Faculty of Textile Technology Zagreb University

The University of Zagreb, Faculty of Textile Technology has utilized OptiTex software in their graduate studies: Textile Technology and Engineering and Textile and Fashion Design since 2009. Students and professors alike have used OptiTex for teaching and research. S. Petrak Ph.D, who is Assistant Professor and Vice Dean for education at the Faculty of Textile Technology at the University of Zagreb, has included OptiTex technology in his research as well as a core subject in her teaching. 

Currently, there are three courses offered at the Faculty that teach OptiTex technology to their students. These courses can be found in the Department of Clothing Technology and Department of Textile and Clothing Design. Since the University has introduced OptiTex technology into their curriculum, scientific papers that research and analyze OptiTex have been published. From this curriculum, a handful of graduate students are working on their graduate papers analyzing OptiTex technology and focusing on and experimenting with complex research possibilities.

The Faculty of Textile Technology has furthered OptiTex into academic research by publishing several scientific research papers, for example: 

1. Petrak, S.; Mahnic, M.; Rogale, D.; Ujević, D.: Computer Design of Textile and Clothing Collection-Assumption of Contemporary Remote Business, Book of Proceedings of 11th World Textile Conference AUTEX 2011, Mulhouse, France; Ecole Nationale Superieure d Ingenieurs Sud-Alace, June 8th to 10th 2011, 1162-1168, ISBN 978-2-7466-2858-8

 
The importance of time saving in today’s apparel manufacturing context is highlighted. The paper shows what we already know from the real world, how, by using OptiTex; designers no longer have to make several prototypes of the real model/sample because the computer performs all alterations of the pattern. Complex development of the collection of computer prototypes of 3D models of woman's cocktail dresses was performed into variants suitable for different anthropometric body properties and age groups of consumers and in accordance with initial art projects. The entire development was carried out using a 2D/3D CAD system used for interactive design and modeling of 2D patterns and 3D simulation and visualization of garment models applying patterns, textures and colors of fabrics and seams.

Ujević, D.; Petrak, S.; Hrastinski, M.; Mahnic, M.: Development of the garment size system and computer-based body models, ICONTEX 2011 International Congress of Innovative Textiles, Proceedings Oral Presentations, Istanbul, Turkey, The Textile Engineering Department of Namık Kemal University (Çorlu-Tekirdağ,Turkey), October 20^th to 22^th 2011, 219-225, ISBN 978-605-4265-14-5

The paper presents separated results of the anthropometric measurement performed within the scope of the compound technological project (STIRP) "Croatian Anthropometric System" (HAS) in the Republic of Croatia. The presented results apply to adult female population, whereby newly defined female body types taking account of the measurement of hip girth are emphasized.  Based on the presented results the modeling of computer 3D body models for the total of seven defined body types and in all sizes was done in the experimental part of the work. The presentation of limiting, newly defined body types and limiting values for each body type is described. A basis for computer 3D body types suitable for the implementation in the CAD system intended for computer-controlled garment simulation and visualization was created.

The paper shows how, when using OptiTex software, all garment alterations of the pattern are performed by the computer until the optimal fit has been achieved. Finally, garments being developed with this innovative technology can have the quality to compete with the demands of the western markets.

The contribution that OptiTex brings to the academic spectrum of the textile industry is indisputable and the Faculty of Textile Technology study programs looks forward to furthering their research and finding more success in cooperation with the OptiTex development team in the future.
