Hierarchically porous carbon materials with high nitrogen functionalities are extensively studied as highperformance supercapacitor electrode materials. In this study, nitrogen-doped porous carbon textile (N-PCT) with hierarchical pore structures is prepared as an electrode material for supercapacitors from a waste cotton T-shirt (WCT). Porous carbon textile (PCT) is first prepared from WCT by two-step heat treatment of stabilization and carbonization. The PCT is then nitrogendoped with urea at various concentrations. The obtained N-PCT is found to have multi-modal pore structures with a high specific surface area of 1,299 m2 g−1 and large total pore volume of 1.01 cm3 g−1. The N-PCT-based electrode shows excellent electrochemical performance in a 3-electrode system, such as a specific capacitance of 235 F g−1 at 1 A g−1, excellent cycling stability of 100 % at 5 A g−1 after 1,000 cycles, and a power density of 2,500 W kg−1 at an energy density of 3.593 Wh kg−1. Thus, the prepared N-PCT can be used as an electrode material for supercapacitors.
본 연구는 한국의 대학에 재학하고 있는 한국인 여대생과 중국인 여대생을 대상으로 캐주얼 셔츠 소재의 주관적인 감각과 선호도의 차이를 파악하고자 수행되었다. 춘추용 캐주얼 셔츠의 소재로 시판되는 소재 중에서 섬유조성이 상이한 7가지 종류의 흰색 셔츠 직물을 선정하였다. 캐주얼 셔츠 소재에 대한 주관적 감각 및 촉감 선호도의 평가자는 한국인 여대생과 중국인 여대생으로 40명이었다. 참가자들은 7종 소재를 관찰하고 나서 주관적인 감각과 촉감 선호도에 대한 평가를 설문지를 사용하여 작성하였다. 캐주얼 셔츠 소재의 주관적 감각을 요인분석한 결과, 평활감, 경량감, 유연감, 신축감의 4개 요인으로 분류되었다. 주관적 감각 요인은 소재의 섬유조성별 국적에 따라 부분적으로 유의한 차이를 보였다. 한국인 여대생은 중국인 여대생 보다 면 100% 소재를 더 가볍다고 평가하였고, 폴리에스터 50%/모달 50% 소재와 P100 소재를 더 신축성이 있다고 평가하였으나, 중국인 여대생은 폴리에스터 50%/면 45%/스판덱스 5% 소재를 더 가볍다고 평가하였다. 캐주얼 셔츠 소재의 섬유조성별 촉감 선호도는 국적에 따라 유의한 차이를 보였다. 한국인 여대생은 중국인 여대생에 비해 면 80%/폴리에스터 20% 소재, 폴리에스터 50%/면 45%/스판덱스 5% 소재, 아마 100% 소재를 더 선호하였다. 한편, 캐주얼 셔츠 소재의 주관적 감각 요인이 촉감 선호도에 미치는 영향은 국적에 따른 차이를 보였다. 한국 여대생의 경우, 평활감과 유연감이 캐주얼 셔츠 소재의 촉감 선호도에 긍정 적 영향을 미치는 반면, 중국인 여대생은 평활감, 유연감, 신축감이 촉감 선호도에 긍정적 영향을 미치는 것을 알 수 있었다. 이처럼 캐주얼 셔츠 소재에 대한 주관적 감각 및 촉감 선호도는 한국인 여대생과 중국인 여대생간의 차이를 보였다. 따라서 여대생을 대상으로 캐주얼 셔츠 소재 기획시 이러한 감성의 차이를 반영하는 것이 필요하다.
The purpose of this study is to create a shirt sloper suitable for an elderly male body shape by producing virtual models using a 3D-virtualization program, making a torso prototype using the Yuka CAD system, and employing 3D simulation to virtualize and calibrate the model. First, the following three types of obese dummies are implemented through the CLO 3D program: Type 1 exhibits body fat in the lower body; Type 2 exhibits an obese abdomen; and Type 3 displays a balanced form of obesity. Second, for the design of the shirt pattern, the waist back length (measured value+1), back armhole depth (C/10+12+3+0.5~1.5), front armhole depth (back armhole depth 0~1), front interscye (2C/10‒1+0.5‒0.5), armscye depth (C/10+2+3.5+ 0.5), back interscye (2C/10‒1+1), front chest C (C/4+2.5+1), back chest C (C/4+2.5‒1), front hem C (C/4+2.5+1(+2)), back hem C (C/4+2.5‒1(+2)), cap height (AH/3‒5), and biceps width (Front AH‒1, Back AH‒1) are calculated. Third, the virtual attachment of the shirt pattern is resolved by increasing the front and back armhole depths, and the front and rear wrinkles are improved by adding a back armhole dart. The front hem lift and lateral pull caused by the protrusion of the abdomen are amended by increasing the margin of the chest, waist C, and hip C, with the appearance improved by balanced margin distribution in the front, back, and side panels. The improved retail pattern with an increase in the front armholes C was balanced on the torso plate.
As the population of consumers of outdoor wear expands, there is increasing interest among consumers in trendy lifestyle outdoor. Accordingly, it is essential to develop designs that are drawn from outdoor wear. This can be limited to traditional mountaineering suits, and designs developed from men’s outdoor zip-up T-shirts, which are highly utilized in everyday life, are very important. This study developed the design of a summer zip-up T-shirt for men with both functional and aesthetic qualities. Visual images of foreign brands and domestic outdoor-focused T-shirts from the spring/summer seasons of 2013-2019 were collected to analyze the following modeling elements: silhouettes, details, colors, materials, and prints. In addition, the design concept was derived by analyzing presentations from the global outdoor trade Fairs (2013-2019). To develop a sustainable eco-friendly outdoor summer T-shirt for men, the concept was derived according to three categories: eco-friendly, sportismexpressed active elements of sports, and an outro-concept of urban town wear as an outdoor lifestyle. Thus, a total of 12 styles of design were developed. High utilization of the outdoor wear T-shirts (which are also popular as lifestyle wear), is an important aspect of building a segmented lineup of the slow-growing outdoor wear market and supports expansion of the scope of theoretical research on outdoor wear design.
This study aims to analyze the changes in the mechanical properties of interlock fabrics knitted with three types of fibers (i.e., cotton, wool, and polyester) by bonding fusible interlinings with varying deniers (i.e., 10D, 20D, and 30D) for a 3D virtual try-on system. We experimented with four properties and thicknesses of twelve specimens of interlining bonded knitted fabrics including face fabrics and interlinings. The results showed that the tensile property changed values (i.e., LT increased, and WT and RT decreased) according to the denier of interlinings; however, the change was slight. On the other hand, the bending property increased significantly as the denier of the interlining increased on both the wale and the course. Among shearing properties, the value of G increased as the denier of the interlining increased on both the wale and the weft; however, 2HG decreased. Additionally, changes in the compression property varied according to the fibers and the denier of the interlinings. The thickness of the knitted fabrics increased or decreased slightly by bonding the interlining. based on these results, we conclude that the 3D virtual system users need to reflect these numerical changes of interlock fabrics by bonding interlinings when they perform fitting tasks on the screen to accurately express the to accurately express the manufacturing conditions of the real garment.

This study aims to compare the ease of shirt patterns in the men's wear market that have been constantly developing, and to analyze the fitness and appearance through the 3D virtual try-on system. The study selected three industrial patterns and two educational materials of classic-fit and slim-fit shirts for a total of ten items. The experiments involved virtual wearing, a stress contact point perspective map, and appearance evaluations. First, the ease differed significantly in the chest, waist, and sleeve cap height according to the patterns. Second, based on the stress, contact point, and transparency, there was ease in the order of Nam, D-brand, J-brand, Park, and S-brand in the classic-fit shirts while the order of D-brand, Nam, J-brand, Park, and S-brand resulted in the slim-fit shirts. Third, in the appearance evaluation, higher points resulted in the order of J-brand, Park, S-brand, D-brand, and Nam in both classic-fit and slim-fit. The results showed that proper ease differs greatly by shirt-fit and target age. Also, the shirts with more ease tended to be evaluated less favorably in the appearance evaluation. Based on the results, the study suggests that the proper ease in chest circumference is 18cm for the classic-fit shirts and 6 cm for the slim-fit shirts.
Interest and desire for analogue emotion increased with the dazzling development of digital technology. Especially, as analogue emotion got grafted in the design field, analysis through various expression media is being done. This study seeks to propose design of t-shirt using unique advantage of Hangeul calligraphy that can satisfy the modern flow and pattern design's various expressions. Calligraphy is being used in various fields such as advert, package, logo, movie poster, signboard, graphic design, calligraphy and abstract painting. Formative yet effective in readability and conveying meaning as it's expressed in letters, calligraphy is a field of attention with its contribution in extending the new design area. As a method of the study, altogether 8 pieces of t-shirts were proposed through related preceding research, literary research, co-work with calligraphy author, computer graphic program, and heat transfer. As such, the t-shirt designs which were created by suggesting various design and using traditional materials like calligraphy, can be used as novel and sensual factor, where one can get a glimpse at the potential of development as traditional fashion product.
This study aims to help understanding on design of basic pattern of shirt collars and to suggest schemes to raise completeness of shape by reviewing problems shown in finished products after sewing. From March 2009 to August 2009, 12 patterns for education and firms were collected centering on basic shirt collar form respectively. There are four problems generally raised from a completed shirt collar. In case of overlapping shirt collar on front neck point, the sewing point of shirt collar should be drawn at front neck point of collar band at a distance of about 0.2~0.3cm, and the center front of band and one of bodice should be arranged in a straight line. In case of the problem about right and left length difference of shirt collar, it is raised by closing so the problem was solved by prolonging about 0.2 cm of the center front of left collar. It was evaluated that adjusting notch point when sewing would be more rational solution than solving something on patterns for distance difference problem of shirt collar between right and left part at center front. And a problem about getting loose of front garment between collar band below and the first button was also raised. It was designed 0.2cm cut of collar band. Around basic shirt collar form, above mentioned solutions are applied to the patterns for education and manufacture experimental clothing. So as a result of sensory evaluation, generally good ratings on all items were received.
