The purpose of this study was to evaluate the color image of the natural-dyed silk fabrics. The dye was extracted from pine needle by boiling pine needle with ethanol at $78^{\circ}C$ for 3hours and distilled water at $100^{\circ}C$ for 2hours. The 100% silk fabric was dyed of extract in pH 5 at $90-100^{\circ}C$ for 1 hr. As mordants used were compounds of Al, Sn, Fe, and Cr, color image of pine-needle dyed silk fabrics was classified into 5 factors (pure, gentle, sophisticate, comfortable, pastorale) and the factor pure is most important one of those. Most cheerful image in pure factor was from the fabrics dyed with ethanol extract and then, none and Cr mordanting. Dignified image was from the fabrics dyed with ethanol extract and then, Cu or Fe mordanting. In production, products dyed with ethanol extracts was preferred to those dyed with distilled water extracts. Color image and preference of the silk fabrics dyed with pine needles extracted was affected by extraction solvents and mordants.

한국산 솔잎을 가압.압착하여 얻은 수액을 증류한 솔잎 수액 증류액의 각종 암세포주에 대한 in uitro 세포독성을 시료액 대비 10배, 20배, 40배 희석군과 대조군에 대해 XTT법으로 실험한 결과, 쥐 백혈병 세포주인 L1210에 대해서는 76~89%, 쥐 육종암세포인 sarcoma 180에 대해서는 61~90%의 세포성장 억제효과를 나타내었다. 또한 인체의 monocyte-like cancer cell인 U937에 대해서는 56~81%, 인체 유방암 세포주인 T47D와 MDA-MB-231에서는 각기 12%, 또 다른 유방암 세포주인 MH7A에서는 64%, 인체 간암 세포주인 SNU-354에 대해서는 72%의 높은 세포 증식 억제효과를 나타내었다. 이로써 본 연구 시료인 솔잎 수액 증류액은 쥐 백혈병 세포주인 L1210, 쥐 육종암세포인 sarcoma 180, 인체 monocyte-like cancer cell인 U937, 인체 유방암 세포주인 MH7A, 인체 간암 세포주인 SNU-354에 대해 강한 세포독성을 갖는 것을 알 수 있었다. 이와 함께 솔잎 수액 증류액의 암세포에 대한 독성효과는 솔잎의 처리과정에 따라 다를 수 있으며, 또한 동일한 솔잎 수액증류액의 농도에서도 암세포주 종류에 따라 세포독성정도가 다름을 알 수 있었다. 따라서 최적 투여 농도와 적용 암세포주를 찾을 경우 새로운 항암제로 개발될 수 있음을 제시하였다.

In this study, a dye bath was made using a mixture of distilled water, pine needle extract and bamboo vinegar. Analysis and comparison of various functions of cotton fabrics dyed using bamboo charcoal and gardenia seeds in distilled water and in the dye bath mixture were done. The summary of the results is as follows. Comparing bamboo vinegar and the pine needle extracts, the bamboo vinegar had a higher antibacterial function. In the case of natural dyeing cotton fabrics using bamboo charcoal and gardenia seeds, the additional amount of dyestuff for optimization is 10 g and 20 g respectively per 1 liter of distilled water. The suitable dye bath mixture ratio of distilled water, pine needle extract, and bamboo vinegar considering functionality and economical efficiency of dyed fabrics is 4:3:3. By using the mixture made in this study as a dye bath, improved antibacterial function, deodorization, and colorfastness can be obtained more than distilled water alone.
