It is well known that Korean traditional Hanji have lots of predominant physical and optical properties such as high density, high air permeability, long lasting quality and lightness. The paper-making raw materials of traditional Korean Hanji are the bast fibre cooked from the Korean paper mulberry as a fibrous materials and sticky aqueous material from the root of Hibiscus anihot L. as additives for good dispersion of stock. Additionally, the mechanical properties of Hanji varies according to the cooking methods of bast tissues of Korean paper mulberry, the treatment methods of fibrous raw materials such as bleaching and refining, the wet formation types of sheet-making such as 'Oebal-chiji' and 'Ssangbal-choji', and the finishing treatment like stamping. This study was carried out to investigate and evaluate the quality properties of Korean traditional hand-made Hanji, and compared with commercial machine-made paper and modified prepared sheets. The physical quality comparisons of different kinds of Hanji were focused on the methods of hand-sheet making, the types of raw materials, the treatment of stamping, and the properties of ink reception and spreading.

전통한지 섬유질 슬러지 및 기계한지 섬유질 슬러지를 양이온 계면활성제 cetyltrimethylammonium chloride(CTAC)를 이용하여 효과적으로 제거하는 방법에 대해 연구하였다. 전통한지 슬러지 시료일 경우 고형분의 양이 약 0.08 g/L 일 때 CTAC의 농도가 $1{\mu}g/mL$ 되면 제거율이 95% 이상 되었으며, 이 때 걸리는 시간은 30초 이내이었다. 기계한지 슬러지에 대해 CTAC만을 이용하여 슬러지를 제거하였을 때 $15{\mu}g/mL$ 이상에서 90% 정도의 제거효율을 보였으나 슬러지 층이 안정하지 못하고, 부상시간이 비교적 오래 걸렸다. $5{\mu}g/mL$의 CTAC에 PAMID$^{(R)}$를 첨가하여 부상시켰을 때는 CTAC만을 이용하였을 때 보다 제거율이 증가하였으며 슬러지 층도 또한 안정하였다. 기계한지 슬러지보다 전통한지 슬러지를 제거할 때 더 효율적이었다.

We manufactured natural dyed Korean traditional paper (Hanji) for cultural properties conservation and storage with goldthread (Coptis chinensis) and silver nitrate ($AgNO_3$). Goldthread and silver nitrate are known to be an excellent antimicrobial activity. The effect of content of goldthread and silver nitrate on properties of dyed Hanji was investigated. Color strength of dyed Hanji decreased with increasing content of silver nitrate. After-mordanting with 3% silver nitrate improved lightfastness of dyed Hanji. Tannic acid treatment increased K/S value of dyed Hanji. As the amount of the increase in goldthread content was reduced silver nitrate content. Sim-mordanting method was used for simplifying manufacture process. Silver nitrate sim-mordanting method increased K/S value of goldthread than after-mordanting method.

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.

Korean traditional paper 'Hanji' made from the bark of the paper mulberry tree is a good handicraft material because of its high viscosity, durability, dyeability, toughness, flexibility, plasticity, and manipulability. Hanji has been used as a textile material such as cotton wool for protection and keeping us warm from cold weather. However, Hanji has many limitations, while other textile materials have many advantages of such as washability, being sunproof, and fast coloring. The purpose of this study is to review physical properties, formation ability, and dyeability of Hanji as a material of fashion accessary. The contents of this study are composed of 5 parts: 1. To introduce the necessities of this study, 2. To review a historical background of Hanji and to identify its physical characteristics as a fashion accessary material, 3. To review and to compare techniques such as bonding, quilting, knitting, creasing and holding, twisting, folding & braiding, paper pasting, coloring & cutting, and outwashing(?) in making Hanji fashion accessaries, 4. To review dyeing and finishing techniques to increase commercial value, 5. To identify the best fashion accessary materials made of Hanji. The most important characteristics of Hanji as a fashion accessary material are its toughness in a wet state, fast color fixing, and flexibility. Especially weaving and knitting are considered as the most desirable techniques to make fashion accessary products stronger and more practical.

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).

Korea traditional handmade paper, Hanji, has been known for more than thousand years for its high strength, high whiteness, high gloss, good ink reception and long lasting quality. Main component fiber of the Hanji is called 'Dak', which is the bast fiber of the Korea paper mulberry ($\textit{Broussonetia kazinoki}$). Dak has long fiber length, and high cellulose DP, if processed properly. The quality of Hanji is partly from the superior quality of Dak over wood fiber, and partly from the traditional papermaking process. The traditional papermaking process includes pulping, bleaching, refining, use of natural polymer, and sheet making process. Every traditional process has its special role. Comparisons between the modern papermaking technology and the traditional process were made in this study. The traditional process effectively protected cellulose DP in pulping and bleaching process, protected fiber length in refining process, and developed the high strength in the sheet forming process over the modern papermaking process.

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.
