This study was carried out to investigate the making method and properties of Hanji(Korean traditional paper) for wallpaper for the purpose of mass production and mass consumption of Hanji. Paper mulberry fiber was longer than wood fiber in length and it had also much extractives and ash in content. Bast fiber was a little damaged in the fibrilation and beating process because it was weak in flexibility and compressive properties. Proper conditions for making two-ply and three-ply Hanji were examined and six kinds of Hanji were made on the basis of the three-ply paper making method. The sample OH(Original Hanji) 2-2 and OH 3-2 among them obtained good results in quality test by appearance from wallpaper makers.

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 develop the manufacturing technique of Korean paper(Hanji) and find out new uses of machine-made Hanji produced on a a large scale by paper machine. Six kinds of Hanji were made and laminated with backpaper by acryl-based or vinyl acetate ethylene-based adhesive. Six kinds of wallpapers were made such as WH 1, WH 2-1, WH 2-2, WH 3-1, WH 3-2 and WH 4. Physical properties and quality test on the wallpapers were examined. Physical strength of the wallpapers was better than each strength of the Hanji and backpaper. It might be a roll of adhesive. And so, Production cost of the Hanji could be brought down if the Hanji was made thin to get strength not enough to cut during lamination of two papers(Hanji and backpaper). Hanji wallpapers of WH 3-1 and WH 4 are lower than a standard in sunlight resistance and WH 1 is in properties of opacity. WH 2-1, WH 2-2 and WH 3-2 were better than Korean standard in some quality tests. WH 2-2 and WH 3-2 were superior to other wallpapers as a whole. About, twenty kinds of wallpapers with surface treatment, are now being produced on the basis of these two types of wallpapers.

The sound absorption property, hand feel, air permeability and pore size of 25 kinds of traditional Korean natural wallpapers (Hanji) were measured and analyzed in this study. The sound absorption rate of Hanji became larger with increasing of frequency beginning from 3.2 kHz, reached 2 times in frequency range of nearby 4 kHz. The sound absorption rate of Hanji was increased as the permeability was lowered and the pore size was decreased. The sound absorption property of Hanji wallpaper could be improved by manufacturing process such as super calendering process.

In this study, we used various dyes from natural pigments such as tumeric, goldthread, indigo, pagoda tree flower, sappanwood, and safflower to make the Hanji wallpaper with super eight colors of yellow, orange, green, turquoise, violet, red, blue, and magenta. As a result of measuring the lightfastness, magenta dyed with sappanwood showed the worst effect, but blue dyed with only indigo showed the best effect. In terms of the spot test by water, red wallpaper dyed with safflower showed the clear spot, but blue, turquoise, and green dyed with indigo resulted in a little spot. The orange, violet, and magenta dyed with goldthread and sappanwood showed antibacterial activity, and the turquoise, green, and blue also has a little antibacterial activity. However, yellow and red didn't show the some result as expected. In the experiment for efficiency of formaldehyde removal, all Hanji wallpapers dyed with natural pigments showed the significant removal effect of formaldehyde, especially turquoise and red were the highest.

본 연구에서는 조선시대 후기부터 현재까지 보존된 경복궁, 창덕궁 그리고 칠궁 내 일부 전각의 도배지를 채취하여 조선 왕실에서 도배지로 사용한 종이의 종류와 특징을 파악하고자 하였다. 이에 첫 번째로, 고문헌 조사를 바탕으로 왕실에서 사용된 도배지 기록을 통해 왕실에서의 도배 특성을 확인하였다. 두 번째로, 건립 시기가 비교적 분명한 전각을 대상으로 현장 조사를 실시하여 시료확보 후 초배지 분석을 실시하였다. 따라서 왕실 도배지로 활용된 한지의 주원료를 확인하였으며, 청색 장식지 분석을 통해 격식을 갖춰야 하는 공간에 사용된 청색 발색물질(염료·안료)의 종류를 파악하였다. 분석을 통해 확인한 결과를 토대로 조선시대 궁궐 도배지와 관련한 고문헌 기록과 대조함으로써 문헌의 기록과 현존 도배지 실물을 확인하고, 향후 궁궐 도배지의 보수 시 문화재 복원의 기초자료를 제공하고자 하였다. 17~20세기 영건의궤류 36건 등에 기록된 도배 관련 내용을 추출하여 시기별 도배지 종류 변화, 사용처에 따른 도배지 종류 등의 내용을 검토한 결과, 의궤 제작용 한지와 도배용 한지의 명칭이 다르지 않아 조선시대에는 문서지와 도배지를 구분하지 않고 사용했음을 알 수 있었다. 또한 시대별 도배지의 종류는 차이가 있지만 백지, 후백지, 저주지, 초주지, 각장이 도배의 기저를 이루는 것은 조선 말기까지 지속된 것이 확인된다. 궁궐 벽체와 직접 붙어있던 면의 초배지를 대상으로 섬유의 형태학적 특성 및 정색 반응(KS M ISO 9184-4: 그라프 "C" 염색 시험)을 통해 섬유 식별을 실시한 결과, 왕실에서 도배지로 활용된 한지의 주원료를 확인하였으며 전각의 건립 시기에 따라 당시 한지를 제작하는 데 사용한 지료의 원재료를 파악하였다. 또한 청색 장식지의 발색원료를 광학현미경, 자외-가시광 분광분석(UV-Vis), X선 회절분석(XRD)을 통해 분석한 결과 격식을 갖춰야 하는 공간에 사용된 청색 장식지의 염료 및 안료의 종류를 파악하였으며 청색을 내기 위한 원료로서 쪽, 청금석, 코발트블루 등이 사용된 것이 확인되었다.

The purpose of this study is to reevaluate the performance of Hanji as an architectural material. Hanji has good things in controlling indoor space comfortably. Particularly, ability of controlling humidity of Hanji affects indoor space comfort and human health. The major focuses of this experimental research are (1) how much of water vapor passes through Hanji, (2) how much of water vapor is absorbed into Hanji. In the first case, indoor humidity is higher than outdoor humidity. In this case, approximately 38 g of water vapor passes through Hanji 1, genarally utilized in window paper (Changhoji), per square meter in one hour. And approximately 4 g of water vapor is absorbed into Hanji 2, genarally utilized in wallpaper, per square meter. In the second case, outdoor humidity is higher than indoor humidity. In this case, Hanji passes water vapor to inner space at first, but when indoor relative humidity reach approximately 66%, although outdoor humidity is higher than indoor humidity, water vapor doesn't pass through Hanji. If Hanji is utilized in window material and wallpaper, indoor space is maintained comfortably without mechanical devices in humidity control.

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.
