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

[0011] A digital inkjet printing method, including the following steps: measurement of fabric bleeding rate, measurement of dye surface tension, and setting the piezoelectric pressure of the print nozzle according to the selected fabric bleeding rate and the selected dye surface tension value Control the amount of ink jetting of the print nozzle, inkjet printing, post-press drying, steaming, washing and drying. The specific measurement of the fabric penetration rate is as follows: draw the dots by computer, use several pieces of the same fabric sample with 20 dots each, each dot diameter is a standard value, and then print the pattern on the fabric by a digital printing machine; After drying at room temperature, they are processed separately. The area of ​​the ink dots in the spot sample can be obtained through image analysis software such as image-pro or CPAS, and the average area value of the 20 ink spots is used as the evaluation index of the degree of bleeding; = (Spot area...

Embodiment 2

[0036] The difference from Example 1 is that the fabric is pretreated before the measurement of the permeation rate of the fabric. 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 oxidant, 0.1% tartaric acid and 0.5% calcium carbonate powder; the paste A-9, SW-MN- The preparation steps of 08 are: Weigh the pastes A-9 and SW-MN-08, while keeping stirring, add the weighed pastes A-9 and SW-MN-08 to the soft water, and then Continue to stir until it is uniform; the preparation steps of the pretreatment liquid are: calculate the amount of urea required according to the amount of the treatment liquid, put it into warm water, then add glycerin, sodium sulfate and oxidant, stir until it is completely dissolved and the amount is gradually Add the required paste and keep stirring until the paste swells and there are no clumpy particles. During the process, the temperature of the pretr...

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 the world’s economic level, people’s demand for clothing and textiles is becoming more and more individualized and diversified. This has had a positive impact on the traditional textile industry, requiring that the manufacturing sector must also be transformed into Multi-variety and small batch production process. The emergence of digital printing technology exactly meets and adapts to this new market demand. Digital printing technology is a product of the integration of advanced technologies such as precision machinery, computer and photoelectric integration, and is a major breakthrough in traditional printing technology. Due to the large increase in customer demand for digital printing products of different fabric types, especially high-end fabrics, the demand for high-end cashmere fabrics i...
