If someone should say "but that isn't sublimation", then tell them to go educate themselves. LOL
usually said in response to applying print to cotton etc. Sublimation mean to heat at such a high temp that a solid become directly a gas. This has nothing to do with the fabric. However the dyes do not adhere to cotton and so another 'material' is used, but still goes through the state of sublimation. I'm not a big fan of applying sublimation print to cotton, but I am against poor facts being used.
Sublimation refers only to the reaction of the dyes, but yes once the dyes are a gas they can only 'bond' with polymers. the term 'sublimation' is not in reference to any single fabric, but our dye-sublimation inks are.
