Reflective edge strip reflective mechanism

Reflective edge strip is no stranger to everyone. It can be seen everywhere in daily life and production, such as reflective vest, reflective raincoat, various reflective stickers, etc. The main function of reflective edge strip is to reflect the light path to the light source. One of the most important components is reflective glass bead.

Glass bead is a kind of silicate material. When d<0.8 mm and the refractive index is between 1.9-2.1, it has the characteristic of retro-reflection, that is, when a beam of light illuminates the surface of the bead at any angle within a certain range, due to the high refraction of the bead, the light is concentrated on the special reflector at the bead's focus, and the reflector reflects the light back in parallel along the direction of the light source. For example, the manufacturing composition of general reflective cloth is the base cloth, adhesive, reflective layer, adhesive and bead layer.

This is the reflective edge strip's reflective mechanism. Is it relatively simple. However, when it comes to finished reflective vests, it is also necessary to take into account the special needs of environmental protection, washability, wear resistance, climate resistance, and other flame retardancy. Therefore, the manufacturing process of reflective edge strip used in different places will also vary.
