This study was performed to investigate the effect of Mentha arvensis Herba extract on the treatment of chromaticity and colorfastness. Mentha arvensis Herba has been used as a Korean medicine. It is effective in headache and stress. It is also good as a aphtha and in treating cold. In the long history of Korea, dyeing has been applied for a means representing the grace of natural and inner esthetic consciousness of man. Vegetable dyes give us such great benefits, diversified color, but no pollution. And ramie fabric has distinctive features such as beautiful brilliance, elegance, and strong durability. So, it is regarded as a special product of Korea traditionally. These studies were carried out to treat with acetate iron, dichloride copper and alum with a mordant to ramie fabric. The ramie fabric was died with Mentha arvensis Herba extract. The results of experiment showed as follows: First, the chromophoric degree was the highest in acetate iron but not distinction in another mordants. Second, the light colorfastness was the highest in non treated and dichloride copper, but alum was the lowest. Third, the discoloration was alum and dichloride copper showed first grade in washing colorfastness. Abrasion colorfastness was not significant in this test. According the previous results, Mentha arvensis Herba has an efficiency in removing aphtha and in treating cold. So it is considered that Mentha arvensis Herba can be applied effectively to headache and stress.

This study shows the dyeability and antibacterial activity about cotton and silk fabrics dyed with Chrysanthem indicum L. In the case of dyeability, in the first, K/S value was shown comparatively high numerical value. The value of all test sample was over 20. In the next, in the case of colorfastness, the light colorfastness showed the lowest grade, the other colorfastness was relatively good. However there are some differences according to fabrics and mordants. In the case of antibacterial activity to Klebsielia pneumoniae, the cotton fabrics had the most antibacterial effect at the dyed fabrics that had been mordanted $CuSO_4$.$5H_2O$, and the silk fabrics had the most antibacterial effect at the dyed fabrics that had been mordanted $CuSO_4$.$5H_2O$.$Al_2$ and $(SO_4)_3$.

The purpose of this study was to investgate dyeing, moradnting properties and colorfastness activities of silk, polyamide, acetate treated black soybean extracts. The color of extract by buffer solution (pH=1) red, but the higher pH of extracted black soybean solution the paler of color strength. Black soybean extracts was approved anthocyanin of 3type(Delphinidin3-glucoside, Cyanidin 3-glucoside, Petunidin 3-glucoside) by chemiclal analysis. This anthocynin, in acid condition, is oxinium structure (red color, soluable) but, in alkali condition quinoid structure(dark brown, in soluable). The optimum dyeing condition of black soybean anthocynin was 10min at $30^{\circ}C$, pH -1. Colorfastness to washing and light showed generally low but crocking fastness was excellent.

This study used Jeju scoria to dye cotton fabric and measured its dyeability, colorfastness, antibacterial activity, deodorization efficiency, ultraviolet protection, and far-infrared emission. The cotton fabric was colored to yellowish red and optimal dyeing can be achieved at a temperature of $80^{\circ}C$ for a dyeing time of 120 minutes with a colorant concentration of 25%(o.w.b). The colorfastness to light, rubbing, perspiration, and washing was 8, 5, 5, and 4~5 ratings respectively, where the wash colorfastness remained after 15 wash cycles. The cotton fabric dyed with Jeju scoria demonstrated excellent antimicrobial activity to Staphylococcus aureus and high deodorization efficiency. Ultraviolet protection factor was as high as 50+. The Jeju scoria can be used as a new colorant for the natural dyeing of silk.

The natural dyeing of silk fabric with Scutellaria baicalensis extract was investigated. The proper colorant concentration, dyeing temperature, dyeing time, and pH for the dyeing of silk fabric with Scutellaria baicalensis extract were 90% v/v, $90^{\circ}C$, 60 minutes and pH 3, respectively. In various mordanted methods, the K/S values of mordanted methods were higher than those of unmordanted methods. Light colorfastness and washing colorfastness of Fe mordanted silk fabric was improved by mordanting. The antibacterial properties of dyed and mordanted silk fabric showed a high reduction rate, and Scutellaria baicalensis extract was showed effective bacterial reduction.

The colorante from black tea infusion were applied to cotton fabric. Dyeing properties were investigated in terms of dye uptakes at various dyeing conditions and the effect of mordants on color change and colorfastness. Cotton showed low affinity to black tea colorants. Effects of mordants on dye uptake was not significant except Sn. Irrespective of mordant type, color of cotton dyed with black tea colorants was brownish and colorfastness was generally good. In order to improve dye uptake, cotton was cationized by treating with Cationon UK(tertiary ammonium salt) and chitosan. Dye uptake of cotton was remarkably increased by cationizing. Cationon UK was more effective than chitosan.

The purpose of this study is to investigate dyeing properties of wool fabric with walnut colorants. Walnut colorants were extracted with water from walnut hull and characterized by FT-IR analysis. Effects of dyeing conditions and mordanting on dyeing properties and colorfastness were studied. Results obtained were as follows, 1. Higher K/S value was obtained at higher temperature and longer dyeing time, the highest K/S value was shown at 100℃, 60min. 2. Dye uptake was increased with the increase in colorants concentration up to 2%. Higher K/S value was obtained at acidic condition. 3. Mordanting was not effective for improving dye uptake and colorfastness and for changing color of the dyed fabric.

Dyeing properties of the colorants extracted from pomegranate hull on silk fabric were investigated. Pomegranate colorants were characterized by FT-IR analysis. Effects of dyeing condition and mordanting on dye uptake, color change and colorfastness were explored. Pomegranate colorants showed high affinity to silk fiber and its isotherm adsorption curve was Langmuir type. Therefore, ionic bond was involved in the adsorption of pomegranate colorants on to silk fiber. Mordants except Fe did not significantly increase dye adsorption. Pomegranate colorants produced mainly yellow color on silk fabric, but the silk mordanted with Fe showed yellow red color. Fastness to washing, perspiration, and rubbing was not improved by mordanting treatment, but light colorfastness was increased by Fe mordant.

Wool fabrics were treated with deep UV for 10 to 30min and then dyed with C.I. Acid Yellow 99, C.I, Acid Red 57 and C.I. Acid Blue 62. FT-IR and XPS have been used to prove the chemical composition of wool fiber surfaces. The mechanical property and colorfastness were also studied. The intencities of the peaks of C=O group at $1700^cm^{-1}$ were increased with increasing irradiation time. Relative $O_{1s},\; N_{1s}\; and\; S_{2p}$ intensities increased considerably and oxygen was incorporated in the form of CO and COO on the fiber surface. The dye uptakes of wool fabrics dyed with three acid dyes were proportional to irradiation times and in inversely proportional to irradiation distances. It was found that the tensile strength of wool fabrics were gradually deteriorated with the UV irradiation times. The colorfastness, such as washing, light and rubbing, of UV irradiated wool fabrics dyed with acid dyes were good.
