          Color matching of HTHP cone yarn dyeing machine and its attention
          Jun 18, 2019

          The HTHP cone yarn dyeing machine can effectively select the dye of the approximate color as the main color during the working process, and then add a small amount of other dyes to adjust the color light. This method can obtain better reproducibility and leveling effect, but requires Dye chromatography is complete. Another method is to use "three primary colors" color matching, such as reactive dyes, disperse dyes, cationic dyes and the like.

           

          Color matching of high temperature and high pressure yarn dyeing machine and its attention

           

          In printing and dyeing, the process of mixing two or more dyes is called color matching or color matching. When dyeing color matching, generally pay attention to the following points:

           

          (1) The same type of dye should be used for color matching to facilitate the control of the dyeing process and the simplification of the process.

           

          (2) Dyeing properties of dyes such as directness, dyeing rate, and color fastness should be similar to facilitate color light control. Otherwise, the color will be different after dyeing, and the color light will change due to the different degrees of fading during post-processing or use.

           

          (3) The number of dyes for color matching should be as small as possible to facilitate the control of color light.

           

          (4) Master the principle of residual color. The remaining color means that the two colors have mutual elimination characteristics.

           

          The high temperature and high pressure yarn dyeing machine is only a small amount of adjustment, too much amount will affect the color depth and vividness. When color matching, when the affinity between the dyes and the dyeing rate are too different, the hue of the yarns will be different at different dyeing times. In extreme cases, high-affinity, low dye-dyeing dyes will replace the dyed dyes with low affinity and high dye uptake rates.
