Waste Curtain Fabric Granulator

Product Overview

The waste curtain fabric granulator is a recycling granulation machine specially developed for PET waste fabrics and garment offcuts, enabling efficient resource recovery of textile waste. The equipment is compatible with pre-crushed PET fabric scraps and employs a dedicated high-shear single-screw extrusion process, which can achieve thorough melting and plasticization of flexible fiber waste. Paired with a multi-stage vacuum degassing system, it effectively removes dyes, additives, moisture, and odors. After multi-stage filtration, the material is extruded, water-cooled, and pelletized. It can also be connected to a decolorization pretreatment module to enhance the appearance of the recycled material. The equipment supports customization based on customer production requirements, with standard capacities ranging from 200 to 1500 kg/h, capable of continuous stable operation around the clock, helping to transform old clothes and waste fabrics from landfill or incineration into high-value resource utilization, significantly reducing enterprises’ solid waste disposal costs.

Technical Principle

The core technology of this granulator is based on a dedicated high-shear single-screw extrusion process, designed to handle pre-crushed PET fabric scraps for recycling. Once the fabric fragments enter the barrel, the high-shear screw structure rapidly breaks down the fibrous structure, while the segmented heating system ensures deep melting and plasticization, addressing the industry’s longstanding challenge of insufficient melting and poor plasticization of fabric fibers. Multiple vacuum vents installed along the barrel efficiently remove dyes, additives, moisture, and volatile odor-causing substances, preventing smoke and unpleasant smells during production. The molten material then passes through a multi-stage filter die to remove fiber impurities and thread remnants, ensuring the purity of the final pellets. Finally, the pellets are formed via an extrusion-water-cooling-pelletizing process; when paired with a decolorization pretreatment module, the appearance of the recycled material can be further improved, expanding its application scope.

Solutions to Industry Pain Points

1. Solving the problem of fabric fiber plasticization: Traditional granulators often struggle with insufficient melting and poor plasticization of flexible fabric fibers. This equipment adopts a combination of high-shear screws and segmented heating, thoroughly breaking down fibrous structures and achieving deep melting and plasticization, ensuring high-quality finished pellets.
2. Eliminating production smoke and odors: Dyes and additives contained in waste fabrics can produce pungent fumes during processing. The equipment’s multi-stage vacuum degassing system efficiently removes these volatile substances, significantly reducing production odors and improving workshop conditions.
3. Enhancing the added value of solid waste recycling: Previously, waste fabrics were mostly disposed of through landfill or incineration, causing environmental pollution without generating any economic benefits. This equipment transforms such waste into high-value recycled pellets, adding over 1,000 yuan per ton and creating new profit growth opportunities for enterprises.
4. Reducing solid waste disposal costs: As environmental regulations tighten, the cost of disposing of fabric waste continues to rise. By replacing traditional disposal methods with resource recycling, this equipment can substantially lower enterprises’ solid waste disposal expenses while alleviating pressure on environmental management.
