Research into the ancient dyeing and weaving culture is of critical importance to the fact that they constitute an integral part of the Korean costume. Due to the absence of the originals reflecting ancient costume cultures, it is difficult to figure out what the dyeing and weaving culture was like in ancient times. Because of limited visual materials available from the wall paintings of ancient tombs, studies conducted so far concerning the costume culture for the Goguryeo have focused on visual elements such as shape, structure, and type. As a result, research into ancient Korean dyeing and weaving cultures hasn't been properly made. Thanks to the presence of both some dyeing fabric originals from Goguryeo's neighboring countries and some visual materials like the wall paintings of the Goguryeo, it may be possible to obtain some clues to the dyeing and weaving culture. The dotted Pattern costumes were selected such as Muyongchong, No. 1 Jangcheon Tomb, Gakjeochong, Samsilchong, Ssangyeongchong, Susanri Tomb. According to a book titled ‘Hanwon’, the Goguryeo people manufactured fabrics in such a way that resist-dyed spots produced elaborate patterns over the purple fabric. It can be safely said that such dot patterns were produced by means of dyeing rather than weaving, because identical patterns aren’t well produced by means of painting and embroidery. Considering Goguryeo’s natural features, the dot patterns mentioned in historical literatures are thought to have been produced using animal’s skin. However, there is highest possibility that the dot Patterns were Produced using tie-resist dyeing or wax-resist dyeing techniques. With respect to the dyeing and weaving culture for the Goguryeo, one must refer to neighboring countries’ dyeing and weaving environments, given that the Goguryeo had engaged substantial cultural exchanges with China.

To develope natural dyeing materials from the unused plant materials, we had several dyeing experiments to investigate the optimum conditions of dyeing fabrics with the waste grape juice. Dyeing experiments were done under different dyeing conditions of dyeing time, dyeing temperature, pH and concentration of dyebath and mordants which were treated after dyeing. Experimental fabrics were silk, cotton, ramie and hemp. Color difference(${\Delta}E$) and Munsell's HV/C of the dyed fabrics and color fastness of silk dyed fabrics to dry cleaning, washing, rubbing, perspiration and light were measured. The color differences of dyed experimental fabrics were very slightly increased with dyeing time and the color of dyed silk was light purple and the cotton, ramie and hemp was light red purple. The color differences of dyed experimental fabrics were decreased and the color became lighter with dyeing temperature increased. The color differences of dyed experimental fabrics were decreased and the color changed from light purple to blue with the pH of dyebath increased. The color differences of dyed experimental fabrics were slightly increased with the concentration of dyebath increased. The color of dyed fabric changed with the mordant treatment and were different among the experimental fabrics. On the whole, blue tone increased with the Al and Fe mordant and green tone increased with the Cu mordant. The color fastness of dyed silk fabrics to light, washing (change) and perspiration (change) was bad and color fastness to dry cleaning and rubbing were good.

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.

Aramid fibers have been widely used as the reinforcement for composites due to their high modulus and strength. Nowadays the safety measures is required to improve the personal protection. The dyeing of aramid fibers is considered to be very difficult and their dyeing mechanism is not well illucidated. Therefore, this study is to establish the dyeing & printing technology for aramid fibers. The effects of swelling agent and neutral salt in the dye bath on the obtained colors were studied. Also dyeing method of aramid fibers depending on dyeing temperature and dye concentration were established. Color fastness of the dyed aramid fabric with cationic dyes were acceptable excluding light fastness.

Chestnut trees have been used as a dyeing material, which are grow naturally, are cultivated all the area of Korea. So, there is abundant amount of the materials and they have better colorfastness than other natural dyeing materials. But chestnut husk extract is good at silk and wool fabrics, not cotton fabrics. That's why many methods using chestnut extraction for dyeing are being studied. But most of them depend on treatment method with chemical material which doesn't fit with the aim, using natural materials. Therefore in this research, we used protein pre-treatment method which is dyeing chestnut husk extract after treating at cotton fabrics with bean sap. And we studied the effect of dyeability of chestnut husk extract to cotton fabrics. As a result of pre-treatment of bean sap at cotton fabrics, dyeability was increased. Besides laundering fastness, dry cleaning fastness, perspiration fastness and light fastness were almost increased.

Dyebath used for metal complex dyeing of nylon microfiber was recycled to reduce the overall amounts of metal complex dyeing effluents. Instead of discharging the dyebath after each dyeing cycle, the residual dyebath was analyzed spectrophotometrically and reconstituted to the required concentration of dyes and auxiliaries. Dyebaths were reused eight times and the CIELAB coordinates of dyed samples were measured after each recycling. Color difference($\Delta$E*) between the sample dyed in the fresh bath and that from reused dyebath was maintained below 1.5. The levelness and fastness of dyed fabrics from recycled dyebath were not impaired either. Chromium content of each recycled dyebath was similar to that of the first residual dyebath.

Five temporarily solubilized reactive disperse dyes were synthesized and characterized. They were applied to polyester/cotton blend fabric using one-bath dyeing method without dispersing agent. The dye that has azonaphthalene chro-mophore seemed to not only be exhausted on polyester but also react with cotton. But other dyes were selectively dyed on polyester and showed limited uptake on cotton. Good levelling as well as moderate to good colour fastness was obtained with the dyes on P/C blend fabric.

The aim of study was to suggest a methodology for applying cleaner production technology in dyeing & finishing process of textile materials. To accomplish cleaner production, we performed consulting activity in dyeing factory, which composed of following different procedures. First, we organized consulting team with specialists for dyeing, energy and chemicals, and visited dyeing companies for the purpose of doing basic investigation such as analysis of process, chemicals & effluents, condition of equipment and process flow of products. Environmental aspect of raw materials (dyestuff, chemicals) was assessed by TOC, COD, BOD, and effluent of that was assessed by TOC, COD, BOD, TDS and pH. Second, We find out the problems in dyeing&finishing process from the view point of dyeing process, energy, raw materials and process management by utilizing MB (material balance), LCA(Life Cycle Assessment), EB(Energy Balance). Third, we generated the solutions to achieve optimal process condition by brain storming method, and then implemented the solutions to each process. Finally, we determined their effectiveness after considering the results of repeating trials for the solutions. Cleaner production could be achieved by keeping optimal process conditions, equipment modification, improved production management, and on-site reuse or recycling.
