Examples of the anion of the ionic liquid include a halogen-based ion, a boron-based ion, a phosphorus-based ion, and a sulfonic acid anion. Moreover, when the silicone oil is an amino-modified silicone oil, it is preferable that an ionic liquid has an amino ion as a cation from a viewpoint of compatibility and dispersibility.

It is preferable that it is more than 0.5 weight part and 9.5 weight part or less, and, as for content of silicone oil with respect to 100 weight part of water, it is more preferable that it is 1.5-7.0 weight part. When the content of the silicone oil is more than 0.5 parts by weight, it becomes possible to impart sufficient slipperiness to the fiber for artificial hair. When the content of the silicone oil is 9.5 parts by weight or less, it becomes possible to sufficiently suppress the stickiness of the fibers for artificial hair. The content of the silicone oil with respect to 100 parts by weight of water is specifically, for example, 0.6, 0.7, 0.8, 0.9, 1.0, 1.5, 2.0, 2.5, 3.0, 3.2, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0. , 6.5, 7.0, 7.5, 7.9, 8.0, 8.5, 9.0, 9.5 parts by weight, and may range between any two values exemplified herein.

When the content of the ionic liquid is 0.2 parts by weight or more, it becomes possible to impart sufficient antistatic properties to the fibers for artificial hair. When the content of the ionic liquid is 5.0 parts by weight or less, it becomes possible to sufficiently suppress the stickiness of the fibers for artificial hair.

On the other hand, it is preferable that a fiber treatment agent does not contain a cationic active agent substantially. For example, it is preferable that content of a cationic active agent is 1 weight part or less with respect to 100 weight part of water, even if a fiber treatment agent contains no or contains a cationic active agent at all, and it is more preferable that it is 0.1 weight part or less. When a cationic activator is used instead of an ionic liquid to impart sufficient antistatic properties to fibers for artificial hair, stickiness may occur.

The fiber treatment agent is applied to the surface of fibers for artificial hair. The fiber for artificial hair after the fiber treatment agent is applied is used for hair decoration products such as wigs, hairpieces, blades, and extension hair. The hair decoration product in one Embodiment of this invention contains the fiber for artificial hair to which the said fiber treatment agent was apply|coated and the active ingredient adhered.

As a method of making the fiber treatment agent adhere to the fibers for artificial hair, a conventionally known means of applying a liquid to the fibers for artificial hair can be employed. For example, a means for winding the fiber for artificial hair on a roll with a fiber treatment agent attached to the surface, means for immersing the fiber for artificial hair in a liquid tank storing the fiber treatment agent, a brush, a brush, etc. There is a means for attaching a fiber treatment agent, and the like.

In the fiber treatment agent, the active ingredient, that is, the compound (silicone oil and ionic liquid) contained in the treatment agent is preferably adhered to the surface of the artificial hair fiber in a predetermined ratio. It is preferable that the total amount of silicone oil and ionic liquid adhered to the fiber for artificial hair is in the range of 0.03 to 1.0% by weight based on the weight of the fiber for artificial hair. When the adhesion amount of the active ingredient is less than 0.03% by weight, the effect of the fiber treatment agent cannot be expected, and there is a possibility that the effect on the antistatic property and the slip property cannot be obtained. Moreover, when the adhesion amount of an active ingredient exceeds 1.0 weight%, stickiness arises in the fiber for artificial hair, and the touch may worsen. Specifically, the sum of the adhesion amounts of the silicone oil and the ionic liquid is, for example, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 wt%, It may be in the range between any two numerical value among the numerical values exemplified in .

The adhesion amount of the silicone oil to the fibers for artificial hair is preferably 0.02 to 0.5% by weight based on the weight of the fibers for artificial hair. When the adhesion amount of the silicone oil is 0.02% by weight or more, sufficient slipperiness can be imparted to the fiber for artificial hair. When the adhesion amount of the silicone oil is 0.5% by weight or less, the stickiness of the fibers for artificial hair is suppressed. Specifically, the adhesion amount of the silicone oil is, for example, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 0.3, 0.4, 0.5 wt%, any two of the numerical values exemplified here It may be in the range between numerical values.

It is preferable that the adhesion amount of the ionic liquid to the fiber for artificial hair is 0.01 to 0.5 weight% with respect to the weight of the fiber for artificial hair. When the adhesion amount of the ionic liquid is 0.01% by weight or more, sufficient antistatic properties can be imparted to the fibers for artificial hair. When the adhesion amount of the ionic liquid is 0.5% by weight or less, stickiness of the fibers for artificial hair is suppressed. Specifically, the adhesion amount of the ionic liquid is, for example, 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 0.3, 0.4, 0.5 wt%, among the numerical values exemplified here It may be in the range between any two numerical values.

Examples of the fibers for artificial hair include vinyl chloride fibers, polyester fibers, and polyamide fibers. Fibers for artificial hair are manufactured through a melt spinning process, a drawing process, and an annealing process. In a melt spinning process, an undrawn yarn is manufactured by melt-spinning a resin composition. Specifically, using a single screw extruder, a twin screw extruder, a roll, a Banbury mixer, a kneader, etc., a polyvinyl chloride-based resin, a polyester-based resin, or a polyamide-based resin, and, if necessary, a heat stabilizer, a lubricant, a flame retardant , and various compounding agents, such as a UV absorber, are melt-kneaded, and melt-spinning is performed by a normal melt spinning method. At this time, undrawn yarn can be obtained by adjusting the take-up speed while controlling the fineness.

In the stretching step, the obtained undrawn yarn is drawn at a draw ratio of 1.5 to 5.0 to prepare a drawn yarn. As for a draw ratio, 2.0-4.0 times are preferable. This is because, as for the draw ratio, when it is moderately large, the strength expression of the fiber tends to occur moderately, and when the one where the draw ratio is moderately small, it tends to become difficult to generate|occur|produce yarn breakage at the time of a drawing process.

As for the temperature at the time of an extending|stretching process, 80-120 degreeC is preferable. This is because, when the drawing treatment temperature is too low, the strength of the fiber decreases and yarn breakage tends to occur easily, and when the drawing temperature is too high, the resulting fiber tends to have a plastic and slippery feel.

In the annealing process, the drawn yarn is preferably heat-treated at a heat treatment temperature of 100 to 200°C. By this heat treatment, the thermal contraction rate of the drawn yarn can be reduced. Heat treatment may be performed continuously after an extending|stretching process, and after winding up once, it may be performed over time.

As for the single fineness of the fiber for artificial hair, 20-100 decitex is preferable, More preferably, it is 35-80 decitex. In order to set it as this single fineness, it is preferable to set the fineness of the fiber (undrawn yarn) immediately after a melt spinning process to 300 decitex or less. When the fineness of the undrawn yarn is small, the draw ratio can be made small in order to obtain fibers for artificial hair of fineness, and it becomes difficult to generate gloss in the fibers for artificial hair after the stretching treatment.

The fiber for artificial hair is preferably (1) a fiber for artificial hair formed from a vinyl chloride-based resin, or (2) a fiber for artificial hair formed from a polyamide-based resin. Vinyl chloride-based resin is obtained by block polymerization, solution polymerization, suspension polymerization, emulsion polymerization, etc., and it is preferable to manufacture by suspension polymerization in view of the initial stage coloring property of a fiber, etc. The vinyl chloride-based resin is a homopolymer resin, which is a homopolymer of vinyl chloride, or various copolymer resins, and mixtures thereof. As the copolymer resin, a copolymer resin of vinyl chloride and vinyl esters such as vinyl chloride-vinyl acetate copolymer resin, vinyl chloride-vinyl propionate copolymer resin, vinyl chloride-butyl acrylate copolymer resin, vinyl chloride-vinyl acrylate 2ethyl Copolymer resin of vinyl chloride and acrylic acid esters such as hexyl copolymer resin, vinyl chloride-ethylene copolymer resin, vinyl chloride-propylene copolymer resin, etc. copolymer resin of vinyl chloride and olefins, vinyl chloride-acrylonitrile copolymer resins and the like. In the copolymer resin, the content of the copolymer can be determined according to required qualities such as molding processability and yarn properties. The vinyl chloride-based resin is preferably a mixture of one to two or more of a vinyl chloride resin, a mixture of a vinyl chloride resin and a chlorinated vinyl chloride resin, and a vinyl chloride-acrylonitrile copolymer.

The polyamide-based resin includes nylon 6, nylon 66, nylon 11, nylon 12, nylon 6·10, nylon 6·12, or a copolymer thereof. Preferably, it is nylon 6, nylon 66, and a copolymer of nylon 6 and nylon 66.
