Polyester Staple Fiber Production Line


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%.

Introduction of PSF Production Line

Process flow of polyester spinning line from bottle flakes or chips

Polyester bottle flakes or chips – Heated and dried-hopper-Screw extruder –Melt filter – Spinning beam –Metering pump-Spinning packs –Quenching system-Spinning tunnel- Take-up machine – Capstan – Traverse machine (fiber cans)

Process Flow of Polyester After-treatment Line (Toyobo process route)

Creel – Prefeed Module (5 rollers + 1 immersion roller) – Immersion Bath – Immersion Roller – Draw Stand 1 ( 5 rollers + 1 immersion roller) – Draw Bath – Draw Stand 2 (5 rollers + 1 immersion roller) – Steam Heating Box – Draw Stand 3 (12 rollers) – Annealer (5 rollers) – Oiling Stacker – (Trio – Tension Roller) – Pre-crimper Heating Box – Crimper – Cooling Conveyor (or Tow Plaiter – Dryer) – Oil Sprayer – Tension Stand – Cutter – Baler

Process Flow of Polyester After-treatment Line (Fleissner process route)

Creel – Prefeed Module (7 rollers) – Immersion Bath – Draw Stand 1 ( 7 rollers ) – Draw Bath – Draw Stand 2 (7 rollers) – Steam Heating Box – Annealer (18 jacket rollers) – Cooling Sprayer – Draw Stand 3 (7 rollers) – Tow Stacker — Trio – Tension Roller – Pre-crimper Heating Box – Crimper — Tow Plaiter – Dryer – Tension Stand – Cutter – Baler
