Embodiment 1

[0012] A digital inkjet printing method, comprising the steps of: measuring the permeation rate of the fabric, measuring the surface tension of the dye, setting the piezoelectric pressure of the printing nozzle according to the permeation rate of the selected fabric and the surface tension value of the selected dye to Control the ink injection volume of the print head, 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 the 20 ink spot samples as the evaluation index of the degree of bleeding; the...

Embodiment 2

[0037]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 the bleeding rate of fabric, measuring the surface tension of a dye; setting piezoelectric pressure of a printing spray head to control the ink-jet amount of the printing spray head according to the bleeding rate of the selected fabric and the surface tension value of the selected dye; carrying out ink-jet printing; drying the ink after printing; and carrying out steaming, washing and drying; and in the step of setting the piezoelectric pressure of the printing spray head to control the ink-jet amount of the printing spray head according to the bleeding rate of the selected fabric and the surface tension value of the selected dye, the piezoelectric pressure of the printing spray head is determined after the bleeding rate of the dyes with different colors when mixed for dyeing, and the surface tension of the mixed dye on the corresponding fabric are measured respectively. Free from the thinking of the field, the bleeding phenomenon caused by diffusion of dye ink between the fabric and capillary tubes is well solved; the ink is saved; and the bleeding rate after the dyes with different colors are mixed is also considered.

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...
