With the development of social life and traffic, people pay more and more attention to their own traffic safety, and the use of reflective materials has become more and more extensive. In the day with its bright colors play an obvious warning role, in the night or in the case of insufficient light, its bright reflective effect can effectively enhance people's recognition ability, see the target clearly, cause alertness, so as to avoid accidents, reduce casualties, reduce economic losses, become an indispensable safety guard of road traffic, with obvious social benefits.

Retroreflective fabric is commonly known as reflective cloth. It is the optical principle that glass beads are applied to the fabric and the light is refracted and reflected in the glass beads. Even if the reflected light mostly returns to the light source direction in the direction of incident light. This kind of fabric is a kind of fabric with safety function. When the personnel at night or in the dark place wear or carry this kind of safety material of regression reflection, in case of light irradiation, due to its function of regression reflection, it will produce eye-catching effect and improve their visibility, so that the personnel at the light source can quickly find the target, effectively avoid the occurrence of accidents and ensure personal safety.

The reflective fabric is composed of directional reflective main body glass beads, reflecting mirror layer, fabric substrate, adhesive, etc. when the light rays irradiate the glass sphere, the light will refract in the glass medium. After being reflected by the specular layer on the back surface of the sphere, it will return to the light source direction through the spherical refraction. Thus, the purpose of returning the reflected ray direction according to the incident direction is achieved. There are three manufacturing methods of reflective cloth: coating bead method, planting bead method and transferring method. Different methods have different processing routes and different chemical raw materials, and the reflective strength, hand feel and performance effect of the reflective cloth are different in different degrees. As the safety functional reflective cloth used in clothing, in addition to high reflective strength, it must also ensure the wearing requirements, such as washing resistance, wear resistance, waterproof, etc.
