Patent ID: 10900146

Abstract:
The glass-fiber-yarn joined body 1 is provided with glass fiber yarns 2, 3, and a connection 5 in which a resin yarn 4 is wound around ends of both of the glass fiber yarns 2, 3, the ends being superimposed with each other. The connection 5 has a width W1 of 20 to 40 mm. When a connection diameter R as a total of diameters of the respective glass fiber yarns 2, 3 and the thickness of the resin yarn 4 wound around the connection 5 is 500 to 5000 μm and a mass of each of the glass fiber yarns 2, 3 is 200 to 6000 tex, a value of a ratio of mass of each of the glass fiber yarns 2, 3 relative to the connection diameter R is in the range of 0.32 to 2.00.
