The study has focused on the dyeing properties of 4 kinds of high temperature type mono azo disperse dyes, widely used in the dyeing factory, under the ultra low liqour ratio (1:4) dyeing condition. Among those, C.I. Disperse Red 343 and C.I. Disperse Blue 79 showed un-levelled dyeing results from the ultra low liquor ratio dyeing bath as well as poor dispersion stability under the high temperature. We recommended some leveling agents to improve the leveling behavior of these dyes mentioned above. The milling technology should be further developed to achieve the dispersion stability.

The adsorption behaviors of acid dye and disperse dye on silk and nylon fabrics were examined, in one bath dyeing system on silk/nylon blend fabric with disperse dyes and acid dyes. In the dyeing of nylon fabric with C. I. Disperse Red 19 (Red 19) and C. I. Disperse Red 60 (Red 60), dye uptake of Red 19 was higher than that of Red 60. When silk/nylon blend fabric was dyed with Red 19 and Red 0, the dye uptake on nylon was influenced by the ffinity of the dye to the silk fabric. In the dyeing of silk/nylon with C. I. Acid Blue 80 and C. I. Acid Yellow 121, solid shade could not be obtained with the conventional method but could be obtained with the dyeing resist agent for nylon. There was not any relationship between K/S value and Munsell value, but Munsell value tended to change with the K/S value.

In this article, effect of the dyeing and mechanical properties were investigated on the polyester ultramicro fiber(UMF) and knitted fabric varying fiber fineness(0.01d and 0.05d). By a treatment with NaOH solution, sea-ingredient was removed and polyester micro-fiber was revealed. The dyeing, build-up and fastness properties of the fiber and fabrics were observed. We used C.I. Disperse Red 60 and Blue 56 for dyeing property and eight Lumacron dyes for build-up property and colorfastness. At low temperature dyeing($100^{\circ}C$), the dyeing rate of 0.01d-polyester UME increased more than that of 0.05d-polyester UMF with Disperse Red 60 and Blue 56 whereas dyeing rate of 0.05d-polyester UMF were increased more than that of 0.01d-polyester UMF at high temperature($120^{\circ}C$), The colorfastnesses of the 0.05d-fiber knitted fabric such as washing, rubbing and light was higher than those of the 0.01d-fiber knitted fabric.

Following the reported study that showed the dyeability of diamino-anthraquinoid blue dyes substituted with relatively shorter alkyl groups, the longer aliphatic substituents than pentyl group were examined in terms of the color strength and fastness properties toward UHMWPE fibers. The color strength was increased up to pentyl group and then gradually decreased. However, the fastness properties were improved continuously to octyl group which was the longest alkyl substituent in this study. The most effective maximum color strength was obtained at $130^{\circ}C$ for 2 hours with 3% owf of dyes. The overall fastnesses to washing, rubbing, and light were good enough for practical uses.

As a subsequent research of the previously reported$^{9)}$, a series of diaminoanthraquinoid blue dyes having hexyl, heptyl and octyl substituents were newly synthesized in order to investigate dyeability toward polypropylene fibers. As the length of alkyl groups introduced to the chromophore increased, the dyeability of the dyes toward polypropylene fibers also increased and then gradually decreased. From the result of dyeing, the hexyl-substituted dye showed the highest color strength and deep shade on pure polypropylene fibers. The good fastness rates to wash, rubbing and light were also obtained for all of the synthesized dyes.

A series of monoazo disperse dyes based on 2-amino-4-phenylthiazole was prepared using various N,N-dialkvlaniline derivatives as the coupling component. The dyes were characterized by IR spectral studies, visible absorption spectroscopy and elemental analysis. The dyeing performance of these dyes was assessed on cellulose triacetate and nylon fibers. These dyes were found to give a wide range of colour shades varying from bright red to royal blue with very good depth, brightness and levelness on fibers. The dyed fibers showed good to very good light fastness and very good to excellent fastness to washing, perspiration, rubbing and sublimation. The dyebath exhaustion and fixation on the fibers were found to be very good.

In order to obtain tasic information for solvent dyeing, polyethylene terephthalate (PET) films was pretreated with water, tetrachloroethylene (TCE) and water/TCE emulsion for three hours at $140^{\circ}C$ for stabilizing the substrate. By film roll cyliderical method, Disperse Red 60, Disperse Yellow 42, and Disperse Blue 27 were diffused in the films and examined dyeing properties. The results are summarized as follows; 1) Diffusion coefficient increases in the order, waterTCE>water/TCE 2) A linear relationship between diffusion coefficient and shrinkage was Observed 3) The temperature dependence of the diffusion coefficient can't be expressed by WLF equation.

For decolorization of synthetic dyes, Isolate fungi were investigated for the decolorization of 8 industrial dyes. One fungus isolated from textile wastewater collected from Banweol industrial complex, Korea showed excellent ability for removing synthetic dyes. Internal Transcribed Spacers (ITS) sequencing result was confirmed as the new Basidomycetes species. HUE05-1 The optimal decolorizaton conditions were pH5, 30$^{\circ}C$ and aerobic condition. HUE05-1 was completely decolorized all dyes in both solid and liquid condition. The result is decolorization effect at Reactive Orange 16; 97.12%, Reactive Blue 19; 92.09%, Reactive Blue 49; 97.04%, Reactive Yellow 145; 95.53%, Acid Orange 10; 99.18%, Acid Violet 43; 98.73%, Acid Blue 350; 94.71%, Disperse Blue 106; 90.07%.
