  • Fabrics dyed with artemisia extract have quite natural and elegant tones of color. This study purposed to find the best one for dyeing among artemisia collected in the four seasons in order to develop a more efficient method of dyeing with artemisia. As for the method of research, the researcher dyed wool fabric and silk fabric with artemisia, and measured dyeability according to the number of repeats of dyeing, coloration by post-mordant, color fastness to washing, color fastness to dry cleaning and color fastness to light. The results are as follows. 1. In dyeing with artemisia, dyeability was improved as the number of repeat of dying increased, and it was higher in wool fabric than in silk fabric. 2. Among artemisia collected in the four seasons, autumn artemisia had dyeability much inferior to that of artemisia from the other seasons, and winter artemisia had the best dyeability. 3. According to the result of treating fabric with post-mordant, the dyeability was improved significantly, and coloration was most remarkable when copper and iron mordant were used. 4. The color fastness to washing and color fastness to dry cleaning of fabric mordanted with artemisia were as high as grade 4-5 and grade 5 respectively. The color fastness to light was highest in winter artemisia as grade 4.

  • The purpose of this study is to investigate the absorbance of the Shikonin, one of the major purple pigments, and the stability against the effect of light, $O_2$, and temperature. The effect of mordant and mordanting condition to color and color-fastness is compared and analysed through the color-fastness-test, color-difference value-test, and IR-test. The results were as follows; 1. The absorbance of Shikonin was examinated through 6 kinds of solutions and distilled water. Shikonin was absorbed by solutions rather easily than distilled water. 2. The light effect to Shikonin indicated that the solution with the light was more stable than that without it. 3. The effect of $O_2$ to Shikonin showed that the solution with the $O_2$ was more stable that without it $O_2$. 4. Shikonin -methyl alcohol solution was stable in $25^{\circ}C$. It was unstable in $60^{\circ}C$ and $100^{\circ}C$ with lowered absorbance and changed colors. 5. Color-fastness test to silk and cotton indicated washing color-fastness and perspiration color-fastness was more than 3 grade. But the light color-fastness and crocking color-fastness was low. 6. The comparison between non -colored sample and colored-sample showed the latter was better in fastness. 7. Mordant as $Alk(SO_4)_2{\cdot}24H_2O$ and $AlCl_3{\cdot}6H_2O$ was better than anything else in fastness. 8. Color-difference value-test indicated that the mordant which had the jade green color, the original purple pigment color, was the best in use. 9. The best way to extract the original purple pigment color was in $25^{\circ}C$, because extracted dyeing solution by Soxhlet had the bluish color.

  • The natural dyestuff(chestnut dye) was manufactured from chestnut hulls by boiling in 0.5 NaOH solution and powdering in freeze dryer. To investigate the dyeability and color fastness, cotton, wool, silk and nylon fabrics were dyed under several conditions using the manufactured chestnut dye. Dyeing operation was carried in acidic dyebath of pH 4-5 because the chestnut dye is anionic. Dyeabilities on wool, silk and nylon fabrics were good, especially nylon fabrics were dyed deeper than others. But dyeability on cotton fabrics was not good. All the dyed fabrics showed excellent color fastness to crocking. Color fastness to laupdering of them were moderate to good. Also light fastness of them were moderate to good except nylon. The light fastness of dyed nylon fabrics was as poor as grade 1. But they could be improved to grade 4 by aftertreatment with gallic acid.

  • Henna is a natural colorant and has been used to dye hair, skin and leather since civilization began. It produces a reddish brown to orange shade. The major color components of Henna are Lawsone(2-hydroxy-l,4-naphthaquinone) and Luteolin (3',4',5,7-tetrahydroxy-flavone). In this study, the optimum dyeing conditions for Henna on to the wool fabrics were investigated. Wool fabrics were dyed with Henna at various time, temperature, concentration and pH conditions. Dyeing property, color fastness and anti-bacterial properties were evaluated. From the results, the optimum dyeing conditions for Henna on to the wool fabrics are 60℃, pH 7, 2% o.w.b., and 45 min. The color fastness of the wool fabric dyed with Henna to washing, dry-cleaning, and perspiration were grade 4-5. The color fastness to light was grade 3. These results are relatively good compared with other natural dyes. Moreover fabric dyed with Henna showed excellent antibacterial activity.

  • The colorants of kale powders were optimally extracted using an 1:1 mixture solvent of ethanol and DMSO at 105℃ for 30 minutes obtaining a high yield of 359.7㎍/mL chlorophylls. Low color fastness of the dyed fabrics with the extracts, particularly against washing and solar radiation, can be overcome by the combined treatments of chitosan, heat setting and tannic acid. Washing fastness to color change was improved from rating 1-2 up to 5 due to the enhanced electrostatic interactions between the colorants and the positive glucosamine unit of the chitosan in the cationized cotton. In addition, the tannic acid treatment contributed to the additional increase in color fastness after the sequential treatments of chitosan pretreatment, dyeing and heat setting.

  • This study purposes to find the best one for dyeing with artemisia in order to develop a more efficient method of dyeing with artemisia and investigates the antibiotic activities of artemisia. After dyeing cotton, rayon, silk, wool and nylon fabrics with dyebath extracted from artemisia, observation on dyeability by temperature, concentration and time has been carried out. And I took an observation on color change, color fastness to washing and color fastness to light after mordanting treatment. Also observation on the antibiotic properties of non-dyed fabrics, artemisia-dyed fabrics and artemisia-dyed fabrics with post-mordant has been performed to investigate the antibiotic activities of artemisia. And the following results have been obtained. 1. The dyeability of artemisia was better for protein fabrics such as silk or woo and amide-based synthetic fabrics like nylon than for cellulose fabrics such as cotton and rayon. 2. For all tested fabrics, the dyeability was increased as the concentration of artemisia dyebath, dyeing time and dyeing temperature was increased. Especially the dye ability for protein fabrics was most affected by the temperature, and high dyeability was obtained at high temperatures. 3. For the color fastness of artemisia-dyed fabrics with mordanting treatment, the color fastness to washing was good with grade of 4-5 while the color fastness to light ranged from grade 2 to grade 3, which requires improvement for practical use. 4. The artemisia-dyed fabrics were shown to have much higher antibiosis than the non-dyed fabrics, and the artemisia-dyed fabrics with mortanting treatment showed the following result; Cu 99.9%, Al 64% and bittern 64.7%.

  • Nano Inkjet DTP technology, a new technology introduced recently, can be applied to various types of fabric, and pre-treatment process can be omitted, which makes the whole printing process compact. Some important factors for DTP are color difference between the color selected by the designer on PC and the color on the final product and durability of the final fabrics. In this study, the twenty-three trend colors of 2012-2013 F/W suggested by PeclersParis have been picked to be printed on cotton, silk and polyester fabrics, then K/S and ${\Delta}E$ value and color fastness were measured. The results show that dyeability of fabric is varied for each color group, and that also tone of color affect to dyeability when measured for colors in the same group. In general, for all fabric, light fastness, washing fastness and color fastness to sublimation are outstanding. However, because of poor rubbing fastness, additional treatment to fix colorant on fabric is required.
