Analysis Of 32 Parallel Spinning FDY Key Technology And Device Industrialization

Less than p ago, Guo Dasheng, the Limited by Share Ltd's chairman of the Dalian synthetic fiber research and Design Institute, was the project leader. The project of "32 parallel spinning FDY key technologies and device industrialization", which was completed by the Dalian synthetic fiber research and Design Institute and Changshu Hengyi Chemical Fiber Co., Ltd., won the award of science and technology two in 2013. The project adopted the melt direct spinning, drafting, winding one step, parallel spinning technology route, increasing the output of single parts by increasing the number of single spindles, achieving large capacity and high efficiency. The technology is currently the most advanced FDY production facility of polyester FDY production technology and the largest number of spinning heads in the world.

< p > compared with the 24 head, the 32 parallel spinning equipment increased the output of single part by 30%, and the comprehensive energy consumption of the product decreased by 20%. It solved the problems caused by the increase of the number of single strand tow, such as the large area of equipment installation, the difficulty in lifting head, and the large difference of tow tension caused by winding angle.

The spinning equipment of 32 head < a href= "//www.sjfzxm.com/news/index_c.asp" > parallel spinning < /a > FDY mainly includes spinning components, wind storehouse, square cylinder shaped Yong Dao and Yong way exit. The spinning component is made up of four spray spinning components, the upper shell and the lower shell are surrounded by four independent sealing cavities, the four independent sealing cavities of the upper shell and the lower shell are arranged in parallel and arranged side by side, the inner side of the square body is equipped with a tow bundle, the inner surface of the tow bundle is near the surface of the tow, and the lower end of the square shaped channel is connected with the winding machine guide wire, and the tow enters the exit of the corridor. < p > it is understood that

According to Guo Dasheng, according to the introduction of "32 parallel spinning FDY key technology and device industrialization" project, the design concept of the single head 32 head FDY parallel spinning machine was put forward; the technology of polyester melt conveying and distribution, the new quadruple structure spinning component, the Yong channel bundle device and the synchronous speed control procedure of spinning metering pump and winding head were developed; the research on the integrated engineering of large capacity polyester FDY was carried out, and the production equipment and matching technology of single line annual output of 13000 tons and 32 parallel spinning of differential polyester FDY were developed. Special program control software and engineering configuration software were developed, and the automatic control level and control accuracy of the complete set of equipment were high. P

The single line production capacity reaches the international first-class scale, the comprehensive technology achieves the international advanced water skin, the comprehensive energy consumption achieves the international leading level.

< p > "a scientific research worker should share the concerns for the enterprise."

Guo Dasheng thinks so, and so does he.

After "P" > "a href=" //www.sjfzxm.com/news/index_c.asp "chemical fiber company" /a "1993, after the introduction of the complete set of production equipment, it once fell into a predicament of production shutdown. Later, although it was put into operation, the cost was very high.

To this end, the company was determined to make a thorough reform, after careful consideration, finally chose us.

In the past 1998~2002 years, they have worked with our company for three times, resulting in a qualitative change in the technology and production capacity of the company.

After three cooperation, the company's annual output reached 6500 tons, and its products increased by three grades, and achieved good economic benefits.

Guo Dasheng said.

The Dalian synthetic fiber research and Design Institute, while helping the chemical fiber enterprises to carry out technological pformation through low input, has also combined the improvement of technology level with strengthening management. A series of economic and technical measures have been adopted to carry out a series of economic and technical measures to carry out the "three aid" to the chemical fiber enterprises, that is, a group of enterprises to carry out technological pformation with low input and adjust the input output ratio, so that enterprises can gradually make profits from reducing losses; the two enterprises increase technological input, improve the technical content of products, make the production system rigid and flexible, and adapt to market changes; the three enterprises strengthen management work, promote overseas advanced working methods, continuously increase the added value of products, pform extensive operation into intensive operation, and gradually improve the overall efficiency, and they take the initiative to help enterprises solve problems and solve problems. < p

< /p >

< p > precisely because the Dalian synthetic fiber research and Design Institute serves wholeheartedly for the chemical fiber enterprises and has become a good partner with Changshu Hengyi Chemical Fiber Co., Ltd., the industrialization of "32 parallel spinning FDY key technologies and device industrialization" has begun.

< p > > Dalian a href= "//www.sjfzxm.com/news/index_c.asp" > synthetic fiber < /a > research and Design Institute is mainly engaged in chemical fiber and chemical fiber raw material technology research and development, equipment manufacturing, engineering design and engineering general contracting business, and is also the chief chemical fiber engineering company in China.

Although it is a turnkey project, the latest technology can quickly be industrialized, and it needs the support and cooperation of downstream enterprises to become an advanced productive force.

Our cooperation with Changshu Hengyi Chemical Fiber Co., Ltd. has really achieved 1+1>2.

Guo Dasheng said.

< p > aiming at "32 parallel spinning FDY key technology and device industrialization" project, the research and Design Institute of Dalian synthetic fiber research and Design Institute and Changshu Hengyi Chemical Fiber Co., Ltd. have been combined with many years' experience in designing chemical basis and function innovation, combined with many years of chemical fiber production experience of Dalian Hengyi Chemical Fiber Co., Ltd., to improve the efficiency of scientific research and shorten the industrialization time of scientific and technological achievements.

< /p >

< p > it is understood that the single line production capacity of the project is 13000 tons / year, and the product quality is uniform and stable. The products mainly include fine denier fiber, super fine denier fiber and a variety of modified fibers. The project has been successfully applied in the 70000 ton / year project of Hengyi Chemical Fiber Co., Ltd. and other enterprises in Changshu, and has achieved good economic and social benefits. It has a good exemplary role in promoting the upgrading of China's chemical fiber industry.
