At the moment when the domestic and international markets adjust and change, in the face of the serious excess of conventional varieties in the chemical fiber industry for many years, the overall manufacturing situation of new fiber materials is backward, and the call for technological advancement and investment in scientific research at the source of independent innovation is increasing.
[HC360.com] In the current domestic and international market adjustment and change, in the face of the serious excess of conventional varieties in the chemical fiber industry for many years, the new fiber material manufacturing technology is generally backward, the technological progress and the call for increasing the investment in independent innovation sources are growing. . "In response to the current situation, it is necessary to overcome difficulties and upgrade the level. The new prosperity depends on innovation." Zheng Zhiyi, president of the China Chemical Fiber Association, called for a new seminar on the development and application of fiber materials.
In this context, the seminar on the development and application of new fiber materials gives the industry an inspiration to grasp the direction of innovation from the source. From the Georgia Institute of Technology, Clemson University, New Jersey Institute of Technology and China's Donghua University, Tianjin University of Technology, China Chemical Fiber Industry Association, National Natural Science Foundation, China Environmental Protection Industry Association, many domestic and foreign fiber materials Famous experts and scholars shared and exchanged experiences in new technologies, new processes, new product development, engineering and industrial applications in the field of new fiber materials.
Accelerating the transformation of scientific and technological achievements "The profit of DuPont Kevlar and other high-performance fibers in 2008 exceeded RMB 6 billion, which is higher than the total profit of our entire chemical fiber industry." Zhao Qiang, president of the China Textile Science Research Institute, said in the seminar. As a major chemical fiber producer, China is indeed facing a severe situation in the field of high-tech fiber research and development.
"At present, to adjust the product structure and industrial structure, it is necessary to eliminate backwardness and independent innovation." Zheng Zhiyi pointed out. The combination of production, study and research will promote the industrialization and application of high-tech fiber and accelerate the industrialization of bio-source fiber materials. As a breakthrough point, it will bring about deep adjustment and transformation of the industry.
Successful experience at home and abroad shows that engineering technology development is the key to the industrialization of scientific and technological achievements. The advantages and disadvantages of the possession, allocation, development and utilization of resources are the key to determining the strength of a country's scientific and technological innovation. The construction and operation of an engineering technology innovation service platform that serves the technological advancement needs of the chemical fiber industry is difficult for a single chemical fiber enterprise to support. Therefore, integrating system resources and establishing a sharing mechanism can promote the independent innovation capability of SMEs and achieve common progress in the industry. Zhao Qiang believes that the establishment of the fiber material engineering technology innovation service platform by the China Textile Science Research Institute is the need to accelerate the industrialization of scientific and technological achievements.
Focus on the frontier of science and technology development. Experts and scholars from various countries and various fields have synthesized and prepared new fiber materials such as cellulose fiber and spider silk bionic fiber. On-line detection of melt spinning process parameters, fiber structure and morphology, polyphenylene sulfide Research progress in the application of high performance fiber and hollow fiber membrane composites for filtration such as ether, flow stretching of high performance material preparation, and application of computer simulation in fiber material development have been studied and discussed.
Bionic fiber has always been the focus of modern high-tech fiber development. Dr. Michael Ellison, a professor from the School of Materials Science and Engineering at Clemensons University in the United States, used spider silk as an example to introduce the research strategy of biomimetic preparation of new materials, describing the synthesis of spider silk proteins, the formation of spider silk and the structure-performance. relationship.
Dr. Youjiang Wang from the Institute of Polymer Textile Fiber Engineering, Georgia Institute of Technology, USA, introduced the method of preparing high-hollow PET fibers by using super-stretching technology, and discussed the mechanism of super-stretching with the experimental results.
Professor Dong Jianhua of the National Natural Science Foundation of China introduced how to discover and solve scientific problems in the development of fiber materials. He analyzed the performance of spider silk and the key issues in the process research process, and introduced the research frontiers and research results of high performance fiber, such as nano cellulose fiber performance, process research and application.
Dr. Michael Jaffe from the Department of Biomedical Science, University of Technology, New Jersey, USA, reviews the past of fiber science, analyzes the status quo and looks to the future. Propose the outstanding problems in current fiber science, such as who will be the user of new fiber materials? Who is the authority to identify needs, problems and opportunities in the field? Who will assess the correctness of the solution? Who will pay for the development of new fiber materials? The existence of these problems also provides an opportunity for the development of fiber science. For example, through computer simulation to reduce the risk and cost of research and development, develop sustainable development, renewable materials and high-performance fibers, save energy through the use of lightweight structural materials, prepare new materials through bionics and develop new processing techniques. .
Establishing an innovative service platform The key to independent innovation in the industry lies in the industrialization of scientific research results. The China Textile Science Research Institute has made various efforts in the industrialization of scientific research results, and is in high-performance fiber, functional differential fiber, biological fiber, industry. The success of industrialization with fiber and new generation polyester technology. Polyphenylene sulfide fiber engineering complete technology, ultra-high molecular weight polyethylene fiber dry spinning complete technology, composite conductive fiber, two-component composite fiber, taking filament ultra-high speed spinning combined (FDY) process and equipment, low temperature Breakthroughs have been made in the fields of short-flow tower polyester technology, differential polyester continuous polymerization industrialization technology, and biological fiber development. Some projects have completed engineering technology development and applied to the production process.
As the innovation research base of China Textile Research Institute, the next step is to focus on and support the “Fiber Material Engineering Technology Innovation Service Platform†and the “National Key Laboratory of Bio-source Fiber Manufacturing Technologyâ€. On the basis of resources, we will achieve major engineering and technological breakthroughs, provide innovative technologies and supporting achievements for the industry, and give full play to the functions of the *** innovation research base.
Zhao Qiang said that the China Textile Science Research Institute will be guided by the industry adjustment and revitalization plan, and relying on the “fiber material engineering technology innovation service platformâ€, through the establishment of chemical fiber industry technology innovation strategic alliance, etc., set up an industry-university research and innovation team, Input, risk sharing, benefit sharing, mutual complementarity, cooperation and innovation, and promote the overall technological progress of the textile industry.
