Processing Equipment
High-performance polymer compounding requires continuous mechanical shearing and mixing to homogenize recycled resin blends. A co-rotating twin screw extruder provides the intense mechanical action needed to distribute additives and melt polymer flakes uniformly. This machine uses two intermeshing screws to convey and degas the polymer melt as it passes through the barrel.
Shear Control
Screw configuration can be customized with various kneading blocks and conveying elements to match the requirements of the resin. High shear zones melt the polymer quickly, while low shear zones prevent thermal degradation of sensitive recycled materials. This precise mechanical design allows the extruder to process polymer blends without causing excessive chain scission.
Degassing Performance
Venting zones along the barrel are equipped with vacuum ports to extract volatile contaminants and moisture. The action of the intermeshing screws continuously exposes fresh melt surfaces, accelerating the removal of unwanted gases. This efficient extraction is necessary to produce high-purity polymer suitable for fine denier textile filaments.
Textile Application
Recycled polyester processed through these machines shows high uniformity and stable intrinsic viscosity. This consistency is essential for spinning mills, where even small variations in polymer quality can lead to filament breakages during yarn production. By using optimized screw designs, manufacturers can produce high-quality yarns that meet the strict standards of the apparel industry.
The resulting yarn features a high tensile strength and uniform dyeability, making it ideal for high-end sportswear and technical fabrics. This reliability reduces machine downtime in garment factories.
