Polyester Fiber Recycling Pelletizer

Product Overview

The polyester fiber recycling pelletizer is a customized, dedicated pelletizing machine designed specifically for chemical fiber waste filaments and textile yarn scraps. It efficiently addresses industry challenges such as the tendency of fluffy fibers to entangle and bridge during feeding, enabling the resourceful reuse of textile waste. The equipment is compatible with various types of chemical fiber waste filaments and yarns, including polyester, polypropylene, nylon, as well as short and long filaments and yarns—covering multiple forms of textile waste. Its standard capacity ranges from 200 to 1500 kg/h, meeting diverse production needs of different customers. As a core product of the PURUI brand, this machine is manufactured in Nantong, built with mature technology and high-quality components. It boasts advantages such as thorough fiber melting, uniform plasticization, effective vacuum degassing to remove oils and moisture, bubble-free pellets, a compact structure, and convenient operation and maintenance. It can be directly integrated into textile mills’ edge‑cutting lines, providing a complete solution for processing textile waste.

Technical Principle

This equipment employs an integrated process of “front-end shredding unit + pre‑compression feeding + single‑screw extrusion,” tailored to handle the characteristics of fluffy, slender chemical fiber waste. First, long filament waste is cut into short segments by the shredding unit, resolving the issue of long fibers easily tangling during feeding. Next, a pre‑compression feeding mechanism compacts the fluffy short filaments, preventing bridging and ensuring stable feeding. Then, a high-shear screw structure breaks up fiber bundles, while segmented heating ensures thorough melting and plasticization, guaranteeing uniform melting of the fiber raw material. Equipped with a vacuum degassing system, it effectively removes surface oils, moisture, and volatiles, avoiding bubbling or breakage during pelletizing. Finally, multi‑stage filtration eliminates impurities, followed by water‑cooled pelletizing to produce high‑quality recycled pellets with impurity content ≤1% and moisture content ≤0.3%.
