Embodiment 1
[0056] A design method of a dye formula, which is the same as the above-mentioned steps, specifically: the candidate dye formula and the historical dye formula are all composed of reactive red 239 and reactive yellow 176. When training the BP neural network model, the concentration of the dye solution is 5g / L, The pH value is 7, the dyeing temperature is 60°C, the bath ratio is 1:10, the amount of neutral salt is 60g / L, the process is exhaust dyeing, the fabric is cotton fabric, the laser wavelength range of the Raman spectrometer is 785nm, and the laser power is 20mW , the exposure time is 0.2sec, the chemometric method is the partial least square method, reactive red 239 and reactive yellow 176 are input into the BP neural network model after training at the same time with different mass percentages, and the preparation ratio of the dye in the candidate dye formula (mass ratio ), K of each dye 0 value and the corresponding D max Value is as shown in table 1, obtains reactiv...
Embodiment 2
[0060] A method for designing a dye formula is basically the same as in Example 1, except that the candidate dye formula and the historical dye formula are all composed of reactive red 239 and reactive blue 194, and reactive red 239 and reactive blue 194 are in different mass percentages Simultaneously input the trained BP neural network model, the preparation ratio (mass ratio) of dyes in the candidate dye formula, the K of each dye 0 value and the corresponding D max Value is as shown in table 2, obtains reactive red 239: the D of the dye formula when reactive blue 194 is 7:3 max If the value is the smallest, the compatibility of the dye formula is the best, and this formula is the final designed formula.

Embodiment 3
[0064] A method for designing a dye formula is basically the same as in Example 1, except that the candidate dye formula and the historical dye formula are all composed of reactive red 239, reactive yellow 176 and reactive blue 194, reactive red 239, reactive yellow 176 and Reactive blue 194 is input into the trained BP neural network model with different mass percentages, the preparation ratio (mass ratio) of dyes in the candidate dye formula, the K of each dye 0 value and the corresponding D max Value is as shown in table 3, obtains reactive red 239: reactive yellow 176: the D of the dye formula when reactive blue 194 is 4:4:2 max If the value is the smallest, the compatibility of the dye formula is the best, and this formula is the final designed formula.
