Precautions for high temperature and high pressure dyeing machine

1. Preparation of dye solution

When preparing the dye solution, first use a small amount of cold water to make the dye into a paste, and then use room temperature water to dilute it. Note that the temperature of the diluting water should not be too high, higher than 60 degrees, the dispersion dyeing quilt will be damaged, and the dye will be agglomerated. In addition to the preparation, it can also be prepared by the dusting method, that is, the dye is gradually sprinkled into cold water under high-speed mixing, and the dye bath should not be left for a long time after preparation. It needs to be gradually mixed with a mixer to avoid sedimentation.
