What is the relationship between Yarn Package Dyeing Machine and temperature

If the temperature of Yarn Package Dyeing Machine is properly raised, it will effectively improve the dye uptake of the entire dispersed dye, but if the temperature of the high-temperature dyeing machine exceeds 130℃, it will cause more Disperse dyes have a very obvious change in the dyeing rate, so the temperature during the dyeing process is not suitable for too high. If the temperature is too high, the polyester ester bond may be hydrolyzed, which will eventually lead to the strength and elasticity of the fiber. There will be a serious decline in the color and light, and the color will also be affected. Therefore, under normal circumstances, the temperature of the high-temperature dyeing machine must not exceed 145 ° C. The normal temperature should be guaranteed between 125 ° C and 130 ° C. If it is ensured that the dyeing process is carried out between the appropriate temperatures, not only the color yield will be higher, but also the leveling effect will be very good. In order to ensure that the fuel can be more uniformly absorbed by the polyester, it should focus on the control. The entire heating rate is strictly controlled

When the temperature reaches the specified range, it is better to carry out heat preservation dyeing. The Yarn Package Dyeing Machine ensures that the entire fuel can be fully diffused or penetrated. The normal heat preservation dyeing time should be guaranteed within 30-60 minutes. If you want to If you want a lighter color, then shorten the time a little bit. On the contrary, if you want to dye darker, adjust the time accordingly, but when the dyeing is over, remember not to overdo it. Cool down quickly, otherwise there will definitely be bad creases, or it will directly affect the final effect of the entire feel. The key temperature in the use of high temperature dyeing machines.
