The submicrometre particles extracted from polyester textiles during washing are more likely to be aggregates of PET oligomers, as supported by the pyrolysis–GC–MS chromatograms of a textile (Satin F) wash solution (sedimented fraction after centrifugation), methanol and ethanol extracts of a PET standard, a PET standard and method blank control.
