What is reflective fabric?

Reflective cloth is an exposed reflective material, which is composed of base cloth, glue and high-refractive glass beads. The glass beads are located on the outermost surface of the reflective cloth and are in direct contact with the air. Using the optical principle that the light is refracted and reflected in the glass microbeads and then returned, the reflected light can be reflected back to the light source according to the original path, so that the observer near the light source can clearly see the reflection effect. We often see reflective cloth on the clothing of outdoor workers, which is to use the retro-reflection principle of reflective cloth to improve the visibility of the wearer and ensure personal safety at night or in an environment with weak line of sight.
