Disclosed are a method for dyeing and finishing a textile and a textile. The method includes steps of heating a bath liquid to a first temperature, and immersing a textile to be treated in the bath liquid for a first time; maintaining the bath liquid at the first temperature, adding a dye, a protective additive and a first part of a dyeing alkali agent sequentially thereto at a certain interval, and further immersing for a second time; heating the bath liquid to a second temperature at a first heating rate, then adding a second part of the dyeing alkali agent thereto, further immersing for a third time, and then taking out to obtain a dyed textile; washing and finishing the dyed textile to obtain a dyed and finished textile, wherein the dyeing alkali agent is sodium carbonate.

A dye additive suitable for use in improving the dyeing of aramid fibers includes non-water components dissolved in water. The non-water components include about 20-25% (w/w) sodium or potassium nitrate; about 20-25% (w/w) ketone solvent; about 30-40% (w/w) aromatic solvent; about 1-5% (w/w) of each of glycol ether, biodegradable solvent, acetic acid 56% strength or equivalent or equivalent amount of formic acid, brine salt, sodium or potassium hydroxide, and phenylenediamine, about 1-10% (w/w) of each of a strong acid, hydroxycarboxylic acid, and lanolin; wherein the water makes up about 50-70% of the weight of the dye additive and the non-water components make up about 30-50% of the dye additive. The dye additive may be added to a dye bath at a w/w percentage of about 0.25% to about 6%.

An ink jet textile printing penetrant includes a water-soluble organic solvent; a surfactant; and one type or two or more types selected from the group consisting of a chelating agent and an aromatic compound.

The present disclosure provides an ink fluid set containing an aqueous pre-treatment composition, a clear ink, and colored aqueous inkjet inks. This ink fluid set is particularly suitable for printing on polyester, cotton, and blends of cotton and synthetic textiles.

Disclosed is a process for printing on polyester fabric comprising (1) contacting polyester fabric with an aqueous solution comprising (A) 5% to 35% by weight of at least one multivalent cationic salt; (B) 0.1% to 5% by weight of a blocked polyisocyanate crosslinking agent, and (C) 3% to 40% by weight of a waterborne resin, all percentages based on the weight of the aqueous solution; (2) drying the polyester fabric to remove the water from the polyester fabric; and (3) digitally printing the pretreated and coated polyester fabric with a water-based textile ink.

An ink jet recording method performed on a fabric to which a hydrotropic agent is attached includes attaching an ink jet composition for textile printing including a metal complex salt dye, in which a hue angle h defined in CIELAB color space on printed textiles after printing is in a range of 260 or more and 310 or less, to the fabric using an ink jet method, in which there is a region in which a value of a ratio of a mass of the metal complex salt dye with respect to a total mass of dyes included in the ink jet composition for textile printing is 0.6 or more and 1.0 or less, and a value of a ratio of mass of the metal complex salt dye with respect to a mass of the hydrotropic agent in the fabric is 0.2 or more and 1.0 or less.

An image forming method includes: applying a pretreatment liquid, which is an aqueous solution, to a cloth material; heating the applied pretreatment liquid; and applying an ink onto the cloth material, after heating, to form an image on the cloth material by an ink jet method. After heating, the cloth material includes the pretreatment liquid and an amount of the pretreatment liquid per unit area of the cloth material is less than 30 mg/cm.sup.2. The ink includes a white ink containing titanium oxide particles having an average particle diameter of more than 10 nm and 200 nm or less.

Provided is a pretreatment agent for ink jet textile printing that can provide printed matters on fabric with high color-developing properties and less bleeding. The pretreatment agent includes at least water and (A) a multivalent metal ion and polymer fine particles, (B) a cationic polymer and polymer fine particles, or (C) cationic polymer fine particles.
