To understand this problem, we can start with understanding the structure of basketball. The structure of basketball includes lining, winding, middle lining, outer skin and ball mouth from the inside out. We see that the color difference of basketball is the color of skin.
1, liner: that is, the bladder, that is, the heart of basketball, is made of black rubber at the innermost layer of basketball;
2. Wire winding: Nylon wire special for basketball must be evenly wound on the inner lining surface of the ball to form a cocoon-like protective layer for the bladder. However, not every kind of basketball adopts this technology. Many low-grade basketballs do not wrap silk, but use gauze instead.
3. Intermediate bladder: the supporting structure between the inner bladder and the epidermis is made of rubber;
4. Skin: divided into three categories: rubber, synthetic leather (superfine strong fiber, PU, PVC, etc. ) and dermis;
5, the ball mouth: the "throat" of basketball inflation is very important for air tightness.
