[Solved] What is the name of the adhesive used in iron-on patches and labels? (aussie.zone)

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

Try to search "iron on fabric fuse" or "peel-and-stick fabric fuse"

Hmm. Could I be confusing two different products that look very similar?

I'm used to seeing "interfacing": a spun-woven fabric that has a shiny or dotted heat-activated adhesive on one side:

The "fabric fuse" ("hot melt adhesive web"?) that you're talking about might instead be this stuff, which looks very similar (it's still spun woven) but it has no glue on its surface, instead the fabric itself melts below ironing temperature?

If I'm not misinterpreting this second type: it might be exactly what I want :) I'll try and buy some.

EDIT: Yes it looks like this is the stuff! https://www.bostik.com/us/en_US/catalog/product/construction/nam/united-states/product-pe85/ Awesome, it's literally hot glue in a different shape. Thankyou so much uservoid1.

Is that stuff the same as Stitch Witchery?

Comparing the photos & description:

... I'd say they're probably similar. "Stitch Witchery" might just a brand of "hot melt web" AKA "spunwound hot glue" AKA "fabric fuse".

EDIT: They might be identical, but many plastics look identical and all plastics can have their melting point modified, so I can't say for certain.

Not sure if I'd bother.... That glue never holds anyway. I always iron on, then sew.

Good luck though, hope you find something.

Stretchy fabric? Hot machine wash?

[–] Hobart_the_GoKart@lemm.ee 3 points 1 year ago

I usually put them on denim that never gets washed. I think they just peel off from wear and flexing fabric.

Just web searched this, I don't know anything about it but maybe this would work.

Sorry, this page only has info about pre-made patches. It has nothing that names the adhesive chemical itself or information about how to make your own patches.
