What is infiltration sublimation heat transfer? whats are the advantages of it?

Textile printing in the prior art mainly adopts infiltration sublimation heat transfer, which is to print patterns on thermal transfer paper, and then transfer them onto textile fabrics. It has the advantages of simple process, environmental protection, and bright colors after transfer. At the same time, it also has the defects of insufficient penetration, prone to whitening, turning over, and large color difference between front and back. For some high-end textiles, the penetration effect of the existing dye sublimation inkjet ink after transfer can not solve the common problems of whiteness, yarn turning, and large front and back color difference, and cannot meet customer requirements, so there is heat transfer penetration The emergence of the program.

Penetrating thermal transfer can solve three major pain points:

1. "Exposure"-the color is only printed on the surface of the textile fabric after thermal transfer. The swimsuit, shoe upper, home textile and other fabrics will be touched or pulled by hand to reveal the white background without color printed inside.

2. "Turnover"-because ordinary sublimation transfer ink is only printed on the surface of the fabric and does not penetrate the interior, white thread will be exposed at the needle and thread of the fabric after making clothes and scarves, which seriously affects the beauty of the clothes and product quality.

3. "Positive and Contrast"-because ordinary ink can only transfer one side in thermal transfer, the color cannot penetrate the reverse side, resulting in a large difference in color between the front and the back of some thick fabrics, especially for fabrics such as chiffon and silk scarves. Products with large positive and negative color differences are very uncoordinated and unsightly.

Advantages of infiltration heat transfer:

Compared with ordinary sublimation transfer printing, the ordinary sublimation pattern, the ink after transfer can only be printed on the top layer of the plush, and cannot penetrate to the bottom. You can see a clear white when you break it by hand. As for the pattern transferred by the plush penetration scheme, the ink not only transfers to the surface, but also penetrates into the bottom layer, and no whiteness is visible. Therefore, the advantages of permeable thermal transfer are the main solutions: whiteness, positive contrast and sand casting.

The infiltration thermal transfer scheme realizes the full fusion of ultra-fine nano-factors and dye molecules, and the ink can penetrate into the fabric fiber molecules during high temperature sublimation to achieve a strong penetration effect. It can solve the pain points of "exposing white, turning yarn, positive contrast" and other industries such as polyester chiffon, home textiles, shoe materials, and elastic cloth in the thermal transfer industry.
