What is the difference between sublimation transfer printing and thermosetting printing?
Firstly, the concept of heat transfer printing is introduced: sublimation transfer printing and thermosetting transfer printing. Sublimation transfer printing is mainly used in chemical fiber fabrics and hard materials coated with thermal transfer coating. Thermosetting transfer printing is mainly used in cotton products. Although both of them print the pattern on transfer paper and fix it under high temperature and high pressure, there are essential differences. The printing ink used in digital printing and dyeing of chemical fiber fabric is sublimated disperse dye ink. The printing ink used in digital heat transfer of pure cotton fabric is divided into reactive dye ink and acid dye ink, and the sublimation paper is used in sublimation printing. Thermosetting transfer using thermoset transfer paper, can not be used instead of each other.
In fact, the best way to achieve pure cotton printing is digital direct-jet,digital direct-jet technology, the computer pattern directly on the cotton fabric, to achieve WYSIWYG printing effect. Simple operation, completely break through the traditional screen printing of color constraints, digital printing can achieve 16.7 million colors on the chromatographic printing, color is extremely rich, due to the absence of intermediate carriers, so the printing part is breathable, comfortable to wear, washing fastness level 4, repeatedly rubbing can not fade. Because water soluble consumables do not contain any harmful chemical components, they are environmentally friendly.
Sublimation heat transfer is the use of the sublimation characteristics of disperse dyes, that is, when the dyes printed on transfer paper reach the transfer temperature, the dyes begin to volatilize, and continue to penetrate into the fabric gap until the dyes on transfer paper are used up or tend to run out, the less residual dyes on transfer paper, indicating that the more transfer on the fabric, and also. The higher the saturation is, the richer and more vivid the pattern color is. This is also a core element of the quality of thermal sublimation
transfer paper. Because thermal sublimation is the process of diffusion of dyes to the fabric, thermal sublimation pattern transfer does not change the original texture of the material, the printing part is breathable, comfortable to wear, feel and feel good. Printing is another method: pure cotton or high cotton content fabric itself does not absorb color, if the use of heat sublimation printing pure cotton, very easy to wash away. In order not to wash it out, special thermosetting transfer paper is used. When making the mug, the surface of the mug has been coated with a color-absorbing coating, but the coating can not be applied to the clothes in advance, so it can only be applied to the transfer paper, so the printer is actually printing the pigment on the heat transfer paper with the naked eye. The quality of transfer paper is directly reflected in the thickness of the colloid layer, the worse the quality, the greater the thickness, if the area of the printing pattern is larger. At large, comfort and beauty as a measure of the utility function of individual clothing are no longer there.
We supplier many kinds sublimation material like sublimation paper, sublimation ink also the sublimation printer, any need, pls feel free to let me know, we will waiting for you!
