PURPOSE:To obtain the title finishing oil maintaining excellent retention ratio of strength after heat treatment, to reduce contamination of spinneret and to improve yarn strength without adding an additive such as inhibitor of thermal degradation to a polymer, containing a metallic salt of specific organic acid. CONSTITUTION:The aimed finishing oil containing a compound (e.g. Cu octyldodecyl alcohol sesquiphosphate or Mn hexyldecyl alcohol sesquiphosphate) shown by the formula (R1 and R2 are H, alkali metal or 8-30C hydrocarbon and at least one of R1 and R2 is 8-30C hydrocarbon; M is Cu, Fe, Ni or Mn; n is valence of M; X is O or S). The amount of the compound shown by the formula added to the finishing oil is preferably 500-7,000ppm calculated as amount of metal atom. |
