The pigment extraction of Opuntia ficus-indica has been conducted to develop useful natural dyes in place of synthetic dyes which are suspected to bring serious environmental pollutions. The dyeing ability on wool fabric by addition of ascorbic acid and several mordants were investigated by means of color measurement. In addition, the fastness of washing, perspiration, rubbing, light, dry cleaning, effect on bacterial reduction and UV-B protection were also investigated. From these investigation, it is suggested that the pigment extracted from Opuntia ficus-indica can be used as a source of natural dyes and the obtained result are as follows. 1. Maximum absorption band (${\lambda}max$) of Opuntia ficus-indica extract is 533nm. 2. The wool fabric dyed with Opuntia ficus-indica extract has stable color by the addition of ascorbic acid and is achieved with addition of 0.1% ascorbic acid, 0.5% several mordant, and three repeated dying at $50^{\circ}C$ for 1.5hr. 3. The wash fastness of the dyed wool fabric when it is washed with neutral detergent is more effective than alkaline detergent. The dry cleaning fastness of the dyed wool fabric is more excellent. In addition, the perspiration fastness of the dyed wool fabric is increased by mordanting method. And than the rubbing fastness of the dyed wool fabric is showed excellent under dryness and wetness. Light fastness of the dyed wool fabric, however is showed inferiority. 4. The wool fabric dyed with Opuntia ficus-indica extract is showed effective bacterial reduction and UV-B protection is increased remarkably.

This study was to investigate the natural dyeing materials in domestic, trials to detect new Inula Britannica. An appropriate dyeing condition ;was bath ratio 1:20, 50% (o.w.f.)conc., $80^{\circ}C$, 50min. The K/S values of silk fabric was the most efficient for the pre-mordanting method. The value of dyed fabric was mostly dark, for the mordanting, the chroma was best clear when using the Cr-mordant, color difference was distinct when using the Fe-mordant. The antimicrobiality of Inula Britannica itself appeared as a 6mm halo zone, dyed fabric was excellent with result of over 90% in mordant. In the case of dye fastness, the drycleaning and wet cleaning fastness was excellent, rubbing and perspiration fastness was improved, and light fastness was over level 2.

Functional properties are available with sputtering. But sputtering treatment alone cannot got a good fastness performance to washing, rubbing and light. This research was objected to investigate optimum condition by sputtering on polyester through various processing conditions such as ion current and treatment time, and then various resin treated onto metal coated polyester fabrics in order to increase washing fastness of metal membrane. As the results, the optimum conditions revealed 1500 mA of ion current, 2 min of treatment time in sputter, and suitable resin concentrations were 2% of o.w.s (on the weight of solution) in resin treatment. Therefore, we could get enhanced anti-static effect and flex stiffness as well as washing fastness in sputtered polyester fabric with various resin treatment, for example, melamine and polyurethane.

The polyurethane prepolymers, which were previously synthesized from 2,4-toluene disocyanate(2,4-TDI) and polypropylene glycol(PPG), were chain extended by ethylene diamine or hydroxyl terminated polydimethylsiloxane(HTPMS) having hydroxy group at both ends of the chain, giving polyurethaneurea(PU) and polyurethane containing HTPMS segment(SiPU), respectively. In thermal gravimetric analysis, PU was almost completely degraded at $500^{circ}$ but SiPU showed about 11% residue at the same temperature. Suspension of SiPU and pigment showed more good compatibility than that of PU and pigment. The crocking fastness, migration fastness and solvent wicking were enhanced to 4.5 grades, 4 grades and 4 grades, respectively.

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.

This paper surveys the mordanting and dyeing properties of Sophora japonica L. Appropriate extraction, dyeing and mordanting condition of Sophora japonica L. were determined, and the effect of mordanting method on dye uptake and color fastness of dyed fabric was investigated. The maximum absorbance of Sophora japonica L. solution was 367.6mn, rutin solution was 365.6mn. The color of Sophora japonica L. solution was affected at pH 2 and pH 8~9. The optimum temperature to extract Sophora japonica L. was during 1 hour in 8$0^{\circ}C$. The effective dyeing temperature and time of silk were 10$0^{\circ}C$, 60min. K/S value of dyeing fabrics was increased by pre-mordanting treatment, especially Fe, Sn, Cr. In the case of Sophora japonica L. light fastness was increased by Fe mordanting. Perspiration fastness was better in acidic solution than that in alkaline solution. Fastness to rubbing and dry-cleaning were good in general.

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.

This study investigated the proper dyeing conditions, fastness and functionality of cotton fabrics dyed with Perilla frutescens var. acuta extract. Repeat dyeing, combination dyeing of persimmon juice and fermentation dyeing were conducted as dyeing conditions. It was confirmed that the ΔE and the K/S value of cotton fabrics dyed with Perilla frutescens var. acuta extracts depending on repeat dyeing and combination dyeing slightly increased. Furthermore, the fastness to washing of persimmon combination dyeing and fermentation dyeing was very good. The fastness to rubbing was shown to be above grade 4 in all methods, and the fastness to light was not as good as grade 3 or lower. The persimmon juice dyeing, Perilla frutescens var. acuta extract repeat dyeing 4 times and combination fermentation dyeing showed very good antimicrobial abilities. Thereafter, additional studies are needed to improve the fastness to light and alternatives to further improve the dyeing properties.

In the Previous studies, we reported about the synthesis of poly[3-methylence-3-methylenesodiumbisulfite-bis(4-hydroxypheny)sulfone] (PMSBPS) and their effect on the staining of direct dye on nylon in the dyeing of nylon/cotton union. The results showed that PMSBPS have good staining resist effect on nylon in the dyeing of nylon/cotton union. In this study, the staining resist effects of PMSBPS in varied dyeing process and method were investigated, and the fastness to washing, light, and rubbing of the deed N/C unions was tested. The results are as follows ; 1. In the two bath two step method, the staining of direct dye on nylon was decreased with the concentration of PMSBPS, and the fastness to washing, light, and rubbing of the dyed N/C unions were increased by addition of PMSBPS. 2. In the one bath two step method, optimun concentration of PMSBPS was 4% 0.w.f..
