The Essential Guide to DTF Hot Melt Powder for Perfect Transfers
2026-01-16What is DTF Hot Melt Powder?
DTF Hot Melt Powder is a thermoplastic adhesive, applied as a fine dust to the wet ink printed on a PET film. After printing with a white underbase and colors, the powder is evenly distributed using a powder shaker or manually. When this powdered film passes through a heat press, the powder melts, creating a strong, flexible adhesive layer that permanently bonds the design to the garment upon cooling. Without this powder, the DTF transfer process cannot be completed successfully.
Key Properties of Quality DTF Powder
A superior DTF powder, like those compatible with a Fedar DTF printer system, offers a suite of essential properties for professional results:
Temperature Resistance: Performs consistently in a wide range, ensuring stability during the hot-press transfer and throughout the garment's life.
Chemical Stability: Resistant to water, acids, alkalis, and corrosion (oxidants, oils), preserving the print's integrity.
Soft Hand Feel: When melted and cured correctly, it creates a flexible adhesive layer that maintains the fabric's drape and comfort.
Choosing the Right Powder for Your Project
Selecting the correct powder type is as important as using a reliable Fedar DTF printer. Powders are categorized by particle size and specialized additives to match different fabrics and effects:
Soft Powder (80-170μm): Ideal for smooth fabrics like T-shirts and polos, providing a soft, seamless finish.
Coarse Powder (120-250μm): Designed for textured materials like denim, canvas, or linen, offering a stronger bond for rougher surfaces.
Anti-Stretch Powder: Formulated for elastic fabrics, maintaining adhesion and preventing cracks on stretchy materials.
Anti-Sublimation Powder: Essential for dark garments, it acts as a blocker to prevent the underlying fabric color or pattern from showing through the transfer.
Quick-Peel Powder: Enables immediate peeling of the film after pressing (hot peel), significantly speeding up production workflow.
Storage and Best Practices
To maintain performance, DTF powder must be stored in a sealed container in a cool, dry environment. Exposure to humidity causes clumping, leading to uneven application, poor adhesion, and flawed transfers—issues that can undermine the quality output of even the best Fedar DTF printer.
