Sublimation process
principle
The thermal sublimation process is a branch of the thermal transfer printing process, which belongs to a transfer printing process, mainly using disperse dyes. The printing principle is to print the pattern on the sublimation transfer paper with a special dye, and then transfer the pattern on the transfer paper to the fabric. Using the sublimation characteristics of disperse dyes at high temperature, the high temperature environment of about 200 ° C is used. Diffuses the dye into the fabric.
characteristic
1. Good color fastness and high durability. During the sublimation process, the dye directly infects the fabric and integrates with the garment. The printing life is equal to that of the garment, and the durability is good.
2. Dye sublimation technology can express the pattern more finely, with bright pattern layers, bright colors and a three-dimensional sense.
3. Green and environmentally friendly, no pollution, simple equipment, no need to wash, reduce sewage discharge.
The difference between heat transfer and heat transfer
Both the sublimation process and the heat transfer technology belong to the heat transfer technology, and both need to be transferred through the transfer paper in a high temperature environment. The difference is that the dye sublimation technology mainly uses disperse dyes, through the sublimation technology, the dyes penetrate into the fabric to color the garment. Heat transfer can use more materials, such as PU material and hot stamping paper, which can create various effects such as fluorescent glue Q hot stamping and hot stamping. The pattern is on the surface of the fabric and does not penetrate the inside.
