With the deepening of the public's environmental awareness, keywords such as green, environmental protection, and low pollution have gradually become the core of manufacturing development. The printing, dyeing and printing industry, one of the polluters, has received special attention. Driven by environmental protection, sublimation digital printing has gradually entered people's vision.
The sublimation transfer technology is also called gas-phase transfer. Different from the film transfer technology, the sublimation transfer technology is to print the picture in the form of mirror surface on the transfer paper with special coating treatment with the sublimation ink, and form a dry pattern on the paper surface after drying. Under high temperature conditions, the ink sublimates, so that the pattern is transferred to the target substrate. After transfer, no other substances remain on the surface of the substrate, which does not affect the feel of the substrate.
The dye sublimation transfer technology is simple in process, and there is no dye wastewater discharge in the production process. It can pull the "pollution" image of the traditional printing and dyeing process. At the same time, it has the advantages of bright colors and distinct layers. It can truly achieve the photo quality printing effect and is widely used in various Chemical fiber fabrics and specially treated metal, ceramic, glass and other material surfaces.
The relevant consumables (sublimation ink, sublimation transfer paper, etc.) in the early days of sublimation transfer rely on foreign imports. Due to cost constraints, they are mainly used in personalized customization and other small production lines.
At present, sublimation transfer technology is widely used in the following markets:
1. Clothing fabrics, home textiles, umbrella fabrics, carpet fabrics, advertising fabrics and other fabric printing.
2. Metal surface decoration such as metal decorative plate, anti-theft door, handicraft after special treatment.
3. Specially decorated glass, ceramic surface decoration and high temperature resistant plastic material surface decoration.
4. Surface decoration of leather.
