The purpose of this study is to investigate the efficacy of juglone, which shows hish affinity to wool, for hair dyeing as a natural dye. Before dyeing hair with juglone, virgin hair was bleached by a conventional method using hair shops in the city. In order to study the dyeing properties of juglone on hair, the effects of dyeing conditions on dye uptake, color, tensile strength, and morphology were investigated. And the effect of Fe-mordanting on color change was also investigated. Dye uptake changed marginally as dye concentration increased in the range of 0.02-0.04g. Dye uptake increased progressively is dyeing time increased in the range of 10-20 min. Juglone produced YR colors on hair and the color of dyed hair got duller as juglone concentration increased. The hair was little damaged by bleaching, but cuticles were melted and stripped away by dyeing for longer time. Tensile strength retention decreased up to 65% at 20 min dyeing. Simultaneous mordanting with Fe did not improved dye uptake, but led to darker brown color compared with unmordanted hair.

This paper investigates the physical properties such as water absorption, drying and hygral expansion of moisture responded transformable fibers and their knitted fabrics including dyeing characteristics according to the different dyeing time and temperature. For this purpose, three kinds of covered filament yarn specimens using HEF and spandex as core and PET, aerocool as a covering filament were prepared. The knitted fabric specimens were made using three kinds yarn specimens and dyed with different dyeing temperature and time. The moisture absorption, drying and hygral expansion of three kinds of knitted fabric specimens were measured and discussed with yarn structure. The wearing performance of these knitted fabric specimens were also measured and discussed with yarn characteristics using FAST system. Finally, the dyeing characteristics such as dye affinity, color difference and color fastness to washing of these knitted fabric specimens were measured and discussed with different dyeing temperature and time for examining dyeing process performance of these moisture responded transformable knitted fabrics.

Historically, dyed textiles were symbols of status and, because of their expense, reserved only for people of wealth and specalist, Early dye sources probably included plant, animal and mineral extracts. As synthetic dyes have been developed, beginning with synthetic indigo in 1897, reliance on natural dye sources diminished. But renewed interest in natural dyes is fueled by a pro-environment consumer aware of the ecological liabilities of the dye industry. Han Jee was imported from China where it was influenced to period of the three kingdoms(Silla, Baekje, Kokuryo). After that, Han Jee was used for paper in old Korea for long thime before paper was came with civilization. In this paper, dyeing of Han Jee with loess were investigated according to dyeing temperature, dyeing time, loess concentration, and effects of additives. As a reuslts, λmax of Han Jee dyed by loess was 710nm. ΔE values of Han Jee increased by loess concentration, dyeing time, dyeing temperature. Dyeing with additives treatment increased dyeability. Especially, Han Jee treated with aluminium acetate shows the largest dyeability of the Han Jee. The Han Jee dyed loess had very good lightfastness.

To be dyed with cationic Berberine, the cotton fiber was modified with reactive anionic agent. The Berberine, a natural cationic colorant of pure yellow, is the major component of Amur Cork tree extract and also can be employed as a natural antimicrobial agent due to its characteristic of cationic quaternary ammonium salt. By LC/MS analysis, it became obvious that the Berberine was contained in Amur Cork tree extract as a major color component. The adsorption of the Berberine on the cotton fabrics pretreated with the anionic agent was greatly increased comparing to that of untreated fabric. Because the anionic agent was colorless, it did not cause unintended color change of the dyeings. The dyed fabric with the Berberine has strong antimicrobial activity showing 99.5% of reduction of bacteria against Staphylococcu aureus.

Natural colorants haute attracted much attention all over the world because of their non-hazardous nature. The world is becoming increasingly aware of environmental Issues, such as ozone layer depletion, water pollution and waste disposal problems. The use of synthetic dyestuffs for their synthesis and application in the dyeing industries has been criticized due to introduction of contaminants into the environment. This has led to the desire to turn to the traditional, and more natural way of life. In this study, the colorants of extract of Ginkgo biloba bark were analysed and their dyeing properties on silk, wool and cotton were studied. It was found that uv-visible absorption spectra of extract of Ginkgo biloba bark showed two strong absorption Peaks in the range of 240 ∼400 In. From the result of IR spectra, the major ingredient of extract of Gikgo biloba bark seems to be the flavon which is one of the flavonoid derivatives. Silk, wool, and cotton dyed with the extract of Ginkgo biloba bark showed a reddish yellow color. Their color differences were increased drastically with repetition of dyeing by three times.

To improve poor dye uptake of safflower yellow colorants, cellulose fibers were pretreated with chitosan. The effect of chitosan pretreatment on the dyeability of safflower yellow colorants to cotton, ramie, and rayon was investigated in terms of dye uptake, color, and colorfastness. Irrespective of fiber types, dye uptake increased continuously with increase in chitosan concentration. Chitosan pretreatment improved dye uptake up to 5.6 times for cotton, 7.2 times for ramie, and 3.7 times for rayon. For cotton and ramie, the shade of dyed fabric changed YR color to Y color with increase in chitosan concentration. Dyed rayon fabrics showed Y color irrespective of chitosan concentration. Shades got darker and deeper with increasing chitosan concentration. Shades of chitosan pretreated fabrics were shifted differently depending on dyeing temperature within same fabrics. In common, the color of all dyed fabrics changed to YR at 50 and $70^{\circ}C$ while Y color at 30 and $90^{\circ}C$. V and C value decreased with increase in dyeing temperature and resulted in darker and duller color, in general. Light fastness was fair while washing fastness was poor. It was confirmed that ultrasonic dyeing method enhanced dye uptake more than 30% for cotton and ramie fabrics compared to the conventional automatic machine dyeing method. However, no difference in dye uptake between two dyeing methods was found for rayon.

Turmeric is aromatic, perennial herb, up to 1m high and distributed in East Asia. Parts used of it Rhizomes and is known to be used a medicinal stuff yellow dye stuff from past to nowadays in the Oriental region. The objectives of this study were to investigate and to compare to the dyeability of Turmeric according to pH, temperature, mordants, and the antimicrobial properties of wool dyed with turmeric. The results of this study are as follows: The wavelengths of the strongest absorption of Turmeric extract were 420 nm respectively. The extracted dye from Turmeric has affinity to wool. The dyeing rates are decreased according to diluting times and the dyeing rates are increased according to high temperature. The color of pH 3-7 is yellow green, over pH 9 is turned to orange yellow. The color of the non-mordant sample is yellow but it changed to bright yellow by Al, to orange yellow by Cu mordant, and to brown yellow by Fe mordant. The launder fastness and is not good, 2-4 grade and the light fastness is bad, 2-3 grade, but the dry-cleaning fastness is generally good, 4-5 grade. The fabrics dyed with Turmeric extract showed high antibacterial property on Staphylococcus aureus.
