no. 1 Embodiment approach

[0035] First, 1st Embodiment of the processing agent for synthetic fibers (henceforth a processing agent) which actualized this invention is demonstrated. The processing agent of this embodiment is a processing agent for synthetic fibers containing a specific smoothing agent, a nonionic surfactant, a specific ionic surfactant, and a specific hydroxyl compound.

[0036] The smoothing agent is a thing containing at least 1 type of ester compound selected from the ester compound which consists of a polyhydric alcohol and a monocarboxylic acid, and the ester compound which consists of a monohydric alcohol and a polycarboxylic acid.

[0037] The ionic surfactant is one containing a sulfonic acid compound shown in Formula 2 below.

no. 2 Embodiment approach

[0057] A second embodiment of the actual synthetic fiber of the present invention will be described. The synthetic fiber of this embodiment is the synthetic fiber to which the processing agent of 1st Embodiment adhered. Specific examples of synthetic fibers are not particularly limited, and examples include (1) polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate, and polylactate; (2) nylon 6, Polyamide fibers such as nylon 66, (3) polyacrylic fibers such as polyacrylic acid and modified acrylonitrile, (4) polyolefin fibers such as polyethylene and polypropylene, etc.

[0058] The amount of the treatment agent (excluding the solvent) of the first embodiment attached to the synthetic fibers is not particularly limited, but the treatment agent of the first embodiment is preferably attached in a ratio of 0.1 to 3% by mass to the synthetic fibers. In addition, known methods such as a drum oiling method, a pilot oiling method using a metering pump, a...

Abstract

The processing agent for synthetic fibers of this invention contains the following smoothing agent, a nonionic surfactant, the following ionic surfactant, and the following hydroxy compound, It is characterized by the above-mentioned. A smoothing agent is at least 1 sort(s) of ester compound chosen from the ester compound which consists of a polyhydric alcohol and a monocarboxylic acid, and the ester compound which consists of a monohydric alcohol and a polycarboxylic acid. An ionic surfactant is an ionic surfactant containing a specific sulfonic acid compound. The hydroxy compound is at least one hydroxy compound selected from polyhydric alcohols having 2 to 6 carbon atoms, and at least one hydroxy compound selected from monohydric alcohols having 1 to 15 carbon atoms.

Description

technical field [0001] The present invention relates to a treatment agent for synthetic fibers capable of exhibiting excellent process passability in the yarn-making step of synthetic fibers, thereby improving production efficiency, and synthetic fibers to which the treatment agent is attached. Background technique [0002] In general, in the yarn-making process of synthetic fibers, from the viewpoint of reducing friction and preventing fiber damage such as yarn breakage, a synthetic fiber treatment containing a surfactant may be applied to the surface of the synthetic fiber filaments. agent treatment. [0003] Conventionally, for example, the processing agents for synthetic fibers disclosed in Patent Documents 1 to 4 are known. Patent Document 1 discloses a treatment agent for synthetic fibers containing an alkylene glycol or the like. Patent Document 2 discloses a treatment agent for synthetic fibers containing polyhydric alcohols, hydroxycarboxylic acids, and the like. ...
