The present disclosure discloses application of a deep eutectic solvent in textile dyeing, belonging to the technical field of ecological dyeing and finishing of textiles. A natural hydrophobic deep eutectic solvent system (HDES) is first used as a dyeing medium to perform reactive dyeing on cotton. Firstly, the prepared natural hydrophobic deep eutectic solvent is mixed with a small amount of dye aqueous solution at high speed to prepare dye liquor, and then cotton fabric soaked with alkali liquor is put into a dye bath for dyeing. The dyeing method doesn't require addition of inorganic salts and other dyeing auxiliaries, but uses a small amount of water and alkali agent to achieve the same dyeing effect as traditional water bath, and the dyeing medium is safe and environment-friendly. After dyeing, cyclic dyeing can be achieved by simply separating the dye bath, which truly realizes green dyeing of reactive dyes.
