When the amount of the silicone oil adhered is 0.02% by weight or more, sufficient slipperiness can be imparted to the artificial hair fiber. When the amount of the silicone oil adhered is 0.5% by weight or less, the stickiness of the artificial hair fibers is suppressed. Specifically, the amount of silicone oil adhered 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% by weight, which may be in the range between any two of the values exemplified here.

　人工毛髪用繊維として、塩化ビニル系繊維、ポリエステル系繊維、ポリアミド系繊維が挙げられる。人工毛髪用繊維は、溶融紡糸工程、延伸工程、アニール工程を経て、製造される。溶融紡糸工程では、樹脂組成物を溶融紡糸することによって未延伸糸を製造する。具体的には、一軸押出機、二軸押出機、ロール、バンバリーミキサー、ニーダー等を用い、ポリ塩化ビニル系樹脂、ポリエステル系樹脂又はポリアミド系樹脂と、必要に応じて、熱安定剤、滑剤、難燃剤、紫外線吸収剤等の各種配合剤を溶融混錬し、通常の溶融紡糸法で溶融紡糸する。このとき、繊度をコントロールしながら、引き取り速度を調整することで、未延伸糸が得られる。 Examples of fibers for artificial hair include vinyl chloride fibers, polyester fibers, and polyamide fibers. The artificial hair fiber is manufactured through a melt spinning step, a drawing step, and an annealing step. In the melt spinning step, an undrawn yarn is produced by melt spinning the resin composition. Specifically, using a single-screw extruder, a twin-screw extruder, a roll, a Banbury mixer, a kneader, etc., a polyvinyl chloride resin, a polyester resin, or a polyamide resin, and if necessary, a heat stabilizer, a lubricant, etc. Various compounding agents such as flame retardants and ultraviolet absorbers are melt-kneaded and melt-spun by a normal melt-spinning method. At this time, an undrawn yarn can be obtained by adjusting the take-up speed while controlling the fineness.
　延伸工程では、得られた未延伸糸を延伸倍率１．５～５．０倍で延伸して延伸糸を製造する。延伸倍率は、２．０～４．０倍が好ましい。延伸倍率は、適度に大きい方が繊維の強度発現が適度に起こる傾向にあり、適度に小さい方が延伸処理時に糸切れを発生し難くなる傾向にあるためである。 In the drawing step, the obtained undrawn yarn is drawn at a drawing ratio of 1.5 to 5.0 times to produce a drawn yarn. The draw ratio is preferably 2.0 to 4.0 times. This is because when the draw ratio is appropriately large, the strength of the fiber tends to be developed appropriately, and when the draw ratio is appropriately small, the yarn breakage tends to be less likely to occur during the drawing treatment.
　延伸処理の際の温度は、８０～１２０℃が好ましい。延伸処理温度があまりに低いと繊維の強度が低くなると共に糸切れを発生し易くなる傾向にあり、あまりに高いと得られる繊維の触感がプラスチック的な滑り触感になる傾向にあるためである。 The temperature during the stretching treatment is preferably 80 to 120 ° C. This is because if the drawing treatment temperature is too low, the strength of the fibers tends to be low and yarn breakage tends to occur, and if the drawing treatment temperature is too high, the tactile sensation of the obtained fibers tends to be a plastic-like slippery feel.
　アニール工程では、延伸糸に対して好ましくは１００～２００℃の熱処理温度で熱処理を行う。この熱処理によって、延伸糸の熱収縮率を低下させることができる。熱処理は、延伸処理の後に連続して行っても、一旦巻き取った後に時間を開けて行うこともできる。 In the annealing step, the drawn yarn is preferably heat-treated at a heat treatment temperature of 100 to 200 ° C. By this heat treatment, the heat shrinkage rate of the drawn yarn can be reduced. The heat treatment may be carried out continuously after the stretching treatment, or may be carried out with a time after being wound once.
　人工毛髪用繊維の単繊度は、２０～１００デシテックスが好ましく、より好ましくは３５～８０デシテックスである。この単繊度にするためには、溶融紡糸工程直後の繊維（未延伸糸）の繊度を３００デシテックス以下にしておくことが好ましい。未延伸糸の繊度が小さければ、細繊度の人工毛髪用繊維を得るために延伸倍率を小さくすることができ、延伸処理後の人工毛髪用繊維に光沢が発生し難くなる。 The single fiber degree of the artificial hair fiber is preferably 20 to 100 decitex, more preferably 35 to 80 decitex. In order to achieve this single fineness, it is preferable that the fineness of the fiber (undrawn yarn) immediately after the melt spinning step is 300 decitex or less. If the fineness of the undrawn yarn is small, the draw ratio can be reduced in order to obtain fibers for artificial hair with fineness, and the fibers for artificial hair after the drawing treatment are less likely to be glossy.
　人工毛髪用繊維は、（１）塩化ビニル系樹脂から形成される人工毛髪用繊維、又は、（２）ポリアミド系樹脂から形成される人工毛髪用繊維が好ましい。塩化ビニル系樹脂は、塊状重合、溶液重合、懸濁重合、乳化重合等によって得られたものであり、繊維の初期着色性等を勘案して、懸濁重合によって製造したものが好ましい。塩化ビニル系樹脂とは、塩化ビニルの単独重合物であるホモポリマー樹脂又は各種のコポリマー樹脂、及びそれらの混合物である。コポリマー樹脂としては、塩化ビニル－酢酸ビニルコポリマー樹脂、塩化ビニル－プロピオン酸ビニルコポリマー樹脂等の塩化ビニルとビニルエステル類とのコポリマー樹脂、塩化ビニル－アクリル酸ブチルコポリマー樹脂、塩化ビニル－アクリル酸２エチルヘキシルコポリマー樹脂等の塩化ビニルとアクリル酸エステル類とのコポリマー樹脂、塩化ビニル－エチレンコポリマー樹脂、塩化ビニル－プロピレンコポリマー樹脂等の塩化ビニルとオレフィン類とのコポリマー樹脂、塩化ビニル－アクリロニトリルコポリマー樹脂等がある。コポリマー樹脂において、コモノマーの含有量は、成型加工性、糸特性等の要求品質に応じて決めることができる。塩化ビニル系樹脂は、好ましくは、塩化ビニル樹脂、塩化ビニル樹脂と塩素化塩化ビニル樹脂の混合物、塩化ビニル―アクリロニトリルコポリマーのうちの１種、ないし２種以上の混合物である。 The artificial hair fiber is preferably (1) an artificial hair fiber formed of a vinyl chloride resin or (2) an artificial hair fiber formed of a polyamide resin. The vinyl chloride resin is obtained by bulk polymerization, solution polymerization, suspension polymerization, emulsion polymerization or the like, and is preferably produced by suspension polymerization in consideration of the initial colorability of the fiber or the like. The vinyl chloride resin is a homopolymer resin which is a homopolymer of vinyl chloride, various copolymer resins, and a mixture thereof. Examples of the copolymer resin include a copolymer resin of vinyl chloride and vinyl esters such as vinyl chloride-vinyl acetate copolymer resin and vinyl chloride-vinyl propionate copolymer resin, vinyl chloride-butyl acrylate copolymer resin, and vinyl chloride-2 ethylhexyl acrylate. There are copolymer resins of vinyl chloride and acrylic acid esters such as copolymer resins, vinyl chloride-ethylene copolymer resins, copolymer resins of vinyl chloride and olefins such as vinyl chloride-propylene copolymer resins, vinyl chloride-acrylonitrile copolymer resins and the like. ..
