Different Types of Heat-Away Stabilizers.
There are two main types of heat dissolvable stabilizers. They are both very similar, and can be used in the same projects, but have a couple of different features.
Heat-Away Brush Off Stabilizer
Heat-away is a special heat-sensitive woven fabric that is like muslin that disintegrates with heat from a hot DRY iron then brushes away easily. It may be used on either side of your fabric. It turns brown with the heat from your iron. It brushes away very easily. Sulky heat-away is easy to see through so you can trace designs on to it for easy stitching. Perfect for any project where wetting or tearing would cause distortion to stitches or damage to your base material. Because it is woven and firm, it is easy to stitch on when creating machine arts. The stabilizer is not compatible with liquids.
Melt-Away or Embroidery Trick Film
Melt-away is also known as embroidery trick film. It is a plastic, perforated stabilizer that grips the fabric, and can be either torn or melted away. Melt-away has a rough surface that grips the material, preventing slippage when sewing on it.
It is great when used as a topping when embroidering on fabrics with pile, as only the excess is melted away with the iron. This means the hidden melt-away will remain permanently between the embroidery threads and your fabric. This stops the stitching from sinking into the embroidered item even after many washes.
Melt-away is a transparent film that does not show through the fabric. It's easy to use, it doesn't pucker, doesn't shrink and won't change the colour of your fabrics. It is only 0.07 thick, which allows the fabric to fall naturally without a heavy appearance when used as a stabilizer. When using meltaway as a backing you don't always need to iron the residue, simply tearaway as you would with a tearaway backing and leave in place.
Melt-away can be easily removed or melted away with an ordinary non-teflon household iron - 120o C/230o F. Unlike heat-away, you MUST use brown paper between the iron surface and the melt-away plastic. The brown paper can be re-used as the melt-away will peel off the paper.
