Abstract

DRIFT spectra were collected from dye mixtures extracted from small yarn samples taken from several areas of a worn test garment. Raw and pretreated data matrices were interpreted with the use of chemometrics (PCA, SIMCA, fuzzy clustering). This approach showed that spectra cluster and match according to their sampling area on the test textile. The DRIFT results provide detailed information that is not available from the application of the usual techniques (e.g., TLC) with such samples and therefore should be of use in forensics or similar work where comparisons of unknown, small dye mixtures are required.
