Energy saving and emission reduction in printing and dyeing industry of high temperature and high pressure dyeing machine

High temperature and high pressure dyeing machine This nozzle can provide enough dye liquor for the fabric during dyeing. The characteristics of the high temperature and high pressure dyeing machine design a new type of dyeing nozzle. At the same time, it can provide the unfolding power for the fabric during the operation of the fabric, so that the fabric is fully unfolded while running at a high speed in the rope shape, shifted from time to time, and released its internal stress, so as to minimize the color crease and dyeing phenomenon. The high temperature dyeing machine load is 300 kg per tube. This is unmatched by other dyeing machines. From the perspective of dyeing cotton, the process of adding salt depends on the shade and color sensitivity of the fabric. The salting process of the high temperature and high pressure dyeing machine is divided into adding salt before the dye is added and adding salt after the dye is injected. The former is suitable for dark products and colors that are not sensitive to salt. The salt can be quickly injected in a solid state; the latter is suitable for light For neutral and sensitive colors, salt needs to be injected quantitatively into the dye solution to circulate. The previous dyeing machine always dissolves the salt first and then slowly injects the salt when injecting the salt quantitatively. This takes a certain amount of time and affects the efficiency. For the first time on the tec series equipment, the function of overflowing salt is added to the quantitative tank, and it is optimized with the quantitative injection of the equipment and the main tank reflux function, circulation stirring function, direct steam heating function, and the ability to inject at 105°C. The dyeing results can increase economic benefits.
