  • Many researches for extensive uses of Hanji have been performed. With the advent of an information-oriented age, the development of Hanji which is printable has been considered as a new field of study. Since Hanji has many drawbacks in comparison with common printing papers, that is, rougher surface, huger absorption of ink and lower physical properties and printabilities. Improving the properties and printabilities of Hanji is therefore the most important work to deal with. This study was conducted to find out useful mixed agents for surface sizing suitable for printable Hanji. Four surface sizing agents (CMC, corn starch, PYA, AKD) were applied for mixture in this study. The physical properties of surface sized Hanji were measured. Results obtained were as follows. Based on designated agents according to concentration, each of the mixed agents was prepared. The kinds of mixture were corn starch (3%) and PVA (5%), corn starch (3%) and AKD (0.1%), corn starch (3%) and CMC (1%), AKD (0.1%) and CMC (1%), AKD (0.1%) and PVA (5%), CMC (1%) and PVA (5%). Each mixed surface sizing agents was included with these ratios (100:0, 90:10, 70:30, 50:50, 30:70, 10:90, 0:100) respectively. All the mixed agents improved the physical properties and printabilities of Hanji. Among them, mixed agent of CMC (1%) and corn starch (3%) with 90:10 ratio is superior to the others for not only smoothness but also ink printability. In view of the result achieved, it is regarded that it can be fit for using Hanji as a printing paper and turned out to be a good contribution to Hanji industry.

  • This study researches the current status of shrouds and analyzes the current status of the Hanji shrouds and sets its goal on suggesting the direction for a futuristic shroud design, suitable for the changing funeral culture. For this, the characteristics of traditional shrouds were studied, standard shrouds' and Hanji shrouds' current statuses were researched and analyzed to suggest the development diretion for design of Hanji shrouds. The results of the research showed that the Hanji shrouds are superior in cremation and burial, and the design expressions were more effective. Also the previously established shrouds were shown to have an increase in value through use of different materials, changing designs through various patterns, or through the added symbolic value. Thus the direction of shroud development designs based on the advantages of Hanji have been drawn out to as follows: First, traditional shrouds used the ceremonial dresses, such as official uniforms or wedding dresses, from the Tang dynasty which made it multicolored. Afterwards colors were limited with the use of hemp clothes shrouds but with the appearance of Hanji shrouds, the possibility for mulitcolors and patterns became larger. Second, Hanji is superior in its expression of colors and patterns, making designs with symbolic sides such as religion possible, to meet the demands of the customers. Third, Hanji shrouds are more environmentaly friendly than the standard shrouds in cremation and burial, and it presents a much better image of shrouds for the future society. Such development of Hanji shrouds design developments satisfies the distinct and gentrified demands of the customers and it looks to be able to suggest an opportunity for environmentaly friendly actions while preparing itself for the chaning market demands and values.

  • To investigate the dying properties of the extracts from different parts of Neolitsea sericea Koidz on Hanji, the dye materials were prepared from the extraction methods using $1{\ell}$ of hot water and alkaline solution with 40 g of leaves, bark, and wood each. K/S values and H (V/C) values of the Hanji dyed at different pH, temperature, time, and concentration of extract were determined using a spectrophotometer, and the maximum absorption wavelength of the dyed Hanji was 400 nm. From the analyzed data, the optimum dying conditions were pH 5 of dying solution, $70^{\circ}C$ of dying temperature, 40 minutes of dying time, and 100% of dye concentration. The color of dyed Hanji was Y to YR and color R- and RP-type could also be formed from the different treatment conditions. From the dyeing using mordants, amount of the bound dye materials was high in the pre-mordanted Hanji and in Hanji treated with extracts from the leaves. Also, the amount of the bound dye materials in the pre-mordanted Hanji was higher when aluminum and iron mordant was used rather than other mordants. Not likely with this, amount of the bound dye materials in the post-mordanted Hanji was higher when copper mordant was used. In color, Hanji treated extracts from the leaves appeared as Y-type and ones treated with extracts from bark and wood showed YR-type.

  • This research was conducted to investigate the physical properties of Hanji made using maize, konyaku, and wheat powders at various concentrations. Regardless of the starch types, the most effective concentration to increase the physical properties of Hanji was 2 percent. They were significantly improved even at the treatment conditions of 0.1 percent. All the Hanji treated showed the increase of the breaking length, bust index, and tear index and the decrease of the folding number. The strength properties of the Hanji treated were markedly improved at 8 to 10 percent weight increase. The highest mechanical properties were found in the Hanji treated with konyaku powder.

  • Jeonji technique was widely used in general Hanji handicraft including Jihwa handicraft. But the technique itself has not been passed on. By contrast, Jiseung technique and Jiho technique have been passed on and continuously developed. And although the Huji technique has not been transmitted, it should be vigorously used as a technique of producing the frame in order to revive the authenticity of traditional Hanji handicraft. Jumchi technique, a method of using water to connect between layers, is an effective technique of diversely expressing the feel of materials of Hanji craftworks. Modern Hanji handicraft has used the characteristics of paper and paperboard diversely produced nowadays as much as possible, which shows that it is more likely to develop as handicraft.

  • Owing to formation of fiber fibrillation and application of binder bonding, pressing device, and curing process, the characteristic of prepared Hanji(korean traditional paper) is a thin structure, relatively high tensile strength and stiffness. To predict tensile property of Hanji, in the present work, a theoretical equation including tensile property of fiber, curl factor, orientation distribution function, and Poisson's ratio of Hanji was derived in consideration of fiber stress limit, slippage effect, and thickness. For accurate tensile property of Hanji, new definition of fiber stress limit was introduced. By applying the concept of finer tape yarn and thickness factor, this paper modified the earlier prediction theory of tensile stress of the nonwoven fabrics. In a next paper, the comparative analysis between this theoretical theory and experimental tensile behavior of Hanji will be discussed.

  • This study was carried out to explore a new application of traditional Hanji and obtain fundamental properties for producing Hanji wallpaper by incorporating ceramics from wood and rice-husk as an interior building material. The results of properties determined were summarized as follows: The addition of ceramics in Hanji paper reduced its apparent density, but increased bulk density due to the ceramic particles distributed on the surface and inside the fiber of Hanji wallpapers. In particular, woodceramic particles were specifically distributed on the fiber surface, while particles of rice-husk ceramics were permeated into the inside surface of fibers. The density of rice-husk ceramics were greater than that of woodceramics. The physical properties of Hanji wallpapers, such as breaking strength, wet breaking strength, burst strength, tear index and folding endurance were deteriorated with the addition of ceramics. However, the addition of woodceramics in the Hanji wallpaper resulted in better strength in most cases than that of rice-husk ceramics, except tear strength. Therefore, an optimum addition level of woodceramics into the wallpaper was found to be 5% on the basis of intensity. The addition of ceramics also prolonged the combustion time because it lowered air permeability and brightness of the wallpaper.

  • 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.
