    Abstract: Disclosed herein is an ink-jet printing process comprising at least the steps of: (a) successively applying, as ink droplets, at least two inks of different colors to a cloth to form a color-mixed portion; (b) subjecting the cloth to a heat treatment to fix dyes contained in the inks to the cloth; and (c) washing the cloth to remove unfixed dyes from the cloth, wherein the inks comprise water, an organic solvent and individual reactive dyes different from each other in reaction rate, and have a pH within a range of from 4 to 10, and the pH of the ink containing a slower-reacting dye is made higher.

    Abstract: Provided is an ink jet printing method for printing inks of at least two colors on a cloth by an ink jet system which comprises at least three steps of: (a) the step of printing, on the cloth, the inks of at least two colors of a black ink and an another ink of at least one color selected from the group consisting of yellow, orange, red, magenta, blue and cyan so that the inks may at least partially overlap, (b) the step of thermally treating the cloth printed with the inks, and (c) the step of washing the thermally treated cloth, said cloth comprising a polyamide fiber, said black ink containing, as a dyestuff, at least one selected from the group consisting of C. I. Acid Black 24, 26, 52, 52:1, 109, 155, 172 and 222, C. I. Direct Black 19, 62 and 113, and a dyestuff represented by the formula (1) wherein M is an alkaline metal, ammonium or an amine, or the formula (2) wherein X is a hydrogen atom, a lower alkyl group or a phenyl group which may be substituted by an SO3M group; m is O or 1; M is an alkaline metal, ammonium or an amine; each of A, B and C is a benzene ring or a naphthalene ring which may have a substituent, but B and C are not simultaneously the naphthalene rings.

    Abstract: A cloth suitable for ink-jet textile printing is mainly composed of cellulosic fibers having an average fiber length of 25 to 60mm, the cloth having a moisture percentage of 13.5 to 108.5%. The cloth may be mainly composed of cellulosic fibers having an average thickness of 0.6 to 2.2d and an average natural convolution of 70 to 150/cm, or mainly composed of regenerated cellulosic fibers. In an ink-jet textile-printing method, a textile printing ink is imparted to the cloth, and then a dyeing process is conducted, followed by a washing process.

    Abstract: Provided is an ink-jet textile printing process imparting an ink to a cloth by ink-jet method, which process comprises at least the following three steps of (a) imparting dots with a dot diameter of from r to 2r (r is nozzle pitch) to said cloth, by causing ink droplets to fly by means of a head having a plurality of nozzles capable of making a record at equal intervals in a density of from 3 nozzles/mm to 35 nozzles/mm; (b) diffusing the ink adhered to the cloth and simultaneously dyeing the cloth with the dye diffused in said cloth, by applying to said cloth having been subjected to the step (a) a heat treatment at 90 DEG C to 150 DEG C accompanied by steam; (c) washing away a dye having not been adsorbed or fixed; and said ink on said cloth in the step (b) being made to diffuse within the range of from 0.2r to 3r as a gain of dot diameter.
