VB-GREENSPIN-IPS Compact spinning machine for RECYCLED POLYESTER (rPET)
VB-GREENSPIN-IPS is a spinning system dedicated to rPET (bottle flake) where the rPET decontamination is perfor- med in solid state using a combination of infrared and vacuum.
- Process is ideal for treatment of the rPET in shape of flakes.
- Flakes are pneumatically loaded in the infrared unit, where they are efficiently heated using infrared, while the flakes are mixed with a special recirculation system
- Combination of temperature and vacuum allows the decontamination of the flakes from all volatiles without degradation of the product.
- Homogenization of the product is achieved by special recirculation system
- If required, the system with the adequate combination of temperature, vacuum and time, can increase the viscosity of the waste, compensating its viscosity loss.
- After the decontamination treatment, the granules/flakes are feeding a single screw extruder, where the polymer is melted and pushed into the mechanical continuous filtration. Once filtered the melt enters in the pelletizing unit, model to be selected according to the type of material.
- The polymer line is complete of mechanical continuous filtration in order to deliver to the spinning pump a clean melt for efficient spinning
- VB-MAST technology or traditional gravimetric system can be applied for dope dyed spinning.
