The Process of Recycled PET filament Yarn

Currently, recycled PET filament yarns are mainly made with recycled waste plastic bottles. The production of these filament yarns requires a high level of cleanliness to avoid impurities in the spinning process, such impurities could affect the efficiency and the quality of filament yarns. For this reason, the journey from recycling waste plastic bottles to clean filament yarns is not an easy nor a short path to take.

Waste plastic bottles are recycled, washed, and sorted according to colors and levels of cleanliness. They are compressed into bales by machines. The bales are de-labeled, sorted, crushed, washed, removed of impurities, dehydrated, and processed into clean PET flakes, which are pelletized through the processing plant to become recycled PET chips, which will be sent to the filament yarns factory for high-temperature melt spinning, and finally, be used to make recycled PET filament yarns.
