(Summary description)(1) The same type of dyes should be used when matching colors to facilitate the control of the dyeing process and the simplification of the process.
(2) The dyeing properties of dyes such as directness, dyeing rate, dyeing fastness, etc. should be similar to facilitate the control of shade. Otherwise, the shade will be different after dyeing, and the shade will change due to the different degree 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 shade.
(4) Master the principle of residual color. Residual color means that two colors have the characteristics of subtracting each other. For example, a blue with red light, if you think the red light is too heavy, you can add a small amount of red residual color (green dye) to reduce it. But it should be noted that the residual color principle is used to adjust the color light, only a small amount of adjustment, too much use will affect the color depth and vividness. When matching colors, when the affinity between the dyes and the dyeing rate are too different, the hue of the yarn will be different at different dyeing moments.
