[0002] The low-temperature dyeing process is a dyeing method in which the dyeing temperature is lower than the conventional temperature. In the low-temperature dyeing process, dyes suitable for low-temperature environments need to be used, and the dyeing and fixing steps also need to be adjusted according to the characteristics of the selected dyes. This dyeing method may require special equipment and technology to ensure uniform and lasting dyeing effects at lower temperatures. The advantage of the low-temperature dyeing process is that it can dye at lower temperatures, which helps to reduce energy consumption and reduce the impact on the environment. In addition, some dyes may have better dyeing properties at low temperatures, which can produce brighter and longer-lasting colors.
[0003] In the low-temperature dyeing process, the temperature of the dye used is usually lower than the normal temperature, and an open dyeing vat is used for batch dyeing. In the low-temperature dyeing process, due to the low temperature of the dye and the weak activity of the dye, a single use of the dye usually does not make full use of the dye molecules, and it is usually necessary to reflux the dye for secondary use. In order to meet the above needs, the utility model hopes to provide a horizontal stirring tank for low-temperature dyeing of polyester knitted fabrics. Utility Model Content

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] A horizontal stirring cylinder for low-temperature dyeing of polyester knitted fabrics comprises a horizontal stirring cylinder 1, in which a stirring assembly 2 is arranged, and the stirring assembly 2 is used to stir the dye solution in the cylinder to increase the dyeing efficiency. The stirring assembly 2 comprises a rotating roller 3, and two stirring frames 4 are arranged at the rotating roller 3, and two stirring rollers 5 bent outward are arranged between the two stirring frames 4. In order to drive the stirring assembly 2, the device further comprises a driving motor 6, and the driving motor 6 is drivingly connected to the stirring assembly 2.
