Patent ID: 11834294

Abstract:
Provided is a wound body of a commingled yarn, the wound body being capable of effectively suppressing fraying and sagging, disorder of a lower layer, or breakage of the commingled yarn during winding or use. Also provided is a method for manufacturing the wound body. The wound body contains a core member and a commingled yarn traversely wound onto the core member; wherein the commingled yarn is traversely wound onto the core member in two or more directions; and when the wound body is placed on a white substrate in a light-shielded space such that a cylindrical direction of the core member is upright, and light is irradiated toward a plane that includes a center axis of the cylinder, from a point that is moved a distance of a radius of the core member plus 180 cm in a direction perpendicular to the center axis from an intersection point between the center axis of the core member and the white substrate on a surface of the white substrate, and is further moved 210 cm in a direction perpendicular to the substrate face of the white substrate, linear reflection lines of a quantity equivalent to the number of directions of the traverse winding are formed on a surface of the traversely wound commingled yarn.
