There is provided a treatment agent for image recording including: a cationic polymer emulsion; and a water-soluble organic solvent including a glycol-based water-soluble organic solvent of which boiling point is not more than 200 C. The treatment agent satisfies the following condition (1): 20A60. In the condition (1), A: a content amount (% by mass) of the glycol-based water-soluble organic solvent, of which boiling point is not more than 200 C., in an entire amount of the treatment agent for image recording.

There is provided a set including: a water-based ink for ink-jet recording including a dye and water; and a treatment agent including a cationic polymer emulsion which includes a cationic polymer including a urethane structure. There is provided a recording method for recording on a recording medium which is fabric or recording paper by using the set.

A set includes: a water-based black pigment ink for ink-jet recording; a water-based yellow dye ink for ink-jet recording; a water-based magenta dye ink for ink-jet recording; a water-based cyan dye ink for ink-jet recording; and a treatment agent. The water-based black pigment ink for ink-jet recording includes a carbon black and water; the water-based yellow dye ink for ink-jet recording includes a yellow dye and water; the water-based magenta dye ink for ink-jet recording includes a magenta dye and water; the water-based cyan dye ink for ink-jet recording includes a cyan dye and water; and the treatment agent includes a cationic polymer emulsion.

There is provided a treatment agent applicable to a recording surface of a recording medium which is recording paper or fabric. The treatment agent contains: a non-cationic sizing agent; and at least one cationic substance which is selected from the group consisting of: a cationic polymer capable of forming a flexible film in a case that the cationic polymer is dried, a cationic surfactant, a polyvalent metal salt and a polyvalent metal ion.

A device for color-fixing processing on textiles includes a supercritical carbon dioxide fluid unit, a fixing liquid storage tank (2) and a fixing reactor (9). The fixing liquid storage tank (2) is below the fixing reactor (9) and sealed connected by a connecting device (6). The fixing liquid storage tank (2) has a cylindrical cavity in which a fluid distributor (4) is mounted. The fluid distributor (4) is composed of several interconnected pipes which bend down with the nozzles downward, and one of the pipes is used as circulated fluid inlet (1) connected with the supercritical carbon dioxide fluid unit, and the rest of the pipes are used as circulated fluid outlets.
