Summary:To provide a winding body for combined filament yarn capable of effectively suppressing fraying and sagging at a time when winding and using the combined filament yarn; disturbance of an underlayer; or cutting, and to provide a manufacturing method of the winding body thereof.SOLUTION: There are provided a core material and a winding body comprising combined filament yarn that is traverse-wound around the core material, the combined filament yarn is traverse-wound around the core material in at least two directions. According to the winding body, the winding body is arranged so as to make a cylindrical direction of the core material be upright on a white substrate inside a light-shielding space; a core material radius is moved by +180 cm in a direction perpendicular to a central axis from an intersection point of the white substrate and the central axis of the core material; and further, the number of linear reflection lines equal to that in the direction of being traverse-wound is formed on a surface of the combined filament yarn that is traverse-wound, when carrying out light irradiation from a 210 cm moving point in a direction perpendicular to a substrate surface of the white substrate so as to face a surface including the central axis of a cylinder.SELECTED DRAWING: None 【課題】混繊糸の巻き取り時や使用時のほつれやたるみ、下層の乱れ、あるいは切れを効果的に抑制することができる混繊糸の巻取体および巻取体の製造方法を提供する。【解決手段】芯材と、前記芯材に対し、トラバース巻きされた混繊糸を有する巻取体であって、前記混繊糸は、前記芯材に対し、２方向以上にトラバース巻きされており、遮光空間内の白色基板上に、前記巻取体を前記芯材の円筒方向が直立するように置き、前記白色基板面上であって、前記芯材の中心軸と前記白色基板の交点から中心軸に垂直な方向に芯材の半径＋１８０ｃｍ移動し、さらに、白色基板の基板面に垂直な方向に２１０ｃｍ移動した点から、前記円筒の中心軸を含む面に対向するように光照射したとき、前記トラバース巻きする方向と等しい数の直線状の反射線が前記トラバース巻きされた混繊糸の表面に形成される、巻取体。【選択図】 なし
