I referred to documents to study the origin and the progressing process of textiles. Cotton seeds were first imported from China by Mun, Ik Jem at the end of the era of Koryeo, and cotton had several different names such as mok-myen, cho-myen, gil-pae, baek-chep-za, tap-po, ban-ki-wha, dong-yep-po and so on. Since the era of the Three Kingdoms, people had heard of cloth of superior quality but it was not certain whether it was imported from China or made in our country. It seems that cotton was not made during that period, white silk, hemp cloth, and ramie fabric were produced. At that time, linen was called cotton by mistake. After importing cotton seeds from China, all the people began to plant them and made their clothes from them. At the beginning of the Yi Dynasty, the weaving technique was dependent on China. However, the government persuaded farmers to plant them. At that time cotton was used as a means of purchasing instead of money. Silkworms raising started during the era of the Three Kingdoms and it was widely spread at the beginning of the Yi Dynasty. In order to encourage sericulture' spinning and weaving instruments were installed in the royal palace and the queen with sher court maids demonstrated how to spin and weave. The activity was named "chin-jam-ye." Linen was the representative of all textiles and it was also very popular. The technique of weaving had already been highly developed at the era of Silla. During the era of the Three Kingdoms people used "bang-chu-cha" as a weaving instrument. They discovered several new hand machines in the period of the Yi Dynasty: they were instrument of removing seeds, spinning wheel, hemp cloth loom and so on, and we find the remains of them these days.

This study examined textiles used for the ancient costumes that are excavated from tombs of the Chosun dynasty, focusing especially on Po(overcoat). The result of the study is that silk occupies 79.8% of all the textiles used for Po, and cotton and linen follow. The weaving method of silk was primarily plain and satin weaves. However the use of twill, gauze, and double weave, that had led weaving methods of silk during the Koryo dynasty, are considerably decreased in Chosun dynasty. Danlyeong(단령) and Cheollik(첩리) had been made of various textile fabrics like cotton, linen, silk and blended fabric before Imjinwaeran(임진왜란). After the war, they were simplified in gauze weaved silk or satin weaved silk, And also patterned fabric were widely used for them than other Po. Simple fabrics like cotton, linen and plain weaved silk had been used for Aekjureum(액주름) and Jiklyeong(직령) before Imjinwaeran. After the war, Jiklyeong was used as underwears of Danlyeong, so it was made of high quality patterned silk. Dopo(도포) and Changuiryu(창의류) were mainly excavated from tombs after the war, high quality plain weaved silk are used than gorgeous Patterned silk. For the Dopho(답호) and Bansuui(반수의), before the war, they were made with various textiles such as plain weaved silk, twill weaved silk, satin weaved silk, cotton, linen, and blended fabric. But after the war plain weave was mainly used. In Jangui(장의), since it was mostly for women, many kinds of women's patterned silk were used in than any other Po. There were only a few excavation of Simui(심의) and most of them were made of ramie and were hemmed in black satin without pattern.

The purpose of this study was to increase the ultraviolet-light (UV)-cut ability of cellulose fabrics (cotton, ramie, and rayon) dyed with safflower yellow colorants. For this purpose, samples treated with UV-cut agent and tannic-acid were compared with the untreated samples after UV exposure in terms of K/S value, color changes(${\Delta}E$), SEM, and strength retention. The K/S value rapidly decreased after 28 days exposure, whereas the K/S value of the samples treated with both UV-cut agent and tannic-acid decreased to less than that of the untreated samples. In color changes, $L^*$ increased while $a^*$ and $b^*$ decreased, indicating less red and yellow character in color. This induced a change in the hue, value and chroma values. However the color change(${\Delta}E$) of the samples treated with both UV-cut agent and tannic-acid was less than that of the untreated samples. Scanning electron microscopy (SEM) pictures showed a severe degradation by exposure in all samples. Tensile strength rapidly decreased after 28 days for cotton and rayon, and after 21 days for ramie. However, the strength retention of the samples treated with UV-cut agent and tannic-acid was higher than that of the untreated samples.

Taegwondo uniforms need powerful durability in fabrics against friction and shock because of higher exercising power. Therefore, in this study we developed more comfortable Taegwondo uniform for functional fabrics(deodorization rate, antibacterial activity and static charge). Chitosan is a deacetylated product of chitin, has widely been used in the biomedical sector, food industry, and textile industry. For the purpose of this study, we used the chitosan, which was congenial to the human body. Then, we compared the differences between the chitosan treated fabrics and non treated fabrics of Taegwondo uniform(100% polyester, 65% polyester/35% cotton). Chitosan was dissolved in 1% acetic acid. Also, the fabrics were washed using distilled water. Afterward, its treatment with chitosan was completed by padding the sample to its wet pick-up at $80{\pm}5%$ and by heating $150^{\circ}$ for 3 minutes. The chitosan treated Taegwondo uniform was improved on deodorization rate than non treated uniform. And the chitosan treated Taegwondo uniform was improved remarkably the antibacterial activity in all samples. In the further researches, the static charge was reduced in chitosan treatment uniform.

Collections in the buddhist statue owned by Dr. Jong-Hm Baik(白宗欽) included 3 ancient documents and 2 wooden cylinders that showed a clear historical order. The temple and buddhist statue that these objects were belonged to were not known, however, according to the document, it could be inferred as Chunsukwaneumsang(천수관음상) created in 1322 and reformed in 1614 from the list of donator for the statue. Inside a wooden cylinder, a bundle of ivory, yellow, green, orange, and dark brown fabrics that were folded up and tided up with 5 different colored thread strands and aromatic trees and rice plant was placed on the bottom. All the fabrics were silk. Three thread strands were silk. The white and blue strands were cotton fibers as a result of analysis of IR spectrum and the microscope. According to a radioactive carbon isotope dating by accelerator mass spectroscopy, years before present was 160$\pm$40, and cablibrated ages were 1680-1890 (79.3$\%$), 1910-1960(16.1$\%$) in 95.4$\%$ probability. Accordingly, the fabrics in the buddhist statue proved to be reformed in 1614 not the original ones in 1322.

The effect of Sunlight exposure on reducing the microorganism counts in the bedding materials was experimented by using 3 kinds of microorganisms(S. aureus, K. pnenmoniae and E. coli) and 3 kinds of fabrics (cotton, silk and polyester). Counts of the microorganism were examined before and after sunlight exposure. The sunlights were controlled U.V and Daylight D50 using MacBeth artificial light source. The specimens were exposed for 5 min, 10 min and 30 minutes under the $20^{\circ}C$ and 60% R.H, distance is 50cm from the light source. Results were as follows, 1. The reduction rate of the 3kinds of microorganisms was remarkably great under the U.V exposure. The U.V. exposure was very effective way to sterlize the bedding materials in the house care. 2. S. aureus was the most susceptible to U.V. exposure and the sunlight exposure. E. coli was the most resistant to the U.V and the sunlight exposure. 3. The reduction rate of the 3 kinds of fabrics was not significantly different. The polyester is more resistant than the silk and the cotton. Those were shown good reduction rate if all kinds of microorganism under the U.V and daylight.

국내에서 자라는 지의류의 한 종류인 Parmotrema austrosinence를 채취하여 염액을 제조하고, 제조된 염액을 사용하여 견직물, 나일론직물과 면직물을 염색하였다. Parmotrema austrosinence를 암모니아수에 넣고 발효시켜 얻은 염액을 사용하여 pH를 4, 7, 10으로, 염색온도를 $30^{\circ}C$, 50^{\circ}C$, $80^{\circ}C$로 각각 조절한 후 염색을 하였다. 면직물은 견직물과 나일론직물에 비해 염색성이 낮게 나타났다. 면직물의 염색성 향상을 위해 키토산 액으로 처리하고 염색성과 염색견뢰도의 변화를 검토하였다. 염색된 시료들의 염색성은 K/S값, ${\Delta}E$와 Munsell값을 측정하여 평가하였다. 염색된 시료들의 K/S값은 견직물의 경우에는 520nm에서, 나일론직물과 면직물은 480nm에서 최대 흡광파장을 나타냈다. 견직물 염색포의 K/S값은 $4.6{\sim}9.3$으로 $1.0{\sim}2.7$인 나일론직물이나 $0.8{\sim}1.6$인 면직물에 비해 매우 높게 나타나 견직물이 Parmotrema austrosinence 염액에 대해 우수한 염색성을 가짐을 확인하였다. 염색온도가 높아질수록 먼셀 색상값이 red나 yellow red에서 yellow쪽으로 이동하는 색상변화가 나타났다. 견직물의 경우, 염색온도가 $50^{\circ}C$와 $80^{\circ}C$일 때의 염색성이 비슷하였으며, 다른 직물의 경우에는 염색온도 상승에 따라 K/S값도 높아졌다. 따라서 지의류를 사용한 적정 염색온도는 견직물의 경우 $50^{\circ}C$, 다른 직물의 경우 $80^{\circ}C$임을 확인하였다. 염색된 시료의 먼셀 색상은 견직물에서는 R(red) 영역에서, 나일론 직물에서는 YR(yellow red)-R 영역에서, 면직물은 YR 영역으로 나타났다. 면직물과 나일론직물은 중성 또는 산성염액에서 염색이 잘 되었고, 견직물의 경우는 중성 염액에서의 염색성이 가장 우수하였다. 염색성이 낮게 나타난 면직물은 키토산 가공에 의해 염색성과 염색견뢰도를 향상시킬 수 있음을 확인하였다 염색된 시료들의 일광견뢰도와 세탁견뢰도는 대체로 낮게 나타났으나 드라이크리닝 견뢰도는 4-5급 또는 5급으로 모두 우수하였다.

As UV radiation to the earth increased over recent years, many adverse effects of UV radiation have been reported. There are needs to develop UV-protective apparel and accessaries to protect skin from these harmful effects. Cellulose is one of the most frequently worn fiber during summer time. However, celllulose shows very low UV-protective property especially in case of thin and low fabric content. In this study, UV-protective cellulose textiles were developed using chiotsan mordanting and green tea dyeing. The repetition effect of chitosan and green tea treatment were focused. Three different cellulose fibers, cotton, linen, and ramie, were used for this study. All chitosan mordanted and green tea dyed fabrics showed increases in UV-protective property. The color of fabrics tended to darker as the numbers of mordanting process and green tea dyeing increased. UV-protective property did not increase significantly upon the repetition of mordanting and green tea dyeing treatment except ramie fabric. UV protective property was persisted upon washfastness test in all three cellulose fiber types.

Kenaf was cultivated and harvested in large quantity in Cheju Island and Chinju, Kyungsangnamdo. It was chemically rotted with 3% NaOH for 60 minutes at 100$^{\circ}C$, neutralized using 1% acetic acid, washed and dried, and obtained 40kg of dry kenaf fiber. Kenaf 15/rayon 85, flax 15/rayon 85, and rayon 100% yam was spun and the physical characteristics were measured. Plain weave and twill weave fabrics were made using each of the above yarns as the filling yam. Cotton 100% yam was used as the warp yam in all fabrics. Kenaf/rayon blend yarns were higher in tenacity and elongation, lower in yam uniformity, higher in the number of nep than the flax/rayon blended yams. Kenaf/rayon blend fabric had higher tenacity and elongation compared to the flax/rayon blend fabric Kenaf/rayon blend fabric was most stiff in both plain weave and twill weave fabrics whereas drape characteristics was dependent upon the fabric structure of the kenaf/rayon blend and flax/rayon blend. There were little differences between the kenaf/rayon blend fabric and the flax/rayon blend fabric in the Kawabata physical measurements and the PHVs. The only drawback of kenaf fiber was it's surface roughness and it is expected that it can be improved by enzyme retting and mechanical bundle separation.
