Although dyeing with low bath ratio dyeing machine has many advantages, there are many difficulties in realizing small bath ratio dyeing. The lower the bath ratio, the greater the risk and difficulty of dyeing. It is required that the solubility and stability of dyes used in small bath are better than those used in dyeing. Especially when dyeing dark varieties and multi-dyes are mixed, the dependence of different dyes on bath ratio is different. The contradiction between solubility and stability of dyes is mainly reflected in the dispensing tank, because the concentration of dyes in the dispensing tank is much higher than that in the dyeing tank.

Another difficulty in low bath ratio dyeing machine is leveling, which requires good dye circulation and application equipment of the dipping equipment. On the basis of guaranteeing the dyeing quality, the bath ratio is 1:5 to 1:4, which makes the formula cost, steam consumption and water consumption significantly reduced, and the consumption of uniform dyeing process with different bath ratio is compared. With the ratio of 1:12 bath consumption to 100%, steam consumption at 1:4 is 23.8 kg/kg fabric, the cost of process formulation is 25.4%, and water consumption is 33 L/kg fabric. It can be seen that the energy saving, consumption reduction and emission reduction of small bath ratio are obvious.
