WHAT IS HOT MELT POWDER?
DTF hot melt powder for DTF transfer inks and films is a TPU material that is soft and elastic to the touch and provides high adhesion. The powder is measured in GSM (Grams per Square Meter) and typically falls in the 120 range. This special adhesive powder is used for bonding materials like fabrics or textiles. More uniform particle the DTF transfer powder is softer the patterns on the garments. Its value lies in high durability, elasticity, water resistance, and superior cost efficiency compared to conventional adhesives.
A good powder should be safety-tested and certified with an OEKO-TEK passport, indicating no risk of air pollution or exposure to toxicity during the production/application process. Once melted down to a specific temperature range, this powder serves as a robust bonding agent for applications requiring lasting adhesion.
Hot melt powder melting point 105-132 °C
HOW DOES IT WORK
Direct to film transfers won’t apply without melting powder. Single-piece, small-run sheets, or direct-to-garment machine-printed DTF transfers can be applied by hand or with a dedicated powdering machine. In a production setting, a roll-to-roll powder machine is far more efficient. Printed images on a film roll are fed into a powdering station where the adhesive is applied to the wet print. The powdered film is then agitated to remove excess around the image and fed into a conveyor dryer for curing. The prints can wait a bit before powder application, allowing the ink to be tacky enough for a secure hold. Once the powder is dried to the print via heat, the printed transfer is ready to be pressed, stored, shipped out, or sold as a service.
The role of hot melt powder
DTF powder is incredibly versatile and can be used on various materials, including cotton, polyester, ceramics, and more. This versatility makes it a preferred choice for businesses involved in diverse printing applications
DTF Hot melt powder are specially designed to use with DTF Film Printing. Our DTF powders are slow drying and easy to cold tear. it is often used as a high-quality hot-melt adhesive in other industries. It is heated and melted in a highly elastic state at room temperature. Viscous fluid state in the later process, fast curing speed. This revolutionary technology will help you get excellent transfer printing results.
