Abstract
By following well-known methods, sulfonated arylamines dichlorotriazine based reactive dyes were synthesized, isolated and applied on knitted pure cotton fabric by exhaust process. Various parameters to define color and fastness properties were measured. Desire hue and properties can be obtained by changing the coupling reagent, sulfonated arylamine during the synthesis of sulfonated arylamines dichlorotriazine based reactive dyes. Orange, red and purple hue were obtained by using 1-naphthol-3-sulfonic acid, 6 amino, 1-naphthol-3-sulfonic acid, 7 amino and 1-naphthol-3,6-disulfonic acid, 8 amino respectively, while 1-naphthol-3,5-disulfonic acid, 8 amino and 1,5-disulfonic acid, 7 amino provided peach puff hue. The prepared dyes delivered a change in color equivalent to gray scale step 4/5 to 5 for wash fastness, gray scale step 3 to 4 for spotting with hydrochloric acid, gray scale step 3/4 to 5 for spotting with acetic acid, gray scale step 3 to 4/5 for steeping with sodium carbonate and gray scale step 1 to 3/4 for spotting,kith calcium hydroxide. Chromatographic, visible and infrared spectroscopic studies of synthesized dyes were also performed.
