The dynamic tension of the fiber directly affects the physical and chemical properties of the fiber product and its post-processing. However, China has started late on how to accurately measure the dynamic tension and its instrument. Yang Dinghai said in an interview with reporters: "As early as 1985, we began to develop a new large-scale, high-precision dynamic electronic tension meter. At that time, the school's research room was very tight, and my two assistants. Proactively proposed to the leadership to move the research site to the underground air-raid shelter. In this way, we stayed in the air-raid shelter for nearly half a year. The hard work pays off, our research team finally succeeded in the first high-rise in China in the long-term sunshine shelter. Precision large-scale electronic tension measuring instrument." According to the expert appraisal committee, the technical indicators of the instrument have reached or even exceeded the level of similar foreign products. Later, the project won a national utility model invention patent, a national invention patent, the third prize of the former Ministry of Textile Science Progress, and the third prize of Shanghai Science and Technology Progress Award. Last year, the project was also approved as a high-tech achievement transformation project in Shanghai (project level A), and was listed as a national 863 project by the Ministry of Science and Technology. At present, Yang Dinghai and his research team have developed a full range of high-precision electronic tension measuring instruments, which are used by civil and military units, and have been well received by users. They have also won the gold medal for the promotion and implementation of Shanghai's outstanding invention products.
According to Yang Dinghai, how to accurately measure and control fiber length has long plagued China's textile and chemical fiber industries. To this end, Yang Dinghai and his team did not hesitate to undertake the research task. He told reporters that the members of the research team often gave up their Sunday breaks and went to the line factory to design, develop and debug the novel electromechanical integrated electronic line numerical control instrument. After nearly a year of hard work, the design requirements were finally met, and the measurement and control line length accuracy was far superior to the national standard. The expert appraisal committee found that the instrument did solve the bottleneck technology that has plagued the industry for decades of accurate measurement and control line length. The achievement won the national utility model invention patent and the national outstanding invention silver award.
For the development of China's textile industry and polymer industry, in recent years, Yang Dinghai and his research team have worked tirelessly to abandon the rest of the year and continue to innovate independently, and explore and develop in the field of novel measuring instruments in China. A series of scientific research results. For example, the semiconductor refrigeration high-precision thermostats that are commonly needed in the chemical fiber industry they have developed have won the Gold Award for the implementation of Shanghai's outstanding invention products; the trace moisture differential pressure meter for measuring the moisture content of polyester chips has won the second class of Shanghai Excellent Inventions. Award; the new automatic sound velocity orientation measuring instrument for measuring various fiber orientations used by college chemical fiber professional, won the second prize of Shanghai Excellent Invention and so on. This year, Yang Dinghai has successfully developed a new small-angle laser scatterometer, a computer-automatic viscosity measuring instrument, and a novel digital melting point measuring instrument. These instruments have achieved significant brand effects in the domestic textile, chemical fiber industry and polymer industry with excellent performance and price ratio and good after-sales service quality. After being used by famous universities such as Donghua University, Fudan University, Zhejiang University, East China University of Science and Technology, East China Normal University, Zhongshan University, Beijing Fashion Institute, and Tianjin University, it has won unanimous praise.
For a long time, China has been a weak link in the development of textile chemical fiber testing instruments. Yang Dinghai, a senior engineer at Donghua University and a member of the Shanghai Invention Association, has been pursuing for decades and constantly innovating independently. He led the research team to develop nearly 20 innovative measuring instruments for textile and chemical fiber that have reached the advanced level at home and abroad, and achieved fruitful results. . Recently, he and the members of the research team have successfully developed several high-precision measuring instruments such as high-polymer thermal deformation performance measuring instrument, optical depolarizer, and automatic sound velocity orientation measuring instrument, which are not only for China. The textile industry provides the most advanced measuring instruments and excellent technical services, and has also contributed to the construction and development of textile disciplines in universities.
