Although the luminous soccer ball of Korean Utility Model Registration No. 20-224198 has been developed, such a luminous soccer ball also applied a self-luminous luminous (phosphorescent or phosphorescent) material to the outer surface of the soccer ball and formed a high-density coating layer to form a soccer ball in a dark environment. This makes it easy to identify.

However, the balls of the above type is to apply or coat the luminous light of luminous or fluorescent material on the outer circumferential surface of the ball, so when playing sports with these balls, the fluorescent material is easily peeled off or damaged during the sports game, and thus the desired luminous effect The fluorescent material applied on the outer circumferential surface of the ball was significantly lower in luminescence with time, so the more the ball was used, the lower the luminescence of the fluorescent material. It is difficult to play the ball at night or at night when it can not be, and has a problem in the service life as a luminescent ball that emits light at night.

The present invention has been developed to solve the above problems, the method of manufacturing the retroreflective ball and the retroreflective ball of the present invention, the outer surface of the ball and the retroreflective park step produced by the manufacturing method of the present invention in any shape and It cuts in shape, and the edges of the cut pieces of the retroreflective ball fabric are processed at high frequency, and then bonded and sewn to the outer tube of the tube or the inner layer of the ball, so that the position of the ball even when the retroreflective ball receives only a little light at night It is very suitable for night games, and it is possible to prevent traffic accidents when returning home or moving at night by a retroreflective ball, and even if the retroreflective ball falls to a dark place during the night game. It is very easy to see the location of.

The retroreflective ball of the present invention can be applied to various sports balls such as soccer ball, basketball ball, volleyball ball, handball ball, rugby ball and dodge ball, even if the retroreflective ball is continuously used during these sports. The luminescence of the ball is not reduced, or the outer circumferential surface of the retroreflective ball is not peeled or damaged.
