The dry cleaning effect related to the type of soil and fiber was analyzed using silicone and alcohol-based solvents(ethyl alcohol, isopropyl alcohol, acetone) that are relatively safe for the human body and environment to improve the detergency of hydrophilic soils in dry cleaning system. Based on this analysis, an effective dry cleaning method to be carried out for improving the detergency according to the type of hydrophilic soils. After dry cleaning was performed using 20 types of artificial soiled fabrics consisting of 7 types of fibers and 4 types of hydrophilic soils, the detergency was measured and the results were compared and analyzed by solvents and fiber types. The results are presented as follows; first, the detergency of hydrophilic soils using silicone solvents showed a low rate of detergency. In particular, the tannin soil showed a lower level of detergency compared to the protein soil. Second, the detergency of hydrophilic soils using silicon solvents with dry soap differed in some detergency according to the soil and fiber types. Especially, the detergency of curry soil on cotton fabric showed significant improvement. Third, the protein soil was not removed from dry cleaning using alcohol-based solvents, but the effect of dry cleaning of curry soil on both cotton and polyester fabric was substantially improved. As a result, the elimination of blood soil is more effective in silicon solvents than in alcohol-based solvents. The removal of tannin soils may improve detergency by adding dry soap to silicon solvents or by using alcohol-based solvents as alternative solvents. The use of alternative solvents such as silicon and alcohol solvents can contribute to the environmental improvement of the dry cleaning industry, which uses petroleum-based solvents. It is also expected to provide consumers with the opportunity to choose eco-friendly and efficient dry cleaning methods.

Due to the increase in consumers' interest about well-being, interest in eco-friendly products has been increasing due to the harmful effects of various harmful substances contained in textile products and environmental issues. As a result, natural dyes of less potential risk than synthetic dyes and digital textile printing(DTP) textile products with less environmental pollution are drawing attention. However, due to the lack of evaluation criteria for DTP textile products with natural ink and the nature of many colors are stacked layer by layer for dying, the need for simultaneous analysis is emerging. To evaluate whether the natural dye is derived from natural ingredients, the biocarbon content is analyzed. However, in the case of ink made using natural dyes and DTP textile products using natural ink, it is difficult to analyze the biocarbon content due to the limitation of the presence of a small amount of dye contained therein. In this study, we were shown the possibility of natural derived verification by cross-checking the analytes of natural dyes (Persicaria tinctoria, an indigo dye; Dactylopius coccus, a light red; and Curcum longa L., i.e., turmeric) and natural ink with HPLC-MS/MS. The coefficient of determination was 0.999 or higher, the limit of quantification was 0.647-3.664 ㎍/L and a %RSD of each indicator material was less than 10. Then, the extraction amount of natural dyes for five patterned fabrics was analyzed.

To realize the traceability of sustainable textile products, this study presents a low-carbon process through energy savings in the textile material manufacturing process. Traceability is becoming an important element of Life Cycle Assessment (LCA), which confirms the eco-friendliness of textile products as well as supply chain information. Textile products with complex manufacturing processes require traceability of each step of the process to calculate carbon emissions and power usage. Additionally, an understanding of the characteristics of the product planning-manufacturing-distribution process and an overall understanding of carbon emissions sources are required. Energy use in the textile material manufacturing stage produces the largest amount of carbon dioxide, and the amount of carbon emitted from processes such as dyeing, weaving and knitting can be calculated. Energy saving methods include efficiency improvement and energy recycling, and carbon dioxide emissions can be reduced through waste heat recovery, sensor-based smart systems, and replacement of old facilities. In the dyeing process, which uses a considerable amount of heat energy, LNG, steam can be saved by using "heat exchangers," "condensate management traps," and "tenter exhaust fan controllers." In weaving and knitting processes, which use a considerable amount of electrical energy, about 10- 20% of energy can be saved by using old compressors and motors.

The purpose of this study is to research the similarity and difference of color application in the culture of Korea and Japan. The subject of this research is the costume color of Changgeuk and Kabuki. This survey analyzes Munsell's 3 attributes(Hue, Value, Chroma), tone, and 3D color analysis by extracted color data. And representative color according to Obangsaek is proposed. The results of this study are as follows: 1. High chroma red in Kabuki costume is more used as symbolic color(passion and luxurious) in order to show character's personality than that in Changguek costume. 2. Low chroma YR color(no-dyeing color) in Changgeuk costume much more used because of Korean white robe preference and eco-friendly thinking. But high chroma yellow is restrictive color for symbolic color of emperor in Korea and Japan. 3. Blue is most frequently used in both costumes because blue is encouraging color by the theory of exponents of the five elements doctrine. 4. White in Korean Changguek costume is more used for white robe preference thinking, but black in Kabuki costume is much more used for symbol of power in Japan. The similarity of Korean and Japanese cultural color is to use much Obangsaek, less Ogansaek by the theory of exponents of the five elements doctrine, but the difference of Korean and Japanese cultural color is to use color differently according to preference thinking system.

This study compared the thermal comfort of indoor clothing from Tencel material that is getting higher in demand due to being eco-friendly with superior wettability, with that from Polyester material that despite being most widely used for indoor clothing, rapidly discharges body sweat due to low wettability. The experiments were performed in the two manners, objective evaluation under the conditions of an artificial climate chamber and subjective evaluation of wearing the given clothes at home followed by filling in the questionnaire. Subjects were 8 healthy elderly women in their 60's who spend majority of their time at home rather than in social activities, and comparison was made on skin temperature and humidity inside clothing at exercise and relaxation states under early summer environment. Based on these results, wearing Tencel material clothing maintained cooler temperatures under warm environment rather than when wearing Polyester material clothing, thus enabling activities under more comfortable state. Regarding humidity inside clothing, parts with twofold clothing did not show difference between Tencel and Polyester, but the onefold arm showed lower when wearing Tencel. With this results, Tencel is regarded as more comfortable and nicer than Polyester.

The purpose of this study is to offer basic data on cosmetics by investigating college women's purchasing and use behaviors regarding cosmetics according to their experience with side effects. A questionnaire was administered to 351 college women in the Seoul and Kyoung-in areas. The data were analyzed with SPSS Statistics V22.0 using frequency, ${\chi}^2$-test, and t-test. The results are as follows. First, 72.6% of surveyed women reported experiencing side effects from cosmetics. The largest side effects were acne and boils, and the primary ways of coping with these side effects were discontinuing use and using other products. Second, the group that experienced cosmetics' side effects used brands that were more expensive and eco-friendly than the group without side effects. Third, the group that experienced side effects continued to use the product more than the group without side effects. The primary reason for continued use was efficacy, and the reasons for discontinued use were efficacy and curiosity. Fourth, the side-effects group proactively identified cosmetics ingredients more than the non-side-effects group. Specifically, they checked the major components, the function, and for any hazardous ingredients. Fifth and finally, 98.3% of survey respondents purchased and used functional cosmetics. The group that had experience with side effects used more functional cosmetics than the group without side effects.

In this study, as one of the eco-friendly dyeing methods, indigo, Phellodendron amurense and Caeasapinia sappan were complexed dyed on cotton fabric. For complexed dyeing, the cotton that was pre-dyed 5 times with indigo was dyed 1 ~ 2 times repeatedly with Phellodendron amurense and Caeasapinia sappan. Then the color, tensile strength, density, and color fastness of complexed dyed sample were analyzed and the following analysis results could be obtained. As a result of color difference measurement, the L* value was 22.7 in the sample in which the cotton was dyed 5 times and then the Phellodendron amurense was dyed 1 time, and the K/S value was 15 or higher in all samples. As a result of measuring the strength, cotton fabrics tended to have a slight decrease in tensile strength when complexed dyeing. As a result of measuring the density, the density decreased by 15 ~ 20% in all samples at the warp and increased by 20 ~ 30% in the weft due to the complexed dyeing of cotton fabric. Moreover, the fastness to washing and drycleaning showed good results of 2 ~ 3 or higher, and the light fastness was 4 or higher.
