Claims
- 1. A process for improving the oil- and/or water-repellent properties of textiles which comprises treating the textile with from 10 to 100 weight percent pick-up of a treating composition and curing the treated textile at from about 80.degree.C to about 170.degree.C for a period of time of from about 0.1 to about 60 minutes, wherein the treating composition comprises an inert, anhydrous solvent containing from about 0.1 to about 10 weight percent of a polymeric fluorocarbon finishing agent, and from about 0.3 to about 10 weight percent of one or more polyalkylene copolymer extenders of the formulae ##EQU14## wherein C.sub.1 and C.sub.2 are, independently, carbon atoms of the polyalkylene chain represented by --CH.sub.2 -- CH.sub.2).sub.n ; R and R' are, independently, hydrogen, an alkyl group of up to about 20 carbon atoms, phenyl, --COOH, or a segment of the polyalkylene chain; R.sub.1 and R.sub.2 are, independently, alkyl, aryl, aralkyl or alkaryl groups of up to about 20 carbon atoms, and X is a halogen, said polymeric extender having a molecular weight of from about 800 to about 8000.
- 2. The process of claim 1 wherein the wet pick-up is from about 40 to about 80 weight percent.
- 3. A textile with improved water- and/or oil-repellency as produced by the process of claim 1.
