Anti-Shedding DTF Hot Melt Powder | High Adhesion, Even Application, Improves Yield
Frequently Asked Questions
Q: What is the difference between PA powder and PU powder? Which one should I choose?
A: PA powder (Polyamide) has the strongest versatility and strong adhesion, making it suitable for most fabrics. It is the preferred choice for beginners and mass production. PU powder (Polyurethane) is softer, with excellent elasticity, specifically designed for high-elasticity fabrics (such as Lycra sportswear and swimsuits) to prevent cracking. If you mainly print on regular T-shirts and sweatshirts, choose PA powder; if you specialize in elastic fabrics, choose PU powder.
Q: Why do the edges of the pattern sometimes have "excess glue" or unclear contours after the powder melts?
A: This is usually caused by three factors: The temperature is too high, causing the adhesive to flow too much; The powder is too thick, requiring adjustment of the powder amount; Too much pressure during heat pressing. It is recommended to conduct a small test sample to precisely control temperature, powder amount, and pressure.
Q: Can the powder still be used if it has clumped due to improper storage?
A: Slight clumping can be remedied by manually massaging and sieving through a 100-mesh screen, though its performance may slightly decrease. If the powder is severely clumped or moisture-damaged, it is recommended not to use it, as moisture can cause uneven activation and severely affect adhesion strength. Be sure to store it sealed in a dry environment.
Q: Can this powder be used with any brand of DTF ink?
A: Yes. This product is based on a physical bonding principle and is compatible with most water-based pigment DTF inks on the market. However, to ensure the best results, it is recommended to use the powder with inks and pretreatment solutions from the same brand/system, as the system performance has been tested for compatibility.
Q: Do I need to switch to "high white powder" when printing on dark fabrics?
A: Not necessarily. Transparent powder is suitable for all situations, relying on the white ink layer to cover the fabric color. High white powder adds titanium white pigment to the transparent powder, providing extra opacity and is suitable for: Extremely dark fabrics (e.g., pure black); When you want more vibrant and saturated colors; When the white ink layer may be too thin. In regular cases, transparent powder is sufficient.
Q: How can I determine if the powder amount is correct?
A: A simple visual standard: after the powder melts and cools, the pattern area should show a uniform matte or slightly glossy film, with no visible fabric texture. If the fabric texture is still clearly visible, the powder amount is insufficient. If the film layer is too thick and has a raised, three-dimensional feel, the powder amount is too much.
