Abstract
Abstract Lubricants, or processing aids, for synthetic fibers, particularly polyester and nylon fibers and most particularly for polyester fibers, are disclosed comprising a capped heteric polyoxyalkylene monoester 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 derived from a monofunctional compound containing an OH group, preferably a monofunctional aryl alcohol or a monofunctional alkyl or arylalkyl alcohol, all having 1 to about 21 carbons in the alkyl chain.
