Ball sports are used for various purposes among athletes. Volleyball is one of the most popular sports which very limited during the outbreak of Corona virus. Therefore, the purpose of this study was to design a new anti microb and virus Volleyball ball. The present study was done in order to design and manufacture new Volleyball ball to prevent microbes and virus distribution among Volleyball athletes. Initially, in order to design and produce a new antimicrobial Volleyball ball to prevent germs and viruses among Volleyball athletes, using rubber, it was combined with the material of sports balls such as titanium oxide, paraffin, and etc in the Nider machine. The obtained rubber material was transferred to the rubber baking machine for making the first layer of the ball. Then, in order to maintain the spherical shape of the first layer of the new Volleyball ball, we covered it with thread. To form the third layer of the new ball and to increase its bounce, a special fabric was used instead of rubber. Finally, we used special leather foam to form the last layer of the new ball. In the latex machine, we covered it twice with glue in order to better adhesion of the foam to the third layer. For the first time in the ball industry, this study investigated the antimicrobial ability of nano-silver against microorganisms .Based on previous research that examined the antimicrobial properties of nano-silver against microbes in various industries , it can be suggested that the use of nano-silver in the ball industry could be useful in eradicating a variety of microbes and viruses.
