従来、塩化ビニル系樹脂は、耐候性、透明性、難燃性、耐薬品性に優れ、安価であることから典型的な汎用プラスチックとして、様々な用途に利用されている。その繊維は、強度、伸度、感触などが天然毛髪に近いことから、例えば、頭髪用カツラや人形頭髪などの人工毛髪用繊維として多く使用されている。 Conventionally, a vinyl chloride resin has been used in various applications as a typical general-purpose plastic because it is excellent in weather resistance, transparency, flame retardancy and chemical resistance and is inexpensive. The fiber is often used as a fiber for artificial hair such as hair wigs and doll hair because it is close to natural hair in strength, elongation, and feel.
しかし、更に天然毛髪に近似させるため、様々な繊維二次加工が施されるが、この結果として頭髪用カツラなどの加工工程において、必要以上に熱収縮してしまう課題がある。これを解決する手段として、塩化ビニル樹脂と塩素化塩化ビニル樹脂からなる塩化ビニル系繊維(特許文献1参照。)が提案されているが、この方法では多量の塩素化塩化ビニル樹脂を添加することが困難であり、十分な効果を得られない場合があった。 However, in order to further approximate natural hair, various fiber secondary processes are performed. As a result, there is a problem that heat shrinks more than necessary in a process such as a hair wig. As means for solving this problem, a vinyl chloride fiber composed of a vinyl chloride resin and a chlorinated vinyl chloride resin (see Patent Document 1) has been proposed. In this method, a large amount of chlorinated vinyl chloride resin is added. However, it was difficult to obtain a sufficient effect.

本発明に使用する塩化ビニル系樹脂の粘度平均重合度は、600〜2500が好ましく、600〜1800がより好ましい。塩化ビニル系樹脂の粘度平均重合度が600未満であると、溶融粘度が低下するため、得られる繊維が熱収縮しやすくなる恐れがある。一方、粘度平均重合度が2500を超えると、溶融粘度が高くなるためノズル圧力が高くなり安全な製造が困難になる恐れがある。尚、粘度平均重合度は、樹脂200mgをニトロベンゼン50mlに溶解させ、このポリマー溶液の比粘度を30℃恒温槽中において、ウベローデ型粘度計を用いて測定し、JIS―K6720−2により算出した値である。 600-2500 are preferable and, as for the viscosity average polymerization degree of the vinyl chloride-type resin used for this invention, 600-1800 are more preferable. When the viscosity average polymerization degree of the vinyl chloride resin is less than 600, the melt viscosity is lowered, so that the obtained fiber may be easily heat-shrinked. On the other hand, when the viscosity average degree of polymerization exceeds 2500, the melt viscosity becomes high, so that the nozzle pressure becomes high and it may be difficult to produce safely. The viscosity average degree of polymerization is a value calculated by JIS-K6720-2 by dissolving 200 mg of resin in 50 ml of nitrobenzene, measuring the specific viscosity of this polymer solution in a constant temperature bath at 30 ° C. using an Ubbelohde viscometer. It is.

When the melting point of the polylactic acid resin is less than 100 ° C., the heat resistance of the obtained fiber may be inferior. On the other hand, when the melting point exceeds 300 ° C., mixing with the vinyl chloride resin may be difficult.
The melting point of the polylactic acid- based resin is a temperature at which the peak of the heat of fusion is obtained when a sample is heated at a heating rate of 10 ° C./min in nitrogen using a differential scanning calorimeter (DSC). This is a value calculated according to JISK-7121.

Preferred polylactic acid resin in the present invention, one common optical purity is low, the crystallinity of the polylactic acid resin is reduced to, in particular known that the melting point is lowered. For this reason, those containing 70% or more, preferably 80% or more, particularly preferably 90% or more of L-form are used.
