천연염색은 인공염료로 인한 환경오염으로부터 자연을 보호하고, 천연 염색된 섬유는 해충으로 인한 인체의 피해를 막아주어 의복, 침구 류로 개발 가능하며, 또한 색상도 중간계열이 많아 자연스런 이미지를 연출 할 수 있다. 본 연구는 값싸고, 쉽게 구할 수 있는 천연염색 재료를 다양한 색상으로 개발 할 수 있어 고부가가치를 지닌 제품 생산으로 유휴농지의 활용과 함께 농가의 수익을 올릴 수 있다. 전라남도 무안 지방에서 대량으로 생산되는 양파껍질을 다양한 섬유에 염색하여 노랑 색에서 연갈색, 회색계열까지 여러 가지의 색상이 추출된다. 이렇게 염색된 섬유의 세탁, 마찰, 물, 땀, 일광 견뢰 도 측정을 통해 실험하였더니 그 결과 견뢰 도가 전체적으로 우수하여 천연 산업 염색재료로서의 가능성을 발견하였다.

본 연구의 목적은 양파 외피를 분상의 상태로 제조하여 모발염색의 최적에 조건을 규명하기 위해 V.H.에 4회 탈색 (B.H.)하여 시험모를 제작한 후 양파 외피 추출물을 시간, 온도, 농도, pH, 매염제 처리별로 조건을 달리하여 모발의 염색성과 기계적 형태학적 변화를 관찰하였다. 모발 표면을 주사전자현미경을 통해 관찰한 결과 모표피층이 완전 용해된 B.H.에 비해 양파 외피 추출물로 염색한 모발에 경우 약간 들떠있는 상태는 보이지만 모표피층이 형성되어 있는 것을 관찰할 수 있었다. 이와 같은 연구의 결과로부터 양파 외피에서 추출한 천연 색소는 분상의 염모제로 제조 시 대량 생산과 보관에 있어 효과적으로 실용화가 충분히 가능하다고 사료된다.

Natural dyes are environmentally and human compatible. But they are not various or not fast in color. The mixed dyeing have been attempted to solve these disadventages of natural dyes. The persimmon juice dyed fabrics have brown-color and good hygienic properities however low color fastness. The onion dyeing show similar brown-color and have good color fastness caused by querectin existed in onion outer skins. Mixed dyeing was carryied out on silk fabrics using persimmion juice and onion outer skin extract in this study. The mixing method were persimmon juice dyeing and then onion dyeing(P-O), onion dyeing and then persimmon juice dyeing(O-P) and dyeing in the mixture of persimmon juice and onion outer skin extract simultaneously(P+O). The mordants were none-mordent, gallic acid after-treatment and alum after-treatment. Several persimmon juice dyed fabrics were irradiated for 2 hours before onion dyeing(PU-O). The color values of dyed silk fabrics were as follows. The persimmon juice dyed silk fabric developed to yellow-red color after 2 hours of uv irradiation. Onion dyed fabrics show similar yellow-red color after dyeing without uv irradiation. The effect of alum after-treatment on color difference were highest in onion dyeing. The dyeabilities of both P-O and O-P were higher than persimmom juice dyeing and onion dyeing. The dyeabilities of P+O was lower than persimmom juice dyeing and onion dyeing. The value of color difference of alum-treated fabric was the highest. The color difference of P-O and O-P caused from 2 to 4 hours of uv-irradiation were lower than those of persimmon juice dyed fabrics. Onion skin extract could prevent the color-change of persimmon juice dyed fabrics in mixed dyeing. The color difference of PU-O was higher than the P-O.

This study explored Jeju natural resources with healing function and tried mixed dyeing of Ecklonia cava and onion shell to improve dyeing. The results showed that silk dyed with a mixture of Ecklonia cava powder and onion shells rather than Jeju's individually dyed silk had better color power to develop fashion products. In addition, all friction lightning bolts, dry cleaning and sweat mining levels were excellent as well as excellent UV protection rates. The three baenaet jeogori worn during a birth anniversary and four rest suits that infants and children can wear comfortably maintained the dyeing and functioning of Ecklonia cava and onion shell mixture that was proven through abnormal experiments. For the three baenaet jeogori and two rest suits, the company has developed a fashion product recognized for high value-added merchandise using a variegation dyeing method made in a handmade style for expressing a person's natural sensibility through dyeing fabrics. Based on the results of the above research, it is expected that various fashion product developments will be possible by dyeing a mixture of functional and colorful extracts of the drug and colorful dye.

In this study, the dyeing of Chrysanthemum indicum Linne alone and the combined dyeing of Chrysanthemum indicum Linne and onion shell were first performed to compare dyeing properties. A combination extract of Chrysanthemum indicum Linne and onion shell can be expected to improve coloration. A Hanbok design for children used a natural dyeing fashion dyeing method to make the Chrysanthemum pattern. Chrysanthemum indicum Linne is a type of wild chrysanthemum with various medicinal effects for headache and stress relief, skin diseases, insomnia and depression. Widely used onion shells have medicinal properties that help prevent and treat various adult diseases. The colors of silk dyed exclusively by Chrysanthemum indicum Linne, and the colors of silk dyed by Chrysanthemum indicum Linne and onion shell extract are yellow; in addition, silk dyed by Chrysanthemum indicum Linne and onion shell extracts were almost all unchanged. Four hanboks, which are comfortable for children to wear and use, were produced using Chrysanthemum indicum Linne and onion shell extracts. If children wear hanbok fashion products with auspicious patterns, they can provide a chance to simultaneously experience the traditional symbolism of Korean patterns and culture. In addition, it is expected to develop pride in traditional dress culture.

In this study, UV/vis. spectra of color solution extracted from onion shell and dyeing properties of polyamide fibers such as wool, silk, and nylon were investigated. Also, the effect of mordanting on wash fastness and light fastness was Investigated. The amount of colors extracted was increased with extracting temperature and time. The wavelength of maximum absorption of onion shell extract corresponds to flavonol peak and quercetin peak. Also, spectra of color solution were shifted to longer wavelength at higher pH values. It appeared that the optimum condition of the dyeing of wool, nylon, and silk fabrics with onion shell extract was $60^\circ{C}$ , 30min, and pH 4.0 of dyed bath. Surface colors of the dyed fabrics were different according to the used mordants: Al and Cr mordanted fabrics were dyed in yellowish colors, Cu mordanted fabric in greenish color, Sn mordanted fabric in orange color, and Fe mordanted fabric in khaki color. The mordanting was effective at improving wash fastness and light fastness.

This study aimed to investigate the efficacy of eco-friendly leather dyeing by utilizing food wastes. Natural dyeing of eel skin was attempted using onion peels which have been used commonly for natural dyeing of textile fabrics. Eel skin is a by-product from fishery processing and is used mainly for making leather products. The colorant was extracted from onion peels in boiling water, concentrated, and freeze-dried. Dyeing of eel skin was carried out to study the effects of dyeing conditions, mordant type and mordanting method on dye uptake, color change, drape stiffness and colorfastness. The optimum dyeing conditions were $60^{\circ}C$ of dyeing temperature, 60min of dyeing time at 1:100($H_2O$ 90%: ethanol 10%) of bath ratio. The onion peels produced yellowish color on eel skin. The pre-mordanting was effective than the post-mordanting. As a result of the drape stiffness measurement, the Fe-mordanted sample was somewhat stiffer comparing to other mordanted samples. The light fastness of the non-mordant dye was excellent in 3-4 grade. Drycleaning fastness and rubbing fastness showed excellent results, but fastness was not significantly improved by mordanting.

Coffee sludge and onion shells are known typically as waste resources as well as simultaneously being the raw material for dye having a golden brown color. This research studies the dyeability, functionality, and colors of woolen fabric after being dyed by different dyeing method using coffee sludge and onion shells extract. The woolen fabric was refined and pre-mordanted with tannin. The dyeing process conducted was single-dye, using coffee sludge and onion shells extract, sequential multi-dye, consecutively dyeing with coffee sludge and onion shells, and mixed-dye, blending coffee sludge extract and onion shells extract to dye. The dyeing was measured on the surface color, color fastness, and UV-protection ability. As a result, the expression of various hues of tan using coffee sludge and onion shells extract were shown to be possible. Additionally, single-dye, sequential multi-dye, mixed-dye had generally superiority in color fastness to light, all rating 3 and color fastness to washing, rating 3 or 4, showing relatively stable color fastness to washing. The UV protection ability was shown to be better, especially appearing satisfactory in the UV-B protection, all measured to be over 90%.
