This invention relates to an improved method for ply-twisting nylon yarns at twisting speeds greater than 6000 rpm. More particularly, the invention involves coating the nylon fibers with less than about 1 % by weight of finish containing an alkyl poly-oxyalkylene carboxylate ester lubricant composition. The resulting ply-twisted yarn is especially suitable for use as pile in carpets.
