This study helps develop cool-touch functional dance sportswear. We suggest a draft design for dance sportswear that chooses appropriate cool-touch functional materials based on an investigation of the changes of body surface temperature before and after exercise, the physical properties of cool-touch materials on the market, and the preference for cooling tools. The results are as follows. First, cool-touch functional sportswear products on the market utilize materials such as PCM, Delta fabric, high gauge fabric, and ice chips as well as incorporate functions such as UV block and eyelets for enhanced breathability. Polyester and polyurethane fibers are mainly used for cool-touch functional sportswear. Second, the neck area showed the highest surface temperatures (32.7℃ and 32.1℃) before and after exercise. Body surface temperatures measured after exercise were also lower than temperatures measured before exercise when wearing dance sportswear. Third, as for the physical properties of cool-touch materials, material 1 showed amaximum drying speed (130 min), material 3 the best moisture absorption speed (122 × 132 min), and material 4 the best thermal conductivity (0.013 7 w/m·K). Fourth, a draft design for a cool-touch functional dance sportswear was suggested, including a neckband made of removable soft PVC material on the neck area and applying material 4 in F1, B4, S2 and lower arm areas and material 1 in the armpit area. Deodorant tape was also attached to the armpit area for added comfort and antibacterial deodorant effect.

Due to the nature of fashion design that responds quickly and sensitively to changes, accurate forecasting for upcoming fashion trends is an important factor in the performance of fashion product planning. This study analyzed the major phenomena of fashion trends by introducing text mining and a big data analysis method. The research questions were as follows. What is the key term of the 2010SS~2019FW fashion trend? What are the terms that are highly relevant to the key trend term by year? Which terms relevant to the key trend term has shown high frequency in news articles during the same period? Data were collected through the 2010SS~2019FW Pre-Trend data from the leading trend information company in Korea and 45,038 articles searched by "fashion+material" from the News Big Data System. Frequency, correlation coefficient, coefficient of variation and mapping were performed using R-3.5.1. Results showed that the fashion trend information were reflected in the consumer market. The term with the highest frequency in 2010SS~2019FW fashion trend information was material. In trend information, the terms most relevant to material were comfort, compact, look, casual, blend, functional, cotton, processing, metal and functional by year. In the news article, functional, comfort, sports, leather, casual, eco-friendly, classic, padding, culture, and high-quality showed the high frequency. Functional was the only fashion material term derived every year for 10 years. This study helps expand the scope and methods of fashion design research as well as improves the information analysis and forecasting capabilities of the fashion industry.

The purpose of this study is to analyze the differences in color, pattern, and texture of functional materials of outdoor clothing according to new senior women's psychological comfort. The data were collected from 163 female respondents aged 55-64 living in Busan. The results of the study are as follows. First, both the high and low psychological comfort groups preferred soft material the most. The high psychological comfort group particularly preferred soft textures and highly evaluated textured material in general. Second, both groups mostly preferred plain patterns while the high psychological comfort group preferred the dot pattern more. Third, in terms of colors, the high psychological comfort group preferred navy and purple, while the low psychological comfort group preferred brown. As to achromatic colors, both groups preferred black the most with the high psychological comfort group preferred gray and white more than the other group. Fourth, the high psychological comfort group preferred colors and patterns of clothing that made one look the most slimming, while the low psychological comfort group strongly preferred colors and patterns of clothes. Therefore, our results suggest that new senior women have a strong interest in outdoor clothing, not only in terms of textile functions, but also having interest in textile designs. In particular, the new silver women value psychological comfort in colors more than patterns of textile design.

Now in the 21st century, all the industries in our world are rapidly changing, including fashion trends and customers' needs as well. Fashion textile planning is also developing towards the direction where it could satisfy the merged sensitivity and incentive of the customers through an idea. The purpose of this study is to accentuate the importance of fashion material planning in fitting conventional patterns and eco-benign fabric materials. Accordingly, this study is mainly focused on the reflection of fabric planning characteristics to show tradition containing comfort and naturalness. As mixing with established fabrics and blending with natural/functional fabrics, and conforming to the trend of the seasonal fabric, it has developed a new structure and pattern by changing the basic source of traditional patterns to a computer aided design system. Therefore, four different types of items were basically up-graded by fitting it in with traditional patterns.

The photochromic dyes(spiroxazine) as a susceptible material were synthesized by condensing 1-nitroso-$\beta$-naphthol with piperidine. The melting point of the synthesized spiroxazine dye was 245$^{\circ}C$. Irradiation with ultraviolet light had effect on reversible coloration reaction. The photochromic dye microcapsules were produced by interfacial precipitation method using polyvinylalcohol and ethylcellulose. The average diameter of microcapsules was 5.4$\mu$m. The dyeability and fastness of dyeings of the microcapsule fibers were increased by pretreatment of the cationic agent.

In this study, 12 azo disperse dyes based on phthalimide were synthesized including their precursors. The chemical structures of the dyes and the corresponding precursors were analyzed by the GC-MASS, $^1H$ NMR spectra and elemental analysis. The dyeability on PET, such as step dyeing and build-up properties and color fastness were examined using conventional exhaust dyeing procedures.

In order to introduce new functions onto textile fabrics, nylon and cotton were treated with green tea extracts. And then the anti-oxidant activity of fabrics treated with the extracts was evaluated by Blois method using DPPH ($\alpha$, $\alpha$-diphenyl- $\beta$-picrylhydrazyl). The anti-oxidant activity was exhibited on the textile fabrics treated as well as by the extracts itself. The cotton fabric treated with 10% o.w.f. of extract appeared to have almost 90% of anti-oxidant activity and 95% was obtained for nylon.

Chitin is the most abundant natural amino polysaccharide and is estimated to be produced annually almost as much as cellulose. It has become of great interest not only as an under utilized resource, but also as a new functional material of high potential in various fields. In addition, chitin and chitosan are recommended as suitable functional materials, because these natural polymers have excellent properties such as biocompatibility, biodegradability, non-toxicity and adsorption properties, etc. (omitted)
