Basketball generally consists of four parts: the inner and outer parts are the inner liner, the wrapped yarn, the middle tire, and the epidermis
1. The inner liner is a balloon, made of black rubber in the innermost layer of the ball.
2. Wrapping yarn means wrapping a layer evenly on the inner surface like wrapping yarn, ensuring the durability and integrity of the ball. Wrap a layer of basketball specific nylon silk around the middle, while low-end basketball is replaced with gauze.
3. Made of medium tire rubber, the supporting structure between the inner liner and the epidermis.
4. The epidermis is divided into three categories: rubber, synthetic leather (strong fibers, PU, PVC, etc.), and genuine leather.
