I have seen some similar topics but nothing that is exactly my issue, so hopefully someone can help.
I am having issues with Siser easyweed stretch adhering to sweatshirts. The Shirts are Gildan G185 ( I washed them first with a mild detergent, NO fabric softener, to eliminate the shrink factor). I pressed the easyweed stretch using firm pressure in my clamshell press at 305 (which I triple verified using an infrared heat gun) for 15 seconds. I let the vinyl cure for over 24 hours, and after washing inside out according to the instructions, I get wrinkling and peeling. I’m at a loss, and don’t know what is going wrong. Is it possibly that I shouldn’t use easyweed stretch on cotton blend shirts? I used the same vinyl on a polyester moisture wicking shirt and had absolutely no issues.
