To set up the outstanding and scientific dyeing method in making the condensed liquid of pigment obtained from onion skins and the improved reliability, the following basic experiments were performed. The pigment was extracted in the distilled water at $70^{\circ}C$ and methanol at room temperature and then it was analyzed with LC/MS/MS system (Liquid Chomatography/Mass Spectroscopy/Mass Spectroscophy, LIQ Advantage Max, Thermo Finnigan, USA) for its pigmental characteristics. The unrefined silk and refined silk were dyed by making use of the derived pigment in such a way. The chromameter (CR-200, Minolta, Japan) was used to measure the change in surface color in textiles to be dyed by the extracting condition and the color difference ${\Delta}E$ was determined according to the color difference formula CIE LAB through measuring the psychometric lightness L* and chromaticity coordinates a* and b*.

This treatise was carried out to study the hereditary phenomenon of silk lousiness and the interaction of genes related with silk lousiness. It was also studied how to improve the silk lousiness of general raw silk by refining process because the selective process was found as unsatisfactory method. The conclusions reached were as follows. A. Conclusions related with genetic problem. 1. The decreased effects of the lousiness were 11 % in the F$_1$ hybrids. 2. Lousiness was considered to inherit as the incomplete dominance. 3. The effects of the lousiness gene were additive, and the lousiness of raw silk might be influenced by more than two genes. 4. The quantitative characters of cocoons were not genetically correlated with the occurrence of lousiness. 5. Lousiness could not be said to occur more in the heavy-cocoon strains. 6. The microscopic lousiness test of this paper showed the same result of the international exforiation test. B. Conclusions related with lousiness improvement. 1. Raw silk was able to be refined by the employment of 0.2% cationic softener solution for 30 minutes at 95$^{\circ}C$, supressing the occurrence of lousiness. 2. Anionic chemical softener was not available for silk refining process. 3. The above cationic softener refining prosess did not cause any physical defect for the silk fiber. 4. Soap refining process caused silk lousiness easily.

Artificial silk that called "Ponggi (Gyeongsangbukdo, Korea) In-Gyeun" in Korea is entirely viscose rayon of which made main component refined larches and cotton linter. It also is natural fabrics with light weight, cool texture, free from the body and well ventilation property, so, feel good touch during the wearing. In addition, it often used as summer cloth and bedding because it has good absorbancy to perspiration and antistatic. The "Hanji", made of paper mulberry, is known as useful material for human. In this research focused on dyeability of Artificial silk/paper mulberry mixed fabrics using Dendropanax morbifera Lev.(called as "Hwangchil") Especially, the results were in comparison to the dyeing properties of Hwangchil with liquid/solid fermentation or not. As the results, The ${\Delta}E$ difference was dominated when the fabric dyed with fermentation by solid state at $60^{\circ}C$. And it was confirmed that the pH of fermented dye had an important influence in the coloration.

This research confirmed the chemical structure of Curcumine and Carthamin pigments whose pigments were separated and refined from the Curcuma longa and Carthamus Tinctorious which were natural dye using FT-IR, HPLC and so on. The cotton and the silk fabrics were dyed using a main pigment and then this research obtained the conclusion as it follows. The curcumine, the main pigment of Curcuma longa extracted from the mixed solvent of acetic anhydride and methanol ($CH_3OH$), had the maximum absorption wavelength at 504.0 nm and was confirmed as yellow natural pigment. The Carthamin, the main pigment of Carthamus Tinctorious extracted from the mixed solvent of dichloromethane and methanol, had the maximum absorption wavelength at 420.0nm. This pigment was confirmed as yellow natural pigment. The dyeing property of the main pigment about the silk fabrics was superior to that about the cotton in both the Curcuma longa and Carthamus Tinctorious, and the dyeing property of Carthamus Tinctorious was superior to that of Curcuma longa.

Effect of the pH condition was examined on extraction and dyeing of the yellow and red dyes of safflower. Absorption of dye solution extracted from safflower was changed by pH of solvent. In the case of yellow dyes, cotton and ramie weren't dyed regardless of pH of dye bath, but silks were significantly dyed at pH4. Raw silk showed better dyeability than refined silk. In the case of red dyes, cotton and ramie absorbed red dyes selectively, but silks absorbed yellow dyes more significantly than red dyes. Efficiency of extraction and dyeing of yellow dyes in acidic range were find out higher than that in neutral range. Red dyes was effectively extracted at pH11 and dyed at pH6.

The aims of this study are to elucidate the relationship between the luxurious trends of costumes and the importation of Ming's patterned textiles in the $17^{th}$ century, and to analyze the similarity between certain Joseon and Ming fabric patterns. After Imjinwaeran[임진왜란] and Byungjahoran[병자호란], more diverse Joseon textile patterns appeared. Generally, wars lead to a shortage of luxury goods and basic commodities. However, $17^{th}$ century Joseon had an abundance of luxury goods, which allowed even some commoners to have clothing made of Chinese silk. That was the result of free trade between the Koreans and the Chinese merchants in Joseon. Ming's merchants followed the Ming's troops into the Korean Peninsula and targeted Koreans to sell their goods, such as fur coats and fur hats. Free trade between Ming and Joseon took place at Junggang [중강] and Donggangjin [동강진]. Joseon imported Chinese textiles there and resold them to Japanese merchants. Some of the Changgi Chung's excavated fabrics might be an evidence of the import from the Ming. These fabrics had the inscription and were similar to Ming fabrics. It can be assumed that trade occurred between Joseon, China, and Japan, as fabrics found in the countries had similar patterns such as flower, bee, and four seasons, which represented longevity. Furthermore, Chinese fabrics might have triggered Joseon's weaving skills to develop, which led to the ability to weave refined and beautiful brocade satin at Sangbang [상방]. According to Uigwe[의궤], Sangbang could weave silk fabrics in the 1620s and 1630s. The improvement of weaving techniques might make it possible to weave some popular patterns at Sangbang.
