Fabrics of natural fibers such as wool, fabrics of semi-synthetic fibers such as cupra, rayon and diacetate, fabrics of synthetic fibers such as polyester, polyacrylic, polyamide and triacetate, and blends, blends and blends of these fibers. Cloths from mixed knitting, and textile products such as clothing, textiles, personal belongings, small articles such as marking tags, etc. made from these cloths are preferable, but not limited thereto.

The cloth to which the direct ink jet printing method according to the present invention is applied may be the above-mentioned cloth as it is, but preferably, the cloth is smoothed in advance by pressing or calcining. In order to obtain a clear image by accurately receiving the inkjet ink and these cloths, the cloth is previously impregnated with a thin layer such as a blur prevention layer, an ink receiving layer or a water repellent layer, coating, spraying, etc. Those subjected to so-called pretreatment, which is provided by using the above means, and those subjected to two or more kinds of the above means are more preferably used. The pretreated fabric of the present invention is pretreated with, for example, an aqueous dispersion or solvent dispersion (hereinafter referred to as “pretreatment agent”) containing a water-soluble resin and a softening agent, fine powder or the like. It is a thing.

The water-soluble resin usable in the present invention includes:
For example, oxidized starch, methyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose, tragacanth gum, guar gum, gum arabic, sodium alginate, polyacrylic acid soda, polyvinyl alcohol, polyvinylpyrrolidone, polyacrylamide, polyethylene oxide, polyarylamine hydrochloride, polydiaryl. Examples thereof include dimethylammonium chloride and casein. Among them, sodium alginate and carboxymethyl cellulose can be preferably used. Moreover, you may add a pH adjuster to the said pretreatment agent as needed. pH

Examples thereof include acetic acid, carbonic acid, citric acid, tartaric acid, maleic acid, phthalic acid, and their alkali metal salts, ammonium salts, triethylamine salts, triethanolamine salts, and caustic soda and triethanolamine.

The amount of the pretreatment agent used in the present invention applied to the cloth is 0.1 to 30% by weight, and the application method to the cloth is any of coating, impregnation and spraying. be able to. When the fabric is pretreated with the pretreatment agent, the image formed by the inkjet print (printing) is suppressed from blurring and the dye is deposited on the surface of the fabric, so that the dyeing rate of the dye is improved and the sufficient coloring density, Depth and sharpness can be obtained. Depending on the type of fabric,
It is desirable to change the pH of the pretreatment agent used in the present invention. For example, in the case of cotton, silk, hemp, and rayon, the pH is controlled alkaline, and in the case of nylon, the pH is controlled acidic. In the case of acetate and polyester, near neutral is preferable. Inkjet inks that can be used in the present invention include inks containing dyes such as reactive dyes, acid dyes, direct dyes, disperse dyes, and basic dyes. Use the ink of the optimum dye according to the type of cloth. You can Dyes, water, water-soluble organic solvents, pH adjusters, antifungal agents, surfactants, water-soluble resins and the like are appropriately used as constituent components of these inkjet inks.
Examples of the water-soluble organic solvent include glycols, glycol ethers, nitrogen-containing solvents and the like. As the surfactant, any of nonionic, anionic, cationic and amphoteric surfactants can be used, and they are selected according to the purpose. Printing with an inkjet ink, that is, image formation (printing or printing) is performed by scanning a printer recording head on a cloth or the like to apply ink. After this printing, a treatment such as a coloring process is performed, followed by washing and drying to obtain a desired finished dyed product (finished printed product).

The present invention provides a printing method by an ink jet system which realizes an image intended by a producer (manufacturer) or an orderer on a textile product. Generally, the image intended by the producer or the orderer, that is, the original image, when printing with an inkjet method, the image is first captured by a computer such as a scanner or created in the computer, and this image is displayed on the display, The image displayed on this display is finely adjusted as necessary to be the image (1) intended by the manufacturer or the orderer. This image (1) is printed (printed) on the cloth by an inkjet printer and is formed as the image (1) on the cloth, but the image (1) is retained as it is without any processing thereafter, and printing is completed. In most cases, the image (1) is post-processed by steaming, heat treatment, dye fixing, soaping, washing with water or warm water, and it is practically used for washing and wearing. In most cases, it is completed as a finished dyeing product that can withstand. The image (2) remaining on the finished dyed product after this post-treatment shows discoloration peculiar to each dye due to the post-treatment of the dye itself used, and the residual (dyeing) rate due to the post-treatment of the dye used. It varies depending on the individual dyes and falls off from the cloth in different proportions, resulting in a difference in hue and color density from the image (1), that is, a difference in chromaticity.

The inventors of the present invention conducted a preliminary test printing in the case where the discoloration due to the above-mentioned post-treatment and the discoloration of the respective dyes on the cloth at different ratios were carried out by the ink jet method on the cloth. After obtaining the image (1) with a predetermined amount of ink for printing, and the image (2) obtained by post-processing the image (1), the degree of "discoloration" and "dropping" is grasped, and in actual production By printing an actual image (3) with an ink amount (3) that is adjusted to a certain degree in a certain printing (printing), the image intended by the manufacturer or the orderer can be obtained on the finished dyed product by inkjet printing. The present invention has been made by grasping that it is a method. In the present invention, the chromaticity difference (ΔE) is measured in advance in many cases of combinations of types of fabrics, pretreatment prescriptions for fabrics, dye types used, post-treatment prescriptions after inkjet printing, and the like, It is also possible to make a database and apply it to a wide variety of inkjet printing methods. The above ink amount (3) may be an ink amount obtained by adjusting all the respective colors of the ink used, and at least CMYK.
It is also possible to use an ink amount in which one of the four colors (blue, red, yellow, black) is adjusted.

The ink jet (printing) method in the present invention is a conventionally known transfer ink jet printing method in which an image is once printed on a carrier such as transfer paper and then the image on the carrier such as transfer paper is transferred to a cloth. Is roughly classified into a direct inkjet printing method in which an image is directly printed and dyed on a cloth or the like, and the present invention is applied to printing in the direct inkjet printing method. The printing (printing or printing) by the inkjet method in the present invention is not limited to one of various inkjet methods such as a thermal inkjet method, a piezo inkjet method, a bipolar deflection method, a multi-deflection method, and the like. Among them, it is to print by the inkjet method that is appropriately selected and adopted, but it is the piezo inkjet method that the inkjet method of the present invention is optimally used, and the piezo inkjet printer is used. By printing a specific image, character or pattern on a textile product or cloth and fixing it by post-treatment, the most preferable dyed textile product can be obtained.

The method was to first capture the desired image with a scanner and process it with a computer. An image was obtained, and this image was printed on the pretreated fabric as a full-color image (1) with a predetermined ink amount (A) so as to obtain the full color image (1) on the fabric. 20 with steam
It was treated for a minute, then sufficiently washed with water and dried to obtain a printed material. By visually observing the image (2) and the image (1) on the printed material, it is apparent that the color density and the hue are It was different. This difference was measured using a photoelectric spectrophotometer to obtain the chromaticity difference (ΔE) of the difference between the image (2) and the image (1). A computer process is performed to correct this chromaticity difference (ΔE), and a full-color image (3) is obtained on the pretreated pretreated woven fabric by newly adjusting the ink amount (B) by adjusting the predetermined ink amount (A). I printed it. The image (3) on the obtained cloth is exposed to steam at 100 ° C. for 20 minutes.
After being treated for a minute, it was sufficiently washed with water and dried to obtain a printed material. The image (3 ′) obtained in this way was almost visually indistinguishable from the image (1) in terms of color density and hue.
