WOUND BODY AND WOUND BODY MANUFACTURING METHOD

WIPO Patent Application WO/2020/050156

A1

The purpose of the invention is to provide a combined filament yarn wound body and a wound body manufacturing method that can effectively prevent fraying and slackening and prevent disturbing or breaking lower layers when winding or using a combined filament yarn. Provided is a wound body that has a core and a combined filament yarn traversely wound on the core, wherein: the combined filament yarn is traversely wound on the core in two or more directions; and when the wound body is placed on a white substrate in a space shielded from light so that the cylindrical direction of the core is erect, and light is irradiated toward a plane that includes the central axis of the cylinder from a point that is moved a distance of the radius of the core + 180 cm from the intersection point of the central axis of the core and the white substrate on the white substrate face in a direction perpendicular to the central axis and further moved 210 cm in a direction perpendicular to the substrate face of the white substrate, a number of linear reflection lines equal to the number of traverse winding directions is formed on the surface of the combined filament yarn being traversely wound.
