Chemical Fiber Filament Regeneration Granulator

Product Overview

The chemical fiber filament regeneration granulator is a customized granulation device specifically designed for chemical fiber waste filaments and textile yarn scraps. It has no fixed price and is tailor-made according to the customer’s production requirements. This equipment effectively addresses industry pain points such as loose fibers easily tangling and bridging during feeding, enabling efficient resource recovery of textile waste filaments. It is compatible with various types of chemical fiber waste filaments and yarns, including polyester, polypropylene, nylon, and other materials, as well as fiber and yarn scraps of different lengths. It serves as a core piece of equipment for textile mills, chemical fiber plants, and other enterprises engaged in waste recycling and reuse.

Technical Principle

This granulator employs a composite process combining a front-end short-cutting unit, pre-compression feeding, and single-screw extrusion to achieve a complete transformation from waste material into regenerated granules. First, long-fiber waste filaments are cut into short segments by the cutting device, resolving the issue of difficult feeding for long fibers. Then, a pre-compression feeding mechanism compacts the fluffy short fibers, preventing bridging and tangling during feeding and ensuring stable material delivery. Next, a high-shear screw structure breaks up fiber bundles, while segmented heating ensures thorough melting and plasticization of the fibers, guaranteeing uniformity of the material. A vacuum degassing system removes oils, moisture, and volatile substances adhering to the fiber surface, avoiding bubbles or broken strands in the finished granules. Finally, after multi-stage filtration to remove impurities, the material is extruded, water-cooled, and pelletized to produce standard-compliant regenerated granules.

Core Value of the Product

1. Efficient resource utilization: Achieves 100% resource recovery of textile waste, transforming previously difficult-to-dispose chemical fiber waste filaments and yarn scraps into reusable chemical fiber granules, turning waste into valuable resources.
2. Significant cost reduction and efficiency gains: With a maximum daily output of 36 tons of regenerated granules over 24 hours, it reduces annual purchases of virgin chemical fiber raw materials by more than 1,200 tons, while cutting waste disposal costs by 90%, substantially lowering both raw material and waste treatment expenses.
3. Solving industry challenges: Specifically addresses issues such as feeding tangling and bridging caused by loose, fine chemical fiber filaments, as well as bubbling and breakage in granulation due to oil and moisture on the fibers, thereby improving the stability and yield of granulation production.
4. Compliance with environmental regulations: By recycling and reusing waste materials, it reduces environmental pollution caused by chemical fiber waste, aligns with environmental policies, helps enterprises achieve green production, and enhances their eco-friendly image.

Target Customer Groups

The target customer base includes textile mills, chemical fiber plants, yarn processing facilities, textile waste recycling companies, and chemical fiber regeneration resource enterprises—businesses that generate large quantities of chemical fiber waste filaments and yarn scraps and require efficient equipment to recycle these wastes, reduce production costs, and meet environmental standards.

Application Scenarios

This granulator is primarily used for recycling and granulating polyester waste filaments, polypropylene yarns, nylon waste filaments, textile waste yarns, sewing thread scraps, chemical fiber long filaments, and industrial fiber edge trimmings. Whether it’s edge trimmings generated during textile production or various chemical fiber wastes collected by recycling companies, this equipment can transform them into high-quality regenerated chemical fiber granules, which can then be used to manufacture chemical fiber products, textile fabrics, and other items, achieving circular resource utilization.

Solving Industry Pain Points

1. Addressing feeding difficulties: For the challenge of loose, fine chemical fiber filaments easily tangling and bridging during feeding, the combination of a front-end short-cutting unit and pre-compression feeding mechanism cuts and compacts long fibers, ensuring smooth and stable feeding and preventing production interruptions.
2. Resolving granulation defects: To tackle issues like bubbling and breakage caused by oil and moisture on the fibers, a vacuum degassing system effectively removes oils, moisture, and volatiles, coupled with thorough melting and plasticization, ensuring finished granules are bubble-free and unbroken, thus improving product quality.
3. Reducing waste disposal costs: Traditional textile waste disposal is costly and has low resource recovery rates. This equipment achieves 100% resource recovery of waste while cutting waste disposal costs by 90%, reducing enterprises’ environmental investments and raw material expenditures.
4. Boosting production efficiency: Operating continuously for 24 hours, with a maximum daily output of 36 tons of regenerated granules, it significantly increases the efficiency of waste recycling, meeting the large-scale waste processing needs of enterprises.
