  The present invention relates to a monoazo-based dye for acid detection, which changes color upon addition of or exposure to acid and, more specifically, to a dye which changes color within a few seconds upon exposure to a trace amount of a strong acidic material, and a fiber product using the same. The monoazo-based dye for acid detection according to the present invention has an effect of reacting with a trace amount of strong acid to change color, and returning to the original color when the acid is removed. Also, a fiber dyed with the dye of the present invention exhibits high color fastness and thus is not discolored and faded by laundering or sunlight. In addition, there is an effect of preventing secondary contamination at an accident scene and serious accidents from harmful environmental factors, when protective or working clothes are manufactured applying the effect, thereby providing a function enabling workers to recognize an exposure to acid in real time in the case of an exposure to an acid-contaminated environment.

  本发明涉及一种用于酸检测的单偶氮基染料，这种染料在加入酸或接触酸后会变色，更具体地说，涉及一种在接触微量强酸性物质后几秒钟内就会变色的染料，以及使用这种染料的纤维制品。根据本发明，用于酸检测的单偶氮基染料具有与痕量强酸反应变色的效果，并且在除去酸后恢复原色。此外，用本发明染料染色的纤维具有很高的色牢度，因此不会因洗涤或日晒而变色和褪色。此外，应用本发明制造的防护服或工作服还具有防止事故现场二次污染和防止有害环境因素造成严重事故的效果，从而提供了一种功能，使工人在接触酸污染环境时能够实时识别是否接触酸。

  본 발명은 산 첨가 또는 노출시 색상이 변화하는 산 감지용 모노아조계 염료에 관한 것으로, 더욱 상세하게는 극미량의 강산 물질에 노출되면 색상이 수초 내로 변화하는 염료와 이를 적용한 섬유제품에 관한 것이다. 본 발명의 산 감지용 모노아조계 염료는 극미량의 강산에 반응하여 색상이 변화하며 다시 산 제거시 원래의 색으로 돌아가는 효과가 있다. 또한, 본 발명의 염료로 염색한 섬유는 높은 견뢰도를 나타내어 세탁이나 일광에 의한 변색 및 퇴색이 없고 이를 적용하여 방호복 또는 작업복을 제조시 산 오염 환경에 노출될 경우 작업자로 하여금 실시간으로 산 노출 여부를 인지하게 하는 기능을 제공함으로써 사고 현장에서의 2차 오염 및 유해환경 인자로부터 대형 사고를 예방할 수 있는 효과가 있다.
