The significance of this study is the demonstration of a new method of preservation procedure for national-treasure-class cultural-assets by examining the characteristics of the Jeogori relic, presumed to be that of King SeJo, and validating the preservation process. This Jergori as well as the wooden Munsu-donja Buddha statue from which they were found are designated as national treasure. The Jeogori relic is made of light silk and dimensions mark 77 cm in length, 67 cm in width, and 94 cm in sleeve length. It is a typical Jeogori worn in the Chosun Dynasty. Preservation procedure was in the following order: Removing dust and pollutants by vacuum, washing, removing creases, reinforcing the clothes, settling at paulownia backboard, and packing. Storage and exhibition of remains was executed with as minimal folding as possible, and microbiological damage prevention was performed by dyeing antibacterial treatment with eugenol onto supporting cloth. The relic, conservatively treated in accordance with the above procedure, is currently kept at the storage facility of the citadel Museum in the Woljeong Temple. It is displayed annually to the general public for approximately two weeks.

As the concerns over health increased in 1990's, research and development on the health material were also activated. The development of UV-cut textile became the hot issue, because the damage of W irradiation due to ozone depletion has become widely known. UV-cut effect is determined by the material, the color, the organization and the density of UV-cut fibers. UV-cut effect is very different according to the fibers. Polyester is known to have a better effect. Even in the same textile material, staple fiber has more effect than filament fiber. Different colors have different offsets. Although textiles have the same color, the effects can be different according to the depth of color. PET, PET/cotton blend, nylon and cotton fabrics were ultraviolet cutting finished with padding method using several absorbers. These UV-cut effect can be improved through the processing. Safety of UV-cut textile for the body must be considered future, Until now the figure of the UV-cut effects has been emphasized. There has been no experiment on the human body, although the textiles are directly on the human body. Futhermore there os no safety standard of UV-cut textiles. Therefore every effort will be made to set the standard UV-cut processing is established. The need of UV-cut products will be known to the consumers.

Lanasol dyes containing ${\alpha}$-bromoacrylamide or ${\alpha},{\beta}$-dibromopropionylamide group are used for wool dyeing. They are normally applied to wool under pH 4.5 to 6.5 at $100^{\circ}C$. Although wool fabric can be dyed to obtain deep colour, high light and wet fastness, the dyeing processes need long dyeing time at high temperature, with salt addition, which inevitably causes environmental problems. Grafting is a modification method for textile where monomers are covalently bonded onto the polymer chain. It can be initiated by ozone, ${\gamma}$ rays, electron beams, plasma, corona discharge and UV irradiation. Coloration by UV-induced photografting exhibits several advantages such as fast reaction rate, energy saving, simple equipment, easy exploitation and environmentally friendliness. Also it requires much lower energy compared to the conventional dyeing and less damage to the substrate. In this study, a direct sequential UV-induced photografting onto wool fabrics was discussed. To understand the graft polymerization mechanism further, several characterization methods were used. Moreover, the effects of several principal factors on the graft photopolymerization were investigated. Furthermore, the colorfastness results were compared with conventional dyeing methods.

This study analyzed satisfaction with and washing of newborn clothing (especially the innerwear washing behaviors) which are considered to be the most basic items among newborn clothing.The survey was conducted on mothers with children under 24 months old. Using an average of 6.7 innerwear items that were changed average 2.3 times a day with baby formula and breast milk representing the main contaminants. When washing clothes for a newborn, respondents were mainly concerned with: rinsing residual detergent, removing stains and contaminants, and sterilization and disinfection. Items were washed by a laundry label to prevent clothes damage. A baby-friendly or environmentally-friendly detergent was used to wash before being worn after purchase was separated and washed in various washing courses of the washing machine every day, boiled, rinsed an average 3.6 times, and dried mainly in the sun. Environmentally friendly cotton (59.5%) and organic cotton (41.6%) products were mainly used; however, items were washed separately from regular laundry. Respondents were satisfied with methods of washing. Consumers are concerned about washing because they think that washing affects a newborn's health. Therefore, it is necessary to provide consumers with appropriate information on washing and establish regulations for the use of harmful substances in newborn clothing and detergents.

'Burn-Out' is a kind of printing process that can create many textural effects, also high added value of the fabrics. In the previous studies, it is examined how to burn out the cellulose part of the velvet and the polyester/cellulosic fiber mixed fabric without damage of the other part and the effects of process conditions. In this study, dyeing properties of the colored burn-out printing were investigated with various conditions onto the polyester/cellulosic fiber mixed fabrics with red disperse dye. As a results, the apparent color depth (K/S) is increased with increasing of concentration of dye. The optimum treatment conditions without any shrinkage or occurrence of yellowness on the polyester ground fabrics are fixation temperature of $140^{\circ}C$ and time of 3 minutes.

The effect of sodium acetate to reduce the fiber damage and hardening of acetate fabrics during alkaline treatment is studied. The optimal condition is controlled concentration 2%, at $50^{\circ}C$ for 6 minutes and at $70^{\circ}C$ for 2 minutes through the result of weight loss, shrinkage and tensile strength. Alkaline treated acetate fabrics under optimal condition show softer than untreated acetate fabrics. Alkaline treatment with sodium acetate brings the reduction in hardening and shrinkage in internal fiber of acetate fabric. Also, alkaline treatment with sodium acetate improves the tensile strength of acetate fabrics compared with only alkaline treatment. The moisture regain of acetate fabrics is also improved by alkaline treatment under optimal condition.

This study is to make pH 9 reduction by adding NaOH to 1, 3, 5, 7, 9, 11% solution of thioglycollic acid, cysteine, cysteamin, to add it on helically winded natural hair and colored hair and leave them for 20, 40, 60 minutes, to add $NaBrO_3$ oxidant for 15 minutes and to compare and analyze the wave form. This study showed the results of permanent using thioglycollic acid, cysteine, cysteamin. In the permanent wave form according to the kind of reductant, concentration, and processing time, there were a little difference between thioglycollic acid and cysteine. But cysteamine not only showed apparent difference but also formed strong and elastic wave. The permanent wave is affected by the diagonosis of hair, the choice of permanent solution and the processing time. Therefore the scientific diagonosis of hair is to be considered first of all. By choosing the kind of solution, the concentration and the processing time according to the results of hair diagonosis and wave form, we can prevent the lengthening and damage of hair.

The purpose of study is to find out a suitable cleaning method for excavated textiles of Jeon-ui Lee(1570∼1647). The textiles were excavated from her tomb in 1997, and her descendents put them in a box without any treatment and kept them in the warehouse since then. We used two kinds of silk as samples, non-dyed and dyed textile. The experiment was performed by 8 kinds of wet cleaning and dry cleaning methods, an ultrasonic cleaner was used in the wet cleaning, decane and perchloroethylene were used as solvents in the dry cleaning. The use of the ultrasonic cleaner in the wet cleaning method did not show any damage to the fibers of the textiles and it not only cleaned well but also was safe for the fugitive dyes. It resulted in more effective cleaning when the detergent was used together. Therefore, it is effective to use the ultrasonic cleaning on the delicate historical textiles and helpful to the operator's safety and environment.

In this study, we investigated the effects of oxidative permanent hair coloring agents on the dyeability and the damage of human hair. p-phenylenediamine and toluene-2.5-diamine sulfate were used as a hair coloring agent precursers. The degree of dyeability was checked by the change of CIELAB $L^*$ value according to dyeing time. And the damage of hair was evaluated by the tensile strength and morphological change of hair in SEM. When the hair was dyed, the CIELAB $L^*$ value was decreased with dyeing time regardless of the type of precursers. But when the hair was dyed after nutritional treatment, the CIELAB $L^*$ value showed lower level. This means that the nutritional treatment covers the scale of hair and protects the hair from the chemicals.
