  • 지구상에는 약 40만 종의 식물이 존재하는 것으로 알려져 있으며 이 중에 는 질병의 치료를 위한 약재로 이용되거나 나무는 대부분 목재 등으로 이용된다. 향나무(Juniperus chinenesis L.)는 항균성 및 방충성이 뛰어난 상록수로서 목재는 조각재나 가구재로 사용되고 민간 및 한의학에서 다양한 증상의 약재로 쓰이고 있으며 부패한 냄새를 제거할 목적이나 향재 및 향료로도 쓰이고 있다. 열매의 정유성분은 화장품, 술, 캔디 등에 사용되며 cedrol은 향료보류제, 유분은 훈향료, 목부는 고혈압, 곽란, 심복통, 통기파혈에 쓰인다. 향나무는 폴레페놀 성분이 함유되어 있고 피톤치드가 많이 나오는 것으로 알려져 있으며 심재의 폴리페놀 화합물은 항암, 항균, 항알러지, 노화방지 및 심장질환 등을 예방하거나 지연시키는 등 광범위한 약리학적 활성을 나타내어 식품, 의약품, 화장품, 향료등 다양한 분야에 활용되고 있다. 향나무 추출물에 관한 연구로는 성분분석과 생리활성 등에 관한 의약학 분야의 다양한 연구와 항산화, 항균활성 등 약리작용에 연구가 최근 다양하게 이루어지고 있는 것을 볼 수 있다. 측백나무속에 속하는 나무들은 대부분 정유 성분을 함유하고 있는 특성으로 항균성 등 바이오 기능성 소재 개발을 위한 연구가 활발히 진행되고 있으나, 향나무 추출물의 염색성에 관한 연구는 찾아보기 어려운 실정이다. 이에 본 연구에서는 다양한 용매를 이용하여 향나무의 잎, 열매, 수피, 심재 각 부위 추출물을 이용하여 견직물에 대한 염색성을 살펴봄으로써 향나무 추출물을 활용한 천연염색과 염재로서의 가능성을 확인하고자 하였다. 실험 결과 증류수를 염액 용매로 염색한 결과 모든 추출물의 잎, 열매 염색포의 색상은 대부분 옅은 Y계열로 나타났으며 향나무의 수피와 심재 염색포는 대부분 적색기미가 강한 YR계열로 나타났다. 에탄올 혼합액을 염액 용매로 하여 염색한 결과 향나무의 잎과 열매의 색상은 대부분 Y계열의 색상을 나타냈고 유기용매 추출염색포에서 정유성분으로 추정되는 물질 때문에 균염이 어려웠으며 수피와 심재 염색포에서 대부분 R계열의 색상이 뚜렷이 나타났다.

  • This study investigated the color change, enhancement of dye uptake, washing fastness, and light fastness of cotton and silk when dyed with Juniperus chinensis and Terminalia chebula (combination dyeing) using various methods. The dyeing methods were 1) dyeing Juniperus chinensis extract and Terminalia chebula Retzius extract sequentially (J-T), 2) dyeing Terminalia chebula Retzius extract and Juniperus chinensis extract sequentially (T-J), 3) dyeing Juniperus chinensis extract and Terminalia chebula Retzius extract simultaneously (J+T), and 4) dyeing Juniperus chinensis extract 4 times repeatedly and followed by a dyeing Terminalia chebula Retzius extract in sequence. In terms of increased dyeing uptake, combination dyeing (dyeing 2 times like method 1, 2, 3) had the same impact as the repeated dyeing (method 4). The color of J, T combination dyeing showed wide range of mixed YR series, Y series resulting from Terminalia chebula Retzius, and R series resulting from Juniperus chinensis. In cotton, J-T dyeing method showed superior enhancement of dye uptake, and T-J method in silk. In both of the cases, Y series color from Terminalia chebula Retzius extract was mainly shown (Y series color was superior to R series color after dyeing). Therefore, it is recommended for cotton to implement T-J method and for silk to implement J-T method in order to enhance both dyeing uptake and emphasize the color of R series. The K/S value of combination dyed fabrics was decreased by increasing washing time; however, the K/S value of combination dyed fabrics was increased by increasing UV irradiation time. But after repeated washing and longer UV irradiation, ${\Delta}E$ value of combination dyed fabric became smaller compared to fabric dyed with Juniperus chinensis only. Thus, it was found that after J, T combination dyeing, fabric became less prone to fading by washing and UV than after Juniperus chinensis single dyeing was done.

  • The purpose of this study was to investigate the characteristics of the pigment and the dyeability of juniperus chinensis needles, berry, bark and heartwood extracts using distilled water, methanol, normal butanol and ethyl acetate as a solvent. Ultraviolet-visible absorption spectrum bands of the extracts were measured at around 280nm to 320nm in all the solvent extracts. The maximum absorption wavelength was able to determine tannin. All the solvent extracts except for distilled water extracts were able to confirm the presence of chlorophyll. Infrared absorption spectra (FT-IR) of all parts of the extracts showed broad absorption bands of OH due to phenolic-OH, benzene CH peak of phenol chemical structure, ether-based stretching vibration peak and the peak of flavonoid compounds that appeared in all the solvent extracts. The yield of juniper needles and heartwood in distilled water and methanol extraction were effective. Extraction of berry yields in distilled water was also effective. The yield of ethanol extraction from the bark showed better efficiency. As a result of using distilled water for the dye solution, the color of the fabrics dyed with all extracts of the needles and Y series berries generally showed light Y progression with a strong red tinge. By using a mixture of 20% ethanol and 80% distilled water for the dye solution, the color of the fabrics dyed with needles and berry extracts showed Y series dominantly. The color of the fabrics dyed with Bark and heartwood extracts were dominantly R series.

  • This study was carried out to investigate the antifungal activity and house dust mite repellent effect of cotton and silk fabrics dyed with Juniperus chinensis heartwood extracts by hot-water and methanol. The chemical composition of Juniperus chinensis heartwood extracts by hot-water and methanol was analyzed by GC-MS. In the case of antifungal activity, dyed fabrics with hot water extract had no effect against chaetomium globosum fungus. But showing no growth in fabrics dyed with methanol extract, dyed fabrics with methanol extract showed very excellent antifungal activity. Silk fabric dyed with methanol extract showed excellent house dust mite repellent effect of 94.3%~96.0% against dermatophagodes farinae. The composition of Juniperus chinensis heartwood extracts from hot-water and methanol was different. There were no terpene and its analogue peaks in hot-water extract. However there were terpene and its analogue peaks in methanol extract. From these GC-MS results, terpene was identified in methanol extract of Juniperus chinensis heartwood. Efficient ingredient of antifungal activity and house dust mite repellent effect was assumed terpene.

  • In this study, we report dyeing properties and functionality of cotton and silk fabrics dyed with methanol extract from Juniperus chinensis heartwood. Non-aqueous dye of Juniperus chinensis heartwood extracted with methanol was expressed reddish color. It showed relatively good affinity to silk than cotton. Dye uptake of cotton and silk continued to increase according to the increase of the dye concentration. Cotton was not affected by the dyeing temperature and time, however, dye uptake of silk was increased as the dyeing time and temperature were increased. Dye uptake of cotton and silk were the highest at pH 8 and pH 6 respectively. Dyed fabrics showed various colors depending on mordant types and mordant concentration. Washing, light and perspiration fastness were not good. However, rubbing and dry cleaning fastness showed relatively good grade. Dyed fabrics of ultraviolet-cut ability and deodorant ability were improved. Also, dyed fabrics showed very good antimicrobial abilities of 99.9%.

  • The purpose of this study is to investigate dyeing properties and functionality of cotton and silk fabrics dyed with hot-water extract from Juniperus chinensis heartwood. Water-soluble dye of Juniperus chinensis heartwood extracted with distilled water was expressed YR color series. Dye uptake of cotton continued to increase according to the increase of the dye concentration. Its variation trends were shown to be similar to the isothermal absorption curve of the Freundlich. Dye uptake of silk was better than cotton, increased depending on increasing concentration of the dye, dyeing time and temperature. Its variation trends were shown to be similar to the isothermal absorption curve of the Langmuir. As the pH increased, the dye uptake of fabrics reduced and showed increased on red tinge. Colors of the dyed fabrics were various, depending on dye concentration and the mordant type and mordant concentration. Washing fastness, light fastness and perspiration fastness were not good. However, rubbing and dry cleaning fastness showed relatively good grade. Dyed fabrics of ultraviolet-cut ability and deodorant ability were improved. And dyed fabrics showed antimicrobial abilities of 99.9% against Staphylococcus aureus.
