What is the purpose of salt in dyeing fabrics?
Applied while the dye is stillw et, large crystals of salt will absorb the dye, leaving behind a randomized pattern of light and dark color. It’s a technique often used to give texture to large areas of color in silk painting.

Salt is used as exhausting agent . During dyeing, the fabric will be immersed in water which will generate negative charges on the surface of fabric. This is called Zeta Potential. Anionic dyes are used often which will generate negative charges . Since the fabric also has negative charge it will repel . In order to fix the dye molecules to fabric surface it requires attraction .
Nacl is usually used as exhausting agent . When they are dissolved in water they form Na+ and cl- ions( common ion effect) . Na+ ions deposit on fabric and creates positive charge . So when dye is added the fabric will attract it .

Salt (usually common salt, NaCl or Glauber’s Salt Na2SO4) is used in dyeing of water-soluble dyes. The principle is simple - water is used as the medium (solvent) for dyeing and in the dye-bath water and sodium salt of dyestuff are added. The dyestuff gets ionized into Na+ cations and color bearing anions. When one immerse the substrate (i.e. fabric such as cotton), to have its coloration (dyeing), the anionic part of the dyestuff should migrate from solution onto the substrate. This process is called as EXHAUSTION of dyestuff for which the salt helps due to common ion effect (Na+).
