Antimony free polyester fiber technology realizes industrial application! National Advanced Functional Fiber Innovation Center Solves Key Technical Problems
On August 3, the front page headline of Wujiang Daily focused on the industrial application of antimony free polyester fiber technology, and the National Advanced Functional Fiber Innovation Center solved key technical problems. On August 3, 2022, the following is the original Wujiang Daily: Recently, a good news came from the pilot test base of the National Advanced Functional Fiber Innovation Center. The antimony free polyester fiber technology developed by the innovation center has been industrialized in Guowang Hi Tech, Xinfengming Group, Hengyi Group and other enterprises. It is reported that the quality of semi dull polyester filament produced by this technology is stable, reaching the domestic leading level, and the economic and social benefits are obvious.

A day ago,Pilot Test Base of National Advanced Functional Fiber Innovation CenterGood news came from the innovation centerAntimony free polyester fiber technologyIt has been industrialized in Guowang Hi Tech, Xinfengming Group, Hengyi Group and other enterprises. It is reported that the quality of semi dull polyester filament produced by this technology is stable, reaching the domestic leading level, and the economic and social benefits are obvious.
As China puts forward the "double carbon" goal and continues to promote the construction of ecological civilization, the requirements for environmental protection are gradually upgraded, and the environmental protection standards of manufacturing industry are increasingly improved. At present, it has become the consensus of domestic polyester industry to limit or reduce the use of antimony catalyst, develop and produce antimony free polyester fiber, and realize the green cycle of textile life cycle.
"Antimony based catalysts are generally used in traditional polyester fiber production, and antimony based catalysts are harmful to the environment. The use of new catalysts, such as titanium based or other systems of catalysts, is environmentally friendly, and it is a general trend to replace antimony based catalysts." Xu Song, general manager of the pilot scale test base of the National Advanced Functional Fiber Innovation Center, introduced that, for this reason, the National Advanced Functional Fiber Innovation Center is committed to achieving engineering integration and demonstration application of antimony free polyester fiber preparation technology, and further promoting the application and popularization of environment-friendly catalyst polyester throughout the industry.
The National Advanced Functional Fiber Innovation Center integrates the technical resources of the shareholder Donghua University, Guowang High Tech, Xinfengming Group, Hengyi Group, etc. to form a research and development team for the project of "titanium catalyst preparation and antimony free polyester melt direct spinning filament technology", aiming at cutting-edge technologies and key common technologies to continue to tackle key problems.
Recently, the R&D team overcame the problem of "antimony free polyester fiber preparation technology", developed and promoted the use of new environment-friendly catalyst system, avoided the pollution problem caused by the use of antimony catalyst, realized the green cycle of the textile life cycle, greatly improved the efficiency, and shortened the research and development cycle of antimony free polyester fiber.
Mei Feng, chairman of Jiangsu New Horizon Advanced Functional Fiber Innovation Center, said that environmental protection is not only a requirement, but also a responsibility in today's actively advocating "carbon peak and carbon neutral". For the polyester industry, although a variety of new environmentally friendly titanium based catalysts have come out, which can solve the technical problem of antimony free fiber preparation, the new titanium based catalysts that can be used on a large scale in industrial plants are almost monopolized by foreign companies, which are not only expensive, but also the relevant application technologies are not yet mature.
"China's polyester production capacity ranks first in the world. It is urgent to break the foreign monopoly and develop titanium catalyst for large-scale industrial production of polyester, so as to develop environment-friendly polyester products." Mei Feng said that it is of great significance to solve the technical bottleneck of the green development of the industry under the background of "dual carbon", ensure the green development of the polyester fiber industry, and improve the competitiveness of China's polyester industry.
Through the development and layout of environment-friendly catalysts, the National Advanced Functional Fiber Innovation Center has continuously overcome key technologies and achieved high efficient and stable catalytic effects for polyester esterification and polycondensation. The environment-friendly titanium catalyst developed can not only fill the domestic blank and replace imported products, but also solve the pollution and health problems caused by heavy metal antimony in polyester fiber from the source, which is of great significance for the green manufacturing of polyester products and the improvement of ecological environment.
At present, the technology of this project has passed the production verification of the large capacity direct spinning unit, and has realized batch production, which is helpful for downstream enterprises to reduce dyeing costs and environmental pollution. with10000Take tons of antimony free polyester products as an example to reduce antimony consumption2Tons, with good economic and social benefits. This technology has independent intellectual property rights and has been granted an invention patent2And passed the appraisal of new technology and new products by Jiangsu Provincial Department of Industry and Information Technology, and the appraisal of science and technology guiding projects by China Textile Industry Federation.
