PURPOSE:To provide the spinning oil preventing the breakage of fibers in high speed ring fine spinning processes, having an excellent counter-metal abrasion preventing property and enabling to prepare the fibers having high qualities by containing a specific organic phosphoric acid ester and an oxyalkylene polymer in specified amounts. CONSTITUTION:The objective oil contains (A) 5-80wt.% (in the solid components of the oil) of an organic phosphoric acid ester of formula I [M<+> is alkali metal ion, ammonium ion or amide ion; X<-> is the ion of an organic phosphoric acid of formula II (R1 is 8-22C alkyl or alkenyl; A is 2-4C alkylene; a is 0-22; b is 1 or 2)] and (B) 5-70wt.% of an oxyalkylene polymer of formula III (R11 is H, 1-20C alkyl, alkenyl, 2-22C acyl, polyhydric alcohol, etc.; A is 2-4C alkylene; the mol.wt. of the oxyalkylene polymer is 2000-40000). The oil is applied e.g. in a form of emulsion to polyester fibers, etc., to prevent the breakage of the fibers when subjected to a high speed fine spinning process and prevent the deterioration of the qualities of the fibers. |
