Problems solved by technology

This invention cannot suppress bleeding in printed images with gradation expression whose expressiveness is further enhanced
In addition, it is difficult to say that this method is oriented towards representing fine-line, detailed images
That is, it is necessary to accurately align the printing area of ​​the first ink and the printing image of the color ink, but since the fabric itself is easy to expand and contract, the alignment becomes very difficult
In addition, since the first ink itself bleeds onto the fabric, it is difficult to draw very fine lines in principle.
[0007] Based on the various methods described above, the inventors of the present invention conducted various researches on methods for suppressing bleeding by continuously supplying the functional liquid and the recording ink, and found the following problem: in order to stably impart the functional liquid, there is a limit As a result, the total amount of liquid applied to the fabric increases, resulting in worsening of the bleeding situation, or deterioration of printing quality such as a decrease in color density
However, in the case of thin fabrics, the anti-bleeding effect and the suppression of plain staining in the washing process are insufficient, and it is difficult to apply it under the condition of not limiting the type of fabric.

Embodiment 1

[0154] 〔Preparation of functional ink〕

[0155] The functional inks were prepared according to the formula shown in Table 1. Next, filtration was performed with a 3 μm membrane filter, and a degassing treatment was performed. In the degassing treatment, the prepared functional inks flow into the gas-permeable hollow fiber membranes, and the outer surface of the hollow fiber membranes is decompressed by a water flow aspirator, thereby removing the dissolved gas in the functional inks. In addition, after degassing, it is filled into a vacuum package to prevent the incorporation of air. The compounds used are shown below.

Embodiment 2

[0241] Change the functional ink F-1 of embodiment 1 and recording ink Y-1, M-1, the addition of the water-soluble polymer of the functional ink of embodiment 1 in the preparation of C-1 and recording ink Y, M, The addition amount of each resin binder in C is such that the total amount of the two nozzles from the first nozzle bracket is 18ml / m on the maximum concentration part of the monochrome 2 11ml / m of the functional ink from the nozzle on the second nozzle bracket 2 The amount of water-soluble macromolecules and resin binders given when the Y, M, and C recording inks are printed as a monochrome solid image of 10 cm × 10 cm is the amount shown in Table 7, and the same process as in Example 1 is carried out. evaluate. The results are shown in Table 7.

[0242] [Table 7]

[0244] As shown in Table 7, it can be seen that the total amount of the water-soluble polymer applied to the fabric by the functional ink and the amount of the resin binder applied to the fa...

Embodiment 3

[0246] In Example 1, the temperature of the heater H3 was controlled to change the surface temperature of the cloth portion to which the recording ink was applied, and the bleeding suppression effect was remarkable in the temperature range of 35°C to 70°C. Furthermore, the heating for drying makes the bleed-out suppressing effect more prominent than the case where the heater H2 is not used between the step of applying the functional ink and the step of applying the recording ink.

Abstract

Provided is an ink-jet textile printing / recording process, by which it is possible to form high-quality prints which do not suffer from bleeding, lowering in the density of developed color, contamination of non-printed white areas, or other faults. Thus, the ink-jet textile printing / recording process enables the expression of colorful designs. The ink-jet textile printing / recording process comprises applying a functional ink by an ink-jet system to at least portions of a textile where printed areas with the maximum density are to be formed, and then applying a recording ink to the resulting textile by an ink-jet system, wherein the functional ink contains both a water-soluble polymer and a water-soluble organic solvent, and the recording ink contains a disperse dye, a binder resin, and a water-soluble organic solvent.

Description

technical field [0001] The present invention relates to an inkjet printing and recording method. Specifically, it relates to an inkjet printing and recording method of supplying functional ink for improving printing quality and expressing colorful patterns before printing with recording ink. Background technique [0002] Inkjet printing technology is effectively utilized in various fields as an on-demand printing technology capable of directly printing on various base materials based on digital image data. In addition, in the field of inkjet printing and dyeing, many printing devices for printing on fabrics by the inkjet method have been put into practical use. However, when printing directly on fabric with an inkjet printing device, there are problems in that the bleeding of the ink cannot be sufficiently suppressed, or a sufficiently high image density cannot be obtained. [0003] In the past, in order to improve the final printing quality, in many cases, it was necessary...
