of the yarn and stopped the finish circulating pump bulked yarn made in accordance with this example prior to stoppage of the pump had a poor mechanical quality rating fabric made from polyamide yarn prepared in accordance with this example prior to pump stoppage had excellent oil repellency about 50 parts of fluorochemical composition 1 were added to 50 parts of an alkanol amide resulting from the reaction of coco fatty acid containing about 6 to 18 carbon atoms and diethanolamine and the mixture was heated to 80 u00b0 c at which temperature the fluorochemical composition 1 melted and formed a clear homogeneous mixture this oil was then added to 800 parts of water heated to about 80 u00b0 c and the mixture was agitated to form an emulsion which was then cooled to about 60 u00b0 c the oil particles in this emulsion had a particle size of less than one micron and the emulsion was stable for more than thirty days without signs of separation this emulsion was then blended with 100 parts of an oil composition consisting of about 44 5 percent by weight of butyl stearate about 27 75 percent by weight of sorbitan monooleate and about 27 75 percent by weight of polyoxyethylene tallow amine containing about 20 moles of ethylene oxide per mole of tallow amine reference u s.
