Study Of the Hydrolysis of Reactive Dyes

Popis výsledku v původním jazyce

Reactive dyes are called according the ability to create covalent bond between dyestuff and fibre polymer. The dye can react with hydroxyl groups of the cellulose in dyebath during cellulose dyeing. The description of behaviour of hydrolysed reactive dyeis the main aim of this contribution. Firstly, the ratio between active and hydrolysed dye was determined by the help of liquid chromatography. The presence of hydrolysed dye is evident after 15 minutes from the beginning of dyeing process, at the end of dyeing process is bath composed from hydrolysed dye mainly. Second part is detection of substantivity of hydrolysed dye. Material was dyed in bath contains hydrolysed dye and its uptake was determined by spectrophotometric measuring. Results were compared with of substantive sorption of active dye and the substantivity of hydrolysed dye is similar.
