Fluorochemical finishes are the most widely used repellent agents for textile processing and both natural and synthetic fibers can be treated [5,6]. Fluorocarbons are unique, for they can repel water as well as oils because of their very low surface energy (γC~15 dynes/cm or less) [7]. Excellent chemical and thermal stability of fluorocarbons allows them to have good durability during laundering, dry-cleaning, and tumble-drying. In addition, fluorocarbon finishes can be applied at a lower add-on (
