This study examines the effects of Evening primrose on colors, color fastness, and the antimicrobial activity of dyed fabrics. The results are as follows. The dyeing conditions of Evening primrose on cotton and mercerized cotton were optimized at $50^{\circ}C$, 60 minutes, and 200% (o.w.f.). In addition, Evening primrose dyeing on silk was determined at $90^{\circ}C$, 60 minutes and 200% (o.w.f.). The pre-mordant concentration of chemicals of cotton, mercerized cotton and silk was optimized at 1% (o.w.f.). The post-mordant concentration on mercerized cotton, silk and cotton was determined at 1% (o.w.f.) and 3% (o.w.f.), respectively. The mordant methods (such as pre-mordant and post-mordant) were slightly affected on the hue of dye-fabrics. Wet cleaning fastness of cotton was improved by post-mordant; otherwise, the wet cleaning fastness of mercerized cotton and silk was improved by a pre-mordant. The dry cleaning fastness of cotton and silk was excellent regardless of mordant methods. The dry cleaning fastness of mercerized cotton was improved by a post-mordant compared to a pre-mordant. The antimicrobial activity of Evening primrose-dyed fabrics was shown at 99.9%. The excellent antimicrobial activity of dyed fabrics remained after the mordant as well as wet and dry cleaning.

The study that has been conducted is the consideration of the durability of dye, antibacterial activity, and deodorizing effects of cotton and silk textiles dyed with a botanical dying material that has been used in various ways over the years as Korean diet and folk remedies, the pomegranate. 1. The results of the K/S value of dying according to the types of mordants of textiles dyed with pomegranate extract the following have been discovered: The increase of K/S value of dying of the silk textiles appear to be higher than that of the cotton textiles. Next, silk textiles that have been treated with FeSO$_4$.7$H_2O$ appear to be at the highest. 2. The results of the color change measurement show a difference of color can be noticed according to the types of mordant. As opposed to those textiles that had been only scured textiles, all of the dyed textiles appeared to turn yellow. 3. Textiles that had been treated with $K_2$Cr$_2$O(sub)7 recorded the highest durability according to the colorfastness to light results. In the case of the cotton textiles colorfastness to washing, all appeared to show exceptional results of 3rd class or higher, excluding the textiles that had been treated FeSO$_4$.7$H_2O$. However silk textiles recorded relatively low classes of below 3rd to 4th class. For the colorfastness to washing of pollution, the results for both the cotton and silk textiles were excellent at class 4-5. The results of colorfastness to perspiration, colorfastness to rubbing, and colorfastness to dry cleaning showed comparatively exceptional results of 3rd to 4th class or higher when it came to dyed textiles. 4. According to the measurements of antibiosis, dyed textiles that had been treated with SnCl$_2$.2$H_2O$ appeared to show an exceptional bacterium decrease of approximately 70%. 5. According to the deodorizing measurements, dyed silk textiles appeared to have a higher deodorizing effect than cotton textiles. As for cotton textiles, those that had been treated with FeSO$_4$.7$H_2O$ and in the case of dyed silk textiles those that had been treated SnCl$_2$.2$H_2O$ recorded the highest deodorizing effect.

본 연구는 출토직물의 염료 성분 판정을 위한 장기적인 프로젝트의 일환으로서 천연염료 식물 중 우리나라는 물론 동서양 각지에서 과거에 염색식물로 널리 사용되었던 소목에 대하여 주 색소성분인 브라질린을 가스크로마토그라피 질량분석법(GC-MS)으로 검출할 수 있는 최적의 염료 추출 및 분석 조건을 확립하는데 그 목적을 두었다. 소목추출액에 대한 GC-MS 분석 결과 증류수보다는 메탄올이, 메탄올보다는 아세톤 추출이 브라질린 추출효과가 높았다. 추출기기 간에는 $30^{\circ}C$로 진행된 waterbath shaker보다 상온에서 진행된 shaking plate가 브라질린 추출이 높았으며 두 기계 모두 1시간보다는 12시간 추출이 월등히 높은 추출량을 보였다. 증류수를 사용해 pH $3{\sim}9$로 조절하여 브라질린의 추출효과를 조사한 결과 pH 5 조건에서 브라질린 검출량이 가장 많았다. GC-MS 분석 조건은 컬럼내 온도를 초기온도 $50^{\circ}C로 하고 온도 증가율을 $23^{\circ}C/min$로 하여 $210^{\circ}C$까지 끌어올리고 다시 온도증가율을 $30^{\circ}C/min$로 하여 최종적으로 $305^{\circ}C로 가열한 후 14분 동안 holding하여 전체 분리시간을 24.12분으로 한 방법이 가장 효과적이었으며 MSD 스캔범위는 $75{\sim}400m/z$이 적합하였다.

일회용 위생용품의 탑시트로 사용되는 폴리프로필렌 부직포에 천연고분자이며, 인체친화력이 우수한 키토산을 분자량과 농도를 변화시켜 처리하므로써 기능성 개질화된 부직포의 항균성을 비교하고, 소취성과 공기투과도 및 흡습성, 흡수량 등의 수분 특성을 살펴보았다. 키토산의 처리농도가 증가하고, 고분자량일수록 부착률이 컸으며, 저분자량 키토산 처리포의 경우 겉보기 염착량에 의한 염색성이 더 좋게 나타났다. 수분 특성의 경우, 고분자량의 키토산 처리시 동적흡수율과 흡수량이 더 증가하였다. 키토산 처리로 공기투과도는 모두 향상되었으며, 키토산 처리농도가 증가하고 시간이 경과함에 따라 소취율이 증가하였고, 저분자량의 키토산 처리시 소취효과가 더 우수하였다. 박테리아 균주의 종류와 키토산의 농도에 상관없이 고분자량의 키토산 처리시 항균성이 아주 우수하여 위생용 부직포의 성능 중 가장 중요한 항균성과 수분 특성의 기능성 향상을 위해서는 비교적 분자량이 큰 키토산이 효과적이었다.

Recently the interest in natural dyeing has been increased because of the color clarity, natural grace and reactionism in fashion. Indigo dyeing, safflower dyeing and Gal-ott in Cheju-Do become generally known, so the study about the natural dyeing is continued with national intrust and support. In this study, 1 used artemisia for various dyeing tests because we can get it easily. 1 tested the dyeability in wool as well as cotton and silk with wormwood in natural dyeing material. I also dyed nylon with the same material for the comparison of the molecular structure. The mercerization and the chitosan treatment were done in cotton to improve the low dyeability in the natural dyeing. The result of this study are as follows; We have to dye repeatedly to get deep color in natural dyeing, and mordant treatment brought good result in color difference and dyeing fastness. 1. Compared with silk, wool and nylon, the dyeability of cotton was the worse. The color difference of cotton was 18.81 without mordants , and 24.05 with mordant. The dyeability of cotton was much increased by mordants such as potassiumdichromate, copper sulfate, iron sulfate and salt water. The color of cotton was turned into yellow-green in potassium dichromate and yellow-green with deep green in copper sulfate. The mercerization and the chitosan treatment of cotton made the improvement in color, dyeability, laundering fastness, abrasion fastness. 2. The color difference of silk was 3 times as high as cotton. It showed the similar degree with the chitosan treated-cotton. That is to say, silk had good dyeability because it contains amino group and carboxyl group. The dyebility of silk was increased by a mordant such as iron sulfate, potassium dichromate and salt water, Drycleaning fastness showed 5 grade, abrasion-fastness was high over 4~5 grade and sunlight fastness showed 1 grade in all case. 3. The color difference of wool was the best among four fabrics because of 18 kinds of amino acids. It is considered that the sulfate of wool has the polarity and help metal- mordants get the better dyeability such as potassium dichromate, iron sulfate, copper sulfate, and aluminum chloride. The color was reddish-green in potassium dichromate, yellow.greenin iron sulfate and copper sulfate, and yellow in the rest mordants. Drycleaning fastness of wool showed over 4~5 grade, abrasion fastness 5 grade. Sunlight-fastness 1 grade. 4. The dyeability of nylon was almost same because of the similar molecular structure with silk. The clarity of color was poor. The color was yellow-green in copper sulfate and yellow in the rest mordants. Laundering fastness and abrasion-fastness of nylon was good. Sunlight- fastness represented 1 grade.

최근 국내 농촌진흥청 국립농업과학원 연구팀에서 농가보급품종인 백옥잠(잠123 ${\times}$ 잠124)을 이용하여 피브로인 중쇄 유전자 내에 녹색형광유전자(EGFP)를 도입하여 녹색형광 누에고치를 생산하는 형질전환누에 개발에 성공한 바 있다. 그리고 녹색형광 누에고치는 견사의 주성분인 fibroin heavy chain 유전자에 삽입된 형광유전자의 발현으로 정련을 해도 형광단백질의 고유한 색깔이 그대로 유지되며, 자연광 하에서도 도입 형광유전자 고유의 형광색을 나타낸다. 그러나 형광누에고치는 기존의 $100^{\circ}C$ 내외의 고온 처리에 의한 건조, 자견 및 조사 방법을 이용하면 형광단백질에 심각한 변성이 초래되고 이로 인해 형광색깔을 잃게 되는 단점을 가지고 있다. 따라서 본 연구에서는 녹색형광 누에고치로부터 녹색형광단백질의 변성을 초래하지 않는 누에고치의 저온건조 방법, 저온 진공 감압 처리에 의해 고치 내강 내 침지액 침투방법 및 조사방법을 개발하여, 녹색형광 누에고치로부터 천연의 녹색형광색을 띄는 생사를 생산하였다. 그리고 이들 생산된 녹색형광 생사는 별도의 염색처리 없이 패션의류, 벽지, 조명등갓, 액세서리, 인테리어용품 등의 고부가가치 실크소재로 적용이 기대된다.
