Heat transfer vinyl has a heat-activated backing, which can activate between 160-190C depending on the brand and type.
You can cut this HT vinyl with a vinyl cutter, remove what you do not want, and either apply it to your material by using a heat press or simply using an iron.
It is also possible to layer (add different colours on top of one another), except no layering on Flock.
HT vinyls are available in many different colours and types. Our main types of HT vinyls are Smooth, Glitter, Flocked (velvet-texture), and Metallic.
Important info: HT vinyl is not just for fabrics, it can also work with any substrate that can withstand a minimum temperature of 160C applied to it for more than 10 seconds.
Some examples of other substrates you can apply HT vinyl to are mugs (use with mug press machine), wood, leather, etc.
Only when using Printable HT, you would need to use Application film to transfer your cut image. Solid colours do not need application tape since most already have a Removal backing material that needs to be removed while hot or cold (depending on the usage instructions).
