The grey cloth 10 without the redundant dye liquor passes through the first air blowing mechanism, and the first air injection pipe 51 in the first air blowing mechanism performs high-speed forced air blowing on the cloth surface of the grey cloth 10, so that the cloth surface with the dye is quickly and uniformly oxidized to realize the color changing process. After the process is repeated and dyeing is carried out repeatedly, the color of the finished product cloth surface is deep and uniform, and the problem of color difference caused by the change of the liquid rate of the cloth surface can be avoided. Moreover, the dyeing process of the fabric can be completed in a short time by the jig dyeing device, and the whole device does not need a large floor area for ventilation and oxidation.

Specifically, the trough 2 is provided with a cloth guide roller 22, and the raw cloth 10 fed from the first winding mechanism 1 is wound around the cloth guide roller 22 provided in the trough 2. The trough 2 has enough width and length, so can ensure that after the grey cloth 10 is dyed by the trough 2, redundant dye liquor on the grey cloth 10 can fall into the trough 2 when falling downwards, so as to realize the recovery of the dye liquor and save the using amount of the dye liquor.

As shown in fig. 1, a heating unit 21 for heating the dyeing liquid may be provided in the tank 2, and the heating unit 21 may maintain the dyeing liquid at a suitable temperature to ensure the dyeing quality. The heating unit 21 may be a heating pipe, which is disposed in the dye liquor when the dye liquor is contained in the trough 2.

The pressure difference of each position of the first rolling mill roller 41 in the width direction of the grey cloth 10 to the grey cloth 10 needs to be within +/-2%, so that the degree of squeezing and rolling each position of the grey cloth 10 in the width direction can be effectively guaranteed to be basically the same, the liquid carrying rate of the cloth surface of the squeezed and rolled grey cloth 10 is basically the same, and large difference cannot occur. For dye such as indigo dye which needs to be oxidized and discolored, the first rolling mill roller mechanism 4 can control the liquid ratio of the cloth surface of the gray fabric 10 squeezed and rolled by the first rolling mill roller 41 to be between 65% and 110%, and the appropriate liquid ratio of the cloth surface is controlled, so that the degree of oxidative discoloration during blowing can be controlled later.

For the dye such as indigo dye which needs to be oxidized and discolored, the second rolling mill roller mechanism 7 can control the liquid ratio of the cloth surface of the gray fabric 10 squeezed and rolled by the first rolling mill roller 41 to be between 65% and 110%, and the appropriate liquid ratio of the cloth surface is controlled, so that the degree of oxidative discoloration during blowing can be controlled later.

In a preferred embodiment, the second rolling mill roller mechanism 7 is not too far from the level of the dye liquor in the vat 2, and it is necessary to ensure that the leuco dye liquor squeezed out by the second rolling mill roller mechanism 7 is in a non-oxidized state before it flows back into the vat 2.
