If your vinyl isn't sticking, you can use heat to affix it better. Use a hairdryer or heat gun on the surface of the self-adhesive vinyl while applying it to your desired surface. Using heat will help it conform to any uneven surfaces a little quicker.
The ideal temperature to use for heat transfer vinyl is between 260 ℉ to 315 ℉ (130 ℃ to 160 ℃) using medium pressure. It's important to read the product description of the heat press product before doing any work.
Heat can damage the vinyl and it may not stick properly. In any case, it will look like a sticker on top of your t-shirt and will come off or get damaged in the first wash. Permanent vinyl is not designed to adhere to any fabric.

Not pressing long enough will not provide sufficient time for the heat to activate the adhesive. Conversely, pressing for too long risks burning vinyl and the garment.
Techniques like using transfer tape and applying heat enhance the vinyl's ability to stick properly. Transfer tape helps in the accurate placement and alignment of the vinyl, while heating the vinyl makes it flexible enough to fit into the textured surface's unique contours.
All vinyl has a maximum outdoor life. It is quite possible that the vinyl you see peeling has reached its maximum lifespan and is beginning to fail. If this is the case, it's time for the old vinyl to be removed and new vinyl to be installed.
If it doesn't stick, check the heat press to make sure the actual temperature is what's displayed. Let it cool for a few more seconds, or use a little more pressure.
While waiting for your vinyl to cure for 72 hours is essential, you can also consider heat-setting your design.

Shrinkage: Vinyl may shrink when exposed to high temperatures for an extended period. This may result in the vinyl no longer fitting the surface properly. Surface Damage: Overheating can damage certain surfaces, especially sensitive materials.
Permanent vinyl has a stronger adhesive and is meant to hold permanently. You can remove permanent vinyl, but it will likely damage whatever it is attached to, like a wall, laptop, or car.
