RF polymer welding machine.Fabric hot stamping operation process

　　1. Choose a 33T-40T screen and print the hot stamping paste twice on the fabric (the screen is about 80um thick, and the curing agent should be added in a 2-3% ratio depending on the adhesion requirements, but the silk screen should be completed within 6 hours after adding the curing agent, otherwise it will affect its adhesion).

　　2. After printing the paste, bake it in an oven at 150 ℃ for about 5-10 minutes (for fabrics with low water absorption, the paste can be made slightly thicker to prevent sticking, but if it is too thick, it may clog the mesh), and the hot stamping paste should be dried thoroughly.

　　3. If it is flat hot stamping, the hot stamping temperature/time should be controlled at around 150 ℃/20 seconds, and the hot stamping pressure should be above 4kg. If it is hot stamping, it should reach around 180 ℃. The hardness of the silicone roller is 90 degrees, and it can also be hot stamping with a metal plate separated by a cloth. After ironing, it can be packaged.

　　4. The testing time should be selected after 72 hours. The products that have been hot stamped fully comply with international standards: machine wash with 60 ℃ warm water and laundry detergent for 30 minutes without fading.
