Can I use standard htv on this material

[Miss D]

Hi I have a customer wanting to know if its safe to apply normal heat transfer vinyl onto 36% polyester and 57% polyamide. This is her gym gear so would hate for it to go wrong. Thanks in advance

Hi Miss D, I don't know the answer, but I can say that Nylon is a Polyamide (everyone might already know that!)

Just thought someone might be able to help if they know the mix is Polyester and Nylon
