Abstract
A luminous leather for a sports ball includes a base fabric, a polyurethane (PU) layer, a luminous layer and a film. The base fabric, the PU layer, the luminous layer and the film are sequentially bonded by glue from bottom to top. The luminous layer is a fluorescent coating. The luminous leather for the sports ball has an enhanced luminous effect while being wear-resistant. In the new luminous leather, the luminous layer is added, and the luminous layer is a fluorescent coating. In this way, sports balls made of the new luminous leather come in different surface colors to be more entertaining. Meanwhile, a film is immediately coated onto the luminous layer by a roller before the glue gets dry to enhance the luminous effect and the color brightness, while making the entire leather more wear-resistant.
