There are utilized at least two kinds of ultraviolet-fluorescent yarns with different chromophore, which is spun out of dope kneaded with a fluorescent material. When ultraviolet-fluorescent yarns and colorless yarns are wound around a beam or drum with or without infrared-fluorescent yarns, ultraviolet-fluorescent yarns are arranged repeatedly in specific color order in the traverse direction during the warping operation. These yarns as the warp are woven into a wide textile with a wide loom. In this weaving, ultraviolet- and infrared-yarns are interwoven in specific color order in parallel with each other over the entire width of the wide textile, which is cut into tapes with heating in the broader width than a space where the color order may be identified.
