HT Jigger Dyeing Machine dyeing problem

1. Mix the dye solution. When printing and dyeing equipment manufacturers introduce mixing dye solutions, they should first mix the dye with a small amount of cold water into a slurry, and then dilute it with room temperature warm water. Please note that the temperature of the dilution water should not be too high, it should not exceed 60 degrees, and it will damage the loose quilt, and the agglomeration can not only increase the dye, but also can be adjusted by dusting. That is to say, it should be mixed under high-speed mixing. The dye is slowly sprinkled into the cold water and should not be stored for a long time after the dye bath is made. In order to prevent sedimentation, it is necessary to use a stirrer for slow mixing.

2. When selecting and dyeing dyes, try to choose the types with good dispersibility and uniformity. When matching colors, choose dyes with tight dyeing function.  

3. Rehabilitation and cleaning. Rehabilitation cleaning is an important part of removing floating colors. After recovery and cleaning, the color is slightly lighter. The fastness to conflicts and sunlight is improved.  

4. Introduction of printing and dyeing equipment manufacturers Tar mottle is a viscous substance composed of dye solutions, mainly composed of dye laxatives and polyester oligomers. When the polyester oligomer undergoes polyester polycondensation, it will ooze out of the fiber and flow into the dye solution during the long-term dyeing process at high temperature, thereby adhering to the fiber surface.
