“At present, our team is continuing to carry out technical research to continuously meet the country’s major demand for high-performance fiber composites.” Sun Yize said.
With the accelerated integration of new technologies such as 5G and industrial Internet with the manufacturing industry, the digital economy is advancing to richer forms and higher levels, providing more means for industrial textile manufacturing capacity upgrades and business model innovation and tools. Zhang Xueji, vice president of Shenzhen University, academician of the American Academy of Medical and Biological Engineering, academician of the Russian Academy of Engineering, and academician of the European Academy of Sciences, leads a team that is engaged in research on smart sensors, bionic intelligent interface sensing, smart micro-nano motors, and fluorescent gold cluster sensing and detection.
Zhang Xueji introduced that smart wearable biosensing technology is through the development of all-round intelligent sensing system integration, high data link transmission and interconnection, artificial intelligence decision-making and collaboration, and ultra-high-performance impact-resistant protection systems. The physiological characteristics of the human body are converted into visible physical and chemical signals, thereby changing human life and creating digital life.
“In the future, we must focus on promoting the development and application of advanced equipment and intelligentization in the field of nonwovens Construction, continue to carry out intelligent manufacturing pilot demonstrations and industrial Internet platform demonstrations within the industry, and at the same time further increase the research, development, application and promotion of intelligent textiles.” ChinaTextile Industry Federation Vice President Li Lingshen suggested.
Expand new application space
With the deepening of scientific and technological innovation, the industrial textile industry is also constantly expanding new application spaces, and many companies have set their sights on application fields such as medical and health, rail transit vehicles, etc.
Song Haibo, R&D Director of Wenwen Medical Products Co., Ltd., said, “We started with cotton breeding and gene editing, and focused on the ultimate material innovation of a cotton flower to create infection control, high-end dressings, traditional dressings, respiratory protection, adult care, Six major product categories of home care, such as: new natural environmental protection biodegradable masks and cotton three-antibody surgical gowns, functional Antibacterial fabrics, original yarn technology, cotton and custom-spun yarns, as well as 100% cotton spunlacenon-woven fabrics, 100%cotton yarn font>Innovative achievements such as cloth and cotton fiber modification provide a full range of health solutions from the medical professional market to the mass consumer market.”
CRRC Tangshan Locomotive and Rolling Stock Co., Ltd. uses diverse, multi-layered and multi-functional composite materials in rail vehicles. According to Wu Juanjuan, CRRC expert at CRRC Tangshan Locomotive and Rolling Stock Co., Ltd., “Take carbon fiber composite materials as an example. The next-generation subway car body developed by CRRC Group uses all carbon fiber composite materials. Materials, the entire vehicle is 30% lighter than similar subway metals; the use rate of carbon fiber composite materials in the new generation maglev train body reaches 70%, and its weight is reduced by 30% compared with the traditional aluminum alloy body.”
Wu Juanjuan said that the application of fiber composite materials in rail transit vehicles is an inevitable trend, but the key technologies and performance parameters restrict each other and require a balanced and comprehensive evaluation. Only by integrating various new materials, new structures, and new processes into daily life In design, only by constantly innovating and innovating can we meet the needs of the development of new rail vehicles.
Building a regional innovation center
At present, a new round of scientific and technological revolution and industrial transformation are advancing by leaps and bounds. The new scientific and technological innovation and industrial paradigm shift have also provided a historic opportunity for the industrial textile industry to “change lanes and overtake” and integrate into the global industrial chain.
Faced with problems such as weak strategic foundation capabilities and insufficient breakthroughs in key common technologies in the industrial textiles industry, many provinces and cities have combined their own industrial development status.Strive to create a new innovation platform, build a regional innovation center, and drive the industry to “break through.”
Zhejiang Province has established a modern textile technology innovation center, which is based in Zhejiang and oriented to the whole country, providing support for Zhejiang to become an important global scientific and technological innovation center and a global advanced manufacturing base. Qi Dongming, deputy director of the Zhejiang Provincial Modern Textile Technology Innovation Center, introduced that the Modern Textile Technology Innovation Center is one of the four world-class advanced manufacturing clusters in the Zhejiang 415 advanced manufacturing cluster system.
