What Is DTF Powder and Why Is It Essential?

DTF powder is a hot-melt adhesive powder implemented over moist DTF ink on the PET movie. It is critical for the transfer technique.

Key Functions of DTF Powder:

  • Adhesion: Bonds the ink to the garment fibers all through warmness urgent.
  • Durability: Provides wash resistance, stopping the print from cracking or peeling.
  • Flexibility: Ensures the print stretches with the fabric.

A: Store inks in a cool, dark location and powders in airtight containers to prevent moisture absorption.


Q: Can DTF ink be used with out powder?

A: No, powder is vital for the adhesive bond in the course of warmth pressing.


Troubleshooting Common Issues with DTF Ink and Powder

Cause: Insufficient drying time earlier than powder application.

Solution: Allow ink to dry or cure properly before making use of powder.

- Powder Not Sticking Properly

Cause: Applying powder to dry or cured ink.
