Analyzing the DTF hot melt powder Application 

Hot melt adhesive powdered guns kill in the DTF transfer process by attaching the transfer film to the substrate and forming a better bond between them. In DTF, the process is initiated where hot melt adhesive powder is sprinkled onto a film on which a specific design is printed. Then, while in the curing or pressing stage, hot air is blown onto the adhesive powder pattern on the peripheral film, which is iron bonding, causing the pattern design to attach to the fabric to be printed. Padding this bond delivers outstanding durability, stretchability, and flexibility, allowing one of these super wear-resistant bonds to the garment’s fabric while also improving its washing and environmental resistance.
