Influencing factors of high temperature dyeing machine

The use of high temperature dyeing machine can greatly improve the overall dye uptake rate of disperse dyes. However, there are many factors that affect the use of high temperature dyeing machines. The staff on the website will share some of the main influencing factors. The first is temperature , The increase in temperature is very helpful to increase the loading rate, but when the temperature rises to a certain level, the dye uptake rate will not change. However, the dyed fabric will have hydrolysis and other problems at an excessively high temperature, resulting in The elasticity and strength of the fiber will decrease, and the color will become worse. At the same time, higher temperatures often mean 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 Dye can also ensure that the dye is stably dispersed in the dye bath to obtain a more uniform dyeing effect. So we can add additives appropriately according to the needs. The acidity and alkalinity also have a certain effect on the use of high-temperature dyeing machines. In alkaline Under the conditions, many disperse dyes are not good for any hydrolysis. Therefore, we need to reasonably control the pH value of the dye bath to ensure better dyeing effect under acidic conditions.
