The low bath ratio dyeing machine is the ratio between the volume of dyeing solution and the fabric weight when dyeing. The bath ratio of large and small samples can be the same or different. The key is to adjust the prescription.

Each dye factory is right dyeing machine dyeing formula is taken seriously quite, but often it is to encounter chromatic aberration to think of adjusting formula first, actually bath is bigger also than influence. At the end of dyeing, most dyes reach a balance of concentration in water and fiber. If the bath ratio is too large, the amount of water, especially with reactive dyes, direct dyes and other dyeing, although the residual concentration in the dyeing bath change little, but the amount of dye left in the water is more, resulting in less dye on the fabric, the color gap is large. Therefore, the control of bath ratio is also very important in the production of continuous cylinder or single production.

Due to the difference in the actual inner diameter of each dyeing VAT of the same model, the factory should measure the actual bath volume of each dyeing machine, and indicate the actual liquid volume in the cylinder on the liquid level scale. When dyeing, the amount of water required is calculated according to the quality of the fabric and the bath ratio. Now there is a computer control device for liquid level, which can connect the water amount of each dyeing machine with the computer centralized control system. The computer centralized control manager in the dyeing workshop can control the bath ratio of each VAT of fabric according to the quality, so as to reduce the influence of bath ratio on color difference.
