Controlling drying temperature and time is the key

The base is rounded, because the fillet heat-set ink is easily fluid when it is melted at a high temperature, so that the ink flow penetrates into the gap of the cloth. When the ink cools, it forms an integral part with the cloth, which firmly sticks to the roots in the mud. The same reason can not be pulled out, but the right angle will not flow due to high temperature, so it is somewhat less fast, but because of this right angle performance, it can print a knife-like right angle effect, and rounded ink I can't do it.

We analyze according to the principle in the first article, if the ink is thinned or hardened with a thin plate, so that the ink is surely easier to enter the gap in the fabric, so using a thin plate to scratch the bottom of the ink or thinning the ink is beneficial to enhance the ink and The firmness between printed materials.

The drying temperature and time directly determine the success or failure of thermosetting ink printing. Thermosetting inks are thermoplastic inks. Resins and plasticizers are difficult to completely polymerize without reaching the temperature and time required by itself. The result is ink. The system is not very compact, but loose. Fingers buckle will appear as a little bit of powder, so let alone fastness. Some printing manufacturers dry the ink to the surface with a brightness. It is totally wrong to think of fastness. It is very easy to lighten. For example, if you use a firearm to blow at high temperatures for ten seconds, you have good brightness. However, this is the result of surface plasticization. In fact, it is not plasticized at all. Is simply no fastness, generally speaking high temperature thermosetting ink plasticization temperature of 180 degrees 3 minutes, medium temperature 160 degrees 3 minutes, low temperature 135 degrees 90 seconds, but different manufacturers of drying furnace may not be consistent, as well as the printed pattern of The thickness requirements for the barbecue are also different, so this data is only for reference.
