Thermosetting ink printing why not block the network and wet and wet printing
This is the biggest question of traditional textile and apparel printing industry. When they saw the high-speed production of fully automatic garment printing machines (one in the fifth second), they were amazed; when they saw the thermosetting ink printing without cleaning the screen, they could continue printing the next day or even ten days and a month later. It is unbelievable. why? Because everyone thinks that printing coatings must contain adhesives, adhesives must be viscous (so they stick when they are not dry) and self-curing (of course they must be blocked).
Is thermoset ink (English: PLASISOL INK) a textile printing coating? of course! But it is a new kind of printing coating, that is printing coating without any adhesive. Therefore, the thermosetting ink does not have the stickiness and self-curing property of the adhesive, and thus has the conditions of never blocking the network and non-sticking the screen.
Having a non-stick screen version does not mean that it is absolutely non-stick, because the thermosetting ink is a paste. In order to achieve high-speed wet-to-wet printing, it is also necessary to master the process technology of thermosetting ink dot printing.
From this, we know that textile printing coatings have been divided into two categories: adhesives and non-adhesives. Thermosetting inks are non-adhesive textile printing coatings. Their exact name should be: hot-melt curing PVC textile printing coatings.
What pattern is suitable for thermosetting ink printing
Thermosetting inks can print any pattern, but the fine patterns and three-dimensional patterns of the printing power are unique advantages. This is also due to the nature of the thermosetting ink itself. Thermosetting inks have the characteristic of not blocking the web, making it very easy to print fine patterns, even if printed in dark-colored fabrics with 0.2-mm lines or dots with 60-line prints are not a problem. Compared with other textile printing coatings, thermosetting inks have the advantage that the solid content is 100%, so the printing thickness of thermosetting inks is the thickness after curing, as long as you can make a thick enough screen printing template. Edition prints solid graphics with the same thickness. While other textile printing coatings, whether aqueous or solvent-based, have a solid content of less than 60% or even about 5%. After the water or solvent is volatilized, the thickness of the cured graphic is only equivalent to the solid content.
What is the relationship between thermosetting ink printing and digital technology?
Thermosetting inks are mainly used for dot printing, especially spot color dot printing. Without digital computer technology, pattern separation and screening would be difficult. Therefore, it is precisely relying on the rapid development of digital computer technology network printing has been popular.
The CMYK four-color dot network has become a very convenient and simple thing. As long as people with basic computer skills can easily convert the computer's color image to CMYK mode, then set the number of screens, angles, dot shapes, print or photo film in the output settings (page setup). You can.
Spot color dot printing is the most advantageous technology for thermosetting inks. Spot color dot separation is a special technology developed by digital technology for thermosetting ink printing because it is not required for paper printing and textile sheet printing. Because the thermosetting ink has both hiding power and fine printing, it has the conditions for printing dot patterns on colored fabrics. Now, to solve the color separation software problem, this is the first in the T-shirt industry, the most developed in the United States to be solved, has launched the Fast Films and Spot Process two sets of spot color dot printing color separation software. If there is no spot color dot printing separation software, it will be complicated and troublesome to carry out spot color dot printing.
Thermosetting ink printing curing conditions
In the past, it has been stated that overheated inks do not contain any adhesive. Then, how does thermosetting inks combine with textile fabrics? It is by temperature!
The main component of thermosetting inks is chemically synthesized: PVC base + 100% solids
PLASTIFIER+ resin. It is a paste solid at room temperature and does not contain any volatile components. However, at a temperature of 130-160°C, the thermosetting ink begins to melt into a thick liquid, which penetrates down into the gap of the substrate (fabric fiber). At this time, after leaving the high temperature and returning to normal temperature, the thick liquid-like thermosetting ink will solidify into a solid (note that it has not been a paste-like solid in its original state). This solidified solid chemical composition is immersed on the surface of the substrate. It is firmly integrated into one, so that the purpose of printing is achieved.
Thus, the solid condition of the thermosetting ink is to control the temperature. The temperature determines the results of thermoset ink printing, such as fastness (bonding force), softness, and elasticity.
