Hi. I would be inclined to 'sacrifice' one of your shirts and see what happens. The sublimation will certainly work with the polyester component, but I have the feeling that it will possibly wash out of the rayon part and give the same faded look you get with poly cotton mixes. Could be wrong though, so I'd be inclined to give it a blast.
I have not had a problem with fading. Is it possible that the paper that transfers the ink is a factor? I have only used certain dyesub transfer paper and maybe I have just been lucky....
I have used many materials like rayon and nylon and found that they do ok but lack the pop
of polyester. You may need to back off the temp to say 375 at 40 seconds. One client of
ours is big into umbrellas (nylon).

Hi David, glad to see you on the forums. I know you were always so much help when I called with a question. You say nylon, does that mean I could sublimate the back packs that are 100% nylon?
Rayon is a cellulose fiber (not a synthetic fiber) and will perform just like cotton when it comes to dye sublimation, if there is some polyester in the blend the poly will take the color and hold it, rayon will not. Nylon )and poly amides in general) will take sublimation ink however the dyes will "migrate" within the fibers over time and you will get poor wash and rub fastness.

Hello, i'm from romania and I just bought an epson stylus sx 115 with ciss adaptor and heatpress machine, and wanna make some fine good t-shirts,but only a problem, here we have only 3-4 distribuitors of heattrasferpaper and they all told me that the paint will last only 10 washes... and also they don't know what kind of sublimatioan paint do i need, it's so wierd they are a little slouch... anyway, please can someone tell me if there's a much stronger durable paper than chromablast? and what kind of ink do i need?
now i have dye ink, and want to make printing with any kind of ink or paper,just tu last longer, on bumbac t-shirts,white, is it possible? thank you for your time, felix www.bindiribli.ro if you wanna join or see ,thanks
