(57) [Abstract] [Purpose] To provide a method for inexpensively producing a polyester wrinkle fabric excellent in wrinkle rising property. [Structure] Polyester is melt-spun, and after the following oil agent is applied, polyester fibers that have been stretch-heat set to have a boiling water shrinkage ratio of 5% or less are woven into yarns that have undergone strong twisting and sizing, and are then textured. do. Oil agent: A liquid fatty alcohol ester having a molecular weight of 550 to 750, B liquid aromatic ester represented by the following formula, C liquid triglyceride alkylene oxide adduct, provided that W A + W B = 20 to 25 W C = 2 to 15 W A / W B = 9 5 / 5-60 / 40 (R 1 and R 2 are alkyl groups having 8 to 25 carbon atoms, A is an alkylene group having 2 to 4 carbon atoms, and n and m are 1 or 2) |
