摘要
The present invention forms meshes between intersections of synthetic fiber cords while the synthetic fiber cords having a form in which a plurality of synthetic fiber filaments are plied and twisted is crossed in a knotless type, wherein a diameter (d) of the synthetic fiber cord satisfies the Equation (I), a maximum distance (D1) between the intersections adjacent to each other satisfies the Equation (II), and a minimum distance (D2) between the intersections adjacent to each other satisfies the Equation (III).;Since the present invention is made lightweight with a lower areal density than a conventional protective net for sports and increases rate of hole size with a small diameter of the synthetic fiber cord constituting the protective net, the present invention improves resistance against wind during manufacture of a protective net structure, and has excellent mechanical properties and thus provides excellent resistance against impact applied when a ball flies and bumps. Consequently, the present invention minimizes damage and extends a replacement cycle.;Further, the present invention improves visibility with the high rate of hole size, and also improves stability by effectively preventing penetration of the ball between the meshes.;Further, the present invention is easily mounted in the protective net structure and provides excellent flame retardancy and weather resistance.
