In this research, the curly dock was used in the process of dyeing for fabrics of the inner wear & the patient wear. Since the curly dock has a pharmacological effect on dermatosis, this study focused on the variety of color and functions of the inner wear fabrics & patient wear fabrics to make the best use of the pharmacological effect of curly dock. With regards to giving a variety of colors and functions in the inner wear, patient wear fabrics, the curly dock dye was used in each treatment conditions on the cotton & silk fabrics. After dyeing, the dyeability, color change, light fastness, washing fastness, perspiration fastness, antibiosis, far infrared emissivity and emission power were evaluated. The evaluation results are as follows; The dyeablity increased from repeated dyeing and, by using the mordant, variety of colors such as skin, mustard, greyish-brown and dark earth colors were conformed to the naked eye. Fe mordant was better than Al on the lightfastness and the washing fastness. The repeated dyeing was found out to have less effect on neither lightfastness nor washing fastness. Both silk and cotton fabrics were graded $3{\sim}4$, since their degree of degradation appeared to be the same in alkali perspiration and acidic perspiration. In the case of silk fabrics mordanted by Al, the rate of declining in both Staphylococcus aureus ATCC 6538 and Klebsiella pneumonia ATCC 4352 were 99.9%. In addition, the antibiosis was enhanced when the mordant was used. The far infrared was 86.6% of emissivity, $3.34{\times}10^2\;W/m^2{\cdot}{\mu}m$ emission power.

Mixed A, Chlorella vulgaris, Nannochloropsis oculata, Chaetoceros calcitrans 등 4종류의 미세조류로부터 99.9% 에탄올로 추출한 성분의 항균활성을 검증하기 위해 그람음성세균 2종(E. coli, S. Typhimurium)과 그람양성세균 2종(S. aureus, B. cereus)에 대하여 paper disk diffusion assay, MIC, MBC를 측정하였다. 4종류의 미세조류 추출물은 공시균주에 대하여 0.62-1.66 mg/mL의 MIC를 나타내었으며, C. vulgaris 추출물이 4종의 공시균주에 대한 MIC가 0.62 mg/mL로 가장 강한 항균활성을 나타내었으며, MBC 또한 C. vulgaris 에탄올 추출물이 E. coli에 대해 2.50 mg/mL, S. aureus, B. cereus와 S. Typhimurium에 대해서는 4.16-5.00 mg/mL로 가장 강한 항균활성을 나타내었다. 항균활성이 가장 강한 C. vulgaris 에탄올 추출물의 성분을 분석한 결과, 함량이 가장 많은 성분은 9,12-octadecadienoic acid (linoelaidic acid, peak 5, 7)로 38.8%이었으며, 그 다음이 2-Hexadecen-1-o1, 3,7,11,15-tetramethyl (phytol, peak 2,6)로 30.0%이었다. Octadecadienoic acid는 일명 linoelaidic acid로 탄소수 18개의 고도불포화지방산이며, 두 번째로 함량이 많은 Phytol은 클로로필을 구성하는 불포화 제1급 알코올의 일종으로서(엽록소의 구성 성분) 병원성 대장균 및 황색포도상구균에 항균활성을 나타낸다는 보고로 볼 때, 이 2가지 성분이 항균활성의 주성분인 것으로 사료된다.
