Legacy of Innovation and Authority in Spinning Technology
We began manufacturing synthetic fiber machinery and equipment in the 1960s. Shanghai Pacific was one of the officially authorized providers of spinning technology and machinery under the China Textile Industry system.
Over the decades, we have collaborated with global industry leaders such as DuPont, Zimmer, and Toray, providing tailor-made spinning machines through OEM partnerships.
Unique Technology That Others Imitate
Today, many spinning machines manufactured by other companies are derived from Shanghai Pacific's original technology. However, there are crucial differences in several core technical areas that set our systems apart, including:
-
Temperature evenness of the spinning beam
-
Polymer melt residence time and pressure control
-
Quench air flow speed, volume, and uniformity
-
Directional control of air flow
These critical aspects are optimized using our own proprietary technologies.
World-Leading R&D and Proprietary Quenching Systems
For decades, Shanghai Pacific has fused global innovations with local expertise. Our in-house R&D team has developed advanced spinning technologies by integrating the best of filament and fiber spinning processes.
We are proud to offer:
-
Spinning beam temperature control within ±1°C — a world-class achievement
-
Licensed radical quench systems
-
Semi-open circular quench systems
-
Fully closed circular quench systems
These technologies are developed and owned exclusively by Shanghai Pacific, ensuring superior performance and unmatched reliability.
Global Leader in PSF Production Line Supply
We have supplied some of the largest capacity polyester staple fiber (PSF) production lines in the world. Shanghai Pacific also holds the distinction of having the highest number of operational PSF lines globally, showcasing our dominance in this field.
​
One of our most prominent clients is Sinopec, the largest company in China and ranked No. 22 on the Fortune Global 500 list. As the biggest petrochemical complex in China, Sinopec also operates the largest polyester production capacity in the world — a testament to the trust placed in our technology and machinery.
