Do Fabrics Need To Be 100% Polyester For Dye Sublimation Printing?
What you may not know is how this process works and why polyester
fabric is the best product for dye sublimation, whereas cotton, wool, and even
nylon will not work for this type of printing. While you do need at least 60%
polyester fabric to successfully dye sub print, it is better to use 100%
polyester because you will attain a superior print if 100% of the fabric
accepts the dye when it enters gas form and is inducted into the open polymer pores.
Starting with the dye, it is necessary to know that the dye is not
the same type of ink as inkjet inks which use the CMYK
(cyan-magenta-yellow-black) ink set, but instead, use a CMYO dye set
(cyan-magenta-yellow-overprint clear) where the clear, when it is printed on
the dye sublimation transfer paper, turns to black and transfers that way.
Once the paper is printed, it is joined, print side to whichever
type of material you are using, then put through a set of heated rollers. The
heat must be in excess of 370º F (190ºC) to cause the dye to be converted into
a gaseous form, and also to cause the polymer's cells to open as they expand to
accept the now gaseous dye into the cells.
Once this process has taken place, the fabric cools, the cells
close, and the color is permanently locked into the fabric in continuous tones
of beautiful color, similar to a photograph's tones. Without the cellular
construction of the polyester fabric and its polymeric qualities, it would not
be possible to print using dye sublimation. So, the more polymers, the better.
So the answer is, of course, yes and no. We recommend using 100% polyester, but
it's not an absolute requirement.
