What is DTF Powder and Why Does It Matter?
DTF powder (hot melt adhesive) is a special adhesive material applied to printed images on DTF film before transfer to fabric. Under heat press temperature, the powder melts and creates a strong bond between the print and fabric. Without DTF powder, image transfer to textiles is simply impossible.
How DTF Powder Works
- Image is printed on DTF film using a DTF printer.
- While ink is still wet, DTF powder is evenly applied.
- Excess powder is shaken off — it sticks only to inked areas.
- Film passes through a shaker dryer to melt and fix the powder.
- Transfer is applied to fabric using a heat press at 160-170°C.
Types of DTF Powder
By Particle Size
- Fine (80-100 µm). Ideal for detailed images. Smooth print surface.
- Medium (100-150 µm). Universal option for standard prints.
- Coarse (150-200 µm). For large images and dense fabrics.
By Color
- White powder. Most popular, universal for all fabric colors.
- Black powder. For special applications on dark fabrics.
How to Choose DTF Powder: 7 Key Criteria
- Particle size. Fine for detailed prints, medium for general use.
- Adhesion. Quality powder withstands 50+ wash cycles.
- Elasticity. Adhesive layer should remain flexible after melting.
- Flowability. Should be free-flowing without clumps.
- Compatibility. Must work with your inks and DTF film.
- Safety. Use with proper ventilation in well-aired spaces.
- Manufacturer. Trusted brands ensure batch-to-batch consistency.
Application Methods
- Automatic.Shaker dryers automatically apply and fix powder — best for business.
- Manual. For small volumes — sprinkle evenly and shake off excess.
Apply immediately after printing, ensure even coverage, shake off excess thoroughly, dry before storage.
Storage Guidelines
- Store in airtight packaging — powder is hygroscopic.
- Temperature: 15-25°C, humidity: below 50%.
- Don't mix different powders.
- Shelf life: 12-24 months sealed.
Common Mistakes
- Too much powder — rough, stiff print.
- Too little — print peels off after washing.
- Humid storage — clumping, uneven application.
- Wrong drying temperature — powder won't fix or spreads too much.
Powder Consumption
- A4 print: ~5-10 g. A3 print: ~10-20 g.
- 1 kg covers approximately 100-200 A4 prints.
Conclusion
DTF powder is an essential part of DTF printing technology. Proper selection, storage, and application are the three pillars of successful DTF production.
