Solvent-Based Separation for Blended Fabrics: Polyester-Cotton and Beyond
Recommendation: start a closed-loop pilot of solvent-based separation for polyester–cotton blends, prioritizing fabrics with ratios such as 65/35 and 50/50, employing a selective solvent system that dissolves polyester while leaving cotton as a recoverable solid; achieve at least 95% solvent recovery through multi-stage distillation and condensation; design with modularity to allow rapid scaling to other blended fabrics.
Process steps: sort incoming material into segments by blend ratio, pretreat to remove finishes, then apply a dissolution phase at 140–160°C under controlled agitation to separate the polyester-rich solution from the cotton-rich solid; recover cotton by precipitation and recycle polyester via re-precipitation, followed by washing and drying; test recovered fibers for tensile performance, color carryover, and binder residues, maintaining solvent purity above 99% to minimize contamination in the refeed stream.
Economics and environmental impact: energy intensity for pilot units ranges roughly 1.5–2.5 kWh per kilogram of fabric treated, depending on heat integration and solvent choices; solvent losses should be mitigated to below 5% of throughput through closed-loop recovery; landfill diversion increases as viscous scraps and finishing residues are redirected to solvent-based streams; worldwatch analyses indicate meaningful reductions in virgin polyester demand when closed-loop approaches scale, while iemi studies confirm stable product quality across multiple runs.
Supply chain and structure: a purchasing survey in janeiro highlights appetite among suppliers for modular separator skids and service packages; Retalhar’s guidelines emphasize safe handling, regulatory compliance, and routine solvents-management checks; implement a structure that assigns clear responsibilities for managing solvents, ordering inputs, and maintaining equipment; ensure quantities are aligned with batch sizes and forecasted demand for segmentation into multiple lines built to adapt to color and finish variations.
Quality, behavior, and limits: recovered polyester streams meet purity targets with minimal color carryover, enabling direct reprocessing into new fabrics; cotton fractions can be redirected toward regenerated cellulose or blended cotton fibers, depending on downstream value; some blends with specialized finishes or high-gloss coatings reduce separation selectivity and may require alternative solvent systems; cannot guarantee complete impurity removal in every feed; nevertheless, passes of independent testing confirm acceptable performance for numerous fabric segments and applications.
Implementation roadmap: initiate with 1–2 skid pilot in locations with favorable energy costs and regulatory support; set milestones for data collection on solvent recycling rates, fiber properties, and input quantities; expand to additional segments of fabrics as results stabilize; coordinate with purchasing cycles to align supplier qualifications and service contracts, leveraging built infrastructure to advance toward broader adoption and lower landfill dependency.
