Barvení bavlny reaktivními barvivy. / Reactive dyeing of the cotton.

The aim of this diploma thesis was to find out the change of the hue lightness saturation after the change of composition of dyeing liquor. The reactive dye Bezaktiv rot S-B was used for dyeing cotton. Dyeing was performed in the laboratory by exhaustion method with two concentrations of dye 0,5 and 2 %. The influence of the change of alkali and electrolyte concentration additions to dyeing bath liquor at different liquors dye ratio was studied. Sodium chloride and Glauber's salt as elektrolyte were used. The dyed samples were washed and then fixed by two types of fixative agents REWIN ACP and REWIN EL. After that the measurement of hue control and the evaluation of fastness to water and rubbing fastness were done. The results were displayed in L*a*b* space and CIE differences between chosen standards and samples were performed by Datacolor International DC 3890.
