Abstract: A textile treating composition, consisting of a mixture of a major amount of lubricant and a minor amount of a stabilizer of said lubricant and a process for employment thereof.

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.

Abstract: There are disclosed oxidation stable heteric or block copolymer polyoxyalkylene compositions suitable for the treatment of thermoplastic fibers, particularly polyester and nylon fibers, prior to the processing of such fibers in conventional processes to impart false twist, or to produce textured yarn or other type yarns by mechanical heat treatment and tensioning processes. The polyoxyalkylene compounds of the invention derived from lower alkylene oxides can be initiated with a difunctional aromatic compound containing reactive hydrogens such as a dihydroxyphenol to obtain an aromatic nucleus in the polymer chain and are capped on at least one end of the chain with an alpha-olefine epoxide or mixtures thereof with at least one aliphatic monocarboxylic acid. Hydroxyl functionality can be retained on one end of the molecule.

Abstract: Polyesters are prepared by the reaction of an alkyl ester of a dicarboxylic acid and certain polyoxyalkylated polyols having the formula: ##STR1## wherein x and y are integers such that the oxyethylene content of the polyol is between 10% and 90% by weight and the oxypropylene content of the polyol is between 90% and 10% by weight. The polyesters are particularly useful in the preparation of antistatic polymer compositions.
