The influence on the discoloration of two dyed clothes by nitrogen dioxide was measured. The apparatus of constant nitrogen dioxide generation was made in order to see the influence of nitrogen dioxide on the discoloration of dyed cloth. The nitrogen dioxide concentration is measured by NO_2 auto analyser. The dyed cloth is exposed to the nitrogen dioxide for a certain time in reaction chamber. For the detection of what extent the discoloration is occurred, the spectroreflectance (400-800nm) was used. In the dry air, the remarkable color fading and change of the materials did not happen. In the wet air (relative humidity 60%), the color of the silk cloth dyed with Acid blue 127 was only faded slightly and the color of the acetate rayon cloth dyed with Diacelliton fast brilliant blue B was faded and changed markedly.
