Overflow dyeing machine increases with temperature

Generally speaking, as the dyeing temperature increases, the dispersion of the dye and the kinetic energy of the diffusion into the fabric fiber also increase; at the same time, due to the expansion of the fabric fiber, the internal pores increase, which improves the absorption and diffusion capacity of the dye and accelerates the fabric. The dyeing speed. However, when the temperature is too high, because the fiber pores are too large, the kinetic energy of the dye particles is too large, but the dye that has been dyed on the fiber is partially re-dissolved in the dye solution.

The optimized design of the overflow dyeing machine and the reasonable configuration of nozzles, cloth guide pipes and cloth storage tanks make the fabric in a relaxed and unfolded state during the dyeing process under different liquor ratio conditions to achieve level dyeing. Disadvantages of the overflow dyeing machine: the result of dyeing may be that the dyeing effect of the cloth from each bar is different, and the four cylinders show a color from light to dark at the distance from the batching cylinder.
