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.

Abstract: A sports ball includes an inflatable ball or a non-inflatable ball. A photosensitive layer is provided on an outer side of the non-inflatable ball. The inflatable ball includes an inner bladder. An outer side of the inner bladder is bonded to a patch layer through an adhesive layer. A valve core is fixed and penetrates from an inner side of the inner bladder to an outer side of the patch layer, such that the inner side of the inner bladder communicates with the outer side of the patch layer through the valve core. A spacer groove is formed between the outer side of the inner bladder and the patch layer. A sealing strip is bonded to an inner side of the spacer groove; and the photosensitive layer is provided on the outer side of the patch layer. The photosensitive layer includes UV photochromic powder.
