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.
