The use of high-temperature dyeing machines can well improve the overall dyeing rate of disperse dyes. However, there are many factors that will affect the use of high-temperature dyeing machines. The staff of the website share some main influencing factors for you. The first is temperature, The increase of temperature is very helpful for the improvement of the loading rate, but when the temperature is increased to a certain level, the dyeing rate will not change. Moreover, at too high temperature, the dyed fabric will have problems such as hydrolysis, which will lead to fiber degradation. The elasticity and strength will decrease, and the shade will also deteriorate. At the same time, higher temperature often means greater energy consumption, which leads to an increase in the dyeing cost of high-temperature dyeing machines. Therefore, we need to control the temperature reasonably. The use of auxiliaries It can also ensure that the dyes are smoothly dispersed into the dye bath and obtain a more uniform dyeing effect.
Auxiliaries can be appropriately added according to the needs. The pH also has a certain influence on the use effect of the high-temperature dyeing machine. Many disperse dyes are not easy to have any hydrolysis under alkaline conditions. Therefore, we need to reasonably control the pH of the dye bath. , to ensure better dyeing effect under threo acid conditions.
