そこで、本発明は、製造工程の追加を必要とせず、繊維の断面形状にも大きな制限を受けずに、人毛に近い低光沢、さらさら感を発現可能なポリ塩化ビニル樹脂系の人工毛髪用繊維、及び人工毛髪用繊維を使用した頭飾品を提供することを目的とする。 Therefore, the present invention does not require an additional manufacturing process, and is not limited to the cross-sectional shape of the fiber, and is used for artificial hair made of a polyvinyl chloride resin system that can express a low gloss and a smooth feeling similar to human hair.

（構成）
