he accidents caused by hazardous chemicals have potential dangers
everywhere in the industry. Occasionally, chemical-related accidents lead
to fire and explosion, which damage not only environment but also human
life seriously. Especially, accidents caused by gaseous chemicals are highly
dangerous due to high spread rate and invisibility of the gas. Therefore, it is
important to prevent chemical accidents in advance by detecting and treating
them early in the accident. In this research, to detect harmful strong alkali
gas immediately with naked eyes, we synthesized pH sensitive dimethine
dye and fabricated textile sensors by incorporating the dye into textiles.
The nylon6 and polyester fabrics were selected to apply dyeing and printing
method respectively, and the sensitivity to alkaline gas was tested with 400
ppm of ammonia gas. Both of the dyed or printed fabrics showed definite and
reversible colour change when the alkaline gas was injected directly. From the
results, it should be promising candidate as a colorimetric textile sensor for
alkaline gas detection.
