Description

Technical Field

[0001] The present invention relates to the field of textiles, and specifically to a method for auditing textile dyeing formulations. Background Art

[0002] During the processing of textiles in a dyeing factory, they need to go through processes such as pre-setting, pre-treatment before dyeing, dyeing, post-treatment after dyeing, and post-finishing, and finally obtain the finished products; the coloring process of textiles is mainly completed in the dyeing link, but the post-treatment and post-finishing processes also have an important impact on the depth and color tone of the textile color. Therefore, when formulating recipes in the laboratory, some color change spaces need to be reserved to ensure that the color of the final finished product is consistent with the color of the customer sample after going through the subsequent processes.

[0003] Currently, the practice in dyeing factories is that when the color matching master is matching colors and auditing formulations, they reserve color change spaces based on experience. This practice based on experience results in the uncontrollable color of the final finished product sample, increases the color rework rate, and brings certain impacts and losses to the normal production, delivery time, quality, and efficiency of the factory. Summary of the Invention

[0004] The present invention provides a method for auditing textile dyeing formulations to solve the problems raised in the background art.

[0005] The present invention provides the following technical solution: A method for auditing textile dyeing formulations, including the following steps:

[0006] Step 1, collect the color change data of different fabric types and different formulations after different processing links during the production process;

[0007] Step 2, establish a formulation color change model: Through big data analysis, obtain the color change law between the dyed fabric type, formulation color and process, and establish a formulation color change model;

[0008] Step 3, input the sample-making order information and process route: The salesman inputs the information required for the sample-making order, and the technical department formulates the process processing route according to the order requirements;

[0009] Step 4, the laboratory makes samples according to the order requirements;

[0010] Step 5, the color matching master measures the color through a spectrophotometer, compares the dyed sample with the customer sample, and obtains the color difference between the two;

[0011] Step 6. Based on the model established in Step 2 and combined with the pre - established process route, the expert system calculates the impact of each post - dyeing process step on the color, and obtains the color difference value between the final finished product sample and the customer sample. If the color difference value meets the delivery standard, the color - matching master approves the formula. If it does not meet the expectation, repeat the above Steps 4, 5, and 6 until the color difference value meets the delivery standard.

[0012] Step 7. The sample - making worker continues with the subsequent process steps for the dyed sample to obtain a color sample cloth that can be delivered to the customer.

[0013] Step 8. The laboratory pastes the color sample cloth on the color plate card and gives it to the salesperson, who then sends the sample to the customer for confirmation.

[0014] Preferably, in Step 1, it specifically includes the following sub - steps:

[0015] S11. Put the textiles in the production order into the dyeing machine for dyeing, cut the board to obtain the dyed sample. Compare the dyed sample with the customer sample through a spectrophotometer to obtain the color difference values ΔE, ΔL, Δa, and Δb between the two.

[0018] S14. Record each order in production according to the above steps, and accumulate the formula colors of different fabric types and the color change data of subsequent processes.

[0019] Preferably, in Step 2, when the subsequent laboratory color - matching master reviews the sample - making and recipe - replication formulas, the expert system directly calculates based on this model whether the color difference value between the final finished product sample and the customer sample meets the shipping standard to assist the color - matching master in making decisions.

[0020] Preferably, in Step 3, the order requirement information includes the customer, fabric, quality requirements, color fastness requirements, and inspection standard requirements.

[0021] Preferably, in Step 6, the expert system, based on the model established in Step 2 and combined with the pre - established process route, calculates the impact of the post - treatment and post - finishing steps after dyeing on the color.

[0030] Example 1, please refer to Figure 1 and Figure 2 , a method for auditing a textile dyeing formula, Step 1: Collect the color change data of different fabric types and different formulas during the production process after passing through different processing links. Specifically, it includes the following sub-steps:

[0031] (1). Put the textile in the production order into the dyeing machine for dyeing, and cut the board to obtain the sample after dyeing; compare the sample after dyeing with the customer sample through a spectrophotometer to obtain the color difference (ΔE, ΔL, Δa, Δb) between the two.

[0032] (2). Post-treat the textile (such as color fixing, softening, etc.), cut the board to obtain the sample taken out of the vat; compare the sample taken out of the vat with the customer sample through a spectrophotometer to obtain the color difference (ΔE, ΔL, Δa, Δb) between the two.

[0033] (3). Perform post-treatment on textiles (such as raising / sanding, sizing, pre-shrinking, etc.). After each process is completed, cut a sample piece to obtain the process sample after that process. Compare this process sample with the customer sample through a spectrometer to obtain the color difference values (ΔE, ΔL, Δa, Δb) between each process sample and the customer sample.

[0034] (4). Record each production order according to the above steps, and accumulate the formula colors of different fabric types and the color change data for subsequent processes.

[0035] Step 2: Establish a formula color change model: Through big data analysis, obtain the color change rules between the dyed fabric types, formula colors, and processes, and establish a formula color change model. When the subsequent laboratory color matching master reviews the proofing and replication formulas, the expert system directly calculates based on this model whether the color difference between the final product sample and the customer sample meets the shipping standard to assist the color matching master in making decisions.

[0036] Step 3: Enter the proofing order information and process route: The salesperson enters the proofing order requirement information (including customer, fabric, quality requirements, color fastness requirements, inspection standard requirements, etc.), and the technical department formulates the process processing route according to the order requirements.

[0037] Step 4: The laboratory makes a proofing according to the order requirements:

[0038] (1). After the color matching master formulates a formula, hand over the formula to the proofing operator.

[0039] (2). The proofing operator makes a proofing of the textile according to this formula.

[0040] (3). After the proofing is completed, the proofing operator hands over the dyed sample and the formula to the color matching master for review.

[0041] Step 5: The color matching master measures the color of the dyed sample through a spectrometer, compares it with the customer sample, and obtains the color difference values (ΔE, ΔL, Δa, Δb) between the two.

[0042] Step 6: The expert system, based on the model established in Step 2 and combined with the pre-established process processing route, calculates the impact of each process step (post-treatment, post-finishing, etc.) on the color after dyeing, and obtains the color difference between the final product sample and the customer sample. If the color difference meets the delivery standard, the color matching master approves this formula; if it does not meet the expectation, repeat Steps 4, 5, and 6 until the color difference meets the delivery standard.

[0043] Step 7: The proofing operator continues to perform subsequent process steps (post-treatment, post-finishing, etc.) on the dyed sample to obtain a color sample fabric that can be delivered to the customer.

[0044] Step 8: The laboratory pastes the color sample fabric on a color swatch card and hands it over to the salesperson; the salesperson sends the swatch to the customer for confirmation.

[0045] The present invention establishes a color change model among different fabric types, different color formulas and each process; when proofing and reviewing the formula in the laboratory, the color change is reserved in advance through this model to ensure that the color difference between the final product and the customer sample meets the delivery standard after the subsequent processes of processing, thereby reducing the color rework rate.

[0046] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
