Abstract

Yarns comprising fibers comprising a fluorinated polyester blend are 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 yarns and fibers, and the textile and carpet goods produced therefrom, exhibit durable soil, oil, and water repellency.
