Purui Polypropylene Fiber Regeneration Granulator

Product Overview

The Purui Polypropylene Fiber Regeneration Granulator is a specialized regeneration granulation machine designed for chemical fiber waste filaments and textile yarn scraps. It is a customized product with no fixed price, tailored according to the customer’s production capacity requirements. This equipment specifically addresses industry challenges such as tangled feed of fluffy fibers and bridging issues, efficiently enabling the resourceful reuse of textile waste filaments. It helps related enterprises reduce waste disposal costs while decreasing the need to purchase virgin chemical fiber raw materials, delivering both environmental benefits and economic value. The standard production capacity ranges from 200 to 1500 kg/h, compatible with various types of chemical fiber waste filaments and yarns, including polyester, polypropylene, nylon, as well as fibrous and yarny scraps of different lengths, meeting the recycling and processing needs of diverse textile waste forms.

Technical Principle

This equipment employs a combined process of a front-end chopping device, pre-compression feeding, and single-screw extrusion to complete the entire processing flow from textile waste to regenerated granules. First, long-fiber waste filaments are cut into short segments by the chopping unit, resolving the issue of long fibers easily tangling during feeding. Next, the pre-compression feeding structure compacts the fluffy short segments, preventing bridging during feeding 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 a segmented heating system to achieve thorough melting and plasticization, guaranteeing uniform fiber melting and complete plasticization. Subsequently, the vacuum degassing system activates to remove surface oils, moisture, and volatile substances, avoiding bubbling or broken strands during granulation. Finally, multi-stage filtration removes impurities from the raw material, followed by water-cooled pelletizing to produce finished granules with low impurity content and compliant moisture levels.

For textile waste recycling firms and chemical fiber regeneration businesses, it allows processing collected textile waste into high-value regenerated granules, opening new revenue streams.

Application Scenarios

The Purui Polypropylene Fiber Regeneration Granulator is primarily used in scenarios involving the recycling and granulation of various textile wastes, including polyester waste filaments, polypropylene yarns, nylon waste filaments, textile waste yarns, sewing thread scraps, chemical fiber filaments, and industrial fiber offcuts. It can be integrated within textile mills or chemical fiber plants to connect directly with production lines for immediate offcut recycling, or serve as core equipment in specialized waste recycling and regeneration enterprises, processing externally collected textile waste to produce high-quality regenerated chemical fiber granules supplied to downstream industries such as chemical fiber manufacturing and plastic product processing.

Solving Industry Pain Points

1. Addressing Feeding Challenges: To tackle the issues of fluffy, slender chemical fiber waste filaments easily tangling and bridging during feeding, the equipment features a front-end chopping device and pre-compression feeding mechanism, first cutting long fibers into short segments and then compacting them before feeding into the barrel, ensuring smooth and stable material delivery and preventing production interruptions caused by feeding problems.
2. Mitigating Finished Product Defects: To resolve concerns about oily residues, moisture, and bubbling or broken strands during granulation, the equipment’s vacuum degassing system effectively removes oils, moisture, and volatiles, complemented by thorough melting and plasticization along with multi-stage filtration, resulting in finished granules free of bubbles, with low impurity content and compliant moisture levels, thereby elevating granule quality.
3. Tackling Waste Disposal Challenges: To address the high cost of disposing of textile waste and its low resource utilization rate, this equipment transforms waste into reusable regenerated granules, achieving 100% resource recovery, significantly reducing waste disposal expenses while also cutting down on the purchase of virgin chemical fiber raw materials, creating dual economic value for enterprises.
