It is not difficult to find such two groups of people: traffic police and sanitation workers, whether on the crowded urban roads or on the flowing highways. Most of their duty hours are outdoors, no matter during the day or at night, so they wear reflective vests, also known as traffic vests or sanitation vests. As the name implies, reflective vest refers to the protective vest that is often worn by outdoor duty departments such as traffic management, environmental sanitation and road administration to play a reflective protection function. Its design and production standards fall within the scope of the national standard GB20653.

Although the traffic control and sanitation crowd and reflective vests have become commonplace for us, it is unlikely that many people can tell us what design requirements are for reflective vests worn by traffic police and sanitation workers. For example, do you know the width of reflective vests and reflective belts worn by traffic police? I believe not many people can answer.

Material area
According to the provisions of the national standard GB20653, warning clothing such as reflective vests should be divided into three levels, and the material area of each level (unit: square meters) is also divided from two aspects: the base material (clothing fabric) and reflective material (reflective tape, etc.).

Style design
1. The base material shall surround the torso, sleeves and trouser legs;
2. The width and total area of reflective tape shall meet the requirements;
3. The interval between multiple reflective belts should be placed on the vest and vest, and the tilting angle of each reflective belt should meet the requirements of the national standard;
4. There should be a reflective belt on both shoulders that links the torso from front to back, and the distance from the lower reflective belt of the torso to the bottom edge of the clothes should not be too small or too large;
In addition, problems such as the reflection distance of the reflective belt at night is not enough 330m, and the mesh is black, are also matters that should be paid attention to in the design and production process of the reflective vest/vest.
Speaking of this, I believe you have a new understanding of reflective vests and sanitation vests. However, not all manufacturers and brands are designed and produced in strict accordance with the national standard. Therefore, although some reflective vests look gorgeous, the reflective warning level cannot meet the standard because the quality, area and sewing requirements of the base material and reflective material are not up to standard.
