Let Color Have Digital "Identity Card" Shanghai University Research Team To Solve The Global Problem Of Textile Industry
Zhang Ruiyun, Professor of the Textile Institute of Donghua University, has injected new kinetic energy into the textile industry with color digitalization technology, helping to upgrade the textile industry intelligently. The project "the key technology and industrialization of textile fabric color digitization" won the two prize in the 2019 National Science and Technology Awards Conference held on 10. China red, Tiffany blue, Starbucks green... These well-known colors have become brand awareness of consumers. For textiles, color is the core element of expressing individuality and fashion culture. Color application, quality control and communication are more closely linked to the value chain of the entire textile. In textile design and production, how to achieve efficient, precise control and digital transmission of fabric color has become a big ball problem.
Color digitalization, as the name suggests, is to use data to give color a globally recognized ID, like the "identity card" of color. Zhang Ruiyun said, do not underestimate the color, although the color is visible, it is very difficult to use the naked eye to completely distinguish, and can not be accurately expressed in language. The same fabric color, different people will have different perception effect. The material and structure of the fabric will also have a great influence on the color of the fabric.
As a big textile country, China produces about 100000000000 tons of textile fabrics per year. But in the development of fabric, the expression of color depends on the experience of factory teachers. The development cycle of fabrics is often seven to eight days due to the need of artificial color matching and physical samples.
Faced with the common problem of textile enterprises, Zhang Ruiyun began to carry out scientific research in the field of fabric color matching and simulation. From 2012 to the present, it has been seven years since the beginning of the drill. Professor Zhang Ruiyun has started exploring the source, and has independently developed the reflectance spectrum system and the high coverage color gamut system of the full spectrum dye, and created a spectral matching model of mixed color and monochromatic, which ensured the high matching of the mixed color sample and the monochromatic fabric.
The innovative color matching technology of yarn and fabric developed by team innovation not only achieves the prediction of fabric color, but also improves the accuracy of color matching at the same time by more than 95%.
The key technology and industrialization of textile fabric color digitalization is a fruitful result of industry university research cooperation. Relying on the advantages of Donghua University's textile discipline, the Zhang Ruiyun team worked together with the world's leading high-grade yarn dyed fabric production company, Lu Tai textile Limited by Share Ltd, to jointly tackle tough points and difficult problems in the production process of textile enterprises, and to strengthen innovation guidance.
Zhang Ruiyun runs around Shanghai and Shandong, and produces first-line research. The data in the laboratory is tested over and over again, and the lights of countless days and nights are always on.
"Mr. Zhang led the team to carry out scientific research work that" paranoid "strength is admirable," Xu Lu, a 2017 grade graduate student in textile materials and textile design at Donghua University, told reporters that behind the big data is boring and complex work. Zhang's rigorous and meticulous learning attitude affects people around him. Under her leadership, the team tackled the technical bottleneck and developed a high performance simulation system with virtual samples instead of physical objects, which solved the consistency problem of color transmission and reappearance of different media fabrics in different places.
Finally, the digital cloud fabric high efficiency cloud platform constructed by the project integrates digitalization, networking and intelligentization. The design and information database with high reduction and high information capacity is used instead of physical objects for storage and transmission. It realizes the opening, sharing and collaborative innovation of the textile upper and lower reaches industrial chain and cross regional production enterprise resources, and realizes the digital transmission of colors between the global production factories and important customers, and promotes the development of the global industrial chain layout of the textile industry.
Speaking of the experience of winning the prize, Zhang Ruiyun classified the winning secret as cross-border. The reporter learned that Zhang Ruiyun was admitted to Donghua University in 1987. When he studied master's degree, he turned his research direction to the direction of clothing CAD. While studying doctorate, his research direction extended to the application of computer graphics and image technology in spinning and weaving. It is this interdisciplinary academic background that opens up a new world of research and exploration for her, so that she can play "digitalization", and hold can get "color". Finally, she has played a unique advantage in capturing the key technology of fabric color digitalization.
"There is no discipline limit in scientific research, and cross border cooperation is needed in the study of intersecting problems in secondary schools, so collaborative innovation can break through." Zhang Ruiyun said.
The breakthroughs in the key technology of textile fabric color digitalization are not only technological innovations in the textile field, but also in the field of textile dyeing and finishing, textile design, computer graphics and image processing and cloud platform technology. The real landing and industrialization of this technology are more important than the promotion and application of enterprises.
From "big" to "strong", the difference between the word "one word" and "China's" in building a textile power dream is bound to play a "technological innovation" card. "The breakthrough of this key technology has made a" strong heart "for the traditional textile industry characterized by labor-intensive and production experience. Zhang Ruiyun said that there is no limit to scientific research. We hope to constantly upgrade and upgrade this technology to speed up the digitalization and intelligentization of China's textile industry, and to" shine "the hard core strength of Chinese textile in the world textile industry.
