Development of industry 4.0 based digital textile printing quality control system (dtp alarm)

In this project a novel quality control system at digital textile printing will be developed. Thus, a 1200 dpi level online monitoring system will reduce the printing error rate less than 5 % and the total cost by approx. 25 %.

Recently, the digital textile printing (DTP) is appeared to be the next-generation of printing technology and process and its market is growing rapidly. Through the collaboration between Korea and Germany, a quality control system for continuous DTP process will be developed. The occurence of defects during DTP process can be monitored in real time and controlled for the production of the high quality printing products. Germany and Korea are considered as high-tech nations. With their past and their present performance, both countries stand at the threshold of jointly reaching the pinnacle of science and technology. Therefore, the construction of DTP Alarm presents a great opportunity for a new form of industry-oriented and intercultural collaboration. This project is a collaboration of four participating organizations, consisting of research institutes and enterprises of both countries, Germany and South Korea. Since early 2000, the korean company PyungAn Co. Ltd, Daegu, Korea, has introduced eco-friendly DTP technology and recently developed its own technology which is based on the first high-speed multi-pass DTP equipment. DYETEC Institute, Daegu, Korea is a research institute and holds the core technologies for DTP as the next-generation digital printing technology. DYETEC develops the technologies of DTP in general such as the pretreatment technology for color and design implementation based on the fiber materials and post-treatment technology for enhanced durability. The Ark | group is a young emerging companies group and has in the field of integrative production techniques for engineering numerous solutions and products for the future textile machine. As part of the Ark | group Gemini Business Solutions GmbH, Aachen, Germany, offers not only consulting services around the subject of industry 4.0, but also the necessary software and hardware for the gained solutions. The Institut für Textiltechnik (ITA) belongs to the top 5-institutes of RWTH Aachen University which was awarded by the German Federal Excellence Initiative. Its area of core expertise is the development of textile machinery and components, high performance fiber materials, manufacturing technologies and comprehensive process chains and the development of innovative textile based products. At present, the mass production of digital textile printing was made possible by the advancement of technology and the spread of large-scale machinery. However, the mass production methods by big machines still have a high rate of printing error (7~10%). For example, one of the biggest part of misprints are often caused by clogging of the nozzle during printing at a high speed. In this project a printing error reporting system for digital textile printing is designed to enable the increase of printing productivity. The total cost can be reduced by approx. 25%. The systems to be developed will be equipped, built and tested using an online monitoring system. The DTP-error reporting system will be divided three components: The dependence study of misprints on different textile surfaces and dyes, the image recording system and image analysis with quality database for error documentation. At the conclusion of this project, the system should detect large part of the economically relevant determinated errors and hence assure the quality of digital printed textile products.
