DTF powder, also known as hot melt powder, is an essential adhesive in the DTF (direct-to-film) printing process. It plays a crucial role in bonding the ink-printed image to the fabric. Selecting the right DTF powder is not only about achieving the desired printing effect but also directly impacts the quality and durability of the final product.
Based on texture and application, DTF powders can be categorized into various types, including fine powder, medium powder, coarse powder, and special function powders such as Solid Lock DTF powder and anti-sublimation DTF powder.
Fine DTF Powder (0-80 microns): Ideal for printing on delicate fabrics and scenarios requiring high-precision patterns, like small wash labels, tags, and high-end custom clothing. It provides a smooth touch but may have reduced fastness in high humidity.
Medium DTF Powder (80-170 microns): The most popular choice, suitable for various common apparel fabrics like T-shirts, hoodies, and sportswear. It has a granular texture, easy to shake and clean, offering a moderate hand feel.
Coarse DTF Powder (120-240 microns): It is suitable for fabrics with coarse texture, such as rough cotton, linen, canvas or denim. The gap is large, it is easy to shake the powder clean, and the three-dimensional effect is strong.
Different fabric types have varying compatibility with DTF powders. Choose based on the fabric's material, elasticity, and color.
White DTF Powder: Suitable for fabrics of any color, ensuring vibrant and clear prints. Especially good for light-colored fabrics, providing excellent adhesion and opacity.
Black DTF Powder: Ideal for dark textiles, preventing color sublimation and enhancing color depth and vividness. Primarily used for dark colors or fabrics requiring anti-sublimation properties.
When selecting DTF powder, consider key characteristics like adhesion, activation temperature, and wash fastness.
Adhesion: Ensure the powder firmly bonds the ink to the fabric upon heating, creating a durable print.
Activation Temperature: Choose a powder with an activation temperature compatible with your printing equipment and process for effective bonding.
Wash Fastness: Excellent wash fastness prevents pattern fading or wear, extending the fabric's lifespan.
Environmental considerations are vital in today's printing industry. Opting for eco-certified brands helps reduce environmental impact and promote sustainability.
To maintain the quality and performance of DTF powder, follow proper storage and usage guidelines.
Storage: Keep the powder in a sealed container, stored in a cool, dry place, away from direct sunlight and moisture.
Usage: Wear protective gear, ensure adequate ventilation in the workspace. Read the product manual thoroughly before use and follow the recommended methods and steps.
Finally, when deciding on a DTF powder, comprehensively compare different brands based on price, quality, performance, and after-sales service. Ensure the powder is compatible with your printer and fabric type, considering its durability and ability to withstand multiple washes, to find the most suitable solution for your needs.
By understanding the different powder types, considering fabric types and colors, evaluating powder characteristics and functions, focusing on production sustainability, and adhering to proper storage and usage methods, you will be able to select the optimal DTF powder for your requirements, achieving the best printing results.
