Abstract

Disclosed herein are fluorochemical blends suitable for producing repellency to low surface tension fluids such as, for example, alcohols, aldehydes, ketones and hydrophilic liquids, such as those containing surfactants. The fluorochemical blends may be beneficially utilized to produce low surface tension fluid repellency in extruded articles such as fibers and fibrous web materials, films and foams. Such repellent extruded articles are highly useful in a wide range of limited use and disposable products such as, for example, personal care products, mortuary and veterinary products, protective wear garments, and medical care garments and products. The fluorochemical blends include at least a first fluorochemical having a majority of first fluoroaliphatic groups having 4 or fewer carbon atoms, and a second fluorochemical having a majority of second fluoroaliphatic groups having 6 or more carbon atoms.
