A yarn treating composition useful for application to a filamentary yarn for high-speed friction draw-false twisting. This composition comprises substantially a polyether having a molar copolymerization ratio between propylene and ethylene oxides of 35:65--90:10 and an average molecular weight of 1,000 to 15,000, and small amounts of anionic compounds. The anionic compounds are used in the form of a mixture of salts of specific dicarboxylic acid derivatives with phosphate compounds and/or sulfonate compounds. The application of said treating composition to yarns provides a reduction of fluctuation in friction between the yarns and rollers, guides, etc. and of frictional resistance at a high running speed, improvement in threading property in false twisting, and a sharp decrease in scum deposits on heaters.
