Which threads appear to glow under a black light?

Many longarm machines are compatible with black light LEDs that can be plugged into the lighting panel. Quilting under black light can help you see fluorescent threads better, as they appear to have a glowing effect when exposed to UV light. What makes some threads glow under a black light?

It's time for Superior's unofficial chemistry 101 lesson - A black light (bulb, LED, or tube) gives off ultraviolet light which happens to be highly energetic. The human eye can't see this light of the spectrum (perhaps this is why it became known as black light?). Fluorescent substances absorb the ultraviolet light, then re-emit it almost instantaneously. Threads which are dyed with fluorescent pigments or threads which are bright white will absorb the black light and reflect it back with a wonderful, glowing sheen.
