Blue jeans are finished with stonewashing process to give it optimal softness and color contrast of blue and white. So, Yellowing may well be generated during storage or use and thereby, their appearance may be damaged much. So, this study was aimed at finding the solutions to reduce the yellowing problem caused by residual metals after stonewshing. To this end, sample blue jeans were made to be finished with various methods of wet-treatment and then, be subject to daylight to check their photoyellowing. The results of this test can be summarized as follows; Since the stonewashing process was found to affect the yellowing, the residual metals of stone- washed blue jeans was analyzed. And it was found that it contained such residual metal as Al, Ca, Cu, Ti, Si, K and Zn. In particular, it was conceived that Al was a prime cause affecting the yellowing. Meanwhile, when the blue jeans were treated by the metal ionchelating agent of EDTA-2Na, the residual levels of Al and Ti were reduced by about 50%, while the photoyellolving was lowered by 75%, which is suggesed that EDTA is very effective in preventing the yellowing. On the other hand, when the blue jeans were bleached by the hypochlorite, chlorine remained in blue jean accelerated the yellowing. However, when this blue jean was treated again by the sodium thiosulfate for its dechloridization, the residual of chlorine was reduced, and the yellowing was lowered by about 43%.

This study aims to investigate the differences in blue jean styles and the visual images associated with them. To achieve this, literature reviews, case studies, and surveys were conducted. The results are as follows. 1) Based on previous studies, it was found that the design elements influencing the style of blue jeans and their visual images include waistline position, silhouette, details, decorations, and color. Additionally, differences in the preferences and visual evaluations of Korean and Chinese individuals regarding the style of blue jeans were confirmed. 2) Skinny blue jeans are typically characterized by a high waistline and a length that reaches the ankles, featuring a snug fit with stretchy fabric. Straight blue jeans, on the other hand, usually have a natural or high waistline and cover the instep, with a straight silhouette descending from the thigh to the hem. Bell-bottom blue jeans are primarily high-waisted and cover the instep with a silhouette forming a bell shape from the knee to the hem. 3) Korean and Chinese women in their 20s evaluated skinny, straight, and bell-bottom styles of blue jeans as having a 'casual' image. However, they also associated bell-bottom style blue jeans with 'unique' and 'attractive' images. Interestingly, Korean women described skinny-style blue jeans as making someone look 'youthful', while Chinese women perceived them as 'sophisticated', 'making the waist look thicker', and 'unassuming'. As for straight-style blue jeans, Korean women saw them as 'well-fitting', while Chinese women described them as 'making one appear taller', 'desirable', and 'free-spirited'.

This study addressed an ill-understood issue of a price response model and a monopolistic price interval of fashion goods. The concept of monopolistic price interval introduced by Gutenberg has been rarely applied to the fashion goods, which is known as price sensitive goods. Thus, this study examined the price insensitive zone of the blue jean. The data of 268 respondents were analyzed using Choice-based Conjoint (CBC) analysis and t-test. Considering brand consideration set as a price determinant, we found the presence of monopolistic price interval of the jean. The results obtained from the CBC analysis showed that the bigger the size of brand consideration set, the shorter the monopolistic interval. This implied that the consumer who had a small brand consideration set was more likely to have a longer monopolistic price interval than the one who had a large brand consideration set, since the consumer with a small consideration set tended to value brand itself more than price. Although significant monopolistic price intervals were shown only for the three jean brands out of the seven, to reduce the size of brand consideration set and to increase brand loyalty were found important in maximizing firms'financial profits.
