How big is the effect of temperature in high temperature dyeing machines
May 21, 2022
When using a high-temperature dyeing machine, the key is temperature. Properly increasing the temperature will effectively improve the dye uptake rate, but if the temperature of the dyeing machine exceeds 130 ℃, it will cause more disperse dyes in the There are obvious changes in the dyeing rate. The temperature in the dyeing process of the dyeing machine is not suitable for too high, so the temperature of the high-temperature dyeing machine will not exceed 145 ℃.
If the dyeing machine is dyed at an appropriate temperature, the leveling effect will also be very good. In order to ensure the quality of the dyeing, the heating rate should be controlled and strictly controlled. When the temperature reaches the specified range, the heat preservation can be carried out. For dyeing, ensure that the entire dye is fully penetrated and diffused. The dyeing time of normal insulation should be guaranteed within 30-60 minutes. If you want the color to be lighter, you can shorten the time a little bit. On the contrary, you want to dye deeper. When the dyeing is finished, the time should be adjusted accordingly. However, when the dyeing is finished, the cooling should not be carried out too quickly, otherwise there will be bad creases or the effect of affecting the whole feel.
