Abstract


In this paper, the influence of fluorescent bleaching agent or UVITEX BHT optical bleach, on the degree of whiteness of cotton fabric was examined. In the first phase of the test, the bleaching of cotton with the bleaching agent hydrogen peroxide was done, and in the second phase, the effect of fluorescent bleaching agents on the whiteness of cotton wool was tested, which was bleached in the first phase by chemical agents.The color strength (K/S) and CIE L*a*b* was examined under Coloreye - 300 spectrophotometer, too. The whiteness degree achieved with bleaching agent UVITEX BHT is almost twice larger than with chemical bleaching compounds, while the largest WI cotton fabrics whitened with hydrogen peroxide using the single-bone stress method was obtained for the concentration of the fluorescent UVITEX BHT bleach of 0.1%.

Keywords

CIE L*a*b* parameter, color strength, fluorescent bleaching agent
