Problems solved by technology

Due to the lack of flexibility in the pattern change of this printing method, the transfer color is monotonous, and the roller needs to be re-engraved, which consumes a lot of time and resources, and the efficiency is low, the cost is high, and the garments produced are not fashionable.
With the progress of society and the wide application of digital printers, people began to use digital inkjet to make printing paper thermal transfer printing method, that is, entering the second stage, the advantage of digital inkjet printing thermal transfer printing is that the pattern change can be done through Computer printing is optional, and digital inkjet printers are used to print on thermal transfer paper to make decal paper, which has strong flexibility in pattern change; but it has the following disadvantages: (1) It needs to consume a lot of base paper made of wood pulp, which is wasteful. resources, which is not good for environmental protection; (2) The paper is easy to arch and deform after heating, which makes it easy to wrinkle during transfer, which affects the transfer effect; (3) When digital inkjet printers print patterns on thermal transfer printing paper, it is easy to scratch Nozzle, high production cost

[0023] A preparation method of digital inkjet printing thermal transfer printing film comprises the following steps:

[0024] 1. Mix carboxymethyl cellulose (CMC) and water at a mass ratio of 2:10. The water temperature is 70-90°C. Stir mechanically to form a viscous liquid, and let it cool down;

[0025] 2. Mix titanium dioxide and normal temperature water at a mass ratio of 4:10, mechanically grind for 15-25 minutes to make a liquid;

[0026] 3. Mix polyvinyl alcohol (BP-24) with water at a mass ratio of 3:10, soak for 2-3 hours at 100°C, stir mechanically and let it cool down;

[0027] 4. Grind the starch mechanically for 15-25 minutes, then add room temperature water to mix, the mass ratio of starch to water is 4:10, stir until evenly mixed;

[0028] 5. Mix the liquid made in steps 1-4 with the silicone defoamer, the mass percentage is: carboxymethyl cellulose solution: titanium dioxide solution: starch solution: polyvinyl alcohol solution: silicone defoamer = 70% : 7%: ...

Abstract

The invention relates to a digital ink-jet printing heat transfer printing membrane and a preparing method thereof, which have low-carbon and environmental-friendly effects and a good transfer printing effect, is low in production cost, and achieve the effects of no crinkling in transfer printing process and flexible transformation of patterns. The preparing method of the digital ink-jet printing heat transfer printing membrane comprises the following six steps: mixing carboxymethyl cellulose (CMC), titanium dioxide, polyvinyl alcohol (BP-24) and starch with water respectively in a certain ratio, stirring uniformly to prepare liquid, mixing the liquid with an organic silicon defoamer in a certain ratio, and filtering through a 200-mesh sieve to prepare coating glue; then uniformly coating the surface of a PET film with the coating glue through a coating machine; and drying and trimming to prepare the digital ink-jet printing heat transfer printing membrane.

Description

technical field [0001] The invention relates to a thermal transfer printing film for digital inkjet printing and a preparation method thereof, belonging to the technical field of textile printing and dyeing. Background technique [0002] The transfer printing process has gone through two stages: traditional gravure transfer printing and digital inkjet thermal transfer printing. In the first stage, people use traditional news base paper for transfer printing, use gravure printing machine, engrave patterns on the newsprint with ink through the roller, put the polyester fabric and transfer printing paper into the high-temperature roller at the same time, and the ink flowers Type transfer on fabric. Due to the lack of flexibility in the pattern change of this printing method, the transfer printing color is monotonous, and the cylinder needs to be re-engraved, which consumes a lot of time and resources, has low efficiency, high cost, and the garments produced are not fashionable...
