The purpose of this study was to find out the effect of color, tone, perceiver's gender on image perception of natural dyeing of cotton and mosi. The experimental materials developed for this study were a set of stimuli and response scale(The 7-point semantic). The stimuli was 20 fabrics manipulated with two kinds of fabrics(cotton, mosi), five colors(red, yellow, blue, green, purple) and two tone variations. The subjects were 412 adults in Daejeon and Kongju. The results were as follows: The perceived image of the stimulus material consisted of 4 dimensions (attractive, conspicuous, hand, weight) colors, tons, materials as well as perceiver's gender affected on some selected image dimensions color affected on the four image dimensions, tone affected on the conspicuous, hand and weight images, materials affected on the attractive and hand image and perceiver's gender affected on the weight image. Interaction effects existed among colors, tons and materials on the conspicuous image. In conclusion the results support gestalt theory in which the sum of the parts is bigger than the whole and design strategies for the Mosi fabrics should be developed on the basis of persuited design image as well as target consumers.

As the development of denim products using new differentiated materials plays an important role regardless of their target age groups, there is an increasing need for the development of premium denim designs for senior women using various materials. As part of the strategy to develop such a design for the senior generation, a market survey was performed regarding commercially available premium denim products in the market, and the current trends in the denim market were researched and analyzed to make use of the results in design development. In addition, a differentiated material, hybrid yarn using conjugated dyeing (HYCD) was applied to use several washing techniques capable of highlighting the unique features of denim clothing. The design of four items including a jacket, vest, capri pants and long pants were suggested. These items were differentiated from other products by emphasizing their details such as stitching and pockets. In light of the current consumer trend to select denim jeans on the basis of their fashion-ability (e.g., silhouette or color) rather than practicality or price, it is considered meaningful to develop high value added, premium jean products for the senior generation using diverse materials and details. At the same time, performing further studies designed to demonstrate the stability and reliability of the developed products through consumers' comparative assessment is required.

In order to investigate the characteristics of the non-biodegradable material, the $BOD_5/COD_{Cr}$ ratio was used. The average ratio of industrial complex's influent wastewater was 2.29~2.96, the effluent ratio was 4.29~19.0. The removal efficiency of $UV_{254}$ by physicochemical treatment was 22.8~94.7% and 5.3~77.2% by biological treatment, respectively. Of the wastewater removal efficiency for each of the items, the $BOD_5$ treatment efficiency was the greatest at 97.3% and the color & TN treatment efficiency was 40~70%. The study of the economical assessment showed that the complex as well as the individual companies spent 722~1,298 won for each ton of treated wastewater. All of the wastewater treatment facilities spent the most money on chemicals needed to treat the wastewater. The total cost for Nylon manufacturing wastewater treatment plant was the greatest while the total cost for cotton manufacturing wastewater treatment plant turned out to the lowest. As respects of removal efficiency and economocal assessment, Polyester A and Cotton manufacturing wastewater treatment plants were better effective than a dyeing industrial complex wastewater treatment plant.

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.
