This study was conducted to clarify the effects of different natural mordants and mordanting methods on the dyeing degree of silk using extracts from Coreopsis drummondii. Surface colors were shown as an order of descent Y in control, and an order of descent Y and YR treated by mordants. Extracts from Coreopsis drummondii was sufficient for the natural dyestuffs. $10\%,\;20\%\;and\;30\%$ mordants made from lime-juice of Camellia japonica, oyster shells. and Symplocos chinensis (Lour) Druce for. pilosa (Nakai) Ohwi were used for the dyeing of silk. Surface color of silk was not affected by the concentration of mordants and mordanting methods, however, $20\%$ mordant was suitable for the dye coloring. It was shown that dye coloring concentrations were highly in the order of mordanting later > mordanting ahead > co-mordanting, and so on. Silks were naturally dyed by the extracts from Coreopsis drummondii, and twenty-nine kinds of natural mordants were treated and screened. Surface color of silk was shown as an order of descent YR treated by the mordants made from the lime-juice of Camellia japonica and Eurya japonica, and as an order of descent Y by the other mordants. By the treatment of natural mordants, concentrations of dye coloring were significantly increased compared with control (none-mordanting), and the potentials as a natural mordant for the effective dye coloring was sufficiently ascertained.

This paper investigated the dyeabiltiy and surface color of Han Jee dyed with Gardenia extract after mordanted with mordants under the various dyeing conditions. The results obtained were as follows 1) λmax of the dyeing Han Jee dyed with Gardenia appeared at 660 and 710nm. 2)K/s value of dyeing Han Jee was increased when dyeing condition, temperature, time was higher. 3) Surface color of Han Jee with mordants changed differently according to the mordants used : 3.2Y by Aluminum acetate, 2.0GY by Copper sulfate, 9.5YR by Iron sulfate. 3.4Y by Tin chloride, and 4.5Y by non-mordanting.

지역의 역사성을 지니고 발전한 전통색은 지역 문화와 자연환경에 영향을 받는다. 전통색은 일반적으로 관용색명으로 표현하는데, 이는 세계인의 공용어가 아니므로 우리의 천연염색을 국내외 일반인과 공유하기 위해서는 표준화된 색명(KS-계열색, RGB, CMYK)을 사용하는 것이 필요하다. 우리나라에서 염료재로 활용된 염료식물은 393종으로 알려져 있다. 본 연구에서는 염료식물의 자원 활용과 그 보전적 가치를 알리고자 염료식물을 언급한 고문서 및 현대자료를 바탕으로 사용 부위, 매염제의 종류, 염색 시 발현 색상의 관용색명을 조사하였고, 이를 국가표준색상환에 대입하여 표준화에 대한 방향성을 제시하고자 한다. 연구 결과에 따르면, 염료식물 393종 중 관용색명을 가진 염료식물은 312종이었고, 관용색명의 정보가 없는 식물은 81종으로 나타났다. 염료식물의 사용 부위 정보를 가진 식물은 187종이었고, 이용부위는 식물체 전체(전초), 뿌리, 줄기(껍질), 줄기(심재), 나뭇가지, 잎, 열매(껍질), 꽃이었다. 염료식물에 활용되는 매염재는 15가지(천연 6종, 화학 9종)로 나타났다. 관용색명을 가진 염료식물 312종에서 조사된 540개 관용색명을 표준화 시키기 위하여 국가표준색상환에 대입한 결과, 표준화된 색명(KS계통색명, RGB, CMYK)을 갖는 식물은 127종, 관용색명은 있지만 표준화된 색명을 확인할 수 없는 식물은 185종인 것으로 나타났다. 향후 염료식물을 연구하는데 있어서 관용색명의 정보가 없는 염료식물에 대한 표준화된 색명을 찾아내는 연구가 이루어져야 할 것이다.

Natural pigments have many applications like colouring agent, pigments, food additives, and antiseptics. At present, instead of synthetic pigments that have contributed to the development of industry, many kinds of natural pigments have been developed. The constituents of gardenia fruits, Gardenia jasminoides ELLIS, are traditionally known as herb medicine and natural dyes/pigments due to the customer is needs. The fruits produce yellow carotenoid pigments and iridoid compounds. The two main components in the yellow pigments are called crocin and crocetin. The extraction mode of yellow pigment from Gardenia is depended upon the extraction time, temperature, and volume of solvent. Red pigments or blue pigments formed from geniposide and amino acids have been reported a lot. Geniposide, the principal iridoid glucoside contained in gardenia fruit, was hydrolyzed to genipinic acid or genipin as a precursor for the pigment by enzymatic or chemical reaction. These red or blue pigments prepared with materials hydrolyzed of geniposide and amino acid and had properties governed by the electrostatic character of the amino acid. The pigments showed good stability to heat and pH but were gradually bleached by light while the other natural pigments are unstable in light, heat, acid, and base solution. The safety of the pigments was considered to be of little virulences in comparison to synthetic pigments.
