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.
