한지는 우리의 옛 선조들의 뛰어난 기술과 장인정신으로 오늘날에도 그 가치와 기술을 높게 평가받고 있는 귀중한 문화유산으로 이는 그 시대의 장인정신과 축적된 기술, 한지제조에 적합한 천혜의 자연조건인 닥섬유와 물과 햇빛과 더불어 환경친화적이고 보존성이 우수한 천연자숙제 및 점질물 등이 잘 어우러진 산물이라고 할 수 있다. 한지는 닥나무 껍질(저피(楮皮))을 가공하여 손으로 만든 종이를 일컫는 것으로 조선 말엽 일본을 통하여 서양식 기계로 제조한 종이가 생산되면서 그간의 종이는 한지라 하고 서양의 종이를 양지라 구분하여 부른다. 한지는 재료 및 초지방법에 따라 다양하게 불리고 사용되어져 왔으며, 그 기능 또한 다양하게 활용되어져 왔다. 또한 한지는 과거 삼국시대부터 조선 시대에 이르기까지 동양 3국(한국, 중국, 일본) 중에서 독특하고 우수한 품질로 각광을 받아왔고, 오늘날 한지 특유의 우수한 보존성으로 수많은 국가지정 지류문화재들이 지금까지 잘 전승되고 있다. 아울러 세계적으로 그 가치를 인정한 UNESCO 세계기록유산에 한국은 모두 11건이 등재되었는데 그 중 전통한지로 구성되어 있는 기록물은 8건으로 "훈민정음, 조선왕조실록, 직지심체요절, 승정원일기, 조선왕조의궤, 동의보감, 일성록, 난중일기" 등이 이에 해당된다. 이러한 한지의 우수한 보존과학적 특징을 규명하기 위하여 다양한 연구 사업들이 진행되어져 왔다. 한지에 대한 분석기술과 제조기술개발, 복원기술연구 등을 통하여 우리 전통한지에 대한 우수성을 과학적으로 재입증하고 우리나라를 대표하는 전통문화유산의 하나로써 그 명맥을 유지해 나가야할 것이다.

We carried out cationization of Dak pulp (paper mulberry bast fiber pulp) which is raw material of Hanji (Traditional Korean Paper) using a (3-chloro-2-hydroxypropyl) trimethyl ammonium chloride to improve dyeability during a dyeing of Hanji with Gardenia (Gardenia jasminoides) and smoke tree (Cotinus coggygria). Fiber specific charge densities were determined using polyelectrolyte titration method and K/S values of dyed Hanji was calculated by Kubelka-Munk equation. As the result, fiber specific charge density increased with degree of cationization. Colors of Hanji dyed with Gardenia did not vary significantly with degree of cationization, but cationized Hanji dyed with smoke tree showed a large increase of a* value and reddish yellow color. After-mordanting did not decrease K/S value of dyes with cationized Hanji. K/S values of dyed Hanji decreased with increasing dyeing temperature. For smoke tree, the cationization impair lightfastness of dyed Hanji without mordant. After-mordanting with copper acetate or iron chloride improved lightfastness of dyed Hanji.

To investigate natural dyeing properties of bast fiber, properties of pre mordanting dyeing of sappan wood, gardenia and gallnut such as K/S values, developed color, and fastness were evaluated. Silk showed the most increased K/S values by pre mordanting treatment when Fe was uses as a mordant. The optimized amount of Fe was 3%. The colors of sappan wood was a series of YR. After pre mordanting treatment with Fe, the colors of bast fiber of mulberry and silk showed a series of RP, and the color of cotton showed a series of Y. The color of gallnut was a series of Y regardless of pre mordant treatment. Sappon wood (YR), gardenia (Y), and gallnut (Y) showed various colors such as YR, R, and RP, respectively. Sunlight fastness was not improved by pre mordanting treatment. The effect of pre mordanting treatment was not good. Especially the treatment with Al showed poor sunlight fastness.

Traditional Korean paper called Hanji using bast fibers from mulberry tree is made through complicated handmade works. This made Hanji very strong and exceedingly durable. Therefore it is said to last a thousand years. Such incomparable features of Hanji come from the unique sheet forming method called ouibalttugi using a bamboo screen. Excellent physical properties of Hanji reflect the wide variety of use, all central to everyday life. Despite its Excellency, the papermaking practice of traditional handmade paper, Hanji, from Korea is little known outside its country. This might be due to public apathy on Hanji in modern times. Without future apprentices dedicated to the craft, the Korean tradition able to make its soul is in danger of extinction in its homeland. Therefore more concern and more affection on Hanji is required immediately. It must be kept in mind that Hanji is our cultural heritage in pride over time.

Hanji is a traditional Korean handmade paper, which has been known in ancient Far East as excellent quality calligraphic paper for more than 1,500 year. Hanji is mostly made of Korean paper mulberry bast fibers, and if properly processed, normally lasts for more than 1,000 years with significant strength and still recognizable calligraphic writings or drawings on it. Dochim is a special way of Hanji calendering process, but is turned out to be quite different from modern calendering (machine calendering) in several aspects. In Dochim process, mechanical impacts were applied vertically to the surface of papers. Compared to the modern calendering, Dochim increased paper gloss much more, but paper smoothness a little less. By the Dochim process, densification occurred and the degree of densification was more sensitive to the fiber type in the Dochim process than in the calendering method.

The new alkali pulping process combined with electron beam treatment was applied to utilize hemp bast tissues as a new valuable fibrous resource. Hemp bast tissues have some chemical properties with high lignin contents and holocellulose not to be defiberized by alkali pulping only, compared with the bast tissue of paper mulberry. To make up for the weakness of traditional alkali pulping process, electron beams were directly irradiated into the swelled bast tissue of hemp in NaOH solution and distilled water, and then facilitated the defiberization of hemp bast tissues. The papermaking from hemp bast fibers manufactured by the combination pulping process showed good apparent density, formation structure and air permeability, and had some mechanical properties with lower tensile, tear, burst strength and folding endurance. It is finally concluded that the combination pulping process with electron beam treatment could be suggested a new alternative for non-woody fibers.

To evaluate the anisotropic characteristics of Korean traditional paper-Hanji, the physical and mechanical characteristics of hand-made hanji, and machine-made hanji were investigated in this research. The densities of copying paper and newsprint paper appeared to be two times higher than the densities of hand-made hanji using Ssangbal sheet forming and hanji made of paper mulberry fiber. The breaking length, and tear index of both Hanji using Owangbal sheet forming, and hand-made Hanji using Ssangbal sheet forming appeared to be different according to the directions in paper. The breaking lengths of Hanji using Owangbal sheet forming showed little differences according to the directions. Breaking length of Hanji using Ssangbal sheet were slightly higher than those of Hanji using Owangbla sheet forming. The breaking lengths of machine-made hanji, copying paper, and newsprint paper were two to four times higher than those of hand-made Hanji. The breaking length showed higher differences according to the direction than the tear index. The tensile strength according to the directions in paper showed significant differences (${\alpha}$=0.05) in all papers used in this research.

Material is a factor for maximizing formative aspect among fashion design factors. Therefore, central axis of modern fashion is performing various trials for escaping from existing cloth and searching for artistic value. Especially, Korean paper is a formative material, which is manufactured through traditional manual work in Korea. The material is used in various fields on the basis of its aesthetic feature. Especially, fashion field performs handcraft activity on the basis of mulberry pulp, which is a prime material of Korean paper. Because the activity can be reinterpreted by world designers, who want to find motive of fashion material in the third world, it is necessary to perform experimental study for developing expressive form on the basis of diversity of Korean paper material. Therefore, the purpose of this study is to perform experimental study by focusing on the development of Korean paper material in order to express formative feature. The study purposes are as follows. The first purpose is to reinterprete the theory through actual work of fiber formation using Korean paper in the current flow where art and design field are fused and compromised. The second purpose is to suggest vision of material development on the basis of formative feature to fashion world focusing its eyesight to Asia and the third countries. The study results are as follows. First, Korean paper has been evaluated as proper material for the fusion of design and art because of its handicraft feature, long-term preservation, heat insulation, absorption, diversity and eastern feature. Second, the study performed various trials for artistic dress material by developing 12 Korean paper works and suggested the development of new material on the basis of formative feature of modem fashion industry.
