Abstract
Lubricants for synthetic fibers such as polyester and nylon are disclosed which are improved oxidation stable polyoxyalkylene lubricant compounds. Such lubricant compounds can be used alone as textile fiber lubricants or in combination with other polyoxyalkylene compounds useful as fiber lubricants but which are subject to oxidative degradation under conditions of heating at temperatures at least above 200.degree. C. An improved textile fiber is produced by the use of such fiber lubricants in conventional processes for producing continuous filament, false twist, textured yarn as well as other type yarns. The improved oxidation stable homopolymer and copolymer, i.e., block or heteric polyoxyalkylene lubricant compounds have the formulas: ##STR1## and can be used alone or in mixtures or in a mixture of an effective proportion thereof of at least 25% by weight based on the total weight of the mixture with one or more of any prior art polyoxyalkylene fiber lubricant compounds but preferably with one or more polyoxyalkylene compounds selected from the group consisting of prior art compounds having the formulas: ##STR2## R is individually selected from alkyl groups of 1 to about 21 carbo…
