When using DTF ink powder heat transfer film, the surface with the ink-absorbing coating should be the printing surface. Care must be taken in handling, and attention should be paid to the anti-scratch ink-absorbing coating. After printing, bake for 40-90 seconds, and choose 60-80 mesh hot-melt powder to achieve instant tearing, with 100-150-mesh hot-melt powder recommended for warm tearing or cold tearing, and hot-melt powder above 150 mesh recommended for cold tearing. Store the film in a dry place, paying attention to moisture.
DTF ink powder heat transfer film is a digital printing ink-absorbing PET film that is suitable for digital transfer printing. The pattern obtained after ironing has a texture akin to PU glue, offering strong stretch resilience without deformation and a softer feel compared to glue. It is compatible with most inks in the market, allowing for 100% ink printing at will without ink accumulation or flow. The film’s surface is dry and can be sprinkled with 200-mesh ultra-fine powder without sticking, making it easy to apply hot, warm, or cold tips.
It is important to note that if the baking temperature is too high or the baking time is too long after printing with hot melt powder, white spots may appear on the surface of the pattern. This is due to the slow drying agent in the ink, which forms a film after the hot melt powder is heated and cannot be volatilized. After the gas is cooled, it forms mist crystals on the surface of the pattern. This whitening phenomenon will gradually disappear after several days of storage and contact with air and will not affect the beauty of the pattern in the later stage.
The transfer pressing temperature is 140-160 degrees, 6-10 seconds, according to different meshes of hot-melt powder, and the most suitable temperature zone for the fabric can be adjusted to easily achieve hot tearing.
