This study examined the effects of the number of Dakji layer (a layer, two layers), the time of Jumchichigi (20, 40 and 60 minutes) and the type of Choji method making Dakji (Oebal-teugi, Ssangbal-teugi) on five strength properties of Jumchi-Hanji. As a result, the number of Dakji layer and the time of Jumchichigi influenced the five strength properties (tensile, wet tensile, tearing, bursting, and folding strengths). Jumchi-Hanjis made with two layers of Dakijis had higher properties than Jumchi-Hanjis with a layer of Dakji in the strength properties. The more the time for Jumchichigi is spent, the more the five strength properties of Jumchi-Hanji increased. The type of Choji was related to only three strength properties. The tearing strength of Jumchi-Hanjis with one and two layers, and the wet tensile and the folding strengths of Jumchi-Hanjis with two layers depended on the type of Choji. The differences of Jumchi-Hanji and Dakji were also identified in the strength properties. All Jumchi-Hanjis had low tensile and wet tensile strengths when compared to Dakjis. However, Jumchi-Hanjis, made by sixty minute Jumchchigi, had generally higher tearing, bursting, and folding strengths than the Dakjis. In conclusion, the strength properties of Jumchi-Hanji could be improved by controlling the number of Dakji layers and the time of Jumchichigi.

This study examied ned physical properties and surface characteristics of papers post-processed by Jumchi technique and stainability of extract from Amur Cork-Tree to use Dakji as clothing material. Then, it found the following results. After-treatment by Amorphophalus konjac K. Koch and persimmon juice showed stronger tensile strength and tearing strength than untreated samples and the drape stiffness was substantially increased. After-treatment by persimmon juice generated dyeing effects as well as excellent tensile strength and tearing strength all samples were generally dyed well by Amur Cork-Tree, While the untreated samples did not show any significant effects in dyeing for more than 5 minutes. It was found that after-treatment substantially contributed on concentration of dyeing as dyeing amounts of post-processed samples were gradually increased as time increased. After-treated sample with agar did not show any significant differences from untreated sample. Accordingly, it has to be studied further.

This study analyzed differences between Jumchi-Hanji papers not dyed and dyed with persimmon juice (50% concentration) in five strength properties (tensile, wet tensile, tearing, bursting, and folding strengths). For the analysis, the undyed and the dyed Jumchi-Hanji papers were made by Jumchichigi during 40 minutes and made with the Dakji of different layer (a layer, two layers) and Choji method (Oebal-teugi, Ssangbal-teugi). Differences between Jumchi-Hanji papers dyed with the different concentration of persimmon juice (20% vs 70%) in the five strengths were also identified. For this examination, Jumchi-Hanji papers were made with two layer Dakji (Oebal-teugi Choji method) and by Jumchichigi during 60 minutes. Jumchi-Hanji papers made in this study were used as test samples. As a result, Jumchi-Hanji papers dyed with persimmon juice had higher tensile strength (CD), wet tensile strength (MD, CD), and bursting strength than those of undyed Jumchi-Hanji papers. However, tearing strengths (MD, CD) of dyed Jumchi-Hanji papers were lower than undyed Jumchi-Hanji papers. Folding strengths (CD) of dyed Jumchi-Hanji papers were low but the folding strengths (MD) of them were high compared to undyed Jumchi-Hanji papers. In addition, the concentration of persimmon juice influenced the five strength properties of Jumchi-Hanji. The tensile, wet tensile, and bursting strengths of Jumchi-Hanji papers dyed with a 70% concentration were higher than those one of Jumchi-Hanji papers dyed with a 30% concentration while the tearing and folding strengths of Jumchi-Hanji papers dyed with a 70% concentration were lower than Jumchi-Hanji papers dyed with a 30% concentration.

채색문화유산은 종이, 견, 나무, 흙, 회 등 다양한 재료를 바탕재로 사용하여 그 위에 먹 등으로 밑선을 그리고 여러가지 색료를 이용하여 선이나 색채를 표현한 것이다. 먹선은 본래의 도상을 확인할 수 있기 때문에 모사와 보존처리 시그 중요성이 강조되고 있다. 이에 적외선 촬영을 이용한 먹선 분석이 광범위하게 수행되고 있다. 본 연구에서는 채색문화유산의 바탕층 재료에 따른 적외선 촬영법을 사용한 밑선의 검출 영향을 연구하였다. 확인에는 적외선 촬영법에 사용되는 적외선 카메라와 950~1700nm영역을 검출할 수 있는 초분광 카메라 2종의 검출기기를 이용하였다. 밑선 검출을 위해 지류(닥지, 쪽/닥지), 직물(견, 견/연백), 목재(뇌록/목재), 토벽(뇌록/토벽), 회벽 7종의 바탕층 위에 먹으로 '검(檢)'을 표기하고 진사, 석황, 석록, 석청, 연백, 연단 6종의 상부 채색층을 구성하였다. 시료 제작 후 적외선 촬영법을 이용하여 밑선을 검출한 결과는 다음과 같았다. 지류와 직물 바탕재의 경우 먹선 검출에 미치는 영향의 차이가 미미하였으며, 지류에 쪽을 염색한 경우와 견에 연백으로 배채한 경우에도 큰 차이점이 확인되지 않았다. 단, 목재, 토벽, 회벽의 경우 먹선 검출에 큰 영향을 미치는 것으로 확인되었다. 특히 뇌록을 가칠로 적용한 목재와 토벽의 경우 6종의 상부 채색 안료에 대하여 모두 먹선이 검출되지 않았으며, 회벽의 경우에는 석록을 제외한 모든 상부 채색 안료에서 먹선 검출에 보다 긍정적인 영향을 미치는 것으로 확인되었다. 본 연구를 통하여 바탕층의 재료에 따라 먹선의 검출 효율에 미치는 영향이 확인됨에 따라 채색문화유산 조사 계획수립 및 결과 해석에 활용될 것으로 기대된다.

In the Korean literature, records of systematic gold thread manufacturing such as gold foil(金 箔匠), gold foil bonded with fabrics(付金匠), gold foil bonded with paper materials(金箋紙匠), refining gold(鍊金匠), cutting gold(裁金匠), and making gold thread(絲金匠) can be easily found. We can infer from these literatures that the Korean people used to make gold threads. However, is not existent the gold thread making technique. Thus, a research was done using 67 pieces of gold thread artifacts used in textiles craft of Korea, China and Japan. The purpose of this research was to identify the characteristics of the Korean gold thread by studying the artifacts' form classification, gold foil, glue and the base. First, gold thread is divided into flat gold thread and wrapped gold thread. Wrapped gold thread was made in more various methods such as with a paper on the flat gold thread, metal thread and wrapped gold thread with gold foil on top. Compared to the flat gold thread, wrapped gold thread uses a thread that has a thinner and wider. Through this analysis, even making of the base of the gold threads was different according to the type. Secondly, we looked into the characteristics of materials according to form structure of the gold thread. After analysis of experiment results, we could know that to attach Korean gold thread, glue and the mixture of materials such as Red soil(朱土) was also added. The kinds of the base of gold threads were identified as paper, leather and intestines. Among those materials, for paper, Korea's Dakji, China's Sangpiji(桑皮紙) and Jukji(竹紙) and Japan's Anpiji(雁皮紙) seemed to have all been used, so because of the difference among countries, we can prove that Korea has also produced gold thread. By looking at the research, the base of gold threads and making features hugely vary according to the area.
