Tips on jigger dyeing machine: operating precautions for high-temperature dyeing machine

1. Mix the dye solution. According to printing and dyeing equipment manufacturers, when mixing dye solutions, the dye should be mixed with a small amount of cold water to form a slurry, and then diluted with room temperature warm water. Please note that the temperature of the dilution water should not be too high, not exceeding 60 degrees, as it will damage the loose quilt. In addition to up-regulating the dye, the agglomeration can also be adjusted by the dusting method. That is to say, it should be mixed under high-speed mixing. The dye is slowly poured into the cold water and should not be kept for long after making the dye bath. To avoid settling, mix slowly using a stirrer.

2. When selecting and dyeing dyes, try to choose varieties with good diffusion and uniformity. When color matching, you should choose dyes with tight dyeing functions. ˆ

3. Restore and clean. Restorative cleansing is an important part of removing floating color. After restoration and cleaning, the color is slightly lighter. Fastness to rubbing together and to sunlight is improved. ˆ

4. Printing and dyeing equipment manufacturers introduce tar spots as viscous substances composed of dye solutions, mainly composed of dye laxatives and polyester oligomers. When polyester oligomer undergoes polyester condensation polymerization, it will exude from the fiber and flow into the dye solution during the long-term dyeing process at high temperature, thereby adhering to the fiber surface.
