The body of reflective vest consists of fluorescent fabric and reflective material. The color of fluorescent fabric is eye-catching and colorful. The common colors are fluorescent yellow and fluorescent red, and the less common colors are bright red, lake blue, treasure blue, apple green, pink, etc. these colorful colors are gradually applied to reflective vest and are accepted and loved by everyone. Therefore, whether in the daytime or at night with weak vision, the probability of wearing reflective clothing is greatly increased. Reflective vest is mainly suitable for police, road workers, traffic controllers, highway maintenance personnel, motorcycle enthusiasts, construction workers, and other professional workers who need to work at night. It increases visibility in poor environment and avoids the occurrence of danger.

       The reflective materials are generally composed of reflective strips or reflective lattices. The principle of directional return of incident light along the original path is made of glass beads or prism materials. The principle of spherical regression reflection formed by high refractive index glass beads or cubic angle regression reflection formed by microcrystalline lattice composed of transparent resin can reflect light back to its light source and produce good reflection The light effect can make the wearer form a strong contrast with the surrounding environment no matter in the day or night, under the illumination of the light. It is found by the driver within the visual distance of 300m, so as to play a protective role.
