This research aimed at scrutinizing the comparative dyeability of some disperse dyes at low temperature on ultra-microfiber polyester, islands in the sea type (0.05 denier), which has claimed utmost fastness and improved uptake of dyeing. Comparisons of dyeability, such as rate of dyeing and color depth, on ultra-microfiber polyester were evaluated by H.T. exhaust dyeing method and followed by the test of rubbing fastness. To achieve high wet fastness, some commercial disperse dyes, Terasil WW and Megacron dyes, which have been recently launched for excellent wash fastness, have been examined compared with conventional disperse dyes, C.I Disperse Red 167 and C.I Disperse Orange 30.

Parsimon juice dyeing is the one of the most popular natural dyeing methods which have been done traditionally among the farmers. The clothes dyed with parsimon juice has several merits, that is, it become much more durable, cool, easy to wash and wear after dyeing and these merits are the reason why people likes to wear the parsimon juice dyeing clothes as work wear. Especially in Cheju province, parsimon juice clothes became a folk costume and many people still enjoy wearing it in the hot summer days. But one of the demerits of parsimon dyeing is that the possible period of dyeing is very short. So, if parsimon juice dyeing could be done with the preserved parsimon juice, it would be possible to enlength the period. With this idea, we compared the color and colorfastness of fabrics which were dyed with 4 kinds of parsimon juice. The experimental parsimon juice 96-8 was preserved during 13 months, 96-9 was 12 months, 97-8 was 1 month and 97-9 was not preserved one. The experimental fabrics were cotton, silk. nylon and polyester fabrics. The results were as follows ; 1. The colors of fabrics dyed with experimental parsimon juice 96-9, 97-8, 97-9 were yellow-red and dyeing states were good. But the colors of fabrics dyed with 96-8 were dark and the state were bad, because the color of experimental parsimon juice 96-8 was changed during preservation. 2. The best state of dyeing could see in the fabrics dyed with experimental parsimon juice 97-8, although that was preserved 1 month. 3. There were differences of color between experimental fabrics dyed with same juice and the colors were thicker in cotton and silk than in nylon and polyester fabrics. 4. During wetting and drying process, the color changes in fabrics dyed with no preserved one were more than in fabrics dyed with preserved ones. 5. The color fastness to the light of the dyed fabrics was over 4, to the acidic perspiration was 3~4 or 4~5, to the alkaline perspiration was 2, 3 or 3~4 and to the washing was 1~2. There was no significant difference in colorfastness between the 96-9 dyed fabrics and 97-9 dyed fabrics.

This study was performed to investigate the physical and chemical properties of the 5 kinds of fabrics dyed with persimmon juice and undyed fabrics. The difference between dyed and undyed fabrics was checked experimentally. Obtained results are as follows. 1. Bending length and flex stiffness were increased after dyeing, and tensile strength of waif i3l fabrics except Ramie was also increased. 2. Abrasion resistance was improved in Ramie and Hemp after dyeing but the rest of fabrics were decreased. 3. Crease resistance of dyed fabrics was roughly worse than that of undyed fabrics. 4. Air permeability remarkably increased after dyeing and this fact estabilished that the traditional Gal-01 was cool clothing. 5. Water repellency in Cotton 1 and Polyester rises but the rest of fabrics were not changed. Therefore it is found that this repellency related to the their fabric counts. 6. Blocking effect of UV light and visible ray was increased in all dyed fabrics. Especially dyed Cotton 1 and Polyester blocked UV light almost perfectly. 7. The colorfastness to soaping and sunlight was proved to less than 3 grade in all fabrics after dyeing. It indicates that this colorfastness became worse owing to dyeing. 8. The colorfastness to dry cleaning and water was decided to more than 3 grade in all fabrics. 9. The colorfastness of the dyed fabrics to sweat after exposing to man-made acid sweat solution was good so that was decided above 3 grade. However after exposing to man-made alkalic sweat solution it became worse owing to dyeing.

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.

The dyeing of polyester fiber with two different disperse dyes (Disperse Red 60 and Disperse Yellow 54) was carried out using supercritical carbon dioxide ($SCCO_2$) as a dyeing medium at temperatures ranging from $50^{\circ}C$ to $90^{\circ}C$ and at pressures from 15 MPa to 30 MPa. The dye uptake of Disperse Red 60 on polyester fiber was found to increase with temperature at constant pressure and $SCCO_2$ density (700 kg/$m^3$). At $90^{\circ}C$ and 30 MPa, the dye uptake on polyester fiber increased with dyeing time and the saturation concentration of Red 60 was attained within 240 min, while a longer dyeing time was required for Yellow 54 to reach its saturation concentration. When dyestuff mixtures with mixing ratios of 0.01 to 9.0 (Red 60/Yellow 54) were used, the uptake ratio of the two dyes was found to be proportional to 0.26 power of their mixing ratio. Dyed fibers showed an orange color and the depth of the color depended upon the mixing ratio of the dyestuffs.

Plantae of the natural material has been broadly used on cloth dyeing by it's specific properties such as eco-friendly and innoxious. However dyeing with natural material on synthetic fiber is nearly impossible due to poor affinity between natural material and synthetic fiber. The method which is binding with micro-capsulized natural material to cloth, used in this study, has low change on quality by external influence. Also this method has high ability in spray effect by broken capsule which comes to pressure and friction when the treated cloth was dressed. And this method is applicable widely from natural fiber to synthetic fiber. The purpose of this study is to develop the multi-functional synthetic material with micro-capsulized Ginseng on PET. Moreover, it was driven by comparison of colormetric properties and fastness between regular dip-dyeing method and binding with micro-capsulized material method. Dyeability showed a little bit low exhaustion but the PET treated by micro-capsule was more or less better than the dip dyed PET. Through the SEM(Scanning Electron Microscope) of PET treated by micro-capsule, it has good residence of capsules even after 5 or 10 times washing. Wash and light fastness were revealed some different grades by each condition but showed high level, in most and the micro-capsulized PET was more improver than regular dip dyed PET.

In this study, we have investigated properties and behaviors of the indigo vat dyeings on synthetic fibers, namely PET and PTT/Spandex. In addition, indigo vat dyeing conditions such as dyeing temperature, dye concentration and pH were optimized. The finding results show that higher color strengths of indigo dyeings on the two types of applied fibers were obtained at $110^{\circ}C$ and $90^{\circ}C$, respectively. Furthermore, acid leuco dyeings on the fiber substrates using acetic acid and formic acid show higher dye uptake with compared to alkali leuco counterparts.

The seven kinds of polyester fabrics having different fabric characteristics were investigated in terms of their dyeing levelness under various liquor ratios. The levelness was evaluated statistically from color strength obtained at different sections of each piece of dyed fabrics. The color strength data were analyzed using a exponential decay function of 3 parameters, $y=y_0+ae^{-bx}$. The b value of the function was used as a index of sensitiveness of dependence on liquor ratio of levelness. The index, b value, showed a linear proportional relationship to thickness of fabrics. Average unlevelness of dyeings exhibited a inverse proportional relationship to both weight and thickness of fabrics.
