Polyester Fiber | Since 2001, there were total 42sets 100tpd big capacity PSF lines built by Chinese companies, so among them, our group independently supplied 34 sets complete PSF lines, occupying 54% market, and seven PSF lines were built under the cooperation of us (for supplying spinning lines) and other makers (for supplying draw lines), which occupying 16.67% market. By far, we supplied the biggest capacity PSF lines in the world, and it also owns the most PSF running lines in the world. And the typical customer Sinopec is the biggest company in China (listed at No.22 of Fortune Top Worldwide 500), and Sinopec is also the biggest Petrochemical Complex in China and owns the biggest polyester capacity in the world.
Our group started synthetic fiber machinery & equipment fabrication since 1960’, it used to be the authorized spinning technology and machinery licensor and producer by China Textile Industry during the planning economy 25 years ago. It was the first Chinese company that developed 4000tpa, 7500tpa, 15000tpa PSF line technology since 1970’ and 1980’, and it built about 40 lines in the above capacity. It is market occupying rate in 1990 was 100% in China.
Our group ever cooperated with Barmag in 1980’ & 1990’ in developing SW4 series POY spinning & winder technology, and it founded the joint venture with Barmag in the middle of 1990’ of producing SW6 & CW, SP40, SP50 series high-speed spinning machines, and exported to Australia, Indonesia, and India. Our group has also worked with Dupont, Zimmer, Toray for their tailor-making machine fabrication in the OEM working style. Currently all other spinning machines produced by other companies are copied from our group technology, hence there definitely exists difference in critical technical items, especially in temperature evenness of spinning beam, polymer melt residence time/pressure control, quench airspeed, amount, pressure, flow direction uniformity control, etc., we have our own specific technology.
For long period, our group has been combining worldwide advanced technology in R&D, developing its own licensed & advanced spinning technology through combining filament & fiber spinning process advantages, the evenness of spinning beam can be controlled within ±1’C it is really the leading technology in the world. we also independently developed the own licensed technology of radical quench, semi-open circular quench, full close circular quench, etc. This technology can form a series of spinnerets atФ238、Ф328、Ф405. And recently, our group has successfully developed bi-component PSF lines, bi-component spun-bond lines, etc.
