reflective material has retroreflection function Applying the principal of retroreflection of high reflectivity glass micro beads. We adopt the advanced technology of post treatment of focus control. When light hits glass beads. It is first refracted through the surface, then redirected back toward the light source. producting a brilliant reflectivity effect of high visibility whether day or night,especially at night time. 　　This high visibility allows wearer to be easily detected by moving vehictes at great distance at night in twilight conditions or in cluttered environment. Therefore Yijian brand reflective material produces superior safety as well as extremely identifiable corporate image. 　　 Features： Retroreflective Brightness：reflective material provides maximum brightness for superior visibility. Its silver color series products have the coefficient of retroreflection R?400cd/lx.m2； Brightness Angularity：reflective material remains highly reflective when viewed at wide entrance angles. Wash Durability:Yijian brand reflective material is machine washable or dry cleanable, Over 85% of its original brightness can be retained after repeated washings. Flexibility: reflective material shows nice hand feel and remains flexible after application. Wide versatility:Material applies well to most fabrics for making safety belt/vest, work uniform, rainwear, sports wear, bags, gloves, shoes and articles for use of fashion accessories, etc.
