Reutilization of PET waste to textile filament and fiber products

The VacuFil recycling process from BB Engineering GmbH, Remscheid/Germany, enables the manufacture of very homogeneous, viscosity stable rPET melt and ensures a precisely definable and reproducible raw material for downstream processes. Macro and microscopic melt homogeneity is achieved by means of homogenization drying, controlled plasticizing, gentle filtration and controlled vacuum degassing.
The company’s VarioFil R spinning systems have been used for converting PET re-granulates and PET flakes into POY/DTY for both textile and carpet applications. Spin dyed products made from PET recycled granulates are also being produced using VarioFil systems.
With their modular structure and a performance spectrum of between 300 kg/h and maximum 3,000 kg/h, VacuFil systems open up various possibilities for processing polyester waste bottle flakes, agglomerated spinning waste or a mixture of both can be processed into high quality PET granulate or fed directly into downstream processes. With an optional 3 DD mixer, producers can not only add additives to the melt, they can also easily change rPET ratios in the main melt from between 5% and 50% stream in order to comply with legal standards.
