Mechanical Recycling
Mechanical recycling involves the physical reprocessing of polyester waste without breaking down the polymer chains. In this method, PET is collected, cleaned, and mechanically shredded into small flakes, which are then melted and extruded into fibers.
Process Overview
- Collection and Sorting:
The first step in mechanical recycling is collecting PET waste, such as plastic bottles or textile offcuts, and sorting them to ensure consistent quality. - Cleaning:
The sorted PET is thoroughly cleaned to remove contaminants such as labels, adhesives, and residues. Effective cleaning is critical for producing high-quality recycled fibers. - Shredding:
The clean PET is shredded into flakes or chips. The size of the flakes can affect the melting behavior and fiber properties in later stages. - Extrusion:
The shredded material is melted and extruded through spinnerets to form fibers. The process typically involves a single melting cycle, which is less energy-intensive compared to chemical recycling. - Spinning:
The extruded fibers are spun into yarn using standard techniques, resulting in recycled polyester yarn.
Mechanical recycling is generally more cost-effective and energy-efficient than chemical recycling. However, the process can degrade the polymer chains, leading to a reduction in fiber quality. This degradation manifests as lower tensile strength, color inconsistencies, and reduced durability in the final product.
