Abstract
The purpose of this paper was to present the role and function of salt in dyeing of cellulosic fabrics. In aqueous medium, cellulosic fabric such as cotton, viscose or linen acquires negative charge and thus repels negative charged dye anion during dyeing. Such repulsion in the dye bath between fibre and dye is offset by salt. Salts play the role of glue holding the dye molecules in the cloth, and a certain percentage of dyestuff fixed with textiles is added to the alkali. Because of this, salt is used as an exhausting agent in the textile dyeing process with various colorants (direct dye, reactive dye). As an exhausting agent, inorganic salts such as glauber salt, sodium chloride, zinc sulphate, aluminum sulfate, ammonium chloride and copper sulfate. The dyeing efficiency of the various types of salt is determined by the percentage exhaustion, color intensity and color fastness.
