1- Polyester staple fiber production process flow
Pre-spinning Line:
Vacuum Drying Machine -> Storage Container -> Screw Extrusion Machine -> Sieve -> Spinning Apparatus (Metered Pump System, Spinning Pack, Spinneret) -> Cooling Unit -> Connecting Passage -> Withdrawal Wall -> Roller System -> Gear System for fiber movement
2- Post spinning Line:
2.1 Two-Dimensional Hollow Fiber Production Line:
Starting from the can creel, the inlet thread guide leads to the tow guide stand. Next, the fibers go through the dipping bath and then the first draw stand. They continue through the draw bath and the second draw stand. The fibers then reach the draw steam chest and move on to the third draw stand. After that, they pass through the tow stacker and enter the crimper steam box. The fibers are then processed by the crimper and conveyed by the tow conveyer. Next, they go through the relaxer and the tow tension stand before reaching the cutter. Finally, they are transported by the chain plate conveyor and pressed into bales by the baling press.
2.2 Three-Dimensional Hollow Fiber Production Line:
Similar to the two-dimensional line, the process starts with the can creel and the inlet thread guide. The fibers then pass through the tow guide stand and the dipping bath. Next, they go through the first draw stand and the draw bath, followed by the second draw stand. The fibers then reach the draw steam chest and move on to the third draw stand. Instead of a tow stacker, a tension control device is used in this line. The fibers then enter the crimper steam box and are processed by the crimper. After that, they are sprayed with silicon oil by the silicon oil sprayer. Next, the fibers go through the tow tension stand and are cut by the cutter. They then pass through the fiber spreader and the fiber leveler before reaching the relaxer. The fibers are then transported by the chain plate conveying system and pressed into bales by the baling press.
