Problems solved by technology

Therefore, at present, the industry generally adopts the method of fabric pretreatment to prevent the ink on the subsequent printing from seepage, such as adding an anti-seepage agent to the pretreatment liquid, but the effect of anti-seepage is general, because the seepage cannot be prevented. There must be capillaries between fabric fibers, and it is impossible to prevent the occurrence of capillary phenomena. If you can jump out of this thinking pattern and make full use of infiltration, it may have unexpected effects

Embodiment 1

[0010] The digital inkjet printing method comprises the steps of: measuring the permeability rate of the fabric, measuring the surface tension of the dye, and setting the piezoelectric pressure of the printing nozzle according to the permeability rate of the selected fabric and the surface tension value of the selected dye to control the printing. Ink injection volume of the nozzle, inkjet printing, post-press drying, steaming, washing, drying. The determination of the fabric permeability is as follows: draw a sample by computer, use several pieces of the same fabric sample with 20 dots each, and the diameter of each dot is a standard value, and then print the pattern on the fabric by a digital printing machine; After drying at room temperature, treat them separately, and use image analysis software such as image-pro or CPAS to obtain the area of ​​the ink dots in the spot sample, and use the average area value of 20 ink spot samples as the evaluation index of the degree of ble...

Embodiment 2

[0013] The difference from Example 1 is that the fabric is pretreated before the measurement of the permeability of the fabric, wherein the weight fraction of each component of the pretreatment liquid is: 2% paste A-9, 2% SW-MN -08, 3.5% glycerin, 4.5% urea, 10% sodium sulfate, 0.4% weak oxidizing agent, 0.1% tartaric acid and 0.5% calcium carbonate powder; the paste A-9, SW-MN- The preparation steps of 08 are: weigh the paste A-9 and SW-MN-08, and add the weighed paste A-9 and SW-MN-08 into soft water while stirring, and then Continue to stir until uniform; the preparation steps of the pretreatment liquid are: calculate the amount of urea required according to the amount of the treatment liquid and put it into warm water, then add glycerin, sodium sulfate and oxidant, stir until completely dissolved and then gradually Add the required paste, and keep stirring until the paste swells and there are no lumps. During the process, the temperature of the pretreatment liquid does not...

Abstract

The invention discloses a digital ink-jet printing method. The digital ink-jet printing method comprises the following steps: measuring a fabric seeping rate; measuring dye surface tension; setting piezoelectric pressure of a printing spray head according to the seeping rate of the selected fabric and the surface tension value of the selected dye to control ink jetting amount of the printing spray head; carrying out ink-jet spraying; drying after printing; steaming; washing; and drying. According to the digital ink-jet printing method disclosed by the invention, the thinking set of the field is jumped out, and the way to prevent seeping is changed into creation of guiding, utilizing seeping and reversely thinking, so that the seeping phenomenon caused by diffusion, in capillary tubes of fabric, of the dye ink is solved very well, and the dosage of the ink is saved.

Description

technical field [0001] The invention relates to the field of jet printing, in particular to a digital ink jet printing method. Background technique [0002] With the overall improvement of today's world economic level, people's demand for clothing, textiles, etc. is becoming more and more individualized and diversified, which has brought a certain positive impact on the traditional textile industry, requiring that the manufacturing field must also be transformed into Multi-variety and small batch production process. The emergence of digital printing technology just meets and adapts to this new market demand. Digital printing technology is the product of the integration of advanced technologies such as precision machinery, computer and optoelectronic integration, and is a major breakthrough in traditional printing technology. As customers' demand for digital printing products of different fabric types, especially digital printing products of high-grade fabrics, is increasing...
