RETROREFLECTIVE ARTCLES IN THE FORM OF GARMENTS, FIBERS AND FILAMENTS

摘要

Retroreflective articles are provided in the form of garments, fibers and filaments made with retroreflective elements that each include a solid spherical core (110) with an outer core surface, the outer core surface (115). providing a first interface; a first complete concentric optical interference layer (120) having an inner surface overlying the outer core surface (115) and an outer surface (125), the outer surface of the first complete concentric optical interference layer providing a second interface. In some embodiments, the retroreflective elements each include a second complete concentric optical interference layer having an inner surface overlying the outer surface of the first complete concentric optical interference layer and an outer surface, the outer surface of the second complete concentric optical interference layer providing a third interface. In other embodiments, the retroreflective elements each further include a third complete concentric optical interference layer having an inner surface overlying the outer surface of the second complete concentric optical interference layer and an outer surface, the outer surface of the third complete concentric optical interference layer providing a fourth interface. The garments include a surface having a plurality of the foregoing retroreflective elements disposed on the surface. The fibers include an elongate fibrous body having a plurality of the retroreflective elements adhered to the fibrous body. The retroreflective filaments each include a hollow, transparent, tubular member having a plurality of the retroreflective elements contained within the tubular member.
