The treating agent of embodiment 1 is attached to the synthetic fibers of the present embodiment. The form of the treating agent in attaching the treating agent to the synthetic fibers may be a diluted solution diluted with a diluting solvent, or may be an organic solvent solution or an aqueous solution. The synthetic fiber of the present embodiment is produced through the following steps: the treating agent is attached to the synthetic fibers in the form of a diluted solution such as an aqueous solution in, for example, a spinning or drawing step. The water may be evaporated from the diluent adhering to the synthetic fibers by a drying process.

Synthesis of 2-propylheptyl oleate (A1-1)
282g (1 mol) of oleic acid and 158g (1 mol) of 2-propylheptanol were put in a flask, and after melting at 75 ℃ under nitrogen, 0.6g of p-toluenesulfonic acid was added as a catalyst, and the reaction was further carried out at 120 ℃ under a reduced pressure of 2mmHg for 4 hours. Then, the temperature was returned to normal pressure under nitrogen at 105 ℃ and the catalyst was removed by adding an adsorbent. Filtration was then carried out at 90 ℃ to obtain a mixture comprising the esters A1-1.
In order to separate a trace amount of impurities (by-products, unreacted alcohols, unreacted fatty acids, etc.) from the ester A1-1 obtained by the above-mentioned method, a separation treatment was carried out by a column chromatography using silica gel.
The ester A1-1 separated by column chromatography was analyzed by 1H-NMR (MERCURY plus NMR Spectrometor System, manufactured by VALIAN corporation, 300MHz, CDCl 3). It was confirmed by NMR that the peak at 3.9 to 4.1ppm was doubled, that is, X in formula 31Is a peak of a hydrocarbon group (wherein X is1Triplet in the case of hydrogen atom). Further, it was confirmed by GC-MS measurement that MS had a molecular ion peak (m/z 422).

Test Classification 2 (evaluation of treating agent)
Production of drawn yarn
A predetermined amount of ion-exchanged water was added to each of the aqueous liquids obtained as described above, and the aqueous liquids were uniformly mixed to prepare an emulsion having a concentration of the treating agent of 10%. Pellets of polyethylene terephthalate having an inherent viscosity of 0.64 and a titanium oxide content of 0.2% were dried by a conventional method, and then spun at 295 ℃ using an extruder. After discharged from the nozzle and cooled to harden, the emulsion was attached to the moving yarn by an oil-feeding method using a metering pump so that the treating agent was 1.0% with respect to the moving yarn. Then, the filaments were bundled by a guide and drawn at a speed of 1400 m/min by a drawing roll heated to 90 ℃ and then drawn between the drawing roll and a drawing roll rotating at a speed of 4800 m/min by a factor of 3.2 to produce 83.3dtex (75 denier) 36filament drawn yarns. Yarn sway was evaluated by spinning fuzz and yarn breakage using the produced drawn yarn. In addition, tar of the treating agent was evaluated by the following method. The results are shown in tables 3 and 4.
Evaluation of spun fluff
The coil of the drawn yarn obtained in the above-described manner was wound at a yarn speed of 500 m/min for 10 minutes in an atmosphere of 25 ℃ X65% RH.
Evaluation of pile
In this case, the number of the spun yarn before winding was measured for 10 minutes by a yarn counting device (trade name DT-105, manufactured by Toray engineering Co., Ltd.) and the spun yarn was evaluated by the following evaluation criteria. The results are shown in the columns of "spun nap" in tables 3 and 4.
Excellent (good): the number of the fluff in 10 minutes is 0 to 3
O (acceptable): the number of the fluff in 10 minutes is 4-6
X (bad): the number of fluff in 10 minutes is 7 or more
Evaluation of yarn breakage
The drawn yarn was taken up for 24 hours during the production thereof. The number of yarn breakage at 24-hour winding was measured and the yarn breakage was evaluated by the following evaluation criteria. The results are shown in tables 3 and 4, column "spinning and yarn breaking".
Evaluation of broken yarn
Excellent (good): the number of filament breakage in 24 hours is 0
O (acceptable): the number of filament breakage in 24 hours is 1-4
X (bad): the number of broken filaments in 24 hours is more than 5
Evaluation of Tar
Tar was determined by the following method as a tar amount.
Tar content
2g of the treatment agent for synthetic fibers was taken out and heated on a hot plate heated to 220 ℃ for 24 hours. The quality after the heat treatment was measured and evaluated for the amount of tar according to the following evaluation criteria. The results are shown in "tar amount" columns of tables 3 and 4.
Excellent (good): the residue content after 24 hours is less than 40 percent
O (acceptable): the residue content after 24 hours is more than 40 percent and less than 60 percent
X (bad): the residue content after 24 hours is more than 60 percent
As is clear from the results in tables 3 and 4, the evaluations of the treating agents of the examples on the amount of tar and the fluff and yarn breakage in the spinning step were all the more satisfactory evaluations. According to the present invention, tar can be reduced and yarn chatter can be reduced.
