Furthermore, the fourth treatment agent of the fourth dosage form can also be distributed separately from the first to third treatment agents of the fourth dosage form.

[0158] <Ninth Implementation> Next, a ninth embodiment of the present invention, namely a polyester synthetic fiber (hereinafter referred to as "synthetic fiber"), will be described. The synthetic fiber of this embodiment has the treatment agent of the first embodiment attached to its surface. Specifically, this embodiment provides a pre-treated synthetic fiber comprising the synthetic fiber and the treatment agent attached thereto. By attaching the treatment agent to the surface of the synthetic fiber, synthetic fibers endowed with various functions can be obtained.

[0159] When using the treatment agent of formulation 1, the synthetic fibers of this embodiment can be obtained by applying a diluent containing a solvent and the treatment agent of the first embodiment to the synthetic fibers. The diluent can be prepared, for example, by adding the treatment agent of the first embodiment or a composition containing the treatment agent to the solvent.

[0160] When using a three-component treatment agent, the synthetic fiber treatment method of this embodiment is characterized by applying a diluted solution containing a solvent, a three-component first treatment agent of the second embodiment, a three-component second treatment agent of the third embodiment, and a three-component third treatment agent of the fourth embodiment to the synthetic fiber. The preferred ratio of the three-component first treatment agent, the three-component second treatment agent, and the three-component third treatment agent is the mass ratio of non-volatile components: three-component first treatment agent: three-component second treatment agent: three-component third treatment agent = (5~60):(30~90):(0.05~25). By limiting this range, operability can be improved. In this specification, non-volatile components refer to the mass of the absolutely dry matter obtained after heat-treating the object at 105°C for 2 hours to fully remove volatile substances.

[0161] When using a four-component treatment agent, the synthetic fiber treatment method of this embodiment is characterized by applying a diluent containing a solvent, a four-component first treatment agent of the fifth embodiment, a four-component second treatment agent of the sixth embodiment, a four-component third treatment agent of the seventh embodiment, and a four-component fourth treatment agent of the eighth embodiment to the synthetic fiber. The preferred ratio of the four-component first treatment agent, four-component second treatment agent, four-component third treatment agent, and four-component fourth treatment agent is the mass ratio of non-volatile components: four-component first treatment agent: four-component second treatment agent: four-component third treatment agent: four-component fourth treatment agent = (3~25):(30~90):(3~50):(0.05~25). By limiting it to this range, operability can be improved.

[0162] The solvent used to manufacture the diluent can be exemplified by that shown in the first embodiment. From the viewpoint of operability, the concentration of the treatment agent in the diluent is preferably 0.1% by mass or more and 10% by mass or less.

[0163] The diluted solution obtained by the above method will be applied to the synthetic fiber in at least one of the following steps: spinning, stretching, and post-processing steps of the synthetic fiber.

[0164] Synthetic fibers subjected to a diluent include polyester synthetic fibers. Specific examples of polyester synthetic fibers include polyethylene terephthalate (PET), polyethylene terephthalate, polyethylene terephthalate, polyethylene naphthalate, polylactic acid, and composite fibers containing these polyester resins.

[0165] The uses of synthetic fibers are not particularly limited, and examples include spinning, yarn manufacturing, non-woven fabrics, filling, and papermaking. The length of the fibers is not particularly limited; both short and long fibers can be used. Short fibers generally refer to those called "staples," excluding long fibers called "filaments." Furthermore, the length of short fibers is not particularly limited as long as it meets the definition of short fibers in this technical field, for example, 100 mm or less, preferably 30 mm to 70 mm. Among these, the processing agent of the present invention is preferably suitable for polyester short fibers and polyester-based synthetic fibers used in yarn manufacturing.

[0166] There are no particular limitations on the proportion of the treatment agent adhering to the synthetic fibers. Preferably, the diluent adheres to the synthetic fibers such that the final non-volatile component is 0.01% to 10% by mass, more preferably 0.1% to 3% by mass. This composition effectively utilizes the properties of each component. Furthermore, there are no particular limitations on the method of adhering the diluent. Known methods can be used depending on the type, form, and application of the synthetic fibers, such as roller oiling, metering pump-guided oiling, impregnation oiling, and spray oiling. When using impregnation oiling, the impregnation time is preferably 1 minute to 5 minutes.

[0167] Synthetic fibers treated with a diluent can also be dried or heated using known methods. Drying or heating causes solvents such as water to evaporate, resulting in fibers coated with components contained in the treatment agent.

[0168] (Effects of this implementation method) The effects of the synthetic fiber in the ninth embodiment will be explained. In addition to the effects of the embodiments described above, the ninth embodiment also has the following effects.

[0169] (9-1) The synthetic fiber of the ninth embodiment is coated with the treatment agent of the first embodiment. Therefore, the stickiness of the synthetic fiber surface can be reduced, and the smoothness and antistatic properties can be improved. In this way, the manufacturing characteristics of the fiber and the quality of the obtained fiber can be improved.

[0170] (Example of Change) The above-described embodiments can also be modified as follows. The above-described embodiments and the following modifications can be combined and implemented within the scope of technical non-contradiction.

[0171] • Without impairing the effects of the present invention, the treatment agents, components, or diluents described in the above embodiments may be further combined with other solvents, stabilizers, antistatic agents, adhesives, antioxidants, UV absorbers, surfactants other than those mentioned above, and other components commonly used in treatment agents to maintain the quality of the treatment agents, components, or diluents. From the viewpoint of effectively utilizing the performance of the present invention, the content of the aforementioned components other than solvents is preferably 10% by mass or less in each treatment agent. Furthermore, the aforementioned other components and the aforementioned treatment agents may be stored separately.

[0197] Test Category 2 (Antistatic Properties)

[0198] The treatment agents described in the Examples and Comparative Examples in Tables 1 and 2 were applied to untreated polyester cotton (1.2 de × 38 mm) with an application amount of 0.15% relative to the polyester cotton. The polyester cotton with the treatment agent was dried in a dryer at 80°C for 2 hours, and then conditioned overnight at 25°C × 40%RH. 10 kg of the treated polyester cotton was passed through a carding machine (manufactured by Howa Kogyo Co., Ltd.) at 25°C × 40%RH to obtain carded slivers. The carding web was visually inspected as it passed through the carding machine, and the antistatic properties were evaluated using the following criteria based on whether the carding web sagged due to static electricity. The results are shown in the "Antistatic Properties" column of Tables 1 and 2.

[0199] Evaluation criteria for antistatic properties 2 (Acceptable): No evidence of sagging of the carding net has been confirmed. 1 (Defect): Sagging of the carding web has been confirmed.

[0200] Test Category 3 (Low Adhesion)

[0201] 5g of each treatment agent was placed in a glass dish (9.5cm inner diameter) to allow it to spread evenly. The dish was then incubated at 30°C and 70% RH for 24 hours. The appearance of the treatment agent was then visually confirmed, and its properties were assessed by touch. Low tack was evaluated using the following criteria. The results are shown in the "Low Tack" column of Tables 1 and 2.

[0202] • Evaluation criteria for low adhesion 2 (Acceptable): The product has a solid appearance after temperature adjustment and does not feel sticky to the touch. 1 (Defect): After temperature adjustment, the product appears as a liquid or gel and feels sticky to the touch; or although it appears as a solid after temperature adjustment, it feels sticky to the touch.

[0203] Test Category 4 (Smoothness)

[0204] The carded slivers obtained in test category 2 were observed using a scanning electron microscope (manufactured by Nippon Electron). Ten or more polyester fibers constituting the carded slivers were observed, and smoothness was evaluated using the following criteria based on the number of frictional damage observed on the fiber surface. The results are shown in the "Smoothness" column of Tables 1 and 2.

[0205] • Evaluation criteria for smoothness 2 (Fair): Friction damage to the fiber surface is less than 3 per fiber on average. 1 (Defect): Friction damage to the fiber surface, averaging more than 3 per fiber.

[0206] Test Category 5 (Emulsion Stability)

[0207] Each treatment agent was diluted with warm water at approximately 70°C to prepare a 1% dilution. 100 mL of the prepared 1% dilution was allowed to stand at 50°C for 24 hours. The appearance of the diluted solution after standing was visually confirmed, and the emulsion stability was evaluated using the following criteria. The results are shown in the "Emulsion Stability" column of Tables 1 and 2.

[0208] • Evaluation criteria for emulsification stability 6 (Super Excellent): No precipitates or oil droplets were produced. 5 (Excellent): No oil droplets were produced, but some precipitates were formed. When stirred at 300 rpm with a stirring blade, the precipitates were dissolved within 10 seconds. 4 (Excellent): No oil droplets were produced, but some precipitates were formed. When stirred at 300 rpm with a stirring blade, the precipitates could be dissolved within 10 to 30 seconds. 3 (Good): No oil droplets were produced, but some precipitates were formed. When stirring with a stirring blade at 300 rpm, the precipitates could be dissolved within 30 to 60 seconds. 2 (Acceptable): No oil droplets were produced, but some precipitates were formed. When stirring with a stirring blade at 300 rpm, the precipitates can be dissolved within 30 to 90 seconds. 1 (Defect): Oil droplets or precipitates are produced, and the precipitates cannot be dissolved even after stirring at 300 rpm for more than 90 seconds with the stirring blade.

[0209] Comparing the evaluation results of the examples and comparative examples shown in the tables, it is clear that the treatment agent of the present invention can improve the emulsification stability when used as a water diluent. Furthermore, it can reduce the stickiness imparted by the treatment agent to the fiber surface and improve smoothness and antistatic properties.
