We pressed uniforms for a team and used digicut pro vinyl and it on a dazzle cloth uniform. Polyester but with a dazzle finish. pressed them and they looked great, but after a wash or two the letters started to peel up. We followed the recommendations for the vinyl as far as heat and pressure. If I recall it was 305 for 30 seconds. Why would they peel. Should we use a higher temp.... any help would be greatly appreciated.
I recommend you contact the company that sold you the product.
