초 록
포름알데히드는 전시․수장 공간에서 농도와 발생빈도가 높아 전통직물(천연염색)에 대한 손상 개연성이 있다. 본 연구는 견, 면, 모시, 삼베의 무염색, 천연염색(적색, 황색, 청색, 흑색) 시편을 대상으로 포름알데히드 0.5, 1, 10, 100, 500 ppm 농도에서의 손상, 손상농도 500 ppm에서 온습도 조건에 따른 손상과 열화상태에서의 손상을 광학적, 화학적, 물리적 측정방법으로 평가하였다. 이 결과, 포름알데히드 농도 500 ppm에서 일부 직물의 색차, 변퇴색등급, 포름산이온 농도, pH가 변화하였으며, 고온․고습조건(30℃, 80%), 고습조건(25℃, 80%)에서는 색차, 변퇴색등급, 포름산이온 농도가 2배 가중되었다. 그러나, 열화직물은 열화정도, 열화 생성물질로 인해 포름알데히드에 의한 손상변화가 미미하였다. 이를 통해 포름알데히드에 의한 전통직물의 손상, 손상농도, 손상가중 조건, 열화상태에서의 손상을 확인하였으며, 포름알데히드는 적색직물의 황변, 열화직물의 황변 탈색, 포름산은 전체직물의 탈색에 영향을 미치는 것으로 나타났다.

Formaldehyde(HCHO) may have a damage effect on Korean traditional textiles, because concentration is high and occurrence frequency is frequent at the exhibition room and storage area. Total 20 specimens were prepared using 4 different materials (silk, cotton, ramie, hemp) after dyeing with 5 colors (undyed, red, yellow, blue, black). The specimens were exposed to HCHO gas in the test chamber. The gas acceleration test was conducted to identify the deterioration of Korean traditional textiles according to HCHO concentration(0.5, 1, 10, 100, 500 ppm), to temperature-humidity condition at HCHO 500 ppm, and deterioration conditions at HCHO 500 ppm. Optical, chemical, and physical evaluation was carried out after the exposure. The results, color difference, grey scale rating, formate(HCO2-) of some textiles increased at 500 ppm, while pH decreased at 500 ppm. Also, color difference, grey scale rating, formate(HCO2-) of some textiles increased double damage at high temperatures & humidity, high humidity condition. But, damages of accelerated degradation textiles were slight, because of degradation degree and degradation products. The results suggest that determined the damage to the korean traditional textile, damage level, damage-weighted condition, damage to accelerated degradation textiles. In addition, formaldehyde damaged to yellowing of red textiles, bleaching of accelerated degradation textiles, formic acid damaged to bleaching of total 20 specimens.
