Reflective materials, also known as retroreflective materials and retroreflective materials, are widely used in various road traffic safety facilities such as traffic signs, prominent road signs, outline signs, traffic cones, anti-collision pipes, and car number plates, clothing, shoes and hats, fire protection, railways, water transportation, mining areas, etc. , and can be divided into traffic sign reflective materials, road marking reflective materials, protruding road signs, delineator, clothing reflective materials, etc.
The retroreflection function of light is realized by various reflective materials with retroreflection performance. Most of these materials are not naturally formed in nature, but rely on human creativity to invent and synthesize new substances. Retroreflective technology combines optics, materials science, mathematics, organic chemistry and other disciplines and technologies.

With the development of modern road traffic, more and more people perform tasks and operations on the road. In addition, with the acceleration of urban development, the gap between urban and rural areas is getting smaller and smaller, and more and more people will go out to exercise at night and engage in various social activities in outdoor, urban streets, squares and other public places.
In this context, it is necessary to attach a material to the clothes of people who are engaged in road construction or other activities on the road at night, so that the clothes can reflect light under the illumination of light, so as to remind motor vehicle drivers to clearly notice that "someone is on the road" and ensure the traffic safety of pedestrians on the road.
In Europe, there is a famous VIV legislation. The so-called VIV is the abbreviation of Vest In Vehicle, which means that every motor vehicle must have a reflective vest to ensure that drivers can wear reflective vests when they get off the bus for some reason, so as to protect themselves and reduce the probability of accidents.
Reflective materials for clothing were first used in the professional clothing of some road traffic management and service personnel. Such as: traffic controllers, traffic assistants, sanitation personnel, road builders, etc.
Work clothes with reflective performance are usually made of reflective materials by sewing some clothes outside some parts of the profession, or you can make a vest with reflective performance to cover the coat separately. This kind of reflective clothing made of reflective materials is called high visibility warning clothing. High visibility warning clothing has become a special occupational protective clothing for road traffic management and service personnel.
