  • Recently, it has been reported that chemical hair coloring can cause allergic reactions, the toxicity issue of chemical hair color was issued. Therefore, there is an increasing interest in the hair coloration technique using non-toxic and bio-compatible hair color gotten from natural resource. In this study, the possibility using fermented Indigo as natural hair coloring agent was investigated. Bleached hair samples were dyed using Indigo, and the effect of dyeing frequency, the physical change after dyeing, color, surface and cross-section characteristics, and tensile property were also studied. In addition, the protection property of cationic detergent finishing on damaged hair samples were also studied. The following conclusions are made; 1. While bleached hair samples with low value showed the negligible effect of repeated dyeing, bleached hair samples with high value showed the good effect of repeated dyeing. 2. Hair sample dyed with Indigo showed a high light-fastness, however, tensile strength and elongation showed very low values (high damage on hair sample). 3. Cationic detergent finishing did not affect on the colorfastness because of decoloration after dyeing, however, it increased the smoothness of hair sample, and therefore, can use as protectant of damaged hair. 4. Hair scale was damaged after dyeing. It seemed that the alkali, potassium carbonate, increased pH of dyeing bath to 11, as a result, the hair was swollen, weaken, and dissolved on the prolonged dyeing time. Dyed hair sample became stiff and fine. 5. The color difference was 4.62 (a high fastness value) in the test of sunlight exposure, shampoo, cationic detergent finishing, and acid perspiration fastness.

  • Dyeing and fastness characteristics of 100% meta-aramid fiber were investigated with cationic dyes and swelling agents under various dyeing conditions such as dyeing temperature and pH of dye bath. Dye exhaustion started at around $80^{\circ}C$ and settled down at $130^{\circ}C$. Among swelling agents used, N-methyl formanilide showed comparatively higher K/S values comparing to 1-phenoxypropan-2-ol. Under weak acidic conditions in the range pH 5 to 7, the exhaustion of cationic dyes could be enhanced leading to higher adsorption and stability of colorimetric property. Wash and rubbing fastness were generally good but low light fastness found can be attributable to the poor photo-stability of the cationic dyes.

  • The purpose of this study was to investigate the dyeability of silk fabrics with sweet potato stem leaf extract. To obtain the optimal dyeing conditions it was examined at various dyeing conditions(temperature, pH, time and bath ratio). The dyeability and the depths of shade which were evaluated in terms of K/S and CIELAB color difference values of the dyed and mordanted fabrics were also investigated. After dyeing, various color fastness(wash fastness, dry cleaning fastness, light fastness, rub fastness, and perspiration fastness) was measured and reviewed for UV protective, deodorant and antimicrobial functionality. The optimun output, as a result, was shown at 100% of dye concentration, $90^{\circ}C$ of dyeing temperature and 80 minutes of dyeing time while in terms of dye uptake depending on the kind of mordants and mordanting, it was found that among four mordants of $Alk(SO_4)_2$, $CuSO_4$, $SnCl_2$, and $FeSO_4$, post-mordanting with $SnCl_2$ showed the best results. Color fastness to dry cleaning, washing and rubbing was found strong at grade 4-5 and the grade to perspiration was as good as 3 while to light fastness was good at 4 as well. In aspects of functional properties, it showed excellent results of 98.3% UV protection rate and 88% deodorization rate. Antibacterial activity was 99.9% against staphylococcus aureus and 73.3% against klebisella pneumoniae. In conclusion, we validated that the dyestuffs from the disused sweet potato stem leaf extract would be useful as a natural dye material using the optimized conditions and dyeability for silk dyeing.

  • Cotton fabrics was treated with persimmon juice by padding and their dyeability and functionality were assessed including antibacterial activity and deodorization ratio. The merit of padding-based dyeing was easier color reproduction over traditional hand dyeing where various colors and color fastness to light and laundering are hard to obtain. With larger number of padding, the dyed fabrics showed deeper red-yellow colors, which had low brightness and high chromatic colors. The dyed cotton fabrics had a perspiration fastness of 4~5 rating, a rubbing fastness of 3~4 rating, and a washing fastness of 4 rating, As the number of padding and exposed time to sunlight or UV light increase, the values of K/S and ${\Delta}E$ increased and the colors became much deeper gradually. The color development had completed about 70 hours exposure to UV. Among the light sources, the dyed fabrics exposed to UV light showed deeper yellow-red color than those of exposed to sunlight. The cotton fabrics treated with premordants like Al, Cr, Cu, and Sn revealed strong yellow colors, especially the fabrics treated with Fe mordant showed greenish red-yellow colors. As the padding times of dyeing with persimmon juice increased, stiffness and water repellent property were enhanced in warp and weft directions, respectively. Also, the dyed fabrics have good antibacterial activity and deodorization.

  • The results of the analysis of dyed rayon fabrics treated with persimmon juice by padding are as follows. Rayon fabrics were dyed repeatedly with persimmon juice by a padding mangle for the development of dyeability. The merits of padding-based dyeing were easier color reproduction (versus traditional hand dyeing) of hard to obtain colors and color fastness to light and laundering. The add on weight increased with the number of padding times, and the color of the dyed fabrics had red-yellow colors with low brightness and high chromatic colors. Properties of fabrics treated with persimmon juice were: $2^{nd}$ level of light resistance, $4^{th}-5^{th}$ perspiration fastness levels, rubbing fastness, and $3^{rd}-4^{th}$ washing fastness levels. Dyed fabrics exposed to UV light have a deep yellow-red color that increased lightness and darken when exposed to sunlight. Rayon fabrics of a treated premordant indicated strong yellow colors, especially fabrics with Fe mordant indicated greenish red-yellow colors. The direction of the weft and warp increased and improved water-repellent qualities that increased with the number of dyeing padding times and persimmon juice; however, there was less anti-crease resistance. In addition, fabrics had good antibacterial activity and deodorization.

  • Oxidative hair color is currently widely used because of its beautiful light color and good dyeability. In this study, hair color, oxidative agents, and dye intermediate were reacted. Modifier, which changes color with various hue, and alkaline agent, which opens the cuticle of hair fiber and enhances the dyeing reaction, were added. For gel formation, isocetyl alcohol was used as solvent in preparing three kinds of permanent oxidative hair color. Physiochemical study of prepared permanent oxidative hair color was done for basic information acquisition. Acid perspiration test, pH measurement both at room temperature and at high temperature, drop movement test, dyeability efficiency upon the amount of hydrogen peroxide added, and humidity fastness were studied. Shampoo fastness and light fastness of prepared permanent oxidative hair color dyed hair sample were also investigated. All three kinds of hair color prepared showed good properties overall, however, dyed hair sample became reddish upon shampoo fastness and lightfastness tests.

  • This research verified the usefulness and practicality of citrus peel extract as a natural dye. This study dyed cotton, silk, and cotton/mulberry fiber blended fabrics using citrus peel extract, and measured the dyeability and functional property to verify their usefulness and practicality. The dyeing affinity of the citrus peel extract was measured by dyeing under alkaline conditions to determine the temperature and time for optimal dyeing conditions of the solution. The results show that a temperature and time of $60^{\circ}C$ and 30 minutes were optimal for dyeing cotton fabrics with citrus peel extract, $50^{\circ}C$ and 60 minutes for silk fabrics, and $60^{\circ}C$ and 60 minutes for cotton/mulberry fiber blended fabrics, respectively. In addition the results of measuring the color fastness of the cotton, silk, and cotton/mulberry fiber blended fabrics dyed with the citrus peel extract show that the color fastness was superior for washing, friction, sweat, and water. However, the color fastness for sunlight appeared to be slightly weak. In addition, it was found that fabric dyed with the citrus peel extract showed partial antimicrobial properties. The antimicrobial property appeared the greatest in the silk fabric. The cotton/mulberry fiber blended fabrics had 90% or more Staphylococcus aureus present, but the antimicrobial properties were not high in the cotton fabric. Additionally, the heavy metal content, which is harmful to the human body, appeared to be lower than standard figures, so the dye was found to be innocuous to humans. Therefore, when the results of this study are put together, citrus peel extract is sufficiently useful and practical as an ingredient for a natural dye. Moreover, there is ample possibility to develop citrus peel dyed fabrics as environmentally friendly fashion materials.

  • Recently, polyester is widely used in textile fabrics due to its application potentials in various fields. It is known that askin fabric is prepared with mainly polyester and is enjoyed with various end uses such as marine clothing, underwear, shirts, swimming suits and so on. For this purpose, color fastness should be considered with great importance during its wet processing step. In this context, vat dyes were very much attracted due to the advantage of superior fastness property. Thus, we have used indigo dye towards askin fabric dyeings and investigated corresponding properties namely, dyeing temperature, concentration of dye, reducing agent amount and alkali amount. The results showed that higher color strengths of indigo dyeing on askin fabric were obtained at $110^{\circ}C$, 8% o.w.f, 3g/l, 5g/l, respectively. The color fastness to washing was considerable generally.
