  • Natural preservative agents are generally made of antibiotic substances that are extracted from plants. They are used mainly to keep in an original good state food, natural cosmetic goods and medicines which are likely to get rotten. The purpose of this study is to investigate whether natural preservative agents can be applied to fabrics for the preservation of textile cultural properties. For the purpose, this researcher experimented with a certain natural preservative agent which was developed to preserve natural cosmetic goods. The study found that when treated with the foresaid natural preservative agent whose ratio to water was 1%, fabrics showed little changes in color and tensile strength, almost neutral pH, high antibiosis and anti-fungus and high resistance to Bacillus cereus that is much detrimental to silk fabrics. As a part of the study, a preliminary test on the possibility of using natural preservative agents to preserve textile cultural properties, found that when kept covered up with the 1% natural preservative agent-treated fabrics for 72 hours, excavated textile relics showed a dramatic decrease in microbial growth.

  • Wood vinegar and Asarum sieboldii Miquel were selected as candidate materials showed antimicrobial activity and insect repellent activity. These natural pesticides have its own color and these could cause color difference on fabric materials. In the present study, we investigated the color difference of undyed and dyed fabrics to evaluate negative effect of wood vinegar and A. sieboldii Miquel. Undyed and dyed fabrics were exposed to natural pesticides of various concentrations for six months in relative humidity 70% and temperature $28^{\circ}C$. After exposure of pesticides, color difference (${\Delta}E*$) were investigated at two weeks intervals for six months. As a results, dyed cotton, silk and undyed silk fabrics exposed wood vinegar were not nearly changed in their colors, but color of only undyed cotton fabric was clearly changed by wood vinegar. Especially color difference by wood vinegar on undyed cotton fabric was most distinct as the concentration increased. On the other hand, all of fabrics exposed A. sieboldii Miquel were not nearly changed in their colors for six months. Therefore, this study first suggests that wood vinegar and A. sieboldii Miquel as natural insecticides could be used to conserve for textile cultural properties from insects and microorganism, but wood vinegar couldn't use the high concentration on undyed cotton fabric.

  • To conserve historic textiles, analyses of textile materials, pollutants and deterioration are prerequisite steps. Based upon analytical results, guides for conservation of historic textiles are established. In analyses of textile materials, pollutants and deterioration, there are chemical methods(burning, solubility and staining), physical methods(microscopy and density) and instrumental analysis(Fourier Transform Infrared Spectroscopy (FT-IR), Fourier Transform Raman Spectroscopy(FT-Raman), Gas Chromatography(GC), Mass Spectroscopy(MS), X-Ray Fluorescence (EDXRF, WDXRF), Energy Dispersive Spectroscopy(EDS), and X-Ray Diffraction(XRD), Tensile Testing Machine etc.). Combination of qualitative and quantitative analyses makes accurate diagnosis of textile condition possible. As examples of analyses and conservation of historic textiles, Chuninsan(19 century) similar to sunshade with handing down historic textile and golden decorative skirt(17 century) with excavated costume are taken.

  • This study was performed to characterize historical paper artefacts from 16th to 19th century from Chungbuk National University Museum (CNUM) in Korea. In order to know the fiber composition, surface features and fiber orientation in historic paper artefacts, LM, SEM and EDX analysis observations were applied. Based on tested results, it was concluded that Korean historic papers from 16 to 19th century were made of paper mulberry fibers called dak, which had 2.79-16.03 m of fiber lengthes and $4.5-26{\mu}m$ of lumen widthes, and they were relatively well preserved. According to EDX analysis, the examined papers differed to the contents of inorganics. High contents of S, Si, Ca, P and Al refer to use fillers, such as gypsum, clay and talc, for paper artifacts. In particular, half of samples contained some amounts of S, Cl and Fe. Since those inorganics might be potentially harmful for the paper permanency, therefore it should be considered special restoration measures from the preservation point of view.

  • The research on the conservation of the movable modern and contemporary cultural heritage have been actively performed internationally since late 20th century. In this study, the international research trends of movable modern and contemporary cultural heritage conservation in last decades were analyzed. Setting up the range of the period, research papers were collected through various databases based on the systematic literature review process. Samples of 45 domestic papers and 505 foreign papers were classified by materials as books and paper, metals, textiles and fibers, photographs and audio-visuals, woods, plastics and ceramics and glass. The types of treated artifacts, detailed materials of the treated artifacts, and the research subjects were investigated from each paper. The data were compiled statistically and analyzed. Number of papers are published domestically in the book and paper conservation and metals conservation fields, but there are needs for more diversified artifact types and extensive research subjects. The researches in foreign countries are active in conservation of organic materials such as paper, textile and photographs and deal with various research subjects on not only treatment techniques and elemental analysis but also preventive conservation and conservation ethics. It is expected that this study would contribute to the field as a preliminary data on the conservation of modern and contemporary cultural heritage.

  • Modern cultural heritage were made with various materials. But there are no certain analysis for modern cultural heritage. Analysis on rickshaw from National Museum of Korean Contemporary History were carried out using P-XRF, species identification, paint film analysis, FT-IR and microscope observation. As a result Copper and Zinc were measured in metal parts. Nickel alloys were first used in the modern era for rickshaw. Wooden parts, Oak(Quercus spp.), bamboo(Phyllostachys spp.) and Hinoki cypress(Chamaecyparis spp.) were identified. Outer films were painted by 5 layers and inner films were painted by 3 layers. More simple painting process were performed on the inner part. Cotton and wool were identified by FT-IR. Also, cowhide were identified. Authenticity conservation and restoration could be carried out with the results.

  • Paper, textile and wood materials are mainly consisted of cellulose. Cellulose is high molecule and make up the strong crystalline structure by hydrogen bonds. In particular, the polymerization degree of cellulose are closely related to the strength of fiber, and the permanence. the useful life of fiber, also depends on the degradation of this substance. The viscosity of cellulose is considered to be an important indicator of fiber damage in high molecule polymers. The viscosity measurements with CED solution is used to measure the molecular weight and the degree of polymerization of cellulose. Cellulose viscosity of wood fibers is measured with TAPPI standard method T230. However, TAPPI standard method T230 is difficult to completely dissolving the cellulose of high molecular weight and large degree of polymerization, such as Korea traditional papers and fabrics made with mulberry, ramie, cotton fibers. In this study, The high viscosity of hanji and fabric was measured with TAPPI standard method T254. T254 method is that the cellulose specimen with the proper amount of weaker (0.167M CED) solution, and completely dissolved with the stronger (1.0M CED) solution. It was found that cellulose with high degree of polymerization was dissolved more easily in general CED method.

  • Samsebul, the altar portrait behind the statue of Buddha in the main building of Bonghwang temple in Andong, has been designated as Tangible Cultural Property No. 406. These alter portraits have significance as the standard of the research of Samsebul in Joseon period. In this study, fibre of the ground textile is identified using microscopic examination, solubility test, ATR-FT-IR, SEM, XRD. Two samples from Yaksabul(A, B), one sample from Seokgabul(C), and one sample from Amitabul(D), which were collected during the conservation process, were prepared for this study. In previous record, above samples were documented as hemp. Due to severe deterioration and accumulated dust layers on these samples, it was hard to recognize them with naked eyes, but through this study, we could identify that all samples except one from Yaksabul(A) are silk.

  • This study was conducted focusing on the stability on materials of cultural property when the fumigant containing ethylene oxide was applied among some kinds of fumigant. Four kinds of specimens from paper, textile, metal and pigment were prepared to compare color difference, weight, surface condition before and after treatment and FT-IR analysis was carried out on specimens of paper and textile. In the case of fumigation treatment, it was conducted by two groups : one is made up of specimens with the non-fumigation as control groups, the other is made up of specimens treated with ethylene oxide + $HFC_{134a}$ and ethylene oxide + $CO_2$ as experimental groups. The result of color difference showed that there were color differences on the specimens of Hanji(Korean traditional paper), silver, cotton, ramie and yellow pigment. Especially, it was found out there was color change more than 6.0 on average from the silver specimen. However, in the silver specimen's case, color change in the non-fumigated specimen was relatively higher than those of fumigant-treated specimens, therefore, it is judged that fumigant doesn't have a decisive effect on color change in specimens, but required caution while fumigating. The result of weight measurement, there were totally 0~2% weight changes and the slightest change was found in the metal specimen, the biggest change in the papers. The result of microscopic observation on the surface of specimens showed color changes and especially, the biggest change on the silver specimen was observed. But no change in components was identified from FT-IR analysis of papers and textiles.
