1. Best Imitation Cotton Webbing Raw Material Factors First of all, we must pay attention to whether the yarn used in the original material of the webbing is the same batch, because different batches of yarn contain different "oil" conditions, such as blending, it will become a factor of the color in the dyeing process. ; Secondly, whether the original blank has been pre-treated, the refining treatment of the original blank has a very good dyeing effect, because the "oil" on the yarn is removed after the treatment, and the dye can directly contact the fiber for dyeing, without protection .

2. Dyeing tank (or pad car, dye vat, dyeing machine) The pressure of cylinders at both ends of the roller is uniform. The roller of Best Imitation Cotton Webbing continuous hot melt dyeing machine is generally pneumatically pressurized, and there is a cylinder on each side of the roller. When the rolling mill runs for a period of time, due to the action of the moisture in the compressed air, the pressure at both ends of the cylinder will be different, resulting in uneven liquid entrainment rate of the blank strip and color difference in the edge. In addition, the two ends of the roll of the rolling car are pressurized, which produces a certain degree of deflection, resulting in inconsistent rolling margin between the sides, and also causing color difference between the left and the right.
3. The pressure, concentricity, and hardness factors of the dyeing tank rolls are in production. If you want to minimize the impact of the roll pressure on the left, middle and right color difference, then the general roll pressure should be controlled above 0.2MPa during Best Imitation Cotton Webbing dyeing. . In the production process, due to the wear of the rolls, the rolls are required to be calibrated and repaired regularly. Otherwise, it is easy to cause inconsistent rolls due to the misalignment of the rolls and lead to inconsistencies. Rolls with different hardnesses have different lap-over rates. Too hard may cause insufficient dye absorption, and too soft may lead to too much lap-over rate and cause a large amount of dye migration to produce patterns. How much hardness is appropriate? According to Best Imitation Cotton Webbing Decide.
