TREATMENT AGENT FOR SPINNING POLYESTER SYNTHETIC FIBER, TREATMENT METHOD OF POLYESTER SYNTHETIC FIBER AND POLYESTER SYNTHETIC FIBER

摘要

PROBLEM TO BE SOLVED: To provide a treatment agent for spinning a polyester synthetic fiber sufficiently responding to speeding up of a spinning process recently and satisfying web uniformity in a high speed carding process, roller winding resistance in a high speed ring drawing process, scum deposition resistance and coil foaming property, scum deposition resistance in a high speed ring spinning process and scum deposition resistance in a high speed rotor open end process at the same time, a treatment method of the polyester synthetic fiber using the treatment agent and a polyester synthetic fiber obtained by the treatment method.SOLUTION: One containing a specific alkyl phosphoric acid ester alkali metal salt having 12 to 22 carbon atoms in a molecule of 10 to 90 mass%, a specific surfactant of 5 to 80 mass% and a specific alkyl phosphoric acid ester amine salt having 12 to 22 carbon atoms of 0.1 to 45 mass% (total 100 mass%) is used as a treatment agent for spinning a polyester synthetic fiber.SELECTED DRAWING: None
