Heat Pressing on Dye Sublimated Fabrics

What is Dye Sublimation?

Most polyester fabrics, such as many of the popular “Performance Garments”, are dyed using a sublimation process. The dye of these fabric will migrate into the graphic after heat press. Many sporswear are made of polyester fabric.

Dye Migration Can Discolor Heat Transfer Appliques

When you heat press heat transfer vinyls onto a sublimated garment, the high heat will lead to dyes of the polyester migrate and discolor an applique.

In the photo above the white polyurethane vinyl turned a light grey after within 24 hours after heat press.
Dye migration does not occur at once when you heat press. Instead it happens gradually, which may take as long as 72 hours.

Two solutions provided by Kenteer to deal with dye migration 

1、Dye-block heat transfer vinyl

To avoid discoloration, our R&D department has developed an anti-migration layer to block dye migration. This layer of film prevents discoloration of an applique caused by dye migration.

Our heat transfer vinyl succeed at exacerbating the dye migration problem.

Dye-block heat transfers vinyls are suitable for numbers of sporswear.
