Chemical operation points and dyeing conditions of high pressure rapid jet dyeing machine
Jan 04, 2019

The high-pressure rapid jet dyeing machine should be accurate according to the dyeing materials prepared by the kitchen single-check. When dispersing the dyeing materials, it is generally firstly beaten with cold water, and then used 40-45 °C warm water to make it evenly. Dispersing agent and ammonium sulfate are mixed with warm water and mixed. In use, alcohol or pull powder solution can be used to make a slurry, stir well in cold water, and dilute with warm water.

 

When the high-pressure rapid jet dyeing machine is used to dye the chemical, it must be filtered with a sieve, and the small particles remaining in the sieve should be re-watered and filtered. The feeding sequence is about 40 ° C, acetic acid is added, the operation is for a while, the pH is adjusted to 5-6, the dye is added, and after running for 10 minutes, it is dyed according to a predetermined heating curve. If the foam is found in the machine after feeding, in order to avoid damage to the circulation pump, reduce the lift or even float the fabric, defoaming agent should be added in time to defoam.

 

When the high-pressure rapid jet dyeing machine is dyeing, the cover should be closed before the temperature rises, and the operation of the grey cloth in the machine can be observed from the glass visual hole at any time, and the abnormal sound and phenomenon of each part of the machine are checked. At 50 to 60%, the disperse dye is dyed very slowly or substantially without dyeing. When the temperature is above 80%, the dyeing speed is increased. Therefore, the temperature rise between 80 and 130 °C should not be too fast.
