Sublimation dyeing technique
Mechanism & Process
Sublimation print is a kind of printing technique. The bond of fiber molecules is separated by heating the product to 180-190℃. A property of the polyester fiber (resin) is used to recombine with fiber molecules when heating stops. Applying pressure and heat sends vaporized ink molecules between the discrete polyester molecules. Then the sublimation ink is fixed and dyes the fiber molecules by the recombination after cooling. A design data generated on a PC is adjusted by inversion and original color profiling using a RIP server. The transfer paper printed by inkjet printer and target sublimation polyester cloth (resin) are superimposed. It is complete when the transfer paper is removed after having applied a heating crimp for approximately one minute.
The designs generated on PCs are accurately reproduced, because the the vaporized molecules of the ink used exclusively for sublimation dyes by penetration at the molecular level between molecules of the polyester fiber and retain its color and quality. Details of a photograph or a computer graphics do not ruin the texture of the cloth.
