The bast fibers of paper mulberry were dyed by using sappan wood, gardenia, and gallnut extracted under various extraction conditions. The surface absorption rates, color, and sunlight fastness of the dyed fibers were compared to those of the dyed cotton and silk. The K/S values of silk showed the highest values, followed by gallnut, gardenia, and sappan wood. The optimum extraction conditions of the dye materials were 20 g/L (input amount of dye materials per liter), $90^{\circ}C$ (extraction temperature), and 30 minutes (extraction time). The values of saturation were observed to increase with the increase of the amount of dye materials, extraction time, and extration temperature. However, no effect were found on the values of hue and lightness. In all samples, the developed colors dyed by sappan wood and gardenia were the series of YR, and Y, respectively. The colors of dyed cotton and bast fibers of paper mulberry by gallnut were the series of Y and the dyed silk showed the series of YR. The values of saturation of the bast fibers of paper mulberry by sappan wood and gardenia showed the highest values of saturation, followed by cotton, and silk. In the case of gallnut, cotton showed the highest values of saturation, followed by the bast fibers of paper mulberry, and silk. The sunlight fastness were not improved in all dyeing conditions.

The purpose of this study was to investigate the functional properties of Changhoji with natural dyeing. This research would provide a basic information for interior material Changhoji. To estimate functional properties of super eight colors Changhoji, water staining, lightfastness, and floodlight color test were executed. In term of the water staining test, blue color showed the clear and other colors showed the little spot. As a result of measuring the lightfastness, Magenta color dyed with sappanwood showed the worst. But blue color dyed with indigo and Turquoise color dyed with indigo and Pagoda tree flower showed the highest. As a result of floodlight color test was no difference between sample color and floodlight color.

The traditional Korean hand-made papers (Hanji) were dyed with colorant extracted from flowers of Sophora japonica L.(pagoda tree), and the effect of various dyeing factors (mordant, mordanting method, pH of dyeing solution, etc.) on colors and K/S values of the dyed Hanji was investigated. Changing mordant affected the color of dyed Hanji. Mordanting with alum, copper acetate made the color of dyed Hanji more yellow, but dyed Hanji mordanted with $FeCl_2$ had dark olive color. The K/S value of the dyed Hanji mainly depended on the pH of the dyeing solution and mordanting method. It was found that sim-mordanting with alum was timesaving and effective dyeing method. The dyed Hanji sim-mordanted with alum had the highest K/S value at low pH (about 4).

국립 중앙 박물관의 소장품은 다양한 재질로 구성되는데, 그 중 목재, 종이, 피혁 등 유기질로 이루어진 것들은 충균의 피해에도 민감하여 훈증에 의한 관리와 방충·방균제가 병용되고 있다. 본 실험에서는 박물관에서 사용되는 각종 재료들의 유해성을 판정하는 Oddy test를 응용하여 방충·방균제가 염색지의 색변화에 미치는 영향을 검토하였다. 그 결과 B사 H제품이 염색지의 색변화에 가장 영향을 적게 미치는 것으로 관찰되었다. 코치닐과 울금 염색지의 실험 결과에서 염색지와 함께 노출된 시편과 비교하여 대조군의 변화가 매우 크게 나타났다. 이는 시료보다 습도에 의한 영향이 크기 때문으로 생각된다.

Recently increasing eco-efficiency of natural dyeing has become an important topic. The purpose of this study was to manufacture colored pulp for interior materials by combining color therapy and natural dyeing. For this purpose, through experiments with water-bleed, K/S value and chroma changes of samples in pulp for interior materials.

In previous paper, the optical behavior of coloring matter of Cromwell under several conditions were investigated. In this paper, the fading behavior of color solution extracted from Growell by methanol, dyeing properties of this color on the silk fibers in water and methanol, the three property of color of dyed silk fabrics, and fading behavior of dyed silk fabrics with Cromwell color under light and washing were discussed.

Inlay is a high technique of inlaying patterns on the surface of crafts and widely used transcending time and place at various hand crafting area. Inscribed pattern technique using rare materials in the area have been used by the artisans of artistic flair and functionality and its value is also highly regarded from ancient to modern and inherits and is being developed today. Existing inlay technique, however, has not been spread out because it needs craftsman's skill based on the handcraft and inscribed materials are very rare to use. This paper aims to replace natural wood Sanggam materials for traditional furniture patterns such as Samho Jang, Ohho Jang, Seongtoenoe Moon, Gyeopgwinoe Moon and wood inlay text like Soo (Long life), Bok (Luck), Kang (Peace), Ryoung (Relaxed) and gammadion cross pattern. Gathered black, yellow and white color dyed wood using power tools can replace rare natural inlay materials through reliable and standardized supply. Dyed-gathered inlay materials can easily replace wood inlay materials, therefore, attempt to create an improved direction regarding materials and fabrication techniques in order to make traditional or contemporary artistic furniture to be produced.

This paper aims to compare and verify the antibacterial effects of cotton fabrics naturally dyed with extracts of Ulmus davidiana var. japonica Nakai, Caesalpinia sappan, Saururus chinensis, and Artemisia princeps against antibiotic-resistant strains of bacteria. After natural dyeing of the test fabric, Al, Cu, Fe mordants were used. The color fastness against washing, rubbing, and perspiration of the cotton fabrics dyed with the 4 types of extracts were mostly excellent. However, the color fastness against light showed poor results for all four types. As for the antibacterial test method, MRSA (ATCC 33591) was applied to the cotton fabrics dyed with the four kinds of extracts and cultured for 24 hours. After that, the bacteria that proliferated on the fabrics were collected and spread on a solid medium. The bacteria were measured to find out the bacteriostatic reduction rate for the antibiotic-resistant strains. As a result of the analysis, all four extracts showed a high bacteriostatic reduction rate of more than 99% when the copper mordant was used. Even with the lack of a mordant, the bacteriostatic reduction rate was high, at 99.9% for Caesalpinia sappan and 94.6% for Saururus chinensis.

The objective of this study was to find in what color Hanji(Korean hand-made paper) is dyed when it is dyed with a pigment extracted from clove tree using different kinds of mordant, and how the paper is discolored and variety of strength under the condition of accelerated aging test. The results of this experiment are as follows. The Hanji dyed with aluminum acetate mordant was colored yellowish brown at pH 4.82, discoloration after aging was as much as a slight difference of color was recognized, and the decrease of strength after aging test was small. Thus, the method using aluminum acetate mordant was usable in coloring Hanji. The second most useful Hanji dyeing moth of was using distilled water and ferrous sulfate mordant, which dyed Hanji light brown at pH 6.03. However, when pigment was extracted using distilled water and copper sulfate mordant was used, discoloration was satisfactory but strength decreased too much and pale brown was obtained. Thus, this method was not usable.
