolefin composition comprising: i. 40 to 99.99 wt % of blend of a polypropylene homopolymer and a copolymer, wherein the copolymer has: (a) 75-95 wt % of propylene-derived units; (b) 5-25 wt % of ethylene-derived units; (c) a melting temperature (Tm) of 25° C. to 110° C.; (d) a heat of fusion between 1.0 to 50.0 J/g; and (e) an mm triad tacticity of 75% or greater; wherein the wt % is based upon the weight of the homopolymer, copolymer, and the NFP, and ii. functionalized slip agent; and iii. a non-functionalized plasticizer (NFP), wherein the NFP is selected from polyalphaolefins comprising oligomers or polymers of C 5 to C 14 olefins, gas-to-liquid hydrocarbon, Group III mineral oils, or a combination thereof, having (1) a VI of 120 or more, (2) a flash point greater than 200° C., (3) a pour point of −20° C. or less, (4) a specific gravity of less than 0.86, and wherein ethylene homopolymers and copolymers having a weight average molecular weight of from 500 to 10,000 are substantially absent from the composition.
