China Textile Industry Association launch "Textile Light" applied basic research work for seven years. In the past seven years, the research work on key common technologies in the industry has never stopped. What is the status of each project implemented in 2017? What progress has been made? In 2018, how will the work on basic research projects be carried out? This magazine has visited this.
The State Council recently issued the "Several Opinions on Comprehensively Strengthening Basic Scientific Research" to make arrangements for the comprehensive strengthening of basic scientific research. The "Opinions" put forward the principles for comprehensively strengthening basic scientific research. First, follow the laws of science and adhere to the classification and guidance; second, highlight original innovation and promote the development of financing; third, innovate institutional mechanisms to enhance the vitality of innovation; fourth, strengthen collaborative innovation. Expand open cooperation; Fifth, strengthen stability support and optimize input structure.
In order to improve the technological innovation capability of the textile industry and consolidate the foundation of the industry's scientific and technological development, the China Textile Industry Federation started the basic research work of “Textile Light†as early as 2011. The focus of this work is to support research institutes such as universities and research institutes, and to apply basic research in the textile field in cooperation with enterprises, focusing on supporting forward-looking and long-term basic research; the textile frontier of interdisciplinary, fusion and penetration. Technical research; technology to lay the foundation for solving common industry and key technologies.
In the past 7 years, the Textile Light Technology Education Foundation has invested a large amount of money each year in the research of key common technologies in the industry. However, basic research projects must undergo a series of processes such as theoretical research, laboratory simulation, and industrialization practice, in order to finally achieve innovative breakthroughs. The process often takes a long time. Once a breakthrough is made, it will bring about tremendous changes in the application of textile technology.
According to Peng Yanli, director of the Science and Technology Development Department of the China National Textile and Apparel Council, among the 25 projects currently implemented, there are 14 projects due in 2017, and 3 of them have submitted final acceptance reports. A total of 37 invention patents were applied for, 13 were authorized, 66 were included in SCI/EI papers, and 37 were other papers. The task book requirements were well completed, and progress was made in basic theory, key technologies and engineering application research. She commented: "The implementation of the 2017 basic research project is better."
Biodegradable, simulated and other fiber materials achieve high levels of results
With the continuous innovation of new polymer material synthesis and fiber preparation technology, high-performance, functional, bio-based fiber materials have developed rapidly, and their applications have been extended to the fields of medical and health, national defense, transportation, communications and other industries.
The 2017 Fiber Materials Application Basic Research Project has achieved good research results in biodegradable fiber materials and simulation materials. The project “Influence of the aggregation structure of polyglycolide (PGA) fiber on its degradation performanceâ€, starting from the basic research, systematically studied the structural changes of the fiber under certain circumstances. The project for the development of research led by PGA spinning one-step spinning technology, improve product performance, prepare to meet the strength requirements of the PGA suture fiber provides a theoretical basis, provides a theoretical obtain intellectual property rights for the next PGA fiber and suture basis.
The "New Polyester Esters Synthesis and Properties Research" project, based on the advantages and disadvantages of polyester and polyamide two chemical fiber products, starting from the inherent relationship between polymer molecular structure and properties, researching the polymerization process of new polyamide esters to achieve two The advantages of large chemical fiber polymers are complementary. The new polyamide esters and fibers prepared by the research results are suitable for all kinds of fabrics and home textile products, and have exemplary effects on functional fiber development and simulation technology improvement.
Great progress has been made in areas such as medical care, filtration, and structural reinforcement.
Last year, basic research in medical and public health aspects of the textile field, focus on the study of imitation silk fibroin material reconstruction of the oral mucosa and the active nanofiber nerve conduit for nerve repair long-distance area. Among them, the project of “reconstitution of oral mucosa with biomimetic silk fibroin material†innovatively uses salt-formic acid to dissolve silk quickly and efficiently, while retaining the original fibril structure of silk while preserving, and preparing silk fibroin nanofiber with excellent mechanical properties. material. The effect of repairing oral mucosa is comparable to that of clinical human skin and leather, showing good medical application prospects and providing a new solution for oral mucosal defect treatment. The silk protein regeneration process is of great significance for silk application from the traditional textile field to the high-tech field.
The nerve catheter stent has great application potential in nerve repair. The active nanofiber nerve conduit is used in the research project of long-distance nerve repair. The nerve catheter stent with extracellular matrix structure is prepared by electrospinning method. In vivo and in vitro experiments, it was found that conductive polypyrrole materials can better promote nerve repair, and provide a treatment scheme based on conductive polypyrrole material for neural tissue repair from material innovation, which provides structural design for peripheral nerve tissue repair. A new research idea.
In the field of filtration and separation, the research on the preparation, structural regulation and membrane application of polyphenylene sulfide based resin for hollow fiber membranes has achieved the results of pilot tests. The polyphenylene sulfide membrane is a membrane material with good application prospects by high-temperature membrane filtration, acid-base solution and organic solvent filtration, and high-temperature exhaust gas purification or dust removal. In the future, the output value of polyphenylene sulfide membrane separation membrane can reach 1 billion yuan.
In the field of structural reinforcement composites, "Structure and Properties Regulation wave transparent polyimide composite fibers", "Textile flexible composites prepared spherical antenna and the pneumatic movement key technology" made good progress. Wave-transparent composite materials play an important role in the field of modern advanced radomes and radomes. The preparation and key technical project of textile flexible composite spherical mobile gas-filled antenna has established a small trial production line of marine spherical inflatable antenna, which has established theoretical and technical basis for the pilot and industrialization of subsequent products, and guided industrial production.
