  • This study was carried out to investigate the characteristics of the Hanji which had been used for movable types printing volumes of the Joseon Dynasty. A total 29 volumes which had printed with metal and wooden movable types, were examined on the physical properties, fiber morphology, and color reactions. The grammage of all of the Hanji which had been used for movable types printing volumes were $13.10-51.65g/m^2$ and on the average was $25g/m^2$. The apparent density of the Hanji was $0.23-1.65g/cm^3$ and on the average was $0.4g/cm^3$. In almost all movable types printing volumes, the Hanji had undergone Dochim which is a processing of printability improvement. Through the examination on fiber morphology and color reactions, Hanji was investigated into that all of those were made from paper mulberry bast fiber.

  • 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).

  • 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.

  • The purpose of this study was to estimate natural dyeing properties of Korean traditional paper (Hanji). We dyed the Korean traditional paper with dyestuff which extracted from wood meal of Cotinus coggygria Scop (smoke tree) using hot-water, ethanol and $K_{2}CO_{3}$ solution. As mordants, 0.5% of $AlK(SO_4)_2$, $FeCl_2$, and $CuCH_3(COO)_2$ solution were used respectively. The color of dyed Hanji mainly depended on not the methods of extraction but the kinds of mordant. The dyed Hanji mordant with $AlK(SO_4)_2$ colored vivid yellow, $FeCl_2$ colored dark olive, and $CuCH_3(COO)_2$ colored brown and/or orange. The dyed Hanji with hot-water extractive had the highest K/S value and ethanol and $K_{2}CO_{3}$ solution extractives were followed. The K/S value of dyed Hanji mordant with $AlK(SO_4)_2$ was higher than that of $FeCl_2$ and $CuCH_3(COO)_2$. The dyeing effectiveness of after-mordanting method was superior to the others but sim-mordanting method was the worst.

  • Hanji(Korean traditional paper) is a valuable cultural heritage highly praised, even to this date, for its importance and technology by craftsmanship of our ancestors; it is a product of a combination of craftsmanship, well-established technologies, natural paper mulberry fiber and eco-friendly and durable natural materials and mucilages. Origin of the word 'Hanji(Korean traditional paper)' is from handmade paper made of bast part of the paper mulberry; as paper manufacturing with paper machines introduced in Japan was adopted in late Joseon, paper produced previously was called 'Hanji' and paper produced with western machines was called 'Yangji(machine made paper)'. Hanji has been called by many different names and used in various ways according to materials and production methods; and the functions varied. Hanji, from the era of three states to Joseon era, has been praised for its unique and excellent quality in three Asian countries(Korea, China and Japan); its unique excellence continues to this date in many paper-related national cultural heritages. Also total of 11 cases are registered to UNESCO Memory of the World for its importance, 8 of which are associated with traditional Korean paper: Hunminjeongeum, the Annals of the Joseon Dynasty, Jikjisimcheyojeol, Seungjeongwon Ilgi, the Royal Protocols of the Joseon Dynasty, Donguibogam, Ilseongnok and A War Diary. To examine excellent characteristics of conservation science in Hanji, many studies have been developed. By developing analysis and manufacturing technologies, the excellence of our Hanji should be re-verified scientifically and the tradition should continue as one of the representative Korean cultural heritages.

  • Hanji(Korean traditional paper) is made from bark of paper mulberry(Broussonetia kazinoki). For a long time, Hanji has been used in various fields, such as paintings, printing paper, as specialty paper. The utilization of Hanji will become more and more diverse. One of the characteristic properties of Hanji is a long life time comparing to western paper. The mucilage which must be used in Hanji manufacturing should effect the conservation properties of Hanji. The effectiveness of the mucilage in aging of Hanji was evaluated in this paper. Strength properties of thermal aged Hanji made with synthetic mucilage decreased more slowly than those of Hanji made with natural mucilage. As prolonged aging time, all Hanji made mucilage increased oxidation index. But, Hanji made with PAM was most stable in oxidation of cellulose.

  • The annals of Joseon Dynasty is the most valuable resource containing the record of Korean history and has been known as one of the UNESCO's Memory of the World Register. In some period, wax-treated paper was used in the annals of Joseon Dynasty to prevent the damage from pests. But, wax-treated volumes were discolored to brown, white or black, and partially cracked by the stiffened wax. It means that wax-treated volumes were damaged by the hardening and oxidizing of wax. The wax is considered as the first reason in damages on the wax-treated volume. Therefore, in this study we analysed the oxidation index of Korea traditional paper(Hanji) which is used as the restoration paper of the waxed volume in the annals of Joseon Dynasty by using FT-IR. As the analysis of FT-IR, the traditional two-layed stamping paper (Hanji sample F), which was treated by starch in its surface, was shown the most stable state after the accelerated ageing test.

  • This study was carried out to investigate the papermaking characteristics of paper mulberry(Broussonetia kazinoki) for new Korean traditional paper(Hanji). Hanji has been traditionally made only with the bast fiber of paper mulberry. Besides mulberry bast part, wood core was utilized separately or in mixed forms as raw materials for the new Hanji. Hanjis made from the solfomethylated pulp were shown higher brightness and sheet strengths than those from alkali and alkali-hydrogen peroxide pulps. The brightness of solfomethylated pulp was found to be high enough not to need additional bleaching. In the physical properties of the Hanjis mixed with bast part and wood core pulps, the handsheet strengths were decreased as the increase of the wood core pulp contents. But the sheet strengths of Hanjis containing 10∼30% of wood core pulps were higher than those of the Hanji containing bast part pulp only. The sheet formations were improved as the increase of wood core pulp contents, while the sheet strengths were decreased.

  • 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.

  • This study explores standardization plans concerning industrialization of Hanjii which is traditional culture resources of rural community. Hanji is very useful in many ways, and its usefulness is not confined to only paper. In other words, it comes to have architectural uses, agricultural uses, clothing uses, and medical uses through fusion and convergence. However, the expansion of Hanji market dose not lead to profits for related stake holders because its standardization is not nurtured yet. For standardization, this paper argues, first, a industrial definition of Hanji is needed in which Hanji's own characteristics is involved. Besides maintaining traditional characteristics, the definition and quality standards of Hanji needs to be established by considering a given condition of Hanji industy. Second, a satisfactory method to measure Hanji's own material characteristics(i.g., mulberry paper content and long-term sustainability), which affects Hanji's quality, needs to be developed and standardized. Third, a government standard is urgently needed in order to keep consumers from being confused when they select Hanji products. The standardization of Hanji products and technology needs to be established in both case of current Hanji market and newly developed products and technology.
