| 摘要 |
Woven, knit, and non-woven fabrics, and garments and other textile goods fabricated therefrom, are prepared from yarns comprising fibers comprising a fluorinated polyester blend prepared by melt blending a fluorovinyl ether functionalized polyester with a non-fluorinated polyester. The fluoroether functionalized polyester can be a homopolymer or a copolymer. The goods so produced exhibit durable soil, oil, and water repellency. |

1. 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, C1-C10 alkyl, C5-C15 aryl, C6-C20 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; R1 is a C2 - C4 alkylene radical which can be branched or unbranched; X is O or CF2; Z is H or Cl; a=0 or 1; and, Q represents the structure (Ia) wherein q=0-10;
Y is O or CF2;Rf1 is (CF2)n, wherein n is 0-10;and,Rf2 is (CF2)p, wherein p is 0-10, with the proviso that when p is 0, Y is CF2. |
