A3 sublimation paper is to use special heat transfer ink to print various patterns on a special kind of paper and then transfers the patterns to the product through temperature and pressure. This special paper in the thermal transfer process is called thermal transfer paper.
The advantages of the A3 sublimation paper can be divided into the following points:
1. 100% sustainable wood pulp, 100% renewable
2. Hybrid double-coating structure, support saturated printing 400% ink volume, no film cracks, no back penetration, good paper surface smoothness, high printing accuracy, clear layers, and wide color gamut
3. Inks with different surface tensions have good compatibility, high tolerance, and support industrial-grade unattended operation
4. High ink absorption capacity, fast-drying, reducing passive drying, effectively improving production efficiency, no re-pollution of decal movement, and reducing waste rate
5. High ink utilization efficiency and high transfer rate
How to use A3 sublimation paper:
1. Sublimation method
This is the most commonly used method. Utilizing the sublimation characteristics of disperse dyes, it is made of disperse dyes with a molecular weight of 250-400 and a particle size of 0.2-2 microns, water-soluble carriers (such as sodium alginate) or alcohol-soluble carriers (such as ethylcellulose), and oil-soluble resins. Ink is processed on a transfer printing machine at 200-230°C for 20-30 seconds to transfer the dispersed dye to synthetic fibers such as polyester and fix it.
2. Swimming method
The dye in the ink layer of the transfer paper is selected according to the nature of the fiber. Firstly, the fabric is filled with a mixture of color-fixing auxiliary and paste, then the dye is transferred from the transfer printing paper to the fabric, and the color is fixed by hot-press migration in the wet state, and finally, the wet treatment is carried out by steaming and washing. When the dye is transferred, a lot of pressure is required between the fabric and the transfer paper.
3. Melting method
The ink layer of transfer paper is based on dyes and waxes. Through melting and pressing, the ink layer is embedded in the fabric, so that part of the ink is transferred to the fiber, and then the corresponding post-treatment is carried out according to the nature of the dye. When using the melting method, greater pressure is required, and the dye transfer rate increases with the increase of pressure.
4. Ink layer peeling method
Using the ink that can produce strong adhesion to the fiber after being heated, the entire ink layer can be transferred from the transfer paper to the fabric under small pressure, and then the corresponding fixing treatment can be carried out according to the nature of the dye.
