This study was performed to help the denim fabric planning which reflects the sensibility preference of university students. Objective characteristics, like color properties and mechanical properties, in 8 denim fabrics (5 cotton 100% fabrics and 3 cotton/polyurethane blended fabrics) were evaluated. And the color preference, subjective sensation and tactile preference of denim fabrics were investigated among the university students. The effect of color preference and tactile preference of denim fabrics on the purchase preference of denim slacks was also examined. Color preference of denim fabrics showed a significant difference according to the kind of denim fabrics. University students preferred purple blue denim fabrics that was measured low $-b^*$ value and low $C^*$ value among the color properties of denim fabrics. Among the mechanical properties of denim fabrics, surface property like MMD, MIU and SMD as well as shear property like 2HG5 were important elements affecting subjective sensation. While, tactile preferences showed a significant difference according to the fabrics. The tactile preferences of cotton/polyurethane blended denim fabrics was highly preferred, and that of heavy 100% cotton denim fabric was lowly preferred. And the subjective sensation affecting tactile preferences were in order of smoothness, softness, lightness. It is concluded that the color preference and tactile preference influenced upon the purchase preference of denim slacks, and color preference had a bigger effect upon the purchase preference.

20세기이후의 현대인들의 여러 가지 환경들은 다원화 경향으로 흐르면서 사회, 문화적인 모든 요소들은 많은 변화를 가져오고 있다. 패션에서도 이러한 다원화 경향이 확대됨으로써 기존의 여러 가지 패션요소들이 현대에는 많은 변화를 보이게 되었는데 그중 데님의상의 다양화가 중요한 관심사로 떠오르고 있다 데님의상이 처음 선보였던 19세기 중반에는 원래 노동자들의 작업복으로 출발한 것이었다. (중략)

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.

This study was to investigate the physical properties and the external characteristics of denim fabrics(100% cotton non-spun denim, 98% cotton/2% polyurethane spun denim) such as tensile strength, thickness and weight, flex stiffness, surface color and shrinkage. The results of the study were as follows. After examining the change of external characteristics of before and after washing finishing for denim fabrics, denim with bio washing had increased pliability compared to denim without washing finishing but the pliability of the denim did not increase according to the intensity or frequency of washing. The luminance change according to washing finishing was high in the order of bio stone bleach washing, bio stone washing, bio washing and denim without washing finishing and the surface color became brighter in accordance with the increase of intensity and frequency of washing finishing.

This study explores application of upcycling design methods in structural transformation of second-hand denim clothing, aiming to achieve sustainable design objectives. By drawing inspiration from Liu Qing's research methods in the field of circular utilization of denim clothing, this study collected and analyzed cases of structural transformation of used denim clothing from 2020 to 2023. It summarized structural transformation design methods for used denim clothing. Through the development of design works, this study aims to find out the best upgrading and renovation design strategy by applying the method of structural renovation design. This study aims to support the development of a sustainable fashion industry and promote recycling and upcycling of discarded clothing fabrics, thereby reducing resource waste and environmental impact.

Denim has been one of the most favored clothing item among young people regardless of regional difference. This study compared the styling of women's denim fashion in two Asian metro-cities, Seoul and Beijing, in order to understand how differ the fashion taste of both cities. Data was collected by taking photos of young women who wear denim clothing at the main streets of downtowns or famous shopping areas of both cities from the July of 2004 till the April of 2005. A total of 524 photos(Seoul 242, and Beijing 282) were put into content analysis. Results showed that there were several similarities and differences in denim styling between two cities in terms of the most widely worn denim items and the coordinate items, and the favored colors, silhouette, details of denim pants and the coordinate items. In Seoul, women favored denim look with little detail, fitted silhouette, and in more formal image. A few denim styles prevailed in each season which reflect current denim fashion trends. Meanwhile a wide variety of denim styles were found at Beijing without dominant denim trends, which means Beijing women put more emphasis on personal expression of their fashion taste instead of just following fashion trends.

Denim washing is processed with different washing techniques such as stone washing, chemical washing, sand washing, and bio washing. Cellulase bio washing can meet environmental regulations that enhance and rectify problems associated with traditional decolorization techniques; however, stone washing needs to be added to the processing because it produces a low decolorization effect. There is also the problem of additional strength reduction. To prevent these problems, a new enzyme for bio washing is required. This study examines the optimum laccase treatment conditions on denim and evaluated the characteristics of laccase-treated denims to establish a database of eco-friendly new decolorization process on denim using a new laccase enzyme. The results show that the optimum conditions of laccase on denim are a pH of 4.0, $30^{\circ}C$, 7% (o.w.f.), and 6 hours in 10 mM of buffer concentration. UV absorbance and HPLC identified isatin coexist with anthranilic acid in solution after laccase treatment on denim. Results of the surface color, the surface morphology and the tensile strength indicate that laccase treatment shows an excellent decolorization effect without fiber damage. The wet cleaning fastness and the perspiration fastness also improved.

This paper discussed the assessment of hand of Tencel denim fabrics finished by enzymatic hydrolysis. The subjective hand and the preference of Tencel denim fabrics were evaluated using the developed scale. The factors affecting consumers taste for Tencel denim fabrics were analyzed by statistics using SAS program. Also, the effects of cellulase treatment on the properties of Tencel denim fabrics were evaluated by the subjective hand measurements. The results are as follows: As the weight loss increased. fabrics were evaluated as finer, smoother, softer, warmer, more refined (surface properties), more compact and weaker (durability), more flexible, flossier, lighter, softer, thinner (sense of weight), more elastic, and less wrinkly (shape recovery). Fabrics were evaluated to have the dry touch regardless to the rate of weight loss (moisture properties). Overall hand preference of Tencel denim fabrics was in the side of not preferred. Hand of Tencel fabrics seems not to appeal to Korean people. Color preferences were not significantly different among five groups. The correlations between subjective hand and preference showed that fine, smooth, flexible, warm, refined, loose, soft, dry touches were preferred in Tencel denim fabrics.
