Problems solved by technology

But on other materials, such as plastic materials, the process maturity is still not enough
[0004] Due to its transparency, the transparent plastic cushion has a smoother microscopic surface, which leads to the inability to guarantee the stability of digital inkjet printing and dyeing patterns, which has become a technical bottleneck for the application of digital inkjet technology on transparent plastic materials.

Embodiment 1

[0033] Embodiment 1, material preparation standby.

[0034] Cut the raw materials of transparent plastic cushions according to the process indicators and prepare the materials. After the computer is turned on, it calls the predetermined pattern and checks the connection between the computer and the digital inkjet machine. After reaching the standard, adjust the printing port of the digital inkjet machine in place according to the process indicators, and start the machine to preheat at the same time.

[0035] The preheating time and the pretreatment of printing materials are often basically matched, just to achieve the sequential continuity of the printing process.

Embodiment 2

[0036] Embodiment 2, printing material pretreatment.

[0037] (1) Rapid acid etching at low temperature, soak the cut transparent plastic cushion in an acidic solution with a liquid temperature of 0-2°C, take it out after soaking for 5-6s, and place it on a stainless steel mesh screen for 20s;

[0038] (2) Normal temperature solvent cleaning: The transparent plastic cushion after the previous step is immediately transferred to the first cleaning pool containing inorganic-organic two-way solvent, the liquid temperature is normal temperature, shaking / vibration cleaning for 10 seconds, and placed on the stainless steel mesh screen for 20 seconds;

[0039] (3) Cleaning with high-temperature water: The transparent plastic cushion after the treatment in the previous step is immediately transferred to the second cleaning pool containing clean water, the liquid temperature is 65°C, and the shaking / vibration cleaning is performed for 10 seconds;

[0040] ⑷Rinse with high-temperature wa...

Embodiment 3

[0042] Embodiment 3, inkjet printing.

[0043] Send the processed transparent plastic cushion into the preheated digital inkjet machine, start the inkjet printing process through the computer, and complete the stable inkjet printing of any specified pattern.

Abstract

The invention discloses a stable inkjet printing improvement method for transparent plastic cushions. The raw materials of transparent plastic cushions are cut according to the process indicators and then prepared, and then undergo rapid low-temperature acid etching, normal-temperature solvent cleaning, high-temperature water cleaning, and high-temperature cleaning. After rinsing with clean water and drying with high-temperature airflow, inkjet printing is carried out. On the premise that the transparency of the plastic cushion is almost not lost, the stable inkjet printing of the transparent plastic cushion is realized, which is outstanding in practicability and progress.

Description

technical field [0001] The invention relates to a printing and dyeing method, in particular to an inkjet printing and dyeing method for transparent plastic cushions. Background technique [0002] Digital inkjet printing technology has unique advantages in the printing and dyeing industry because it can realize the printing and dyeing of any pattern and achieve the printing effect of "what you see is what you get". [0003] At present, the printing and dyeing technology of digital inkjet for specific textile materials such as paper and silk has been very mature, and it meets the process and use requirements in terms of pattern brightness and printing stability. But on other materials, such as plastic materials, the process maturity is still not enough. [0004] Due to its transparency, the microscopic surface of the transparent plastic cushion is smoother, which leads to the inability to guarantee the stability of the pattern of digital inkjet printing and dyeing, which has ...
