-1- ABSTRACT This invention relates to a composition comprising a fluorochemical compound useful for treating leather, textiles, end cellulosic materials. The invention also relates to a method for treating these materials with the composition. Although there are many commercially available fluorochemicals which will impart water and oil repellancy to leather and textiles, they are generally applied from solutions wherein the solvent is a chlorinated hydrocarbon, e.g., trichloroethane. These solvents are often deleterious to leather and dyes that have been applied to leather. Many consumers find chlorinated hydrocarbons objectionable for both health and environmental reasons. This invention provides compositions containing a fluorochemical compound which confer durable water and oil repellancy to leather and textiles while not adversely affecting the appearance, feel, hand and other desirable qualities of the leather and textiles. The fluorochemical compounds useful in the practice of this invention are capable of providing up to about 30 times as much water repellancy to leather as the best commercially available leather treatment products. Fluorochemical compounds useful in this invention contain (a) a fluoroaliphatic moiety, (b) an aliphatic moiety, and (c) an organic group which connects moiety (a) and moiety (b). The preferred fluorochemical compounds contain one or more sites of unsaturation, which allows crosslinking after they are applied to the surface of the leather or textiles. The fluorochemical compounds of this invention can be applied from solvents that are not harmful to the health of the consumer, to leather itself, to dyes previously applied to leather, or to textiles and cellulosic materials.
