Sublimation transfer printing is a process technology that uses printing to print special printing dyes on heat transfer paper and then transfers the dyes to the fabric by heating/pressurizing. Specifically, it is based on For the sublimation characteristics of disperse dyes, select disperse dyes with a sublimation temperature range of 180~240℃ and mix them with the slurry to make color inks, according to different patterns/patterns requirements. Print the color ink on the heat transfer paper by printing. The transfer paper printed with patterns and patterns is in close contact with the fabric and processed on a transfer printing machine at 200~230°C for 10~30s. After diffusion, it enters the interior of the fabric to achieve the purpose of coloring. In the heating sublimation process, in order to make the dye directional diffusion, the dye-sublimation transfer ink on the bottom side of the dyed object is mainly imported from South Korea and Italy, which is expensive). The application field of the digital dye-sublimation transfer technology of printing technology is more Come more and more widely. To sum up, the sublimation transfer technology has the following 4 characteristics:
1. Good printing effect. The fabric printed by sublimation transfer technology has fine patterns, bright colors, rich and clear layers, high artistry, and a strong three-dimensional impression. It is difficult to achieve with other methods of printing. It can also print photography and painting style patterns.
2. The printed product feels soft and has a long service life. The biggest feature of dye-sublimation transfer is that the dye can diffuse into polyester or fiber, and the printed product feels very soft and comfortable, and there is basically no link layer. In addition, because the ink is already dried during the transfer process, the life of the image is as long as the life of the clothing itself, and there will be no wear and tear on the printed graphics and affect the appearance of the fabric.
3. The process is simple. The equipment investment is small, the flexibility is strong, and the rate of genuine products is high. Dye-sublimation transfer printing can print multiple color patterns at one time without the need for matching patterns and can print jobs in a short time according to the individual needs of customers.
4. Save resources and be environmentally friendly. Unlike traditional fabric printing, sublimation transfer printing does not require post-treatment processes such as steaming and washing, saving a lot of water resources, no sewage discharge, saving resources, and protecting the environment.
