[0007] By adopting the above technical scheme, the fabric to be dyed is first placed on the frame of the fabric support frame, and the fabric passes back and forth between a plurality of first support rollers and a second support roller, so that the fabric is suspended on the first support rod and the second support rod. Since the first support roller is arranged at the upper end of the second support roller and the number is greater than the second support roller, the two ends of the fabric will be vertically suspended at the two ends of the first support roller, which is convenient for fixing the fabric. Then the staff closes the feed port of the dye box and starts the drive assembly, so that the drive assembly drives the frame to move back and forth in the dye box. After the contact area between the fabric and the dye is increased and it moves back and forth at the bottom of the dye box, the fabric can be soaked more thoroughly, ensuring the dyeing efficiency of the fabric, thereby improving the production efficiency of the fabric.

[0008] The utility model is further configured as follows: inclined surfaces are arranged on all four sides of the frame.

[0009] By adopting the above technical solution, the setting of the inclined surface reduces the resistance of the frame body of the fabric support frame when the frame body moves in the dye box filled with dye, thereby facilitating the movement of the frame body.

[0010] The utility model is further configured as follows: the first supporting roller and the second supporting roller are slidably connected to the first supporting rod and the second supporting rod respectively.

[0011] By adopting the above technical solution, the first support roller and the second support roller can adjust the distance between adjacent first support rollers and the second support rollers on the first support rod and the second support rod.
