Reflective vests are clothing with reflective strips made of reflective materials. The types include reflective vests, reflective one-piece overalls, reflective vests, etc. When designing various reflective vests, they are required to have certain basic features.
The reflective part of the reflective vest is made by using the micro-rhombic crystal lattice to produce refraction and high refractive index glass beads retro-reflective principle, and is made by advanced technology of post-focusing treatment. It can reflect the distant direct light back to the luminous place, and has good retroreflective optical performance no matter in day or night. Especially at night, it can exert the same high visibility as during the day.
Safety clothing made of this kind of high-visibility reflective material can be easily spotted by night drivers no matter whether the wearer is in a remote place or under the interference of light or scattered light. The emergence of reflective materials successfully solved the night driving problem of "seeing" and "being seen".
There are 3 types of reflective materials used in reflective vests/vests, namely:
1) Substrate material: Refers to colored fluorescent materials with high visibility, but not required to meet the requirements for retroreflectivity;
2) Retroreflective material: refers to a material with retroreflective properties, but does not require to meet the requirements for the base material;
3) Dual-performance materials: refers to materials with both substrate and retroreflective properties.
Reflective vests/vests are usually used for traffic police, sanitation workers, traffic commanders, and some road maintenance personnel, etc. It is mainly for staff who need to use light as a warning in dark light. The life jackets, lifebuoys, etc. we see all have reflective effects, in order to serve as safety warnings.
