This study examined the dyeing characteristics of five oriental herbs, namely Gardenia jasminoides, Sophora japonica L., Rheum coreanum, Rhus javanica L., Ginkgo biloba L., on fabrics with traditional fermentation using malt. And the properties of Hwangsu (mineral water) of Yeongcheon (Korea)as a mordant in the post-treatment of textile were evaluated. The dyeability and fastness of cotton fabric and silk to light and washing as well as different fermentation periods and temperatures were investigated, and the following results were obtained. The dyeability of the fermented and non-fermented material did not show a significant difference. Fabrics mordanted with Hwangsu generally exhibited a reddish color due to the presence of iron. The dyeing of cotton fabric and silk by fermentation and Hwangsu mordanting were found to be effective on Rhus javanica L. and Rheum coreanum. These results were confirmed through fastness to light 3 of cotton on Rheum coreanum and 3-4 of silk on Rhus javanica L., respectively. The washing fastness of both fabrics dyed with fermented Rhus javanica L. and Rheum coreanum was improved, showing higher K/S value after washing than before washing.

In this study, the dyeing characteristics of nylon fabric which is dyed with supercritical fluid were investigated. There were two dyes used in the dyeing experiment: C.I. Disperse Red 167 and C.I. Disperse Violet 93. Dyeing temperature, pressure, and leveling time were fixed at 110℃, 250bar, 60minutes, and the experiment was conducted with dyeing concentration of 0.1, 0.3, 0.5, and 0.85% o.w.f. The analysis of the experimental results was found out through the measurement of washing fastness and color coordinate. In addition, the calibration curve of each dye was drawn up and the amount of remaining dye was checked by measuring the absorbance of the residual dye. As a result of color difference measurement, as the concentration increased, the L⁎ value decreased and the K/S value increased. However, the increase in K/S value compared to the amount of input decreased as the concentration increased. The comparative experiment on the amount of residual dye(C.I. Disperse Red 167) in the pot showed that 99.14% of the amount was dyed at the concentration of 0.1% o.w.f, while it rapidly decreased to 77% at 0.85% o.w.f. C.I. Disperse Violet 93 dye also decreased from 0.5% o.w.f to 93.91%. In the washing fastness experiment of both dyes, the level of washing fastness began to decrease from samples dyed at 0.5% o.w.f. It may be because the simply absorbed dye was produced instead of completely being fixed in the amorphous region of the nylon fiber.

Research and development of nano fiber products is very active over the world. Physical characteristics and dyeing properties of nylon 66 nano fiber were investigated in this study. X-ray diffraction, DSC, analysis of amino end group, and water absorption were performed to get information concerning physical properties of nano fiber. Nylon 66 nano fiber was dyed with high molecular mass acid dyes. Effects of dyeing temperature, pH of dyeing solution, and concentration of acid dyes on dyeing properties such as rate of dyeing and the extent of exhaustion, were examined and compared to those of regu­lar fiber. It was found that nano fiber adsorbed acid dyes at lower temperature, got rapidly dyed, and its extents of exhaustion at specific dyeing temperature were higher than regular fiber. It was also observed that nano fiber could adsorb a large amount of acid dye without a significant loss in the extent of exhaustion. Washing fastness of the dyed nano fiber was lower by $1/2\~1$ grade, light fastness by 1 grade than the dyed regular fiber.

To Save energy and cost one bath/one step dyeing and finishing on cotton/polyester blends is carried out with disperse dyes in the presence of crosslinking agent. Cotton 100 %, cotton/polyester 70/30, 50/50, 35/65, polyester 100 % fabrics were used. wrinkle recovery angle, tensile strength retention and tearing strength retention were determined in according to the dyebath composition, and also determined while the concentration of DMDHEU, molecular weight and concentration of PEG were varied. Colorfastness to abrasion, washing and light were tested. For cotton and cotton/polyester blends dyed in the presence of DMDHEU/PEG, wrinkle recovery was improved. Tensile strength retention and tearing strength retention were decreased, in compared with dyed fabrics without DMDHEU. Colorfastness to abrasion was good but colorfastness to washing and to light were poor for the fabrics dyed in the presence of DMDHEU/PEG.

The effects of silane coupling agent on the performance properties of cotton fabrics treated with loess and its washing durability were investigated. Mean average diameter of loess was 17.88㎛ and main components were SiO₂, Al₂O₃ and Fe₂O₃. By using the cationic agent, the dyeability of cotton fabrics was improved. The washing durability, antibacterial property and deodorization rate were improved and very good emissivities of far infra-red rays were obtained by using the silane coupling agent. And also the mechanical properties of cotton fabrics, such as primary hand values, were improved.

The experiments about dyeing concentration, temperature and time were done using yellow, red and purple loess as natural inorganic dyes in order to verify a degree of dyeing, characteristics of color and fastness. The results were as following; 1. As a result of analyzing components of loess, purple loess was much than other loess in quartz component and coarse particles contained. This affected to the degree of dyeing. 2. The stronger dyeing concentration was, the more the degree of dyeing was improved, and yellow loess containing fine particles was the best in the degree of dyeing. 3. When it was dyed with raising up to $100^\circ{C}$ for 10 minutes after stirring for 20 minutes at $60^\circ{C}$, was better than on starting at $40^\circ{C}$ or $80^\circ{C}$ in the degree of dyeing. Also yellow loess was the best in these experiments. 4. Washing fastness of loess was low such as other natural dyes, but dyeing wasn't transferred to other textiles. On the other hand, light fastness of it was very excellent and rubbing fastness was relatively good as 3~3.5.

Dyeing liquor was extracted from flowers, leaves and stems of balsamine. Dyeing properties, colorfastness and antibacterial activities of the fabrics dyed with the balsamine extracts were investigated at a variety of dyeing conditions of differing pH. time and temperature. Wool, silk and nylon fabrics showed better dyeability than cellulosic fabrics, i.e. cotton, linen and rayon. Especially, nylon fabrics showed the highest K/S values. The dye-uptake was achieved to the highest degree during the first ten minutes of dyeing procedure. All fabrics were dyed well at $40^\circ{C}$ with no pH adjustment. The pH of unadjusted balsamine extracts was 4.6. Their colorfastnesses to washing, drycleaning and perspiration were good as 4 or 4-5 grade. but the light fastnesses were poor as 1-2 grade. While, the antibacterial activities to Staphylococcus aureus and Klebsiella pneumoniae were excellent with 99.9% of colonies reduction ratio. Their excellent antibacterial activity was kept well after ten times washing.

This paper is to study the characteristics of fabrics dyed with astringent unripe persimmon juice. The cotton silk rayon and nylon fabrics were dyed with astringet unripe persimmon juice. The structures of natural fabrics dyed fabrics and dyed fabrics followed by washing were examined by scanning electron mi-croscopy. Surface reflexibility of VIS trans-mittance of UV VIS and NIR were analyzed. The study conclues as follows: 1. Colour of cotton fabrics dyed with persim-mon juice became darkended as a function of exposing time to sunlight. That colour was chaged after washing. 2. Blocking effect of ultraciolet light and visible ray was increased in all dyed fabrics. Especially dyed cotton fabric blocked UV light perfectly and the blocking effect was still remained after 9 washings. 3. Persimmon juice dyeing produced coating effect to fabrics besides dyeing effect accord-ing to the scanning electron micrographs. In a word the cotton fabric dyed with per-simmon juice has blocking effect of UV light stiffness. Therefore I think persimmon juice dyeing is a very useful textile finishing and ex-pect a wide application of the technique in fu-ture.
