[0002] Basketball is a sport that everyone likes. With the gradual improvement of people's living standards, the requirements for the aesthetic expression of the color of the basketball surface are also higher. In addition, the service life of the basketball is also required to be higher. The existing basketball color is too single and lacks interest. Moreover, the service life of the basketball is too short under frequent use. In addition, the trademark pattern logo is easy to wear and lose, which reduces the interest in using the basketball after long-term use. At the same time, in the production process of basketball, the treatment of the basketball surface is too simple, and it is only roughly brushed with glue and polished, and the skin is pasted, which easily causes the risk of degumming and the hidden danger of peeling. Therefore, it is urgent to develop a reflective basketball and its processing technology that can increase the interest in using the basketball, make the trademark pattern and the surface not easy to wear, and reduce the risk of degumming and the hidden danger of peeling.
