Abstract of the Disclosure As a spin-finish lubricant for processing synthetic fibers, a nonionic polyalkoxylate surfactant of the fatty-ether alkoxylate, fatty-ester alkoxylate, or block or heteric ethylene oxide/propylene oxide type is made which contains a substantial proportion of alkali-metal or alkaline-earth metal ions and preferably anions of volatile nature, such as the anions of saturated carboxylic acids containing up to 18 carbon atoms. Such lubricants display improved stability when during a spin-finishing operation the synthetic fiber to which they have been applied is passed over a heater plate maintained at 150 to 300 degrees Centigrade. -1-
