what does "sublimated" mean?

It is about a Rash Guard (T-shirt) that is "sublimated".

How I say this word in Spanish ?

I didn't know the answer either, so I looked it up.  Here is what I found:

From http://www.blackduckonline.com:

"So, what is sublimation? Well, simply put, sublimation is a process by which sublimation dyes are printed onto a transfer medium with a specially prepared inkjet printer. Thereafter, those dyes are then transferred from the medium to an object or garment under the heat and pressure delivered by a commercial heat press. Sublimation only works on garments made of polyester, or on specialty objects made of polyester or given a polyester coating. When the heat and pressure are applied, the dye on the transfer medium sublimates, or becomes a gas, and is then absorbed into the polyester itself; the print is actually a part of the garment/coating. It doesn’t fade easily, wear, or have any texture or weight."

La palabra en español es "sublimado."  Este es un término de química, que quiere decir "transformar en un gas."  El término "sublimado" para una camiseta quiere decir que la tinta/tintura para la camiseta es en primer lugar impreso en un medio intermediario, y después transferido a la camiseta.  La tinta se transfiere a la camiseta por calentarlo en un gas, que se adhiere a la camiseta de poliéster.
