The short version: dye sublimation ink on transfer sheets, usually printed using an inkjet printer, is heat pressed onto the substrate. The ink is turned into a gas from the heat, and sublimates directly into the substrate. Consequently you can only use compatible substrates, which in the case of fabric means man-made fibres such as polyester.
The advantage is once printed, the ink is in the substrate, not sitting on top where it can crack, flake off, etc.
Historically the process was done via screen-printed transfer sheets, but these days is usually (maybe even always?) done via digital printing.
Other than that... you'll probably find a lot of info reading this section of the forums
