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.

본 논문에서는 컴퓨터그래픽으로 구현된 인체에 착용되는 의류의 시뮬레이션을 위한 수치해석알고리즘 및 소프트웨어 개발을 수행하였다. 개발된 알고리즘은 수학적으로 elliptical 흑은 비순차적인 성질을 가지는 두 개의 켤레조화함수(conjugate harmonic functions)들을 사용하여, 지나간 시간단계(time step)에서의 견과에 의존하지 않고 매 순간의 역학적 균형만으로 의류에 형성되는 주름의 형태를 표현한다. Global-local 해석기법을 채택하여 global 스케일에서의 전체적인 변형과 local 스케일에서의 부분적인 변형으로 나누었으며, 이 두 가지 스케일에서의 해석 결과가 선형적으로 중첩될 수 있음을 가정하였다. Global 해석에서는 신체 각 부위의 회전이나 평행이동, 뒤틀림 등의 전반적인 변형에 따른 인체와의 접촉점의 변화와 응력을 고려하였다. Local 해석에서는 국소적인 주름의 형상을 얻기 위해 주름의 진폭등고선과 주름의 방향 사이의 직교성을 가정하여 단순화 시켰다. 본 제안 방법은 불연속적으로 변화하는 두 개의 서로 다른 자세에 대해서도 중간단계 해석을 위한 시간증분의 삽입이 불필요하며, 기존의 방식에서 주로 사용되는 시간적분의 방법을 채택하지 않으므로 연산 시간의 절감과 안정성의 향상이 이루어졌다. 임의의 두 자세 사이의 연속 동작을 시뮬레이션 함에 있어서도 두 정지 자세 사이의 움직임을 보간법으로 구현하여 연속적인 의류의 변형을 구현할 수 있었다.

Three-dimensional virtual fitting has become a trending practice in the fashion industry because of its productivity benefits, allowing garments to be virtually worn by avatar models without physical production. This study analyzed the variables influencing clothing pressure in both real and virtual fittings to expand the potential utility of pressure data derived from the latter. For this purpose, six sets of compression garments were created by combining two types of tricot fabrics and three types of reduced-pattern tops, with the clothing for real and virtual fittings having identical dimensions. Focus was directed to analyzing the correlation among clothing pressure, surface area deformation, and the mechanical properties of the fabrics. In real fittings, clothing pressure was influenced by multiple factors, including garment design, pattern reduction ratio, body shape, and fabric properties, consistent with existing knowledge. In virtual fittings, however, only the digital mechanical characteristics of the fabrics significantly influenced clothing pressure. The findings suggest that a more reliable implementation of clothing pressure in virtual fitting programs necessitates an approach that considers the complex structural information of garments.

This study analyzed the present uniform satisfaction, uniform satisfaction followed by physical satisfaction, attitude for uniform, purchase attitude for uniform, satisfaction for design, preference for design, and attitude for uniform alteration behavior by distributing questionnaires to high school girl students in Daejeon City. The results of the study are as follows. The study distributed questionnaires to 319 high school girl students in Daejeon City and analyzed the satisfaction factors for their uniforms. As the result, this study induced four factors. The average value of each factor appeared in order of symbolic satisfaction, management satisfaction, activity satisfaction, and aesthetic satisfaction to show that high school girl students were the most dissatisfactory in aesthetic satisfaction. When the study examined the realities of uniform alteration, it showed that 71.2% of them altered their uniforms. In the alteration of a jacket and a skirt, they altered their jackets shortly and tightly in the mass in the order of: waist measurement, jacket length, breast width, shoulder width, and girth of the chest in a jacket. For a skirt, they altered their skirts tightly as a jacket in the order of: skirt length, waist measurement, and the girth of hip.

This study evaluate the effect of laundering on the deformation of knitted spandex/cotton fabrics compared with that of knitted cotton fabrics. Commercial knitted spandex/cotton and knitted cotton fabrics for T-shits were laundered in a drum-type washing machine and dried in a tumble dryer. Wale spirality, shrinkage, elastic recovery and surface contour of knitted fabrics were investigated under different laundering conditions: washing temperature, presoaking time and washing cycles. Knitted spandex/cotton fabrics had a lower angle of spirality than knitted cotton fabrics. After the first washing cycle, the angles of spirality of all the fabrics had decreased greatly. Knitted cotton fabric of low density deformed more than that of higher density. Knitted spandex/cotton. fabric of low density shrank less, because of the greater extension given during heat-set. Permanent elongation length at the 80$\%$ extension was longer than at the 50$\%$ extension, and the knitted spandex/cotton fabric which was expanded greatly during heat-set had a lower elastic recovery rate. The surface appearance of the knitted spandex/cotton fabrics was worsl~ than that of the knitted cotton fabrics before laundering and after repeated laundering, because of the much protruded cotton fibers from the yarns.

The objective of this study was to investigate electrical conductivity of fabrics from polyester (PET) and Nylon (N) containing polyurethane (PU), with silver paste patterns screen-stenciled in three directions. The PET/PU and N/PU fabrics knitted or woven were uniaxially strain-recovered up to 22.5% in three times when each change in electrical resistance was simultaneously measured. This study established four variables that complexly affected electrical conductivity of these specimens; fabric structures, components, cover factors, and the percolation of silver particles. The woven or knitted fabric structures did not distinctively cause the changes in electrical resistance, however, the woven fabrics with the diagonal patterns showed their relatively high electrical resistance. The PET/PU fabrics with increasing the PET proportion generally presented the opposite propensity to its electrical conductivity. The changes in electric resistance of the PET/PU 85/15 2/1 twill and double plain fabrics instantaneously responded to the rate of elongation. The PET/PU group exhibited a reverse correlation between its cover factor and electrical resistivity. The highest electrical conductivity of the PET/PU 95/5 interlock fabric, with very few fluctuations, was attributed to the deep percolation of the silver particles that bridged the gaps between one loop and another. On the other hand, the occurrence of the silver cracks along with the elongated direction led to the immeasurably high change in electrical resistance as the strain increased.

The purpose of this study is to investigate the consumer's complaints for clothing products in quality, uses and care. The consumer's complaints that were lodged to in consumer's claim center, Taejon Housewives Classes, from 1997 Jan. to 1999 Mar. were analyzed. The major results were as follows. 1. Complainers are generally females in their thirties and forties. Out of the clothing items, jackets and jumpers are the most part. Periods of uses and prices of accused clothing are less than one year and one hundred thousands won respectively. For claims about purchasing places, department store ranked first. 2. The complaints are mostly claims related to quality of clothing products, for example damage, color change, deformation, pilling and shrinkage. 3. Concerning the results of claim consideration, responsibility's whereabouts is that consumers, manufacturers, launderer rank in order.

Girls' school uniform evaluative criteria and their uniform modification were investigated. The data were collected by questionnaire from 579 middle and high school girls living in Incheon during the fall of 2003. The uniform evaluative criteria consisted of five dimensions: aesthetics, comfort, economy, management, and status concealment factor. The uniform evaluative criteria were used to cluster the students into five groups: economic, practical, aesthetic, negative, and active. The uniform modifications were investigated in regard to sleeve length, sleeve width, breast width, jacket length, skirt length, hip width, and waist width. The aesthetic and the active groups intended to modify uniforms less in sleeve length and skirt length than the other three groups. There were significant differences in the uniform modifications among demographics: school years, height, weight, spending money, satisfaction/dissatisfaction with spending money, and clothing expenditures.
