박물관에서 소장품의 저산소 농도 살충처리를 위해, 직물, 염색 직물, 종이, 염색지 및 채색편의 색상 및 기계적 성질에 미치는 영향을 평가하였다. 저산소 농도 살충 조건은 질소 및 아르곤을 사용하여 조성한 산소 농도 0.01%, 온도($20^{\circ}C$, $25^{\circ}C$, $30^{\circ}C$), 습도 50%, 살충 시간 30일이였다. 직물은 생견 직물, 자외선 열화 생견 직물, 정련 견직물, 자외선 열화 정련 견직물, 광목 및 자외선 열화 광목을 평가 대상으로 하였다. 천연염색 견직물과 면직물은 생쪽, 쪽, 홍화, 자초, 꼭두서니, 소목, 황벽, 울금, 치자, 황련, 괴화, 코치닐, 자광, 오리나무, 오배자, 밤피 및 쪽과 홍화 복염, 쪽과 황벽 복염, 쪽과 괴화 복염, 쪽과 소목 복염 등 천연염색 직물 각 20종이었다. 평가 대상 종이는 한지(닥지, 닥과 볏짚 혼합지), 화지(안피지), 면지, 린넨지, 면, 아마 및 마닐라삼 혼합지, 복사지, 신문지, 반수 닥지 등 9종이었다. 염색지는 한지에 쪽, 소목, 꼭두서니, 홍화, 치자, 황벽, 괴화로 천연염색한 것을 평가하였다. 채색편은 반수 한지와 반수 화견에 석청, 석록, 주사, 주, 석자황, 등황, 연단, 대자, 석간주, 니람, 연지(자광, 코치닐, 홍화, 꼭두서니), 뇌록, 스몰트, 울트라마린블루, 라피스라즈리, 프러시안블루, 백토, 연백, 호분(굴껍질 호분, 대합껍질 호분) 등 23종의 안료 분말을 아교물에 개어 도포한 것이었다. 평가 대상 재료에 대해 저산소 농도 살충처리 전후의 색차를 평가한 결과, 색차 ${\Delta}E^*$는 1.5 이하이거나 대조군보다 낮았으며, 직물 및 염색 직물의 살충처리 전후의 인장강도 변동률은 기준치 이하였다. 그리고 가스(질소와 아르곤)와 살충 온도에 따른 색차 및 인장강도 변동률에 대한 영향도 없었다.

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.

The utilization of non-woody fibers with the fast growing annual plants has occurred in the paper industry to replace wood and preserve environment of the earth. The non-woody fibers generally used for papermaking are paper mulberry, gampi, manila hemp, rice straw, bamboo, and coton linter etc.. Recently Kenaf has been spot-lighted for the same application. Kenaf is an annual plant of Hibiscus species of Malvaceae family. Kenaf, a rapid growing and high harvesting non-woody fiber plant, was identified as one of the promising fiber sources for the production of paper pulp. This study was carried out to investigate the pulping characteristics of Kenaf bast fiber for Hanji (traditional Korean paper) manufacturing by different pulping methods, such as alkali, alkali-peroxide and sulfomethylated pulpings. It was possible to make superior grade of Hanji. Especially sulfomethylated pulping was resulted in superior pulp in terms of higher yields and qualities in comparison to those of the other pulping methods. Hanji from sulfomethylated pulp was shown the highest brightness of over 60% and higher sheet strength. In addition, the morphological features of pulp fibers (pulp compositions) affect to the sheet properties. Therefore the effect of fiber distribution index(FDI) which was calculated from the data of Confocal laser scanning microscopy(CLSM) on the sheet properties of Kenaf Hanji was also discussed.

Many historical archives have been deteriorated by aging with time. Various kinds of defects such as worm-hole, yellowing, brittleness are observed and their severity was dependent on raw material type, storage condition, and so on. For a long-term use and storage, a proper preservation treatment is required. Many studies on preservation and conservation have been carried out on hanji which was made from mulberry fiber, but there are few concerns on foreign paper. Therefore, aging and chemical strengthening treatment was done on paper made of bamboo and wood fibers depending on aging condition, the type and pickup weight of chemicals and treatment method. When methyl cellulose was treated with impregnation or brushing, the aged paper was strengthened effectively. The strengthening effect by chemicals was dependent on the aged condition of the paper.

Hanji is a traditional Korean handmade paper, made of bast fibers of the paper mulberry. Its fiber furnish is much more expensive than wood fiber furnish. Hanji with a low basis weight requires additional opacity and smoothness for better writing and printing. Filler such as calcium carbonate can not be used to raise the opacity of Hanji because of its low retention in low basis weight paper and the high freeness of the Hanji fiber furnish. Addition of red algae pulp, which is prepared from marine red algae to the Hanji fiber furnish negated retention problems happening in the case of mineral filler addition, and produced a substantial improvement in the opacity and smoothness of Hanji. The higher retention was due to the much larger size of the red algae fibers compared to the mineral fillers. The improvement in opacity and smoothness were also due to the shape of the red algae fibers: that red algae fibers are narrower in widths and shorter in lengths than wood fibers results in increased surface area and smoothness.

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 investgate the possiblity of using waste bamboo and bast fiber from paper mulberry for Hwaseonji production. 3 types of Hwaseonji were made in an experimental system, 100% bamboo pulp, bamboo pulp mixed with bast fiber in two different ratios, 70% : 30% and 40% : 60%, respectively. The result were as follows: 1. The chinese ink blots of Hwaseonji made from bamboo pulp only was satisfactory, but its tensile strength showed a low value. In order to improve the tensile strength, we must develope a new beating method with musilige. 2. The burst strength increased as the bast fiber content increased. But it is a special characteristic of Hwaseonji, that an even formation of paper is required. Therefore, only the short bast fiber is needed. 3. The tensile strength was raised by increasing the bast fiber content to 60%, resulting in a more durable Hwaseonji. 4. In even thickness, the higher opacity showed the more bast fiber. So the opacity of product III (bamboo: 40%, bast fiber: 60%) is the highest. 5. The commodity value of hand-made paper should be grade-up after a dedusting process.

본 연구에서는 여수 진남관 보수 정비 사업 중 발견된 상량문(1965년 기록)을 중심으로 재질의 성분분석 및 보존처리를 수행하였다. 상량문은 금속함에 말아 보관되어 있었으며, 결손, 변색, 경화, 이물질에 의한 손상 등이 확인되었다. X-선 형광분석(XRF) 결과 구리(Cu)로 제작된 금속함에서 기인한 녹이 상량문 표면에 고착되어 있었다. 상량문 표면에 대해 적외선분광법(FT-IR)과 열분해-GC/MS(Pyrolysis-GC/MS) 분석을 실시한 결과 카르보닐기와 지방산 화합물 등이 확인되어 상량문 표면 유기물은 기름 성분으로 확인되었다. 섬유 동정 결과 닥나무 인피섬유가 사용된 것으로 판단된다. 성분분석 및 상태조사, 접착제 예비 실험 등을 바탕으로 보존처리 재료를 선정하였으며, 닥섬유지와 메틸셀룰로오즈 등을 이용하여 보강 후 부분적으로 배접하였다.
