he growth of chemical industries has increased probability of accidents
related to dangerous chemicals. Various chemicals produced in chemical
industries, such as hydrochloric acid, hydrofluoric acid and methyl isocyanate
are extremely toxic, causing severe damage to human body. In particular,
gaseous chemicals are more dangerous due to their high diffusion rate and
colourless spread. Therefore, it is necessary to detect and visualize gaseous
chemical leaks quickly so that workers can easily recognize it. In this study,
to detect hazardous gaseous strong acids immediately with naked eyes, we
synthesized halochromic rhodamine dye and fabricated colorimetric textile
sensors by incorporating the dye into textiles. The rhodamine dye was applied
to nylon6 and polyester fabrics in the way of dyeing and printing and the acidic
gas sensitivity of textile sensors were tested with 300 ppmof hydrochloric acid.
Both of the dyed or printed fabrics showed fast and reversible color change
under acidic condition. From these results, the fabricated textile sensor can
be promising candidate as a strong acid gas detector useful for a wide range
of application.
