Apparel manufacturers have been struggling to meet the wants and needs of their customers without sacrificing the efficiencies and profits gained through mass production. In order to establish interactive apparel pattern making using CAD at a reasonable cost for customizing clothes, it is essential to employ three-dimensional pattern. In this research, we focus on the development of a clothes measurement system using three-dimensional digitization of the shape of wearing clothes. Moreover we attempt to develop a pattern-remaking system that is three-dimensionally interactive, using measurement data from a given model to provide accurate information for individual pattern design. The three-dimensional measurement data was converted by coordinate column to build cross section line model. We created a human body model with ten control points, and which were capable of being deformed by scaling magnification. A clothes model can be modified interactively and suitably with a body model. Pattern fitted size information from the three dimension shape was created, thus allowing us to simulate clothes pattern fitting for individual body shapes. The following results were obtained; 1.The bodice and sleeve sizes of shirt obtained from three-dimensional measurement data were almost identical to those of the original paper patterns. This fact suggests the potential usefulness of our process. 2. The use of the three-dimensional pattern-remarking system, featuring interactive modeling with a cross section line view and duplication pattern view, could be used to easily accommodate any individuals body requirements. Application of this pattern-remaking system using apparel CAD realizes the automatic customization of clothes and more efficient.Article先進ファイバー工学研究教育拠点研究成果報告書 10: 159-160(2004)research repor

Global communication part 1: the use of apparel CAD technology

Trends needed for improved communication systems, through the development of future computer-aided design technology (CAD) applications, is a theme that has received attention due to its perceived benefits in improving global supply chain efficiencies. This article discusses the developments of both 2D and 3D computer-aided design capabilities, found within global fashion supply chain relationships and environments. Major characteristics identified within the data suggest that CAD/CAM technology appears to be improving; however, evidence also suggest a plateau effect, which is accrediting forced profits towards information technology manufactures, and arguably compromising the industry's competitive advantage. Nevertheless, 2D CAD increases communication speed; whereas 3D human interaction technology is seen to be evolving slowly and questionably with limited success. The article discusses the findings and also presents the issues regarding human interaction; technology education; and individual communication enhancements using technology processes. These are still prevalent topics for the future developments of global strategy and cultural communication amalgamation

Enhancing the employability of fashion students through the use of 3D CAD

The textile and apparel industry has one of the longest and most intricate supply chains within manufacturing. Advancement in technology has facilitated its globalisation, enabling companies to span geographical borders. This has led to new methods of communication using electronic data formats. Throughout the latter part of the 20th Century, 2D CAD technology established itself as an invaluable tool within design and product development. More recently 3D virtual simulation software has made small but significant steps within this market. The technological revolution has opened significant opportunities for those forward thinking companies that are beginning to utilise 3D software. This advanced technology requires designers with unique skill sets. This paper investigates the skills required by fashion graduates from an industry perspective. To reflect current industrial working practices, it is essential for educational establishments to incorporate technologies that will enhance the employability of graduates. This study developed an adapted action research model based on the work of Kurt Lewin, which reviewed the learning and teaching of 3D CAD within higher education. It encompassed the selection of 3D CAD software development, analysis of industry requirements, and the implementation of 3D CAD into the learning and teaching of a selection of fashion students over a three year period. Six interviews were undertaken with industrial design and product development specialists to determine: current working practices, opinions of virtual 3D software and graduate skill requirements. It was found that the companies had similar working practices independent of the software utilised within their product development process. The companies which employed 3D CAD software considered further developments were required before the technology could be fully integrated. Further to this it was concluded that it was beneficial for graduates to be furnished with knowledge of emerging technologies which reflect industry and enhance their employability skills

Apparel manufacturers hue been struggling to meet the wants and needs of their customers without sacrificing the efficiencies and profits gained through mass production. Order-made clothes are ideal one, however it is expensive because the processes involved are far from automatic and complicated. In order to establish interactive apparel pattern making using CAD with reasonable cost for customizing clothes, it is essential to employ three-dimensional pattern. In this research, we focus on the development of clothing measurement systems using three-dimensional digitization of the shape of wearing clothes.

Exploring the Abilities of 3D Printing and its Viability for Consumption in the Fashion Industry

Abstract With the ever-evolving state of today’s technology, designers and retailers in the apparel industry are seeking out new technological methods that have the capacity to revolutionize and individualize their brand, as well as meet consumer needs and preferences. An emerging technology is 3D printing, which utilizes computer-aided technology and a variety of filaments to construct an object. Though 3D printing technology offers the ability for rapid prototyping, a condensed supply chain, and a sustainable additive manufacturing process, there is question as to whether or not consumers are ready for 3D printed clothing to enter their wardrobes. In this creative study, the authors designed a 3D printed garment in order to test whether 3D printers could be used to make wearable clothing of similar characteristics to clothing typically made of fabric. A survey was then conducted on the University of Arkansas campus to measure consumer response to the project garment. Three primary factors were measured: prior exposure and interest in 3D printing, general fashion interest, and aesthetic appeal of the project 3D printed garment. Overall perceptions of the project garment as well as further use of 3D printing for the apparel industry were positive. The ability of this study to create a fully 3D printed garment as well as understand consumer response to 3D printed clothing provides insight into this emerging technology. The results warrant further research into its capabilities for fashion and that the fashion industry could move towards adopting this technology on a wider scale in coming years. The results indicate that a major transformation in ready-to-wear style is feasible and beneficial to the apparel industry because of 3D printing.

Impacts of the Information-technology Revolution on Japanese Manufacturer-supplier Relationships

'Vertical keiretsu', characterized by suppliers' willingness to make customized investments and their long-term relationships with manufacturers, had been recognized as an important source of strength in Japanese industries. Our model predicts that, in contrast to the recent popular argument, the information-technology revolution can strengthen 'vertical keiretsu'. This is because the efficiency of designing customized parts is significantly enhanced if suppliers undertake a substantial level of IT investments such as the introduction of 3D CAD systems, and the customized nature of such investments could reduce the number of potential suppliers. Our interviews with Japanese manufacturers provide a support to this prediction.Customized investment, Information technology, Japanese firm, Vertical Keiretsu, Subcontracting

Implementing Zero Waste Fashion in Apparel Design

The fashion industry is one of the largest contributors to the economy in Indonesia. However, this industry is the producers of both pre-production and post-production waste in large quantities causing environmental pollution. To meet the needs of consumers for fashion products, this industry actively design or renewing the design of apparel, resulting fabric waste from production in significant quantities during the process. Currently, there are varying viewpoints from practitioners and academics who argue that in order to reduce waste, the effort will be optimized when done during the pattern making and cutting process. Since the year 2008, the concept of zero waste fashion design or better known by the acronym ZWFD has been widely studied and practiced by students, academics, and practitioners in the field of fashion that has interest in the issues of waste pre-production and its influence on the environment. ZWFD itself refers to the steps to produce apparel with the minimum waste from fabrics during the pattern making and cutting process. This research aims to examine how the concept of ZWFD can be implemented in the course of design and apparel production. Characteristic of the fabric used in this experiment is first identified in order to deliver the possible way to work with the fabric in a three dimensional form. Furthermore, the experiment process continues until a certain form and and a lowest waste percentage is achieved. The final result of this research is a garment with as much as seven different looks from one key pattern with two different pattern making methods, namely flat pattern cutting and draping.
