As an important part of the new material industry, industrial textiles have become a strategic support force for medical and health care, safety protection, environmental protection, infrastructure construction, new energy, aerospace, national defense and other industries.

"Industrial textiles have a wide range of applications, active scientific and technological innovation, and huge development potential, which is the key to the steady growth of the textile industry to expand domestic demand." Recently held in China industrial textile industry's first science and technology conference, Ministry of Industry and Information Technology Department of consumer goods industry inspector Cao Xuejun said.

Breakthroughs in key core technologies

Industrial textiles are the main direction of global textile science and technology innovation. Around the "bottleneck" problem, the key core technologies need to be broken through.

Three-dimensional weaving technology is a kind of high-tech textile technology, which has great potential in the fields of national defense and people's livelihood. Sun Yize, director of Textile Science and Technology Innovation Center of Donghua University, professor and doctoral supervisor of School of Mechanics of Donghua University, focuses on the research of this technology. He said that three-dimensional weaving technology has the advantages of high interlayer strength, large damage tolerance, near-clean forming and integrated weaving.

"At present, our team is continuously working on technology to meet the nation's significant demand for high performance fiber composites." Sun Yize said.

With the accelerated integration of 5G, industrial Internet and other new technologies with the manufacturing industry, the digital economy is advancing to a richer form and higher level, providing more means and tools for the upgrading of manufacturing capacity and business model innovation of industrial textiles. 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 engaged in the research of intelligent sensors, bionic intelligent interface sensing, intelligent micro nanomotors, fluorescent gold cluster sensing and detection.

Zhang Xueji introduced that intelligent wearable biosensor technology is to transform invisible human physiological characteristics into visible physical and chemical signals through the research and development of comprehensive intelligent sensing system integration, high data link transmission and interconnection, artificial intelligence decision-making and collaboration, and ultra-high performance impact resistant protection system, so as to change human life and create digital life.

"In the future, we will focus on promoting the development and application of advanced equipment and intelligent construction in the field of nonwovens, continue to carry out intelligent manufacturing pilot demonstration and industrial Internet platform demonstration in the industry, and further increase the research, development, application and promotion of intelligent textiles." Li Lingshen, vice president of China Textile Industry Council suggested.

Expand new application space

With the deepening of scientific and technological innovation, the industrial textile industry is also constantly expanding new application space. Many enterprises have set their sights on medical treatment and health, rail transit vehicles and other application fields.

Song Haibo, R&D Director of Steady Medical Supplies Co., LTD., said, "We started from cotton breeding and gene editing, centered on the ultimate material innovation of cotton, and created six categories of infection control, high-end dressing, traditional dressing, respiratory protection, adult care and home care, such as: New natural environmental protection biodegradable masks and cotton three-resistance operating clothes, functional antibacterial fabrics, unique yarn technology, cotton and fixed spinning, as well as cotton spunlaced non-woven fabric, cotton yarn fabric, cotton fiber modification and other innovative results, from the medical professional market to the mass consumer market, to provide a full range of health solutions."

CRRC Tangshan Locomotive & Rolling Stock Co., Ltd. applies the diversified, multi-layered and multi-functional composite materials to the rail vehicles. According to CRRC Tangshan Rolling Stock Co., LTD., CRRC expert Wu Juanjuan introduced, "Taking carbon fiber composite materials as an example, the next generation of subway car body developed by CRRC Group, using carbon fiber composite materials, the weight of the whole car is 30% less than similar subway metal; The use of carbon fiber composite in the new-generation maglev train body reaches 70 percent, and its weight is 30 percent less than that of 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 are mutually restricted, and a balanced comprehensive evaluation is needed. Only by integrating various new materials, new structures and new processes into daily design and constantly making innovations can the development needs of new rail vehicles be met.

Building regional innovation centers

At present, a new round of scientific and technological revolution and industrial transformation are advancing rapidly. The new scientific and technological innovation and industrial paradigm transformation also provide a historic opportunity for the industrial textile industry to "change lanes and overtake vehicles" and embed in the global industrial chain.

Faced with problems such as weak strategic basic ability and insufficient breakthrough of key generic technologies in industrial textile industry, many provinces and cities combined with their own industrial development status, focus on creating new innovation platforms, building regional innovation centers, and driving the industry to "break through".

Zhejiang Province has set up the modern textile Technology Innovation Center, which is based in Zhejiang and facing the whole country, and provides support for Zhejiang to become the world's important scientific and technological innovation center and the world's advanced manufacturing base. Qi Dongming, deputy director of Zhejiang Modern Textile Technology Innovation Center, modern textile technology innovation center is one of the four world-class advanced manufacturing clusters in Zhejiang 415 advanced manufacturing cluster system. The team focuses on four aspects: advanced preparation of fiber materials, high-end textile and ecological dyeing and finishing, intelligent textile manufacturing and advanced composite materials, and future textile technology.

Qi Dongming revealed that in the future, the center will build an innovation platform with strong public welfare attributes, introduce leading enterprises in subdivided fields, cooperate with the upstream and downstream of the industrial chain, explore a new mode of self-hematopoitic function, and enable high-quality development of the whole modern textile industry chain.

Focusing on the forefront of industrial development, Shanghai established the Shanghai Advanced Technology Textile Manufacturing Innovation Center. It is understood that the center focuses on China's aerospace military safety textile, environmental protection and energy saving governance textile, medical and health textile, new energy vehicle textile and other "bottleneck" technical problems, focusing on the construction of 1 public technical service platform, 1 engineering technology research center, 2 pilot test bases, 5 key laboratories. Eight technological breakthroughs have been made in the fields of interior decoration engineering of new energy vehicles, pilot test technology of biodegradable industrial textile materials, pilot test technology of three-dimensional super-large distance flexible composite materials, and functional integration technology of medical protective textiles.

"In the medium and long term, the center will form a technical system of acoustic materials for the interior of new energy vehicles, break through key technologies of green degradable nonwoven fiber materials, key technologies of three-dimensional oversized flexible composite materials, and key technologies of high-strength chemical, flame retardant and anti-static multifunctional protective materials, and complete 8 pilot test verification and industrialization results." Wang Xiaofeng, general manager of Oriental Guochuang Advanced Textile Innovation Center Co., LTD.
