A spin-finish oil for a thermoplastic synthetic filament is provided to improve a friction property relating to metal and to have a superior adhesion property. The diesterifying of a linear diacid compound is performed by means of a fatty alcohol including an added alkylene oxide so that diacid diesterified compounds are produced and then one of the diacid diesterified compounds is selected. Multivalent alcohol ester compound is included within the spinning emulsion. The content of the one selected in the diacid diesterified compounds is 20-50 weight %. The mole number of alkylene oxide included to the fatty alcohol is 4 -22 mol. |
