Embodiment 1

[0042] 1) Establish a basic database including the base fabric data of colored fabrics, and the basic color sample data of various dyes dyeing colored fabrics in different concentrations and gradients: Table 1 shows examples of the basic database forms. The basic color sample in the basic database in the step 1) is the apparent depth obtained by dyeing colored fabrics with different concentration gradients of various dyes, namely:

[0043] ①

[0044] In the formula: K represents the absorption coefficient of the tested fabric; S represents the scattering coefficient of the tested fabric; (K / S) m Indicates the apparent color depth of the target colored fabric; (K / S) t Indicates the apparent color depth of colored fabrics; c i "Indicates the dye concentration on the dyed fabric on each dye; k i ˊ represents the concentration of each dye unit on the colored fabric K / S value. Where (K / S) m （ Indicates the apparent color depth of the target colored fabric) and ...

Embodiment 2

[0050] The main steps of this embodiment are the same as in Example 1, the difference is that: the colored plain cotton poplin base fabric is adopted, and the colored plain cotton poplin is dyed by direct red D / BLL, direct navy blue D-R and direct yellow D / 3RNL, and the dyestuff is used for fabric dyeing. The weight percentages are 0.1%, 0.5%, 1%, 1.5%, 2%, 4% respectively, the dosage of sodium sulfate is 15g / L, and the bath ratio is 1:30. Dyeing is started at 30°C, and after 10 minutes of heat preservation, sodium sulfate is added. Raise the temperature to 90°C at 3°C / min, keep it warm for 60 minutes, wash with water, and then fix the color. Fixing formula: 1% color fixing agent, 1% acetic acid, time 15min, temperature 50℃, liquor ratio: 1:30.

[0051] In the same way: the colored plain cotton poplin base fabric and dyed samples are tested by a color matching instrument and then input into the computer to establish a basic database, randomly select 6 target color samples, pre...

Embodiment 3

[0053] The main steps of this embodiment are the same as in Example 1, the difference is that: the colored plain cotton poplin base fabric is adopted, and reactive red 3BS, reactive yellow 3RS and reactive blue M-2GE are used to dye the colored plain cotton poplin, and the weight percentage of the dyestuff to the fabric Respectively 0.1%, 0.5%, 1%, 1.5%, 2%, 4%, the dosage of sodium sulfate is 40g / L, soda ash: 10g / L, liquor ratio 1:30. Dyeing is started at 30°C, and added after 10 minutes of heat preservation For Yuanmingfen, heat up to 60°C at 2°C / min, add half of the soda ash, add the other half of soda ash after 10 minutes of heat preservation and dyeing, wash with water after 40 minutes of heat preservation and dyeing, and then wash with water. Soaping method: soaping agent 2g / L, soda ash 1g / L, soaping at 90°C for 15 minutes, liquor ratio 1:30.

[0054] The colored plain cotton poplin base fabric and the dyed samples are tested by a color matching instrument and input into...

Abstract

The invention discloses a method for predicating an overdying formula of colored fabric. The method comprises the following steps of: 1), establishing a basic database which comprises the base fabric data of the colored fabric and the basic color sample data which is required when the colored fabric is dyed by various dyes in different concentration gradients; 2), determining a corresponding basic database according to a target color; 3), matching the target color by using a computer and making a color sample according to the formula; 4), inputting the obtained color sample into the computer, providing a color correcting formula by the computer, and continuously making the color sample according to the color correcting formula; and 5), repeating the step 4) till the color difference between the color sample and the target color meets the requirement, and stopping making the color sample. By the method, the K(absorption) / S(scattering) value of per unit concentration of various dyes of colored fabric dyeing can be well met, and the color matching speed and the one-time accuracy rate are improved.

Description

[0001] technical field [0002] The invention relates to a method for predicting the overlay formula of colored fabrics. Background technique [0003] With the upgrading of my country's textile industry, in order to improve the production conditions of the domestic printing and dyeing industry and facilitate international trade exchanges, printing and dyeing enterprises have successively introduced color measuring and matching instruments. Compared with manual color matching, computer color matching has the advantages of saving the amount of dyes and chemicals, shortening the production cycle and improving production efficiency. In the actual application process, due to the incomplete understanding of the color matching instrument and color matching theory, the color matching function in the color matching software has not been fully utilized. Contents of the invention [0004] The object of the present invention is to provide a method for predicting the overlay formula o...
