  Abstract

In this study, allergenic dispersed dyes Red1, Blue3, and Orange3 were dyeing at 0.05%, 0.1%, and 0.5% o.w.f. concentrations on polyester fabrics, and the dyeing fabrics were extracted with Pyridine and analyzed quantitatively using HPTLC(high performance thin layer chromatography). The developing solvent of the HPTLC stationary phase(plate) was mixed and development in a ratio of toluene: acetone (20:1 v/v), the concentration of the calibration curve of each allergenic dispersed dyes was 0.1 to 10 g/l, and the correlation coefficient (r2) was 0.999 or more. The quantitative limit was about 0.012 to 0.033 g/l and the detection limit was 0.039 to 0.105 g/l, and as a result of the precision test, the dispersion coefficient (C.V.) was less than 0.9%. In addition, through comparative analysis of HPTLC and HPLC, it was confirmed that the quality and quantity of each mixed dye allergenic dispersed dyes can be measured by HPTLC analysis.
