The reflective materials used by manufacturers of reflective vests are generally composed of a base fabric, an adhesive, a fixed layer of glass beads, and glass beads.
The principle of reflective materials is based on the principle of retroreflective reflection of a sphere formed by high-refractive glass beads, or the principle of retroreflective cube corners formed by a microcrystalline lattice composed of transparent resin, which can reflect light back to its light source and produce a good Reflective effect and warning effect, especially at night, it can have good retroreflective optical performance, so that the wearer has high visibility. When you buy a reflective vest, you will find that there are countless densely packed small particles on the reflective tape. If you scrape it hard with your nails, it will fall off.
When buying a reflective vest, pay attention to check whether the reflective distance is up to the standard. The reflective distance of the high-visibility warning suit is not less than 300m.
Reflective vests actually refer to the protective vests often worn by outdoor duty departments, such as traffic management, sanitation and road management, to perform reflective protection functions.
When designing a reflective vest, the base material should surround the torso, sleeves and trouser legs; the width and total area of the reflective belts should meet the requirements; the vest and the vest should have the interval between multiple reflective belts, and the maximum tilt of each reflective belt The angle should meet the requirements; there should be a reflective belt on each shoulder, connecting the reflective belt of the torso from front to back, and the distance between the reflective belt under the torso and the bottom of the clothes should not be too small or too large.
Attention should also be paid to the problems of insufficient reflection distance of the reflective belt at night, such as 330m, and black mesh cloth, which should also be paid attention to in the process of designing and making reflective vests.
