I want to make my own iron-on labels and patches (small scale, for fun).
Does anyone know what the name of the adhesive is? All I can find when I search online are people wanting to sell me pre-made patches, not information about their composition.
I presume it’s some low melting point (<100degC) polymer. For all I know a wide variety of things might work (maybe even PETG 3d printer filament, which softens around 70degC, or hot glue shavings), but I’d like to see if I can at least find out the name of what’s commercially used.
EDIT: Solved, see https://aussie.zone/comment/4326482
Hot glue works great for this. Especially the mini stick guns with smaller extruders. You can just put lines of it on the back of the patch and near the border. They can cool on the patch and then you can use the iron to heat them and glue them to the fabric.
