  • Due to the complex environment in the ground, most of excavated costumes undergo deterioration and color change. To reduce the extent and intensity of the staining and to recover the original color or gray fabrics of excavated costumes, bleaching would be required. Excavated historical costumes are very delicate in nature, therefore, special care is needed in bleaching process. Several bleaching agents were selected and applied to the control cotton fabric and pre-deteriorated cotton fabrics to examine the change of color and physical properties after bleaching. A dual bleaching using hydrogen peroxide and sodiumborohydride showed the superior bleaching effect to the other bleaching agents. The strength of pre-deteriorated fabrics slightly increased after dual bleaching. The six historical costumes which belonged to General Duk-Ryung Kim's nephew's wife were dual bleached. They became remarkably cleaned and brightened. The treatments improved the appearance of costumes. By microscopic investigation, it is found that costumes did not show the damage after treatment. In conclusion, it is possible to bleach historical textiles without damage using appropriate bleaching agents like hydrogen peroxide and sodiumborohydride.

  • This study was aimed to decrease AOX(Adsorbed Organic Halide Compounds) by applying bleaching methods of A(HNO$_3$ + NaNO$_2$) and $D^{(H/L)}$(dual pH chlorine dioxide bleaching) to conventional OCEDED bleaching stages. And so we investigate the effects of NSA treatment and the influence of production rate of ion species in chlorine dioxide and pulp mixtures according to various pH as well as dual pH on pulp bleaching. Finally the effects of AOC_DED^{(H/L)}ED^{(H/L)}$ bleaching stage were investigated by measuring AOX, brightness, kappa number and viscosity of pulps. A stage was treated by using 4% $HNO_3$ and 0.05~2.0% $NaNO_2$ on pulp and $D^{(H/L)}$ stage was like that pulp mixed with chlorine dioxide solution was adjusted at pH 7.0 and reacted in pulp cosistency 3%, S~20min, $70^{\circ}C$, and then successively for 160~175min at pH 4.0. It was found that suitable $NaNO_2$ addition rate was at 0.6% where the brigtness of pulp was most higher and pulp viscosity was not decreased much. Chlorate ($CIO_3$) was decreased according to pH increase but chlorite($CIO_2$) was highly decreased according to pH increase. And chloride was slightly increased with pH increase. The applying of A and D^{(H/L)}$ bleaching stages to some various multiple bleaching stages ($AOC_DED^{(H/L)}/EopD^{(H/L)} etc.$) had good results that brightness was increased more 2~3% ISO than conventional method(OCEDEopD), but viscosity was dropped by only 1~2cps.

  • The most ideal textile conservation is to block oxygen and light from historical textiles. However it is not possible because historical textiles should be examined, cleaned, restored, and exhibited to find out its historical value. Most of excavated costumes were severely stained and soiled. They are dark yellowish brown in color. To reduce the extent and intensity of the staining and to recover the original color of gray fabrics, bleaching would be required. Conservation treatment was carried out on the 8 historical costumes which belonged to General Duk-Ryung Kim(1567-1596). Two of them do not hold the fabrics. They hold only cotton wool and a little piece of fabrics. Even though these costumes underwent the conservation treatment in 1979, they were stained and needed re-treatment. This time, they were dual-bleached using hydrogen peroxide and sodiumborohydride followed by wet cleaning to reduce the soils and stains. The treatments improved the appearance of costumes. Through the analysis of the trace of fabric, carbonized fabric fragment, and fabrics remained in other garments, we concluded the missing fabrics to be ramie or cotton. It is different result from the primary report concluded to be silk.

  • 중세 기독교 회화에서 그리스도를 표현하는데 있어 가장 중요시한 문제는 그의 신성과 인성을 동시에 나타내는 것이다. '그리스도의 변형' 도상은 다른 어떤 주제보다 그리스도의 두 가지 속성을 뚜렷하게 보여준다. 본 연구의 목적은 예형론과 기독론을 통해 중세 그리스도 변형 도상의 신체와 복식에 나타난 그리스도의 신성과 인성의 표현을 고찰하는 것이다. 이를 위해 그리스도의 두상표현과 자세, 복식의 종류와 색상, 형태, 재질 및 장식, 조형성을 살펴보았다. 연구 결과 신성은 푸르거나 어두운 색조의 얼굴과 삼위일체와 강복을 상징하는 오른손, 오란스, 공중부양 자세로 나타났고, 인성은 홍조가 도는 따뜻한 색감의 피부를 지닌 장년 남성의 얼굴과 콘트라포스토 자세로 나타났다. 복식에서 흰색, 푸른색, 보라색, 금색 및 탈색효과는 신성을, 붉은색 및 고채도의 색상대비는 인성을 강조하기 위한 표현으로 분석되었다. 또한 비구조적인 주름과 직선적인 드레이퍼리, 목둘레의 장식선 등은 신성의 특징으로, 구조적이며 사실적인 주름의 묘사는 인성의 표현으로 나타났다. 중세 그리스도 도상은 인간의 모습으로 이 땅에 내려온 신의 형상을 구현하기 위해 철저히 계획된 의도의 산물이다. 이는 화가 자신의 신앙의 고백이자 중세 신학의 도그마를 전달하는 수단으로서 중요한 의의가 있으며 추상적인 개념을 시각화하여 전달하는 이미지의 중요성을 시사한다.
