The fibre grade pet bottle washing recycling line is a complete plastic recycling solution designed to process post-consumer and post-industrial pet bottles into clean,high-quality pet flakes suitable for polyester fiber production and other downstream applications.
Engineered for continuous industrial operation,the fibre grade pet bottle washing line combines bottle sorting,size reduction,washing,separation,drying,and flake cleaning in one integrated recycling line.It helps plastic processing plants convert waste pet bottles into a valuable secondary raw material while reducing landfill waste and dependence on virgin resin.

Typical Recycling Process
1. Bottle Bale Opening and Pre-Sorting
Compressed pet bottle bales are fed into the bale opener or bale breaker,where the material is loosened and evenly distributed.Manual or automatic sorting stations can be used to remove non-pet items,heavily contaminated bottles,pvc containers,metals,and other unwanted materials.
2. Label and Cap Separation
A label remover separates loose and attached labels from the bottles.Caps and rings,generally made from pp or hdpe,are separated during the washing and float-sink stages.Removing these materials improves the purity and consistency of the final pet flakes.
3. Bottle Crushing
The sorted pet bottles are processed through a heavy-duty wet or dry plastic crusher machine.The bottles are reduced into uniform flakes,improving the efficiency of subsequent washing and separation operations.Water-assisted crushing can help reduce dust and minimize heat generation.
4. Pre-Washing
A pre-washing unit removes loose dirt,sand,beverage residues,and surface contaminants before the material enters the main washing section.This step helps protect downstream equipment and improves overall washing performance.
5. Friction Washing
High-speed friction washers scrub the pet flakes against one another and against the internal screen surface.This process removes adhesives,organic residues,dirt,and other contaminants that remain after crushing.
6. Hot Washing
For fibre-grade applications requiring enhanced cleanliness,the fibre grade pet bottle recycling line can include a hot washing tank.Heated water combined with approved cleaning agents helps remove oil,grease,sugar residues,adhesives,and stubborn contamination from the pet flakes.
7. Sink-Float Separation
A sink-float separation tank uses differences in material density to separate pet from caps,rings,labels,and other plastics.Pet flakes typically sink,while pp and pe materials float,allowing them to be removed from the product stream.
8. Rinsing and Fine Separation
Multiple rinsing stages remove detergent residues and remaining contaminants.Additional separation equipment can be incorporated to improve the removal of pvc,metals,polyolefins,and other unwanted materials.
9. Dewatering and Drying
Centrifugal dewatering removes excess water from the washed pet flakes. A thermal or hot-air drying system then reduces residual moisture to a level suitable for storage,packaging,and further processing.
10. Final Flake Sorting and Packing
The dried pet flakes may pass through air classification,magnetic separation,metal detection,and optical sorting systems for final quality improvement.Finished flakes are then conveyed to storage silos,big-bag filling stations,or automatic packing equipment.
Output Material
The fibre grade pet bottle recycling machine produces washed and dried pet flakes with characteristics suitable for applications such as:
- Polyester staple fiber production
- Polyester filament yarn production
- Nonwoven fabric manufacturing
- Strapping production
- Pet sheet and thermoforming applications
- Engineering and compound plastic products
- Further pelletizing or solid-state processing
For fibre-grade production,the final flake quality depends on the quality of the incoming bottles,sorting accuracy,washing process,moisture control,pvc removal,color separation,and operating conditions.
Main Equipment Configuration
A typical 3-ton pet recycling system may include:
1. Bale opener or bale breaker
2. Conveyor and pre-sorting table
3. Metal detector or magnetic separator

Advantages for Plastic Processing Plants
High Production Efficiency
The 3-ton system is designed for large-scale,continuous pet bottle processing.Automated conveying and integrated washing equipment help reduce manual handling and improve plant productivity.
Improved Flake Purity
Multi-stage washing and density separation effectively remove dirt,labels,caps,adhesives,and other contaminants,helping produce a cleaner material for fibre manufacturing.
Reduced Operating Costs
Water recirculation,efficient motors,optimized heating,and automated controls help reduce energy,water,and labor consumption during operation.
Reliable Industrial Construction
The fibre grade pet bottle washing machine is manufactured for demanding recycling environments,with wear-resistant components and heavy-duty processing chambers designed for continuous use.
Flexible Plant Integration
The fibre grade pet recycling machine can be installed as a complete pet washing line or integrated with existing sorting,pelletizing,fiber spinning,or packaging equipment.
Environmentally Responsible Production
By recycling used pet bottles into reusable fibre-grade flakes,the fibre grade pet bottle cleaning system supports circular plastic production,reduces waste disposal,and lowers the need for virgin pet raw materials.
Control and Automation
The recycling line can be equipped with a centralized plc control system and touchscreen interface for managing:
- Conveyor speed
