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.

The present specification relates to a method for manufacturing a polarizer, the method including: a step of dyeing at least one dye of iodine and dichroic dyes on a polyvinyl alcohol-based film; a first cross-linking step of cross-linking the polyvinyl alcohol-based film and the dye by using a first aqueous solution including a polyvalent carboxylic acid compound and a boron compound; a second cross-linking step of cross-linking the polyvinyl alcohol-based film and the dye by using a second aqueous solution including a polyvalent carboxylic acid compound and a boron compound; and a third cross-linking step of cross-linking the polyvinyl alcohol-based film and the dye by using a third aqueous solution including a polyvalent carboxylic acid compound, in which in the first cross-linking step and the second cross-linking step, stretching is performed along with cross-linking, and a polarizer manufactured by using the same.

An ink set contains: a pre-treatment fluid containing an organic acid and an amine compound; an aqueous pigment ink containing water; a pigment; and an organic solvent, and a post-treatment fluid containing a cationic resin particle.
