  • To utilize hanji for fashion accessory efficiently, dyeability of Hanji should be improved. Though Hanji mostly consists of cellulose such as cotton and ramie, also has various impurities, and has the different internal and surface structure from textile materials. Because of them, Hanji might show different dyeing behavior. As physical properties of Hanji are reduced in wet condition, dyeing process would damage the physical properties of Hanji Therefore, in this study, dyeing properties of Hanji using direct dye were examined in comparison with cotton and ramie. Effect of dyeing on tensile strength, and bleeding of direct dye by water from Hanji, colorfastness to light were also estimated. While Hanji showed the maximun dye exhaustion at $25^{\circ}C$, cotton and ramie showed those at $60^{\circ}C$. Tensile strength of Hanji reduced after Hanji was dyed. When Hanji was dyed at $25^{\circ}C$, the more bleeding occurred than at higher dyeing temperature. Hanji which had higher K/S values were bled more than those had lower K/S value. Colorfastness to light of Hanji dyed with direct dye was not inferior to those of cotton and ramie.

  • This research was performed to investigate the physical properties and color appearance of Hanji manufactured using bast fibers dyed separately by two reactive dyes with different colors. The breaking length of color Ha was above 7 km. The fastness was five grade; the use of reactive dyes made the color of the Hanji not to be faded away. The Hanji manufactured by mixing uniformly two types of bast fibers separately dyed showed the mixed color of two different colors. However, the shives showed their original colors, resulted in irregular color patterns all over the sheets. The color of color Hanji with different colors in the front and back side of sheets showed color difference between front and back side of the sheets. Accordingly, the color of the sheet has a reflection from the backside, resulted in Pink. The colors of the Hanji appeared in this study could not be found from the Hanji manufactured by traditional methods.

  • The physical and functional properties of various woven fabrics with Hanji/cotton and Hanji/silk were examined. The tensile linearity, tensile resilience, bending rigidity, bending hysteresis and shearing stiffness increased with increasing Hanji yarn content. On the other hand, the compression linearity and coefficient of friction decreased with increasing Hanji yarn content. Grade 4-5 or 5 on the abrasion resistance and pilling test were obtained in six samples. The drape test showed that the flexibility of the samples was affected by the Hanji yarn content. Moreover, the shape of the samples showed anisotropy with increasing Hanji yarn content.

  • Hanji has been used mainly for preservation paper because of superior mechanical properties. However, it was not used in printing for inkjet and laser printer-printed letters. In this study, machine-made Hanji was prepared with five different contents of paper mulberry 20, 40, 60, 80 and 100% and managed by same pressure calendering. By increasing of paper mulberry contents, tearing index and folding endurance of machine-made Hanji increased because of increased fiber-to-fiber bonding. Printability property of machine-made Hanji improved by decreasing of paper mulberry contents. After 20 hours accelerated aging, the initial folding endurance of machine-made Hanji was reduced by approximately one-fourth degree. Between 40 and 100% contents of paper mulberry was showed similar levels about preservation property. The machine-made Hanji of paper mulberry 60% content was suitable for permanence and printability properties using preservation paper and printer-printed letters.

  • This study was carried out to develop a new application field of traditional Hanji and obtain the basic data for producing functional Hanji using sawdust ceramics and rice-husk ceramics as an architectural material. The results measuring water vapor permeance and water vapor absorption for using window materials and wallpapers are as follows. Hanji wallpaper has good things in controlling indoor space comfortably. Particularly, ability of controlling humidity of Hanji wallpaper affects indoor space comfort and human health. In the case indoor humidity is higher than outdoor humidity, according to the addition of ceramics, Hanji wallpapers maintain the humidity by retaining water vapor molecules in the pores of ceramics. Thus the Hanji wallpapers with ceramics, in particular rice-husk ceramics, make it superior to non-ceramics Hanji wallpapers in maintaining the humidity indoors.

  • The Hanji dyed with persimmon juice were useful goods in the past, but they are not widely used nowadays despite of their many strong points such as antibacterial and water-resistant properties. The object of this study is to provide useful data for developing new products by using them. We dyed traditional Korean hand-made papers (Hanji) with colorants extracted from fruits of Diospyros kaki and investigated the effect of various dyeing factors (mordant, mordanting method, pH of dyeing solution, light exposure time etc.) on optical and mechanical properties of the dyed Hanji. Changing mordant affected the color of dyed Hanji. The dyed Hanji after-mordanted with Cu mordant had the highest K/S value and showed the deepest yellow and red shade. The best mordanting method was an after-mordanting. The K/S value of dyed Hanji increased with decreasing pH of dyeing solution. The tensile index and size degree values of the Hanji were increased after dyeing.

  • 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).

  • The purpose of this study is to reevaluate the performance of Hanji as a architectural material. Recent studies report that one of the causes of the Sick-HouseㆍSick-Building Syndrome is due to the contaminants from interior materials and the lack of ventilation. In this study, the properties of Hanji are investigated. The major focuses of this research are (1) how efficient the Hanji is for ventilation of the house and (2) whether the usage of Hanji brings required ventilation volume to the house. According to the test results, differential pressure in the air and the amount of ventilation showed linear relationship. Test results differ from various kinds of Hanji. Since houses usually have double window system, Hanji can be used to the windows system, especially for inner part of double window system. It is suggested that the combination of Hanji windows for the inner part and glass windows for outer part is very effective, and offers a solution to improvement of indoor air quality and the lack of ventilation with passive ventilation that has less energy consumption.

  • The optimum dewaxing ratio in dewaxing treatment by the heat and pressure method was investigated by considering aging stability of dewaxed Hanji. Commercial Hanji was coated with beeswax and thermally aged at $150^{\circ}C$ for 24 hours. Then it was dewaxed using the laboratory sheet press equipped with hot plates on both top and bottom sides. Dewaxing ratio was controlled by pressing temperature and time. Four type of dewaxed Hanji samples with different dewaxing ratio were prepared and thermally aged at $150^{\circ}C$. Then the aging stability of dewaxed Hanji samples was evaluated in terms of optical and strength properties. It was found that the aging stability of dewaxed Hanji was superior with higher dewaxing ratio. The result concluded that, in the aspect of aging stability, the coated beeswax in beeswax-treated Hanji shall be completely removed if the coated wax would be dewaxed.
