Application of Different Inorganic Salts as Exhausting Agents for Dyeing of Cotton Knitted Fabric with Reactive Dye.
Aplenty of textile substrate especially cotton fabric dyed with reactive dyes because they produce a extensive gamut of bright colors with excellent colorfastness. As the reactive dye requires considerable quantities of salt and alkali for efficient application of colorants, this study is providing an assortment of knowledge about dyeing fabric with reactive dye and using some of the inorganic salts such as glauber salt, sodium chloride, zinc sulfate, aluminum sulfate, ammonium chloride and copper sulfate as an exhausting agent. Color strength measurements and colorfastness properties investigated here. In addition to, visage variation of dyed fabric also included in this study. In this experiment, 5 gm weights of samples dyed with 2% shade of a reactive dye at 60 0 c within 60 minutes where salts applied in three different concentrations like 50 gm/l, 20 gm/l and lastly 10 gm/l. It has observed that colorfastness of the reactive dyed sample with sodium chloride and zinc sulfate is slightly higher though the color strength of fabric dyed with glauber salt and sodium chloride are better than rest other salts.
