PSF Production Line From CTMTC

Polyester Staple Fiber Production Line History

• The PSF machinery were manufactured in early 1970s.
• In middle 1990s, we began to research and develop 100t/d production line; and in 2002, this line was put into production.
• Developed the whole set of 120t/d production line in 2003.
• From 2005 to 2011, the 150t/d product line was put into batch production.
• In 2012, the 200t/d PSF product line ran successfully.
• Recent max. Capacity of one line: 225t/d.
• More than 200 lines have been running successfully all over the world, in which more than 100 are of large capacity.
• Till now, first-class fiber rate can reach over 98% and that of high-class fiber is over 95%.
