| 20110135854 | SECURITY TAPE WITH SPECIFIC PATTERN INTERVAL - 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 warp 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 double-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 total width of the double-wide textile, which is cut into tapes with heating in the broader width than a space where the color order may be identified. | 06-09-2011 |
