  • Advances in 3D garment simulation technology contribute greatly to consumers becoming more immersed in movies and games by realistically expressing the garments the characters in the movie or game are wearing. The fashion industry has reached a point where it needs to maximize efficiency in production and distribution to go beyond time and space in order to compete on the global market. The processes of design and product development in the fashion industry require countless hours of work and consume vast resources in terms of materials and energy to repeat sample production and assessment. Therefore, the design and product development tools and techniques must aim to reduce the sample making process. Therefore, this study aims to study a case for comparing the real garment sample making process to the virtual garment sample making process. In this study, we have analysed the differences between the real and virtual garment making processes by choosing designated patterns. As we can see from the study results, the real and virtual garments generally are made through similar processes in manufacturing, while the time consumed for each shows great variation. In real garment making, scissoring and sewing require the greatest number of work hours, whereas in virtual garment making, most of the time was spent in the simulation process.

  • Environmentally-friendly whole-cut designs can minimize carbon dioxide emissions which are harmful to the earth, and reduce energy, labor force and time in cutting or sewing clothes. The design and way of wearing clothing will be investigated by classifying whole-cut clothing appearing in the history of costume and past traditional outfits such as Drapery, a Pancho, Tunic, or Loincloth. According to the results from the analysis of whole-cut methods applied in design, they were classified as follows: whole-cut, utilizing square-panels as is, pleats, smoking, lip band, origami, cutting way, and subtraction-cutting whole-cut design. The whole-cut design utilizing square panel as it is can minimize the waste of energy and material but can also maximize the possibility of circulation by recycling. In utilizing an all square panel, it broke away from the existing whole-cut in the western pattern, namely, the pattern of clothes clinging to the body, and was found to have new aesthetic value with a new approach. Due to the whole-cut method having a restriction in the use of dart and line cutting in its designing process, there were only designs that did not show the body line, such as designs clinging to the body. Therefore we developed a design similar to those that cling to the body by whole-cut, In addition, the work produced was with high efficiency and variability, which produces simple designs but can be worn in a variety of ways.

  • The rising demand for fashion do-it-yourself (DIY) products that cater to individual preferences and which allow for creative expression has highlighted the need for systematic organization within the clothing society. This study addresses this gap by identifying and discussing clothing DIY packages and proposes a systematic package model comprising essential raw materials, commercial patterns, and production instructions. Four key elements have been emphasized to differentiate and enhance the product. Firstly, highly practical commercial patterns have been developed to facilitate easy transformations - from blouses to dresses. Furthermore, the versatility of these patterns has been optimized so as to allow their utilization as outerwear, increasing their efficiency. Secondly, to accommodate diverse body shapes, the package offers six different sizes, providing users with a range of options tailored to their specific measurements. Thirdly, detailed production instructions are provided, supplemented by a Q&A bulletin board. The instructions are available in a printed format, featuring actual photographs on A4 paper, while video production instructions are accessible via a QR code, ensuring comprehensive guidance. Lastly, the basic package comprises clothing patterns, production instructions, fabrics, and labels, providing a complete toolkit for clothing DIY enthusiasts.

  • Global sourcing strategy is the one that apparel firms adopt in order to improve efficiency. Souring statesgies are not limited to the decision of sourcing country or vertical integration of sewing process Sourcing strategies include all the ecision of marketing process from the acquisition of fabric to distribution of products. The present study aims to analyze the soucing strategies of Korea apparel industry in global perspectives by applying transaction cost approach and aims to provide the implications for the future. The results are as follows ; (1) sourcing strategies in the dimension of domestic versus offshore soucing are determined by the experience in foreign business and the degree of fashionability of the product. (2) Firms tend to increase affshore soucing as they accumulate the experience in foreign business because they can decrease transaction costs as the perceived risks decrease (3) Also firms tend to source their products in foreign countries when the products are more fashionable. Brand loyalty of the product is a additional factor that increases the proportion of domestic sourcing. (4) Degree of vertical integration of sourcing is determined by the fashionability brand loyalty and the experience in foreign business. That is firms decrease the transaction costs by avoiding the investment to short life fashion products. However firms increase the control over the high reputation product by in house production. As the apparel firms tend to more marketing oriented and the national boundaries of business envrionment becomes permeable more efficient global sourcing strategies should be stablished, Besides the production costs nonproduction costs should be equallly considered in order to analyze the total costs.

  • This study establishes basic data for operations management by organizing processes and measuring time in the mini line for female jackets to improve productivity, ensure competitiveness, and maintain operator competency and the line process flow balance between apparel manufacturing companies. The results of this study are as follows. Sewing operations are divided into preparation functions, arrangement, partial tasks, and assembly that consist of 84 processes. The results from time measurement indicate that 3238.41seconds (sec) were required to produce a single jacket and that the average time required for operators was 231.32 sec. A control limit was established to increase the reliability of the measured value for net time. After outside values were removed, the operation time was measured to be 3176.35 sec. This accounted for 98.08% of the total operation time, with net time decreasing by 62.06. Skill and effort level coefficients were applied to measure the operator performance, the total real time was calculated to be 3415. The requirement for preparation and arrangement operations were 1233.35 sec, and 2182.22 sec for partial tasks and assembly operations. Process separation and organization were performed after the bottleneck operation was selected to identify the maximum line balance. Consequently, process efficiency of preparation and arrangement operations increased from 79.19% to 93.00%, and the partial tasks and assembly operations increased from 62.36% to 90.93%.
