Textile Mill Waste Yarn Recycling Pelletizer

Product Overview

The PURUI Textile Mill Waste Yarn Recycling Pelletizer is a specialized pelletizing machine designed for synthetic fiber waste yarn and textile thread scraps. Originating from NANTONG, 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 yarn. The equipment can be customized according to customer production requirements and is compatible with various types of synthetic fiber waste yarn and threads—including polyester, polypropylene, nylon—as well as diverse forms of textile waste like short and long filaments and yarns. It transforms all kinds of textile waste into usable recycled pellets, helping companies reduce waste disposal costs while decreasing their reliance on purchasing virgin synthetic fiber raw materials.

Technical Principle

This pelletizer employs a composite process featuring a front-end shredding unit, pre-compression feeding, and single-screw extrusion, ensuring efficient processing of textile waste throughout the entire operation. First, long-fiber waste yarn is cut into short segments by the shredding device, resolving the issue of long fibers easily tangling during feeding. Subsequently, a pre-compression feeding mechanism compacts the fluffy short segments, preventing bridging and ensuring stable material delivery into the barrel. Inside the barrel, a high-shear screw design effectively breaks up fiber bundles, working in conjunction with segmented heating to achieve thorough melting and plasticization, guaranteeing uniform plasticization. The equipment also includes a vacuum degassing system that efficiently removes oils, moisture, and volatile substances adhering to the fiber surface, thus avoiding bubbling or breakage during pelletizing. Finally, after multi-stage filtration to remove impurities, the material is extruded through either die-face pelletizing or strand-cutting methods, followed by water-cooling and pellet formation, yielding recycled pellets with low impurity content and compliant moisture levels.
