Influence Of Different Alkali on Dyeing of Cotton with Homo-Bifunction Reactive Dyes

The study's goals are to ascertain how various alkalis affect cellulosic material and the dyeing process that result. In the presence of different fixing agents, the material was colored using homo-bifunctional reactive dye (high exhaust reactive dye). Sodium carbonate is one of the common alkalis; a comparison with potassium hydroxide and sodium silicate is being conducted. To optimize the dyeing parameters, the conventional recipe's alkali concentration was also adjusted and decreased. The color strength of the dyed cellulose samples was examined in order to ascertain how the various alkalis affected the dyeing procedure. Bright and deep hues are produced by bi-functional reactive dyes because they tend to be highly soluble and have good leveling capabilities. Effluent load and expense were decreased by lowering the alkali concentration, which also produced outstanding shades, equal leveling, and fastness attributes comparable to the conventional recipe.
