ABSTRACT OF THE DISCLOSURE: Lubricants, or processing aids, for synthetic fibers, particularly polyester and nylon fibers and most particularly for polyester fibers, are disclosed comprising a heteric polyoxyalkylene monoester condensation product capable of volatilizing at 200°C and having the formula: Image in which R is an aliphatic group having about 7 to about 22 carbon atoms; A is a mixture of oxyethylene and oxypropylene residues derived from the reaction of ethylene oxide and 1, 2- propylene oxide in the respective ratio by weight of 3:7 to 4:1; n has a value to produce a molecular weight of about 300 to about 3000 and R' is the residue of a monofunctional compound containing an OH group and having 1 to about 21 carbons in the alkyl chain. Certain embodiments of the invention are particularly suited by their low viscosity for application to synthetic textile fibers or yarn without dilution in water. Unexpectedly, the fiber lubricants, or processing aids, of the invention volatilize without leaving a residue when they contact heated metal surfaces during the fiber processing operation and are characterized by smoke points of 160°C or above.
