The colorants were extracted from the flower leaf of rose using a buffer solution. Dyeing properties and the fastness of silk fabrics dyed with rose flower extracts were investigated. K/S values of dyed fabrics were increased as the concentration of rose flower extracts was increased. Optimum dyeing temperature of rose flower extracts was $30^{\circ}C$. Fastness were generally good except light fastness which was extremely poor.

본 연구는 우리 야생화중 비교적 대량번식이 가능한 종인 산비장이의 줄기, 꽃, 잎을 채취하여 염액을 추출하고, 다양한 염색 조건에서 견과 면 소재를 염색하여 염색거동을 살펴보고 염색된 색상에 대하여 고찰하여 다음과 같은 결과를 얻었다. 1. pH에 따른 염색에서 견은 pH가 낮을수록 진하게 염색되었고 면은 pH가 중성일 때 가장 진하게 염색되었다. 2. 염색온도에 따른 염착량은 견과 면 구분 없이 큰 차이가 없었다. 3. 염색시간이 1시간에서 2시간 사이에서 급격한 Y값의 감소를 보여 이 시간대에서 많은 염착이 이루어 졌다. 4. 면은 염 첨가 농도로 높을수록 Y값이 낮아져 염이 촉염효과 역할을 하는 것으로 보여 졌으나 견의 경우 염첨가에 따른 Y의 값은 큰 변화가 없는 것으로 나타났다. 5. 염액 농도에 따른 염색성은 견, 면 모두 농도가 작아지면 염착량이 작아졌다. 6. 견의 경우 매염제의 대한 매염효과가 높게 나타나고 있으나 매염제 농도는 큰 영향을 미치지 않았다. 면에서 철(Fe)과 구리(Cu)에 대한 매염효과만 조금 있었다.

This research was conducted to establish the efficient use of the colored rice bran fur dyeing textiles. To investigate the fabric dyeability of the colored rice bran extract, the anthocyanin pigments were extracted with water of different temperature ranges of 40 ~ 8$0^{\circ}C$ and were dyed on silk fabrics with different dyeing temperature $25^{\circ}C$~6$0^{\circ}C$, at acidic pH and neutral pH, respectively. Aluminum chloride was preheated with mordant K/S value and dyeing fastness of dyed silk fabrics were examined. The anthocyanins of the colored rice bran were stable and red color at acidic pH, red purple or purple blue at neutral pH, but unstable, blue color at alkaline pH. If extracting temperature and dyeing temperature of dyeing solution were higher, the dyeability was high, but the color of dyed fabric showed red tone. When extracting temperature was 8$0^{\circ}C$ and dyeing temperature of dyeing solution was 6$0^{\circ}C$, the dyeability was best. Without mordant, the dyeability of silk fabrics was higher in acidic pH than in neutral pH solution. With mordant, the dyeability was higher than without mordant, and also higher in acidic pH. Pretreatment of aluminum chloride resulted in the increase of color intensity and stability. The laundering fastness of dyed fabrics was good from grade 5 to grade 3-4. Because of the anthocyanins sensitivity on light radiation, the light fastness of dyed fabrics was poor from grade 3 to grade 1-2.

This study was aimed to analyze color characteristics of silk fabrics dyed with a variety of commercial natural dyes focusing on hue/tone system. Using eleven different natural dyes, single and sequential dyeing were performed under a variety of conditions of dye bath concentration, mordanting, and dyeing sequences. Color characteristics of dyed silk fabrics were investigated by Munsell's color notation of H V/C and PCCS (Practical Color Coordination System) tones. As results, most of yellowish natural dyes as principal shades in natural dyeing showed Y or YR for hue families while d, ltg, and g for tone, which agrees with colors frequently used in comtemporary apparel industries. As for single dyeing, some hues like R, RP, G, GY, and BG were found to have their own tones owing to the used natural dyes. For varying hues in natural dyeing, sequential dyeing is useful in that GY, G, and BG rarely appeared in single dyeing were frequently shown in sequential dyeing by combination of some dyes. In the other hands, mordanting may be employed for tone variation in that aluminum seemed to contribute to light and dull tones, copper to dull, and ferrum to garyish and dark ones. These results can be helpful to design colors for fashion fields by natural dyeing.

On the whole the various medium colors were developed by repeat dyeing with different colorants after dyeing with one colorant in case of natural dyeing. In this study, however in order to obtain various colors on silk fabrics with natural dyes, pre-mordanting and combination dyeing were carried out. Metal compounds containing alum, copper and iron were used for pre-mordants. Gardenia and Sappan wood were used as colorants for combination dyeing. In combination dyeing of Gardenia and Sappan wood, these two natural colorants showed good miscibility in dye bath. The various colors were obtained according to various metal compounds for pre-mordants and various mixing portion of Gardenia and Sappan wood.

Four kinds of neutral salts with different cations, LiCl, NaCl, KCl, and CsCl, were added to the dye bath to accurately understand the effect of cations on the reactive dyeing of silk with C. I. Reactive Black 5. The cations of salts added lowered the negative surface potential of the silk, improving equilibrium adsorption and the accessibility of the dyestuff to the fiber greatly and speeding up the dyeing rate in the order of $Li^+>Na^+>K^+>Cs^+$. The activation energy$(E_a)$ for the dyeing was in the order of$Li^+>Na^+>K^+>Cs^+$ but the activation free energy$(\Delta{G}^*)$, or the real energy barrier for the reaction, was in the order of $Li^+>Na^+>K^+>Cs^+$ because the degree of the contribution of E$^{a}$ to the activation entropy$(\Delta{S}^*)$ was $Li^+>Na^+>K^+>Cs^+$. It was found from this result that LiCl had the strongest lowering effect on the negative surface potential of silk. The decrease in $\Delta{S}^*$ should be attributed to the loosely bonded activated complex of dyestufffs, cations and fiber molecules at transition state. It was clarified from the Bronsted equation that salts had the ionic strength effect and the specific salt effect on the reactive dyeing.

The objective of this study was to investigate dyeing characteristics of silk, cotton and rayon fabrics using dyeing solution extracted from different varieties of tea. Comparative results of CIE Lab values of 360 pieces of dyed fabrics were studied to quantify the effects of dye concentrations (100%, 150%, and 200%) and mordants (Fe, Cu, Sn, Al). In addition, the color difference values (${\Delta}E$) of the dyed and mordanted fabrics were evaluated. The results of the study were as follows: First, among all of the 360 pieces of silk, cotton and rayon fabrics, the best dyeing effects was observed on silk fabrics. Second, the dyeing effect of the eight different types of tealeaves belonging to green tea, oolong tea, black tea, and dark tea tended to enhance as the degree of fermentation increased. Third, when the fabrics were mordanted with Fe, Cu, Sn, Al mordants, various colors such as brown, brownish red, brownish yellow, gray, and reddish brown were obtained.

Antibacterial and deodorization properties of silk fabrics dyed with Sappan wood are investigated by Halo, Shake flask, Bioassay and Detection column methods.The results are obtained as follows; 1. Although K/S values increase with Al mordant and concentrate concentrations, these are decreased in 10% Al mordant concentration in case of 4mlg dye concentration. 2. Reduction ratios of bacteria increase with K/S values in various tests. 3. When undyed silk fabrics are treated with Al mordant, reduction ratios of bacteria are not varied with Al mordant concentrations. 4. Deodorization property of Al pre-mordanted dyeing silk fabrics is better than one of unmordanted dyeing and raw silk fabrics. 5. Antibacterial properties of Cu and Cr mordanted dyeing fabrics are better than ones of the dyeing fabrics treated with the other mordants. 6. Natural dyes extracted from Sappan wood show the good antibacterial and deodorization properties, and colorant among various components contained in Sappan wood has a excellent antibacterial and deodorization properties.

For the purpose of standardization and practicability of natural dyeing, the mordanting and dyeing properties of Acorn Shell was studied. Appropriate extraction, dyeing and mordanting condition of Acorn Shell were determined, and the effect of mordanting method on dye uptake and color fastness of dyed fabric was investigated. The maximum absorbance of Acorn Shell solution was at 287.5nm and 294nm. The pH effect was stable in the color difference changes. The optimum temperature to extract Acorn Shell was during 1 hour in $60^{\circ}C$. The effective dyeing temperature and time of silk were $80{\sim}100^{\circ}C$, 1hour. The silk fabrics dyed with Acorn Shell appeared yellow-brown. K/S value of dyeing fabrics was increased by mordant treatment. K/S value of post-mordanting was higher than pre-mordanting. Mordanting treatment attected color change of the dyed silk. In the case of Acorn Shell light fastness of appeared more than 3-5grades by post-mordanting. Abrasion fastness of appeared more than 3-5grades. Perspiration fastness of appered more than $3{\sim}5grades$ by mordant treatment but Cu mordant treatment was $2-5{\sim}4grades$. Dry-cleaning Fastness appered more than 4 grades except Cu mordant treatment. These fastness improvement were generally effective for mordant treatment, specially Al, Sn, Cr.
