Abstract: Disclosed herein is a printing process in which at least two inks are applied to a cloth according to an ink-jet system to conduct printing, which comprises at least three steps of: (a) applying the two inks to the cloth in such a manner that at least a part of the inks overlaps each other; (b) subjecting the cloth, to which the inks have been applied, to a heat treatment; and (c) washing the heat-treated cloth, wherein the cloth is a cloth comprising fibers dyeable with disperse dyes, and each of the inks comprises a specified coloring matter, a compound for dispersing the coloring matter and an aqueous liquid medium.

Abstract: Disclosed herein is an ink-jet printing cloth which is dyed with inks containing a reactive dye and is composed mainly of silk fibers, wherein the cloth contains an alkaline substance in an amount of 0.01 to 0.8% by weight based on the dry weight of the cloth.

Abstract: Disclosed herein is a printing medium comprising a cloth and having a Clark stiffness not lower than 10, but not higher than 400 at least at its ends.

Abstract: Disclosed herein is an ink-jet printing cloth composed of cellulose fibers, wherein the specific gravity of the cloth in an absolute dry condition is controlled within a range of from 1.45 to 1.49 by mercerization.

Abstract: An ink-jet printing process includes the steps of applying an ink to a cloth in accordance with an ink-jet system, subjecting the cloth to a reactively fixing treatment, and then washing the cloth thus treated to remove unreacted dye. The ink has a pH of from 4 to 9 and includes a reactive dye and an aqueous liquid medium and contains at least one of a dicarboxylic (or tricarboxylic) acid and an alkali metal salt thereof, and the cloth includes cellulose fibers and/or polyamide fibers.

Abstract: A cloth for textile printing, wherein any of the following substances is present on the surface of or in the interior of the cloth, (a) a tertiary amine compound having either a carboxyl group or a sulfonic group in its molecule, or a salt thereof, (b) a compound having a carboxyl group and an amide group, or a salt thereof, and (c) a compound having a sulfonic group and an amide group, or a salt thereof.

Abstract: A method of performing ink jet textile printing of a fiber product involves recording the border of a recorded image with a first ink containing an antibleeding agent, recording inside the border with a second coloring ink to complete the recorded image, and coloring the recorded image with heat. A printed textile article is made from fiber product substrate, and has an image formed thereon. The image has a border of a first ink containing an antibleeding agent, and an inner region located within the border is of a second coloring ink, the image having been colored by the application of heat.

Abstract: An ink-jet printing cloth is disclosed in which a selected type of polyethylene oxide is incorporated in specified amounts. The polyethylene oxide has a larger viscosity average molecular weight of from 100,000 to 3,000,000 and acts to pretreat a starting cloth material so as to be adequate for ink-jet printing. The ink-jet printing cloth,is highly capable of providing images of great color depth with sufficient brightness and sharpness but freedom from an objectionable bleeding. Also disclosed are a textile printing method using that printing cloth and a print resulting from this method.

Abstract: Disclosed herein is an ink-jet printing process comprising the three steps of (a) applying inks containing a disperse dye, a compound for dispersing the disperse dye and an aqueous medium to a cloth comprising fibers dyeable with disperse dyes according to an ink-jet system (b) subjecting the cloth, to which the inks have been applied, to a heat treatment and (c) cleaning the heat-treated cloth, wherein the inks comprise two or more inks which separately contain disperse dyes of the same hue and are different in dye concentration, and the thermal diffusivity of the disperse dye used in the ink having a low dye concentration is higher than that of the disperse dye used in the ink having a high dye concentration.

Abstract: An ink absorbent member is prepared for holding an ink stored in an ink storing section in an ink jet cartridge. The ink absorbent member contains not more then 0.20% by weight, on the basis of the member, of a fraction of soluble matters in a liquid containing an organic polar solvent incapable of reacting with the ink absorbent member such as monohydric alcohols or alkyl ethers of polyhydric alcohols.

Abstract: An ink jet printing method for effecting printing on a print medium such as a sheet of cloth by applying a jet of an ink to the print medium. The print medium is formed by preparing a sheet of cloth containing a cationic substance, preparing a backing sheet having a layer of an adhesive agent, and bonding the sheet of cloth to the adhesive surface of the backing sheet. After the jet of ink is applied to the print medium, the sheet of cloth is peeled off from the backing sheet and the freed sheet of cloth is rinsed with rinsing water containing a cation blocking agent, followed by drying.

Abstract: The present invention provides a textile printing method for forming a color mixture portion by partially overlapping at least three colors of inks including disperse dyes. In the printing method, the three color inks contain at least four disperse dyes in total.

Abstract: Disclosed herein is an ink-jet textile printing ink comprising a reactive dye and an aqueous liquid medium, wherein the ink contains at least one substance selected from the group consisting of dicarboxylic acids and alkali metal salts thereof.

Abstract: A textile-printing method imparts ink containing a cyan disperse dye and ink containing blue disperse dye on a cloth such that the cyan ink and the blue ink are at least partially overlapped, thereby forming a color mixture portion on the cloth, wherein a weight ratio of the cyan dye to the blue dye at the overlapped portion is specified in the range of from 10:1 to 100:1.
