Final Spinning-Grade PET Pellets
1. Crystallization & Drying System
• Prevents PET hydrolysis and IV (intrinsic viscosity) degradation.
• Ensures moisture content ≤ 50-100 ppm before extrusion (critical for fiber-grade PET).
2. Single/Twin-Screw Extruder
• Provides high dispersion and homogenization of PET melt.
• Equipped with vacuum degassing to remove residual moisture and volatiles.
3. Melt Filtration System
• High-precision filtration removes fine impurities, gels, or black specks to ensure stable fiber spinning.
4. Strand Pelletizing System
• Melt strands are cooled in water and cut into uniform pellets.
• Produces smooth, cylindrical pellets ideal for fiber extrusion.
