1, The dyeing property of disperse dyes: can sublimation dye temperature at 180 degrees Celsius, temperature, color changes, and edge of seepage.
2, Good dispersion dyes: temperature within the 180~210℃ sublimation dye dyeing curve is flat. Dyeing temperature has little effect, it is more appropriate to transfer printing with disperse dyes.
3, The dyeing property of disperse dyes: 180~210℃ case can't be very good sublimation, dye stain. Increase the temperature, you can get a good stain. This kind of dye, highly dependent on temperature.
According to the above situation, suitable for printing dyes should have the following conditions:
(1) The printing dye must be more than 210℃ to complete sublimation ink fixation on the fiber, washing fastness and ironing fastness
(2) The dye can be fully heated and transformed into a large dye molecule, which is condensed on the surface of the fabric
(3) The dye attached to the transfer paper is small and the attachment force to the fabric is strong.
(4) Printing dyes should have a bright color
