Patent ID: 8889256

Claim:
A fabric comprising a plurality of filaments, at least a portion of the filaments comprising a blend composition comprising a first aromatic polyester selected from the group consisting of: poly(trimethylene terephthalate) (PTT), poly(ethylene naphthalate) (PEN), poly(ethylene isophthalate), poly(trimethylene isophthalate), poly(butylene isophthalate), mixtures thereof, and copolymers thereof, and a second aromatic polyester in contact therewith, wherein the second aromatic polyester is present in the blend composition at a concentration in the range of 0.1 to 10% by weight of the total composition; and, wherein the second aromatic polyester comprises a molar concentration in the range of 40 to 100 mol-% of fluorovinylether functionalized repeat units represented by structure I wherein, Ar represents a benzene or naphthalene radical; each R is independently H, C 1 -C 10 alkyl, C 5 -C 15 aryl, C 6 -C 20 arylalkyl; OH, or a radical represented by the structure (II) with the proviso that only one R can be OH or the radical represented by the structure II; R 1 is a C 2 - C 4 alkylene radical which can be branched or unbranched; X is O or CF 2 ; Z is H or Cl; a=0 or 1; and, Q represents the structure (Ia) wherein q=0-10; Y is O or CF 2 ; R f 1 is (CF 2 ) n , wherein n is 0-10; and, R f 2 is (CF 2 ) p , wherein p is 0-10, with the proviso that when p is 0, Y is CF 2 .
