How Does the Blocker Layer Work?
Our Blocker Transfers contain two smart layers:
- Carbon Layer: Acts as a molecular sponge that absorbs migrating dyes
- Barrier Film: A physical layer that prevents the dye from breaking through
This technology is derived from industrial filtration and perfectly adapted for textiles. That’s why your whites stay truly white – even weeks later.
