The blue specs are easily avoided if you lint roller the shirt prior to pressing.

Tultex has a 65/35 for men and women. Mostly heather colors though. It's okay, too light for my tastes. Here's a link:

the best t shirt which I have had experience with when it comes to sublimation printing is XPRES tee - it has a 100% cotton inside (to keep in contact with the body) and 100% polyester surface (for the subli dye) - its a double knit fabric so you get the best of both worlds

Rayon is made of cellulose fibre. It's neither natural or synthetic fabric. It is so-called semi-synthetic.
I have printed on poly/rayon blends only a couple of times - the result was a little better than poly/cotton and worse than just poly.
The fabric you are reffering to is essentially only 50% polyester, so you can expect a very "distressed" and faded look; however, it will be marginally better than 50/50% poly/cotton.

Gildan and Next Level Apparel has 65 poly and 35 cotton shirts for men and women. They work out to be pretty good. Gildan is around $3.00 and Next level Apparel is around $3.50. Next Level has more choises but Gildan shirt is more heavier.

Lint. Use a sticky lint roller on the shirt before pre-press. That'll take care of it.

I've had pretty good success printing on poly cotton 50/50 this past week.
I press my shirts before sublimating, and have had great results producing pretty vivid color, but of course cannot achieve a full black, more like a 70% grey.
I set my temp at 400 and let it cook for a minute, sometimes i leave it in an extra few seconds. My paper gets thoroughly toasted, and releases MUCH of the dye to the garment without burning them.
sorry, forgot to add, most of the shirts i printed on were from next
white, and heather grey

Hi All
I'm using an 80/20 poly cotton blend on continuous printing at 206deg C and I'm still getting these blue marks. what can I do ?

Adding to your point, if the blue specs are not there on the material coming from the factory then they are happening because the t-shirt actually has an electrical charge and is attracting debris from the air.
Moist air the particles floating around are heavier and tend not to float around as freely and fall to the ground eventually. Dry air is more conductive to electrical charge.
Polymer is a plastic and plastic can develop a charge. If you pre-press a Poly t-shirt the pressure and temp can also "charge" a t-shirt that is essentially a plastic.
Pulling a poly t-shirt out of hot dryer you can get a good idea how much charge the shirt can have.
An evap type cooler can add moisture to the air as can a vaporizer.
