Abstract: In a process for manufacturing to a 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, the ultraviolet-fluorescent yarns are arranged repeatedly in specific color order in the traverse direction during the warping operation. In the process, these yarns as the warp are also woven into a double-wide textile with a wide loom.

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.

Abstract: A woven tape or label having fiber molten parts generated on both side edges thereof is provided with a tape body and two lines of chain stitch, each line of the chain stitch having a large number of loops formed with one sewing thread, and thus each of the fiber molten parts is wrapped in the chain stitch of one sewing thread. The chain stitch prevents the fiber molten parts from projecting when the tape or label is bent and sewn on an article of clothing. If desired, the label can contain shrinkable yarns interwoven partially as weft yarns in portion thereof applicable as one or two bent places at sewing.

Abstract: A woven security label is woven from threads of synthetic fiber, which interweaves a piece of check warp or weft yarn. The check warp or weft yarn comprises one or more pieces of detectable filament containing a small amount of inorganic fluorescent substance. The check warp or weft yarn is substantially colorless in ordinary sunlight, electric light or the like but reversibly changes color under influence of specific UV light.
