I've had some questions about this so I'll do a thread about decorating polyester! It's nothing too complicated, but if you don't know what you're doing, it's going to come out like this. 1/? https://twitter.com/F1sT/status/1310235750169022465

First up, that's a 100% polyester hoodie. Usually you choose poly when you know the garment will get wet/sweaty when using it. They're roughly the same price as cotton, but you can't do a lot with poly to make it nicer like you can with cotton (or blends especially). 2/?

Polyester is "plastic" (it's complicated) and it's not an absorbent material, which is why you use it when it will get sweaty, so it doesn't stink. This makes it harder to screen print on, since water based inks won't stick. So you need to do Heat Transfers or use Polyester inks.

I see people in the comments saying "lol just dtg bro" but you can't DTG polyester. You can dye sublimate, but not DTG (direct to garment printing). In either case, you wouldn't use either method for this print, as it's only a couple colors and not a complicated print. 4/?

Look at how the red ATLANTA peeled up, this very likely is a heat transfer gone wrong. Heat Transfers are just like you do at home with your iron, but with a much bigger heat press and specific instructions on how long/hot to hold the press. They just didn't follow directions 5/?

You order the heat transfers from one of the big makers (Stahl's, etc) and they come in and you apply them, but even then it needs to be the right materials. This looks like everything was wrong. 6/?

Moving to the black FAZE logo. I can't tell if that is a transfer or not, but in either case they used the wrong kind of ink. See how it's breaking up/coming apart? That means that they didn't use polyester inks. There are different inks that work here, plastisol (contd) 7/?

is a good choice here, especially for the very solid/bulletproof prints that modern streetwear designs want to use (HEAVY prints you can feel). Not sure if they just didn't apply enough or didn't heat/dry it enough, but that's a disaster. That would get rejected on the line. 8/?

You need to go super heavy, but also treat them well because otherwise they will crack if you ball them up. It's why you hang your hypebeast shirts. They did not do that here, that looks super thin and also no underbase (???)

Typically if screen printing, you put an underbase under the ink so that it sticks better and looks better if it does crack years later. Doesn't look like that was done here. So maybe it is a transfer, in which case the wrong ink was chosen and it's just falling apart.
