A fibre grade pet bottle washing recycling line converts post-consumer PET bottles into high-purity flakes for polyester staple fiber (PSF) and textiles using advanced,automated washing technologies. Its key features include intensive hot washing for adhesive removal,high-speed friction cleaning,and optical sorting to remove impurities,ensuring efficient contaminant removal (often <100 ppm) and consistent,high-purity flakes.
These features details include as follow:
Intensive Hot Washing:
Superior Contaminant Removal:High-temperature washing with caustic soda effectively dissolves strong adhesive glue,oily residues,and label adhesives from PET flakes,which cold washing cannot remove.This is critical for producing clean fibers without clogging spinnerets.
High-Level Sterilization (Bacteria Elimination):The high-temperature process acts as a sanitation step,destroying bacteria and microorganisms,which ensures the hygienic safety of the recycled PET, particularly for sensitive applications.
Significantly Higher Product Purity:Hot washing improves the color,transparency,and purity of PET flakes by removing residual impurities.This leads to a higher-quality output that commands a higher market price.
Enables High-Value Applications (Food-Grade/Fiber-Grade):Intensive hot washing is a necessary step for achieving regulatory approval,such as EFSA or FDA No Objection Letters (NOL),enabling bottles to be recycled back into food-grade materials or high-grade textile fibers.
Improved Subsequent Processing:By removing stubborn residues,the subsequent extrusion and molding processes are less prone to failures,and the life of filtration components in the fiber production line is increased.
High-Speed Friction Cleaning
Intensive Contaminant Removal:The high-speed rotor acts as a final purification stage,utilizing high-intensity friction to strip away remaining labels,glue,and fine dirt.
Ideal for Fiber-Grade Quality:By ensuring extremely high cleanliness levels,this stage helps meet the strict requirements for polyester fiber manufacturing (low residues).
Reduced Downstream Contamination:Cleaner flakes reduce the risk of residues breaking down in the subsequent extrusion process,resulting in fewer breakages during fiber spinning.
High Throughput & Efficiency:The fibre grade pet cleaning system is designed for continuous operation at high speed,ensuring consistent material throughput.
Water & Energy Conservation:High-speed friction washers often utilize targeted spray rinsing and non-full-immersion designs, decreasing water and energy usage while maximizing scrubbing.
Extended Equipment Lifespan:Constructed from stainless steel and featuring robust engineering,this fibre grade pet bottle washing line is highly resistant to wear and corrosion in wet environments.
Optical Sorting to Remove Impurities:
Superior Material Purity:Advanced near-infrared (NIR) and color sorting technology accurately identifies and removes contaminants,including PVC,metals,and non-PET polymers.This ensures the high purity required for fiber grade and food-grade PET.
High-Throughput and Efficiency:Optical sorters significantly speed up processing compared to manual methods,capable of managing large volumes while maintaining consistent performance.
Reduced Labor and Operational Costs:Automation minimizes the need for manual sorting,leading to lower operating costs.
Enhanced Color and Type Separation:This fibre grade pet bottle recycling machine can precisely sort by color (e.g.,removing green or colored PET from clear streams) and specific polymer types, enhancing the value of the PET output.
Sustainable Material Processing:Optical sorting enhances the recycling process by enabling high-quality recycling and supporting a circular economy.
Increased Yield of Quality Material:By reducing contamination,manufacturers see a higher yield of premium,usable PET flakes for fiber,fabric,and textile production.
