In several literature in China were recorded various species of the indigo genus, but in Chosen documents, the two have been intensively mentioned, that is, Polygonum tinctorium (PT) and liatis Tinctuna(IT). Allowing for some slight contradictions of the records between the two countries, we insist that J)T is the aborigines historically longer than any other indigo plant in Korea and that IT is the one Implanted from China in late Chosen period. Indigos can be grouped into two major categories : 'Chon' or Indigo forming sediment in the course of making, and 'Nam' or the one without. The dyestuffs of blue, or dark blue tineged with red, which had been ocasionally recorded until the mid Chosen, could be made from the . species without sediment. The period when the color thus obtained was prevalent can be traced back to the era of Yongio, when the import of blue-dyed textiles from China was prohibited to encourage the domestic dyeing industry. However, a more clarification is needed on this matter, since all of the previous researches are arguing, with little validity, that the indigo genus in Korea be PT. Judging from the documents recording that PT did not form any sediment, and that from it was obtained only light color like indigo, it is a matter of re-discussion in terms of botanical taxonomy to define as PT the species being cultivated in some areas in Chollanam-do. In conclusion, a joint research, including specialists in traditional dyestuffs and in botany in relation to the taxonomical problem of the indigo genus, would be expected for further Investigation on this matter.

Natural indigo dye was prepared by extracting from Polygonum tintorium, precipitating with calcium hydroxide, and dried. Dyeing was carried out using sodium hydrosulfite as a reducing agent for the prepared natural indigo powder. K/S value, color property, and colorfastness of dyed fabrics were investigated. Optimum dyeing conditions obtained were 60$^{\circ}C$, 20min. Regardless of indigo dye and sodium hydrosulfite concentration, Munsell hue of dyed fabrics was PB color. Compared to the dyed fabric with both sodium hydroxide and sodium hydrosulfite, those with sodium hydrosulfite only showed higher color strength(K/S value). Colorfastness of dyed fabrics showed high rating except of wash/dry cleaning fastness of silk fabrics dyed low color strength.

쪽잎 300g를 2.5l물에 색소를 울어 내기 위하여 사용한 초산 및 황산은 제조량에는 차이는 없었으며, 공기 공급의 경우도 30분 이후에는 큰 차이가 없었다. 쪽잎 300g에 초산(5 ml/2.5l과 암모니아수(10ml/2.5l)을 넣는 경우, 염료생산량은 1.631 g으로 가장 높았다. 전통염료와 개선 (순수) 쪽 색소 제조 방법으로 제조한 쪽이 성분과 분자량이 같은 수준 이었다. 순수 색소의 제조 쪽은 전통 염색 보다 소취성이 높았고, 정균감소율은 황색포상구균과 폐렴균이 26.3%와 19.1%이었다.

본 논문에서는 쪽의 발효염색이 잿물과 같이 강 알칼리 매체 하에서 사용해야 하고 또한 자연 발효의 경우 온도조절이 제한되어 있어 단백질 섬유 특히 양모에는 적합하지가 않은 점 등을 해결하기 위해 우리나라에서 주로 현재 재배되고 있는 polygonum tinctorium을 사용하여 Saxon blue 법으로 단백질 섬유를 염색하여 염색성을 살펴보았다. 그 결과 Saxon blue로 염색할 때의 등온흡착곡선은 Langmiur형임을 보였으며 색상은 주로 B 영역에서 나타났다. Saxon Blue로 염색한 견 직물과 양모 직물 모두 우수한 항균성을 나타내었으며 드라이 크리닝과 마찰에 대해서는 좋은 견뢰도를 보여 주었다.

The purpose of this study is to enhance the usability of hanji fabrics by expanding the color space of hanji fabrics. For the expression of various colors of hanji fabrics, single and combination dyeing were carried out using natural indigo(Niram, Polygonum tinctorium), marigold extract colorant, and madder extract colorant for three types of hanji fabrics with different fiber compositions(hanji, hanji/cotton, hanji/silk). The light, medium, and deep colors obtained through individual single dyeing were shown to be PB Munsell colors in the case of indigo dyeing, Y color for marigold dyeing, and R color for madder dyeing. For combination dyeing, indigo dyeing was first carried out under the conditions for light, medium, and deep colors, respectively, and marigold or madder dyeing was performed thereafter. Indigo and marigold combination dyeing produced PB, B, BG, G, and GY Munsell colors and indigo and madder combination dyeing produced PB, P, RP, and R Munsell colors. Overall, the color change of hanji/silk fabric was more diverse than that of hanji fabric and hanji/cotton fabric. In the indigo, marigold, and madder combination dyeing into individual deep colors, blackish PB and P Munsell colors was obtained. Colorfastness to washing, dry cleaning, rubbing, and light were relatively good with above rating 4. Finally, 9 colors excluding YR color out of 10 Munsell color were obtained. We confirmed that the expansion of the color space of Hanji fabrics by the single and combination dyeing with indigo, marigold, and madder.

쪽풀 생잎에서 우려낸 색소 액에 소석회를 첨가한 후 쪽풀 색소의 침전물을 만들어서 냉동 건조시켜 쪽풀 색소를 제조하여, 그 성분을 조사한 결과 다음과 같은 결론을 얻었다. 1. UV분광광도, TLC 정성 분석, HPLC 측정 결과 쪽 분말 용액의 2개 bend가 나타났으며, 적색색소대인 540nm 와 청색 색소대인 620nm가 존재함을 알 수 있었다. 2. FT-IR 분석으로부터 $1627cm^{-1}$에서 채, $3200{\sim}3300cm^{-1}$에서 NH의 흡수대가 나타나고, 적색 및 청색 색소의 IR spectrum이 일치하였으며, 3. EI-mass 분석 결과 청색과 적색 색소의 fragment 이온의 m/z가 일치하고, $^1H_MNR$ 분석결과로부터 두 색소는 이성질체임을 알 수 있었고, 4. 쪽 염료 성분 함량을 조사한 결과 인디고 색소 4.06%와 인디루빈 1.06%이었다.

생쪽잎을 다양한 방법으로 건조, 분말화하여 염색하는 경우 전통적인 색소추출방법에서 얻을 수 있는 색상으로 염색됨을 확인하였다. 특히 급냉/동결건조한 분말은 생즙법의 염색효과에, 상온건조한 분말은 생즙법과 침전법의 염색효과에 더 효율적인 방법으로 나타났다.

In Korea, to deal with the housing needs of the elderly, the government operates free nursing homes and residential homes. And to deal with the needs for daily necessities, imported products or products for the disabled have been supplied for the elderly. The government has recognized the importance of silver industry in this rapidly aging society and has established strategies to vitalize industries related to seniors to deal with the seniors' need for food, clothing, and shelter. This study examined the necessity of nursing home gowns, and the development of nursing home gowns that are environmentally friendly, beautiful and functional for the new silver generation. For this study, literature review and Internet search were conducted regarding the status of silver fashion, necessity of nursing home gowns, emergence of new silver generation and change in lifestyle, and value and utilization of natural dye and traditional patterns. To produce nursing home gowns, fabric was dyed using fermented indigo dying, and 3 styles of nursing home gowns for each gender were designed in consideration of seasons. Lastly, these gowns were evaluated by fashion experts, medical personnel, hospital gown and silver wear experts, and natural dye experts. The results showed that the traditional Korean designs developed in this study were excellent and the fermented indigo dye was appropriate for the nursing home gowns. The development of nursing home gowns in this study will be utilized as basic material for the development of silver wear and nursing home gowns to improve the quality of life for the seniors.
