The textile to be dyed refers to the textile that is to be dyed. For example, the textile may be a yarn, i.e. the textile to be dyed may be a yarn to be dyed. The dyeing parameter value is a parameter value required to be set for dyeing the textile to be dyed, and can be a bath ratio used for dyeing, for example; the bath ratio is the ratio of the weight of the textile to be dyed to the weight of the dyeing liquor. The number of the standard parameter values is equal to that of the dyeing parameter values, and each dyeing parameter value corresponds to one standard parameter value. After the textile is dyed to a required color, the information corresponding to each dyeing process is stored, so that the terminal generally stores information of historical dyeing production of various textiles dyed to different colors, including formulas used for dyeing different colors. The historical formula is used for historical dyeing production of the textile to be dyed.

The sample formula is obtained by comprehensively processing a plurality of historical formulas. Specifically, a small sample formula can be obtained according to a plurality of historical formulas.
S170: and adjusting the formula of the sample by adopting the adjusting proportion to obtain the dyeing formula of the textile to be dyed.
The formula for dyeing the textile comprises more than two dyes and the corresponding dosage of each dye. And adjusting the sample formula by adopting the adjusting proportion, specifically adjusting the dosage of each dye in the sample formula by adopting the adjusting proportion.
According to the method for obtaining the textile dyeing formula, the dyeing parameter value, the standard parameter value and the plurality of historical formulas of the textile to be dyed are obtained, then the adjustment proportion is obtained according to the dyeing parameter value and the standard parameter value, the hand sample formula is obtained according to the plurality of historical formulas, and finally the hand sample formula is adjusted by adopting the adjustment proportion, so that the dyeing formula of the textile to be dyed is obtained. Therefore, on the basis of obtaining a hand sample formula by processing a historical formula, the hand sample formula is adjusted and optimized by adopting an adjustment proportion obtained according to a dye feeding parameter value and a standard parameter value to obtain a dyeing formula, and the procedures of color mixing and proofing in the traditional technology are not needed; on the one hand, the time consumed for obtaining the dyeing formula can be shortened, so that the dyeing production efficiency is improved, on the other hand, the obtaining of the dyeing formula can be automatically completed, and no additional arrangement of proofing personnel and color matching personnel is needed, so that the manual workload can be reduced. In addition, the condition of color repair caused by abnormal conditions of proofing and color matching in the traditional technology can be avoided on the basis of the historical formula, the dyeing formula has good stability, and the dyeing production passing rate is high.
In one embodiment, the cast dye parameter values include cast bath ratio and cast dye value, and the standard parameter values include standard bath ratio and standard color value. The dye-bath ratio is the bath ratio when the textile to be dyed is dyed; the cast dyeing value is a parameter value for the textile to be dyed which is used to indicate the shade of the color. In this embodiment, the parameter value for indicating the color depth is a brightness value, that is, the cast dyeing value is a cast dyeing brightness value, and the standard color value is a standard brightness value.
Referring to fig. 2, step S110 includes step S111 and step S115.
S111: a batch of textiles to be dyed and a target color are received.
The textiles can comprise different types, and each textile corresponds to a respective batch, which refers to a production batch of the textile; batches of the same textile may also vary. The target color refers to the color to which the textile to be dyed is to be dyed. In particular, the batch and target color of the textile to be dyed may be obtained by receiving manually entered information.
S113: and acquiring the dyeing bath ratio, the dyeing value and the standard color value corresponding to the batch.
The cast dyeing value and the standard color value are stored in advance in correspondence with the lot. Specifically, the terminal stores the dyeing values and standard color values corresponding to each batch of various textiles in advance, and the terminal finds the corresponding dyeing values and standard color values according to the batches. The terminal can receive the manually input dyeing bath ratio of the corresponding batch, or can pre-store the dyeing bath ratio corresponding to each batch of various textiles, and the terminal searches the corresponding dyeing bath ratio according to the batch.
S115: and searching a standard bath ratio corresponding to the target color and a historical formula for multiple times of historical dyeing production.
The terminal can pre-store the standard bath ratios corresponding to all colors and historical formulas of historical dyeing production for dyeing various textiles into different colors; and after receiving the target color, searching a corresponding standard bath ratio and a plurality of historical formulas according to the target color.
The cast dyeing value and the standard color value are related to the type of the textile to be dyed; the colors to be dyed are different and the corresponding formulas are different, so that the historical formulas of the textiles to be dyed are related to the target colors to be dyed. Through the steps S111 to S115, the information related to each color is obtained according to the batch and the target color, and the accuracy is high.
It is understood that in other embodiments, step S110 may be: the method comprises the steps of receiving input dyeing parameters, standard parameters and a plurality of historical formulas of textiles to be dyed. That is, the values of the dye delivery parameters, the standard parameters and the plurality of historical recipes for the textile to be dyed may be directly manually entered by the user.
In an embodiment, before step S115, step (a1) and step (a2) are further included.
Step (a 1): and searching the bath ratios of multiple times of historical dyeing production corresponding to each color to respectively obtain multiple historical bath ratios of each color.
Wherein the historical bath ratio is the bath ratio used in the historical dyeing production. Each color can correspond to a plurality of historical dyeing production, each historical dyeing production corresponds to one bath ratio, and therefore one color corresponds to a plurality of historical bath ratios.
Step (a 2): selecting and storing the historical bath ratio with the largest quantity ratio from the plurality of historical bath ratios of the various colors to obtain the standard bath ratio corresponding to the various colors.
Among a plurality of historical bath ratios corresponding to one color, there may be a historical bath ratio of the same value. The historical bath ratio with the largest number ratio is the historical bath ratio corresponding to the numerical value with the largest frequency of appearance in a plurality of historical bath ratios corresponding to the same color. For example, blue corresponds to historical bath ratios of 1:8, 1:5, 1:8, and 1: 10; the number ratio of 1:8 was 1/2, and the number ratios of 1:5 and 1:10 were 1/4, the number ratio of 1:8 was the largest, and 1:8 was taken as the standard bath ratio for blue.
By selecting the historical bath ratio with the largest quantity ratio as the standard bath ratio in the steps (a1) and (a2), the accuracy of the standard bath ratio can be improved, and the accuracy of the adjustment ratio obtained based on the standard bath ratio can be improved. Specifically, step (a1) may be performed after step S111, or may be performed before step S111.
Correspondingly, step S115 is to search a formula of multiple historical dyeing productions corresponding to the target color to obtain multiple historical formulas corresponding to the target color; and searching the standard bath ratio corresponding to the target color from the standard bath ratios corresponding to the colors.
In one embodiment, the cast dye parameter values include cast bath ratio and cast dye value, and the standard parameter values include standard bath ratio and standard color value. Specifically, the adjustment ratio includes a first ratio and a second ratio. With continued reference to fig. 2, S130 includes step S131 and step S133.
S131: the first ratio is calculated from the cast dyeing value and the standard color value.
S133: and calculating according to the dyeing bath ratio and the standard bath ratio to obtain a second ratio.
The first proportion is obtained according to the dyeing value and the standard color value, the second proportion is obtained according to the dyeing bath ratio and the standard bath ratio, the hand sample formula is adjusted according to the first proportion and the second proportion, the influence of the bath ratio and the parameter value expressing the color depth on dyeing is comprehensively considered, and the accuracy of adjusting the hand sample formula can be improved.
In one embodiment, step S131 includes: calculating the difference value of the dyeing value and the standard color value to obtain a color value difference value; and obtaining a first proportion according to the color value difference value and a first preset coefficient, wherein the first proportion is increased along with the increase of the color value difference value.
The color value difference may be a positive value or a negative value. Specifically, the step of calculating the difference between the cast dyeing value and the standard color value to obtain the color value difference in step S131 includes: and calculating the difference value of the color value obtained by subtracting the standard color value from the dyeing value. Correspondingly, if the color value difference is positive, the dyeing value is greater than the standard color value, and the trend of correspondingly adjusting the first proportion is shown as deepening the dye concentration in the formula; if the color value difference is negative, the cast dyeing value is smaller than the standard color value, and the trend of the corresponding adjustment of the first proportion is shown to be that the dye concentration in the formula is reduced.
It is understood that in other embodiments, the color value difference may be calculated by subtracting the value of the cast color value from the standard color value; correspondingly, if the color value difference is positive, the trend of the first proportional corresponding adjustment is to reduce the dye concentration in the formula, and if the color value difference is negative, the trend of the first proportional corresponding adjustment is to increase the dye concentration in the formula.
Specifically, after calculating the difference between the standard color value and the cast dyeing value in step S131 to obtain the color value difference, the method further includes: judging whether the color value difference is smaller than a preset value, if so, taking 0 as a first proportion; if not, the step of obtaining the first proportion according to the color value difference value and the first preset coefficient is executed. The color value difference value is compared with a preset value, if the color value difference value is smaller than the preset value, the standard color value and the dyeing value are basically the same, at the moment, the first proportion is set to be 0, namely, the formula of the hand sample does not need to be adjusted according to the first proportion, and the calculation program can be simplified. In this embodiment, the preset value is 0.01.
The first preset coefficient is obtained through careful research and analysis, the first proportion is obtained through the first preset coefficient and the color value difference value, and accuracy is high. In this example, the first ratio is 20%/5.

wherein, Δ L is a color value difference, TD1 is a first proportion, and 20%/5 is a first preset coefficient.
In one embodiment, step S133 includes: calculating the difference value of the dye liquor ratio corresponding to the dyeing bath ratio and the dye liquor ratio corresponding to the standard bath ratio to obtain a bath ratio difference value; and obtaining a second proportion according to the bath ratio difference and a second preset coefficient, wherein the second proportion is increased along with the increase of the bath ratio difference.
The bath ratio is the ratio of the weight of the textile to be dyed to the weight of the dye liquor, and one bath ratio is composed of the ratio corresponding to the weight of the textile to be dyed and the ratio corresponding to the weight of the dye liquor; the dye liquor ratio is the ratio corresponding to the weight of the dye liquor. For example, if the dye bath ratio/standard bath ratio is 1:10, the number of dye liquor ratios corresponding to the dye bath ratio/standard bath ratio is 10.
The bath ratio difference may be a positive value or a negative value. Specifically, the step of calculating the difference between the dye liquor ratio corresponding to the dye liquor ratio and the dye liquor ratio corresponding to the standard bath ratio to obtain the bath ratio difference in step S133 includes: and calculating the value obtained by subtracting the specific gravity of the dye liquor corresponding to the standard bath ratio from the specific gravity of the dye liquor corresponding to the dyeing bath ratio to obtain a bath ratio difference value. Correspondingly, if the bath ratio difference is positive, the trend of correspondingly adjusting the second ratio is shown to deepen the concentration of the dye in the formula; if the bath ratio difference is negative, the corresponding adjustment trend of the second ratio is shown to be that the dye concentration in the formula is reduced.
It is understood that in other embodiments, the bath ratio difference value may also be obtained by subtracting the value of the specific gravity of the dye liquor corresponding to the dyeing bath ratio from the specific gravity of the dye liquor corresponding to the standard bath ratio; correspondingly, if the bath ratio difference is positive, the trend of the corresponding adjustment of the second ratio is shown as reducing the concentration of the dye in the formula, and if the bath ratio difference is negative, the trend of the corresponding adjustment of the second ratio is shown as increasing the concentration of the dye in the formula. Specifically, the condition that the corresponding adjustment trend of the plus and minus signs of the color value difference value is the same as the corresponding adjustment trend of the plus and minus signs of the bath ratio difference value is met; that is, if the color value difference is a value obtained by subtracting the standard color value from the calculated dyeing value, the bath ratio difference is a value obtained by subtracting the specific gravity of the dye liquor corresponding to the standard bath ratio from the specific gravity of the dye liquor corresponding to the calculated dyeing bath ratio.
Specifically, after the step S133 calculates the difference between the dye liquor ratio number corresponding to the dye liquor ratio and the dye liquor ratio number corresponding to the standard bath ratio to obtain the bath ratio difference, the method further includes: judging whether the bath ratio difference is smaller than a preset value, if so, taking 0 as a second ratio; if not, the step of obtaining a second proportion according to the bath ratio difference value and a second preset coefficient is executed. The bath ratio difference value is compared with the preset value, if the bath ratio difference value is smaller than the preset value, the dye bath feeding ratio is basically the same as the standard bath ratio, at the moment, the second ratio is set to be 0, namely, the hand sample formula does not need to be adjusted according to the second ratio, and the calculation program can be simplified. In this embodiment, the preset value is 0.01.
The second preset coefficient is obtained through careful research and analysis, the second ratio is obtained through the second preset coefficient and the bath ratio difference value, and accuracy is high. In this example, the second ratio is 1.5%/2.
Specifically, the step of obtaining the second ratio according to the bath ratio difference and the second preset coefficient in step S133 includes: and calculating the product of the bath ratio difference and a second preset coefficient to obtain a second proportion. Step S133 obtains the second ratio by calculation using the following formula (2):
TD2 ═ Δ Y (1.5%/2) formula (2);
wherein, the delta Y is the bath ratio difference value, the TD2 is the second proportion, and 1.5%/2 is the second preset coefficient.
In one embodiment, with continued reference to FIG. 2, the historical recipe includes raw weight parameter values for more than two dyes. The weight parameter value is a parameter value used to indicate the amount of dye used in the formulation and may be, for example, the weight of dye as a percentage of the weight of the textile to be dyed.
