PET Nonwoven Fabric Regeneration Granulator

Product Overview

This is a specialized granulation machine designed specifically for recycling nonwoven fabric waste, equipped with a densifier-based pelletizing feed system that effectively addresses the industry’s challenges of bridging and slippage when feeding fluffy nonwoven fabrics. The equipment employs a low-temperature, precision temperature-controlled extrusion process, which maximizes the preservation of the core properties of nonwoven materials. It is compatible with various types of PP/PET nonwovens and meltblown fabric waste, capable of directly processing whole bundles of nonwoven fabric edge trimmings, eliminating the need for pre‑crushing steps and enabling efficient regeneration of waste materials, thereby helping enterprises reduce raw material costs and waste disposal expenses.

Technical Principle

The equipment integrates a densifier with a single-screw extrusion process, featuring a dedicated treatment workflow tailored to the characteristics of fluffy nonwoven waste: First, fluffy nonwoven waste is fed directly into the densifier chamber, where high-speed rotating and stationary blades shear and crush the material. During this rapid frictional heating process, the material self‑heats, contracts, and compacts into uniform pellets, increasing its bulk density by 3–4 times before being smoothly fed into the extrusion screw, thus fundamentally solving the issues of bridging and slippage during feeding. Subsequently, a low-temperature, precision temperature‑controlled extrusion process is employed, strictly regulating processing temperatures to prevent high‑temperature degradation of fibers. A vacuum degassing system removes oils and moisture from the material, followed by filtration to eliminate impurities, and finally water‑cooled pelletizing yields regenerated pellets with high performance retention.
