Color matching of disperse dyes

1. Principles:

① The three primary colors (yellow, red, blue) of color matching have the same and similar characteristics

For example: use low-temperature three primary colors or medium-temperature three primary colors or high-temperature three primary colors, and more importantly, if you dye high-wash fabrics, you must choose a complete set of high-wash dyes, such as PUD series, HXF series, and HWF series on the market. But we must remember to combine conventional dyes and high-wash dyes for shade or cost. If ordinary S-5BL red jade is added to the high-wash PUD black, then after n times of washing, the fabric will become more and more blue-yellow, because the red is washed away. The same principle applies to high-sun dyes, some deep black fabrics turn yellow and blue after being exposed to the sun, and the red light fastness is poor, and so on. Therefore, we must be strict when choosing high-demand dyes.

②The lowest dye cost on the basis of meeting customer requirements

③The number of selected materials should be as small as possible, and 4 kinds of dyes should not be used as much as possible

④Easy for workshop color matching

⑤Easy to stabilize workshop quality

2. Laboratory sample test:

First make a small sample in the laboratory to determine the stability of the dye compatibility. Change the concentration of the prescription, dyeing temperature, dyeing time, and pH value of the dye solution to compare whether the compatibility of the dye combination is consistent.

For example, to make an extremely sensitive dark brown color, use (red-167#, orange-30#, blue-79# combined). Brown is a particularly sensitive color. If the material selection and compatibility are disordered, it will easily lead to unstable color light or a high probability of color bloom. If: Change Lan-79# to Lan-165# or Lan-183# to spell it out, it can also be spelled out, but it must be considered that a sensitive color with a deep ternary as the main ingredient is combined with a medium ternary dye. There will be a big difference in shade or level dyeing stability. Therefore, the material selection and compatibility of a color are very important.

3. Material selection:

① Use light ternary (E type) for light color (there are two more mature sets on the market: AC-E yellow red blue series, and E-12GFL yellow, 3B red or FB red, 2BLN blue)

② Medium ternary (SE type) for medium color (such as yellow-211#, blue-183#, red-73#)

③Deep ternary (S type or H type) for dark colors (orange-30#, red-167#, blue-79￥, etc.)

④ In principle, E-type should not be combined with S-type

⑤Try not to use secondary colors (such as orange, gray, green, purple) for color matching
