This AATCC test method provides a comprehensive set of guidelines for the qualitative identification of various chemical finish components on textile fibers, yarns, or fabrics. It is not a rigid procedure but a flexible framework allowing analysts to select appropriate techniques. The primary approaches include sequential solvent extractions to isolate finishes, followed by analysis of the extracts using advanced instrumental methods like Infrared Spectroscopy (IR), Gas Chromatography (GC), and High-Performance Liquid Chromatography (HPLC). The method also covers direct analysis on the fabric using techniques such as X-ray fluorescence and reflectance spectroscopy, as well as simpler chemical spot tests for specific components. The document emphasizes laboratory safety, proper sample preparation, and the importance of considering potential interference from residual processing chemicals like dyes, sizes, and surfactants. It serves as a crucial resource for laboratories performing quality control, failure analysis, or competitive product evaluation in the textile industry.
