For example, Switzerland's kindergartens and primary schools will send out scarves, schoolbags, and caps with reflective marks after freshmen’s registration. Many countries require the elderly and children to go out in bad environment such as rain, fog, snow and night. Must sign with reflective material wear or wear with reflective material logo apparel: China Beijing Working Committee on women and children started the child injury prevention intervention project, one of them wore reflective tape is in the bag, reduce the probability of occurrence of traffic accidents in children. If the project will be extended to all over the world students' clothing, clothing with reflective material to each 0.01M - meter, can foresee the reflective material usage will be considerable.

The famous foreign sports and leisure products companies aim at the outdoor sports lifestyle of urban office workers in the morning and evening. They take the lead in the use of reflective materials in clothing, shoes and caps and bags, and make the costumes on the beautiful and practical basis, and increase the safety function.
For major central cities and tourist cities, setting up good guide signs, new and beautiful street names, fresh tourist attractions signs and bright traffic signs is one of the most effective ways to attract foreign tourists and show their images. These signs not only bring the concept of safety warning to every corner of the city, but also enable the driver to have the correct guidance in the complicated traffic environment, and it will produce good social benefits for effectively displaying the city image and urban management ability.

The planned special market generally refers to the areas where anti light materials must be used in accordance with the state directive and regulations.
At present, all countries in the world have legal provisions, outdoor workers must wear high visibility warning clothes. The United States and European countries pay special attention to high visibility warning clothing. In order to ensure the quality of warning clothing, the European standard EN471 and the American Standard ANSI/ISEAl07 are adopted by countries all over the world. The standard content includes the grade and design of the high visibility warnings, the technical requirements of the fluorescent materials, the technical requirements of the antireflective materials, and the nursing labels. European and American high visibility warning clothing perform the product certification market access system according to the above standards, and even use the warning clothing standard as a basis for insurance compensation after traffic accident.

According to the application field of the reflective material, it can be divided into two types: the planned special market and the civil market.
In addition, the use of highly reflective materials in clothing is also a trend in the fashion of international clothing. It is the embodiment of fashion and high-end features.

Highly reflective materials, also known as a retroreflective material. It includes reflective tape, reflective ink, reflective marking paint, reflective cloth, reflective leather, reflective ribbon and reflective safety silk fabric. The principle is to introduce a high refractive index glass bead or three prism microcrystal lattice structure on the surface of the corresponding material, and return the light to the light source according to the original way, so as to form the phenomenon of regressive reflection. Under the light of light, the reflective material has several hundred times visual effect than other non-reflective materials.
According to the statistics of traffic safety department showed that traffic accident probability at night was significantly higher than that in daytime, the accident peak in this period at 8 ~ 10 points; the relevant probability of road signs and pedestrian accidents and dressed as 70%. Using highly reflective materials set up conspicuity traffic signs, vehicle license, road traffic staff wear high visibility warning, the traffic accident rate decreased by 30% to 40%. The application of reflective materials on traffic signs, signs and marking lines greatly promotes the safety between cars and roads.

According to the size of the inverse reflection coefficient and the stability of the influence on the climate. The reflective material is divided into three class: class 1 for the diamond, retro reflection coefficient is the highest, the strongest weatherability; class 2 high intensive beads, retro reflection coefficient and weatherability slightly worse; class 3 for the engineering grade, retro reflection coefficient and resistance are poor.
On the high visibility warning clothing, road clothing workers, aviation ground crew, firefighters, miners and rescue workers and other professional clothing are high visibility warning clothing. High visibility warning clothing is a fluorescent material base cloth, and silver reflective tape fit or sewn to either day or night (or gray background) in the light irradiation, can highlight the wearer's presence in the vision, as a warning to others, to avoid accidents.
For example, all countries require the use of reflective tape to show the vehicle profile for heavy goods vehicle. USA DOT Reflective Tape Regulations; Europe ECE 104 conspicuity tape requirements;

For example, in many famous international brands such as NIKE, C&D, BDGYGUARD, CAMEL, ADIDAS and REEBOK, we can see the application of reflective heat transfer materials. Highly reflective materials have become a new choice for people to travel safely.
One is an exserted type, which usually uses glass beads as a reflective element. The reflector is located on the surface of the reflective material and directly contacts with the air. The two important parameters of the glass bead, namely, the curvature radius (γ) and the refractive index (n) directly affect the focus of the light, and then influence the effect of the light. In order to achieve high reflectivity, refractive beads generally choose between 1.9 ~ 2.2, 22 ~ 24 between the radius in the range. The other is the flat top type. Generally, the three prism microcrystal lattice structure is used as the reflecting element, and the reflective elements are embedded in the transparent glue. The structure is more complex, and the requirement for the equipment technology is also high. Its advantage is that the structure of the prism microcrystal is relatively regular, and the area of the reflective light is large, so it has a good anti light effect, and it is also the contact between the transparent glue and the air. The surface is not easy to stick to the dust. Good weather resistance, rainy days are not affected.

In recent years, with its unique visual effect, reflective materials have been widely used in various warning signs, lifesaving marks, textile products, advertising and other fields.
The reflective performance of the reflective material is evaluated by the parameter retro reflection coefficient. The retro reflection coefficient is the ratio of the reflection intensity (I) of the material to the product of the vertical incident light (E) and the area of the reflector in the direction of observation. If the retro reflection coefficient is expressed with symbol R ', there is R' =R/A=I/ (E*A)
The civil market of the reflective material will also be gradually expanded with the increase of people's safety awareness
In traffic signs, signs, and marking lines all over the world, all countries in the world have legal provisions, traffic signs, signs, marking and other necessary use of reflective materials.
The civil market generally refers to the fields of all kinds of clothing, clothing, bags, billboards and so on. The use of reflective heat transfer vinyl in clothing, shoes and caps, bags and other products is different from ordinary textile fabrics. It is used in ribbons, characters and decorative patterns. Although it only occupies a small area in the product, the use is far less than the ordinary textile fabric. But it can increase the sight distance of the product at night, and greatly improve the safety factor of the product.
