Reactive dyeing of the cotton.
Březinová, Lenka ; Prchal, Václav (referee) ; Fasurová, Naděžda (advisor)
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.

Building concept is based on many factors which determine such a small plot of land. The building symbolizes the tendency to intensify the development, but as the first of its kind must also adapt to a low area in which it is planted so far. To reduce the size of the contrast of adjacent materials are brand new roof slanted towards low buildings, creating a line that from the perspective of a street in perspective seemingly follows the curve formed ridges houses in the block. Localizing the edge industrial zones to buildings not only traced angular features, but also the chosen material, which is most surfaces aluminum and glass. High population how busy traveling and working in the expanded urban area, which becomes a new landmark building and gives overall charge.
