Solvent Residues from Dry Cleaning and Coating Processes
topic
Residual solvent analysis targets perchloroethylene and hydrocarbon dry cleaning solvent residues in cleaned garments using GC-FID or GC-MS headspace analysis, and quantifies DMF, toluene, and acetone coating process solvents in polyurethane-coated technical fabrics; static headspace and dynamic purge-and-trap sampling methods extract volatile residues without altering their distribution within the fabric matrix.
Role
Ensures dry cleaned garments and solvent-coated technical textiles do not present unacceptable inhalation exposure to residual halogenated and aromatic hydrocarbon solvents classified as toxic or carcinogenic, supporting occupational hygiene management in textile finishing and compliance with consumer product chemical safety standards.
