Description
本發明是有關於一種染色製程的驗證方法。 The invention relates to a verification method for a dyeing process.
隨著生活水準的提高,消費者對織物的功能亦有了新的要求,因此織物的需求也與日俱增。於織物的大量生產過程中,作為織物原料的布材會先經過清洗與烘乾製程,接著才會開始進行與染色相關的程序。 With the improvement of living standards, consumers have new requirements for the function of fabrics, so the demand for fabrics is also increasing. During the mass production of fabrics, the fabrics used as fabric raw materials are first subjected to a washing and drying process, and then the procedures related to dyeing are started.
於染色製程中,由於染色製程需要一定的時間才可完成,故會牽涉到染色結果的因素也有一定的複雜程度。也因為這樣,染色製程的各條件設定會需要使用經驗法則加入判斷。然而,由於經驗法則並非屬於客觀的判斷依據,故染色製程在其各條件設定上仍會發生染色結果與預期顏色有所差異的狀況。因此,如何能對染色製程做調控以及驗證已成為相關領域的焦點。 In the dyeing process, since the dyeing process takes a certain amount of time to complete, the factors involved in the dyeing result also have a certain degree of complexity. Because of this, the setting of each condition of the dyeing process requires the use of rules of thumb to add judgment. However, because the rule of thumb is not an objective basis for judgment, the dyeing process may still differ from the expected color in the setting of various conditions. Therefore, how to regulate and verify the dyeing process has become the focus of related fields.

For the sake of clarity, many practical details will be described in the following description. It should be understood, however, that these practical details should not be used to limit the invention. That is, in some embodiments of the present invention, these practical details are unnecessary.

本揭露內容提供一種染色製程的驗證方法,其可在不同染程進行期間,對布料或染液進行數據擷取,並將所擷取的數據建立成為資料庫。在已建立資料庫的情況下,當進行了新的染程之後,可使用資料庫判讀此染程的結果是否合格。再者,若染程未被判讀為合格,則驗證方法也包含對染程提供建議,從而修正下一次的染程參數。 This disclosure provides a method for verifying the dyeing process, which can perform data acquisition on the cloth or dyeing liquid during the different dyeing processes, and build the acquired data into a database. In the case of a database, when a new dyeing process is performed, the database can be used to determine whether the results of the dyeing process are acceptable. Furthermore, if the dyeing process is not judged as a pass, the verification method also includes providing suggestions for the dyeing process so as to correct the next dyeing process parameters.
請先看到第1圖,第1圖繪示本揭露內容的部分實施方式的染色製程的驗證方法的流程圖。染色製程的驗證方法包含步驟S10、步驟S20、步驟S30、步驟S40、步驟S50以及步驟S60,其中步驟S10為資料前處理,步驟S20為產生回歸方 程式,步驟S30為對布料進行染色,步驟S40為進行驗證,步驟S50為提供建議,步驟S60為匯入至資料庫。 Please see FIG. 1 first, which illustrates a flowchart of a verification method of a dyeing process according to some embodiments of the present disclosure. The verification method of the dyeing process includes steps S10, S20, S30, S40, S50, and S60, where step S10 is pre-processing of the data and step S20 is to generate a regression method. Program, step S30 is to dye the cloth, step S40 is to verify, step S50 is to provide suggestions, and step S60 is to import to the database.
於步驟S10中,資料前處理包含建立資料庫。舉例來說,可透過在多次染程中進行數據擷取,並利用所擷取的數據來建立資料庫。更進一步來說,可在單次染程進行期間,收集此單次染程的相關數據,其中相關數據的來源可以是對布料或染液進行取樣,並將取樣結果整合為一筆數據。也就是說,當進行了一次染程之後,即可自此次染程擷取到一筆數據。而當進行了多次染程之後,即可藉由所擷取到的多筆數據建立資料庫。在此,所述的「多次染程」,可以是「多次相同的染程」、「多次不同的染程」或是「一部分相同而另一部分不相同的染程」。此外,所述的「資料庫」可以是由至少6000筆數據來建立,且用來收集相關數據的布料的材料可以是聚酯纖維(PET)或尼龍(NYLON)。 In step S10, the data pre-processing includes establishing a database. For example, data acquisition can be performed in multiple dyeing passes, and the acquired data can be used to build a database. Furthermore, during a single dyeing process, relevant data of the single dyeing process can be collected. The source of the relevant data can be the sampling of the cloth or the dyeing solution, and the sampling results are integrated into a single piece of data. In other words, after a dyeing process, a piece of data can be obtained from the dyeing process. After multiple dyeing passes, a database can be created from the acquired data. Here, the "multiple dyeing passes" may be "multiple same dyeing passes", "multiple different dyeing passes", or "a part of the same dyeing process and another part of the dyeing process being different". In addition, the "database" may be established by at least 6000 pieces of data, and the material of the cloth used to collect the relevant data may be polyester fiber (PET) or nylon (NYLON).
上述的「對布料或染液進行取樣」可以是由超過一種的量測元件來達成,且進行取樣的時間點可依據製程溫度設定曲線來定義。舉例來說,進行步驟S10之前,可先由專家系統對預定染程製作出時間與上色率之間的關係曲線圖,其中此關係曲線圖可稱為製程溫度設定曲線。接著,進行取樣的時間點可依據製程溫度設定曲線來定義。以進行單次染程為例,可先將製程溫度設定曲線在上色率分別為20%、50%以及90%所對應的時間點標記為第一時間點、第二時間點以及第三時間點,並且在第一時間點、第二時間點以及第三時間點分別進行第一次取樣、第二次取樣以及第三次取樣。 The above-mentioned "sampling of cloth or dyeing liquid" can be achieved by more than one measuring element, and the time point of sampling can be defined according to the process temperature setting curve. For example, before step S10, an expert system may first prepare a relationship curve between time and coloring rate for a predetermined dyeing process, and the relationship curve may be referred to as a process temperature setting curve. Then, the time point for sampling can be defined according to the process temperature setting curve. Taking a single dyeing process as an example, the time points of the process temperature setting curve at the coloring rates of 20%, 50%, and 90%, respectively, can be marked as the first time point, the second time point, and the third time. Point, and perform the first sampling, the second sampling, and the third sampling at the first time point, the second time point, and the third time point, respectively.
在每一次的取樣過程中,可由不同的量測元件分別進行取樣,舉例來說,請看到第2圖,第2圖繪示對單次染程進行數據擷取的流程圖。如第2圖所示,第1圖的步驟S10的資料前處理包含步驟S102、步驟S104、步驟S106、步驟S108、步驟S110以及步驟S112,其中步驟S102為擷取影像,步驟S104為分析Lab值,步驟S106為分析染料,步驟S108為傳送至電子計算機,步驟S110為產生分光曲線分布圖,步驟S112為自分光曲線得到數據,各步驟的具體內容將分述如下。 In each sampling process, different measurement elements can be used for sampling. For example, see Figure 2. Figure 2 shows a flowchart of data acquisition for a single dyeing pass. As shown in FIG. 2, the data pre-processing of step S10 in FIG. 1 includes steps S102, S104, S106, S108, S110, and S112, where step S102 is to capture an image and step S104 is to analyze the Lab value Step S106 is analyzing the dye, step S108 is transmitting to the electronic computer, step S110 is generating a spectroscopic curve distribution map, and step S112 is obtaining data from the spectroscopic curve. The specific content of each step will be described below.
在步驟S102中,擷取影像可透過感光元件(Charge-coupled Device;CCD)達成,像是使用CCD工業相機。CCD工業相機的量測目標可以是染程中的布料,並在對應的取樣時間點擷取目標布料的影像。例如,可透過CCD工業相機在前所述的第一時間點、第二時間點以及第三時間點分別對目標布料進行第一次影像擷取、第二次影像擷取以及第三次影像擷取。因此,於步驟S102完成後,可得到目標布料在不同時間點的影像。 In step S102, capturing an image can be achieved through a photosensitive-coupled device (CCD), such as using a CCD industrial camera. The measurement target of the CCD industrial camera can be the cloth in the dyeing process, and capture the image of the target cloth at the corresponding sampling time point. For example, a CCD industrial camera can be used to perform the first image capture, the second image capture, and the third image capture of the target cloth at the first time point, the second time point, and the third time point described above. take. Therefore, after step S102 is completed, images of the target cloth at different time points can be obtained.
在步驟S104中,分析Lab值可透過分光測色儀(DataColor)達成。分光測色儀的量測目標可以是染程中的布料,並在對應的取樣時間點分析目標布料的Lab值。例如,可透過分光測色儀在前所述的第一時間點、第二時間點以及第三時間點分別對目標布料進行第一次分析、第二次分析以及第三次分析。因此,於步驟S104完成後,可得到目標布料在不同時間點的Lab值。 In step S104, the analysis Lab value can be achieved through a spectrophotometer (DataColor). The measurement target of the spectrophotometer can be the cloth in the dyeing process, and the Lab value of the target cloth is analyzed at the corresponding sampling time point. For example, the first analysis, the second analysis, and the third analysis can be performed on the target cloth through the spectrophotometer at the first time point, the second time point, and the third time point described above. Therefore, after step S104 is completed, Lab values of the target cloth at different time points can be obtained.
在步驟S106中,分析染料可透過連續式上色監控 設備(optilab)達成。分光測色儀的量測目標可以是染程中的染液,即量測目標可以是染程進行期間經使用過的染液(或可稱殘液)。具體來說,可在對應的時間點,將染程使用中的染液取出作分析。例如,可在前所述的第一時間點、第二時間點以及第三時間點分別將染程使用中的染液取出作第一次分析、第二次分析以及第三次分析,並結合此三次分析結果取得初始分光曲線分布圖。因此,於步驟S106完成後,可得到染液的初始分光曲線分布圖。 In step S106, the analysis dye can be monitored through continuous coloring Device (optilab) reached. The measurement target of the spectrophotometer can be a dye solution in the dyeing process, that is, the measurement target can be a dye solution (or a residual solution) used during the dyeing process. Specifically, the dye solution used in the dyeing process can be taken out for analysis at the corresponding time point. For example, the dye solution in use during the dyeing process can be taken out for the first analysis, the second analysis, and the third analysis at the first time point, the second time point, and the third time point described above, and combined. The three analysis results obtained the initial spectral curve distribution. Therefore, after step S106 is completed, an initial spectroscopic curve distribution diagram of the dye solution can be obtained.
在步驟S108中,可將前述所得到的取樣結果傳送至電子計算機,以將各取樣結果整合。步驟S102所得到的目標布料在不同時間點的影像可傳送至電子計算機,接著再透過電子計算機自這些影像得到影像中的每一個像素的像素值(例如RGB值)。步驟S104所得到的目標布料在不同時間點的Lab值可傳送至電子計算機,並在與上述像素值結合後獲得布料的光譜資料,其中光譜資料記錄了布料在各波長所對應的光強度。 In step S108, the sampling results obtained above may be transmitted to an electronic computer to integrate the sampling results. The images of the target cloth at different time points obtained in step S102 can be transmitted to an electronic computer, and then the pixel value (for example, RGB value) of each pixel in the image is obtained from the images through the electronic computer. The Lab values of the target cloth obtained at step S104 at different time points can be transmitted to an electronic computer, and the spectrum data of the cloth is obtained after combining with the pixel values, wherein the spectrum data records the light intensity corresponding to the cloth at each wavelength.
在步驟S110中,可透過電子計算機結合光譜資料及初始分光曲線分布圖,藉以得到分光曲線分布圖,如第3圖所示,其中第3圖繪示在步驟S110得到的分光曲線分布圖。分光曲線分布圖的橫軸為時間,其單位為小時:分鐘,而分光曲線分布圖的橫軸標示了兩個參數,其一為溫度,單位為℃,另一為上色率,單位為%。 In step S110, an electronic computer can be combined with the spectral data and the initial spectral curve distribution chart to obtain a spectral curve distribution chart, as shown in FIG. 3, where the third chart illustrates the spectral curve distribution chart obtained in step S110. The horizontal axis of the spectroscopic curve distribution is time, and its unit is hour: minutes, and the horizontal axis of the spectroscopic curve distribution chart indicates two parameters, one is temperature, the unit is ℃, and the other is the coloring rate, the unit is%. .
第3圖中,分光曲線分布圖顯示了製程溫度設定曲線CN以及各色光的分光曲線,其中各色光的分光曲線包含 藍色分光曲線C1、綠色分光曲線C2、紅色分光曲線C3以及黃色分光曲線C4。根據製程溫度設定曲線CN,可判讀出染程進行時間與其預計溫度以及預計上色率的關係,而根據各色光的分光曲線,可判讀出染程進行時間與其溫度以及上色率的關係。 In Figure 3, the distribution curve of the spectroscopic curve shows the process temperature setting curve CN and the spectroscopic curve of each color light, where the spectroscopic curve of each color light includes The blue spectral curve C1, the green spectral curve C2, the red spectral curve C3, and the yellow spectral curve C4. According to the process temperature setting curve CN, the relationship between the reading process time and its estimated temperature and coloring rate can be judged. According to the spectral curve of each color light, the relationship between the reading process time and its temperature and coloring rate can be judged.
於得到分光曲線分布圖之後,可進入步驟S112。在步驟S112中,可藉由步驟S110所得到的分光曲線分布圖判讀出各色光在不同上色率的溫度差,並於判讀後,將各色光在不同上色率的最大溫度差記錄下來,從而獲得用來建立資料庫的數據。所記錄的最大溫度差可以是各色光在上色率20%的最大溫度差、各色光在上色率50%的最大溫度差以及各色光在上色率90%的最大溫度差。 After obtaining the spectral curve distribution chart, the process may proceed to step S112. In step S112, the temperature difference of each color light at different coloring rates can be read out by using the spectral curve distribution chart obtained in step S110, and after reading, the maximum temperature difference of each color light at different coloring rates is recorded. In order to obtain the data used to build the database. The maximum temperature difference recorded may be a maximum temperature difference of each color light at a coloring rate of 20%, a maximum temperature difference of each color light at a coloring rate of 50%, and a maximum temperature difference of each color light at a coloring rate of 90%.
以記錄各色光在上色率20%的最大溫度差為例,請看到第3圖,當要比較各色光在上色率20%的溫度的時候,可先看到縱軸的上色率20%處,並自此處對到藍色分光曲線C1、綠色分光曲線C2、紅色分光曲線C3以及黃色分光曲線C4,接著再選取對應到的距離最遠的兩點,像是藍色分光曲線C1上的點P1以及黃色分光曲線C4上的點P2。 Take the maximum temperature difference of each color light at the coloring rate of 20% as an example. Please see Figure 3. When comparing the temperature of each color light at the coloring rate of 20%, you can first see the coloring rate of the vertical axis. At 20%, the blue spectral curve C1, the green spectral curve C2, the red spectral curve C3, and the yellow spectral curve C4 are aligned from here, and then the two points corresponding to the farthest distance are selected, such as the blue spectral curve Point P1 on C1 and point P2 on the yellow spectral curve C4.
於對到點P1以及點P2後,再分別自點P1以及點P2對到製程溫度設定曲線CN,並選取對應到製程溫度設定曲線CN上的兩點,像是點P1會對應到製程溫度設定曲線CN上的的點P3,而點P2會對應到製程溫度設定曲線CN上的的點P4。接著,再分別自點P3以及點P4對到縱軸的溫度,其中點P3以及點P4所對應到的溫度的差值即為各色光在上色率20%的最 大溫度差。 After reaching point P1 and point P2, then from point P1 and point P2 to the process temperature setting curve CN, and select two points corresponding to the process temperature setting curve CN. For example, point P1 will correspond to the process temperature setting. Point P3 on curve CN, and point P2 will correspond to point P4 on the process temperature setting curve CN. Next, the temperature from the point P3 and the point P4 to the vertical axis respectively, and the difference between the temperatures corresponding to the points P3 and P4 is the maximum value of the coloring rate of 20% for each color light. Large temperature difference.
在得到各色光在上色率20%的最大溫度差後,可再繼續依相同規則得到各色光在上色率50%的最大溫度差以及各色光在上色率90%的最大溫度差,在此不再贅述。對於單次染程而言,當得到各色光在上色率20%的最大溫度差、各色光在上色率50%的最大溫度差以及各色光在上色率90%的最大溫度差之後,即完成了數據擷取,並從中記錄了一筆數據,其中此一筆數據包含了以上三個數值。 After obtaining the maximum temperature difference of each color light at the coloring rate of 20%, the maximum temperature difference of each color light at the coloring rate of 50% and the maximum temperature difference of each color light at the coloring rate of 90% can be continued according to the same rules. This will not be repeated here. For a single dyeing pass, after obtaining the maximum temperature difference of each color light at the coloring rate of 20%, the maximum temperature difference of each color light at the coloring rate of 50%, and the maximum temperature difference of each color light at the coloring rate of 90%, it is completed. Data extraction, and recorded a piece of data from it, this piece of data contains the above three values.
請再回到第1圖。步驟S10的資料前處理包含在不同染程進行期間,進行如上所述的數據擷取。同前所述,當進行了多次染程之後,即可藉由擷取到的多筆數據建立資料庫。 Please go back to Figure 1. The data pre-processing of step S10 includes performing data acquisition as described above during different dyeing processes. As mentioned earlier, after multiple dyeing passes, a database can be created from the multiple data captured.
當資料庫建立完成後,可進入步驟S20。步驟S20中,可利用資料庫內的數據建立第一回歸直線方程式,其中第一回歸直線方程式的形式可以是Y=AX1+BX2+CX3+D,其中變數Y可視作為染色結果,例如像是色差值△E,變數X1、X2以及X3分別可以是各色光在上色率20%、50%及90%的最大溫度差,數值A、B、C為係數,而數值D為常數。此外,建立第一回歸直線方程式的演算法可以是透過線性回歸、神經網路或支持向量機。 After the database is established, the process may proceed to step S20. In step S20, the first regression line equation can be established by using the data in the database. The form of the first regression line equation can be Y = AX 1 + BX 2 + CX 3 + D, and the variable Y can be regarded as the coloring result. For example, Like the color difference value △ E, the variables X 1 , X 2 and X 3 can be the maximum temperature difference of the coloring rate of each color 20%, 50% and 90%, the values A, B, and C are coefficients, and the values are D is constant. In addition, the algorithm for establishing the first regression linear equation may be through linear regression, neural network, or support vector machine.
當第一回歸直線方程式建立完成後,可進入步驟S30以及步驟S40,並使用第一回歸直線方程式做為驗證工具,從而對後續所進行的染程進行驗證。 After the establishment of the first regression linear equation is completed, it may proceed to step S30 and step S40, and use the first regression linear equation as a verification tool to verify the subsequent dyeing process.
在步驟S30中,可開始進行染程,以對測試布料進行染色。於測試布料的染程進行期間,也進行如第2圖所述 的數據擷取,藉以獲得測試布料的測試數據。具體來說,在對測試布料進行如第2圖所述的數據擷取後,即可獲得測試布料的分光曲線分布圖。也因此,在對測試布料進行如第2圖所述的數據擷取後,也可獲得測試布料的各色光在上色率20%的最大溫度差、各色光在上色率50%的最大溫度差以及各色光在上色率90%的最大溫度差。 In step S30, a dyeing process may be started to dye the test cloth. During the dyeing process of the test cloth, it is also performed as shown in Figure 2. Data capture to obtain test data for test cloth. Specifically, after performing data acquisition as described in FIG. 2 on the test cloth, a spectroscopic curve distribution chart of the test cloth can be obtained. Therefore, after the data acquisition of the test cloth as shown in FIG. 2 is performed, the maximum temperature difference of the coloring rate of each color of the test cloth is 20%, and the maximum temperature of the coloring rate of each color of the test cloth is 50%. Difference and the maximum temperature difference of each color light at 90%.
在染程完成後,則進入步驟S40。在步驟S40中,可透過將測試布料的測試數據代入至第一回歸直線方程式來驗證測試布料的染色結果是否合格。具體來說,可將於步驟S30中得到的各色光在上色率20%、50%及90%的最大溫度差分別帶入第一回歸直線方程式的變數X1、X2以及X3,並經運算後得到變數Y的數值,且此變數Y的數值可視作測試布料的色差值△E。 After the dyeing process is completed, the process proceeds to step S40. In step S40, whether the dyeing result of the test cloth is qualified can be verified by substituting the test data of the test cloth into the first regression linear equation. Specifically, the maximum temperature difference of each color light obtained in step S30 at the coloring rates of 20%, 50%, and 90% can be brought into the variables X 1 , X 2, and X 3 of the first regression linear equation, respectively, and The value of the variable Y is obtained after the calculation, and the value of the variable Y can be regarded as the color difference value ΔE of the test cloth.
接著,可根據測試布料的染程屬性與色差值△E判斷染色結果是否合格。染程屬性會依染料總濃度而分成淺染、中染以及重染,其中染料總濃度的定義為染程中所有使用的染料相加後的濃度。例如,當染程使用了第一染料0.3重量%以及第二染料0.5重量%,則染料總濃度就會是0.8重量%。於此定義下,染料的總濃度小於或等於0.5重量%則為淺染,染料的總濃度大於0.5重量%並小於或等於1.5重量%則為中染,而染料的總濃度大1.5重量%則為重染。 Then, it can be judged whether the dyeing result is acceptable or not according to the dyeing process property of the test cloth and the color difference value ΔE. The properties of the dyeing process are divided into light dyeing, medium dyeing and re-dyeing according to the total dye concentration. The total dye concentration is defined as the concentration of all the dyes used in the dyeing process. For example, when 0.3% by weight of the first dye and 0.5% by weight of the second dye are used in the dyeing process, the total dye concentration will be 0.8% by weight. Under this definition, the total concentration of dyes is less than or equal to 0.5% by weight, which is light dyeing, the total concentration of dyes is greater than 0.5% by weight, and less than or equal to 1.5% by weight, is medium dyeing, and the total concentration of dyes is 1.5% by weight. For restaining.
在一些實施方式中,當測試布料為淺染時,測試布料的色差值△E小於或等於0.6則判定為合格,當測試布料為中染時,測試布料的色差值△E小於或等於0.8則判定為合格, 當測試布料為重染時,測試布料的色差值△E小於或等於1.0則判定為合格。 In some embodiments, when the test cloth is lightly dyed, the color difference value ΔE of the test cloth is less than or equal to 0.6, it is judged as a pass. When the test cloth is medium dyed, the color difference value ΔE of the test cloth is less than or equal to 0.8 is judged as passing, When the test cloth is re-dyed, if the color difference value ΔE of the test cloth is less than or equal to 1.0, it is judged as passing.
當測試布料的色差值未被判定為合格時,可進入步驟S50。在步驟S50中,可對未被判定為合格的測試布料依據其分光曲線分布圖提供染程建議,例如調整上色速度(或分光曲線分布圖的上色斜率)、調整染料配方(例如包括染料濃度及助劑種類等)及調整持溫時間等。接著,當提供染程建議之後,可再次進入步驟S30,從而使用所提供的染程建議進行再一次染程,此後所進行的步驟前述相同,在此不再贅述。 When the color difference value of the test cloth is not judged to be acceptable, the process may proceed to step S50. In step S50, it is possible to provide a dyeing process recommendation for the test cloth that is not judged to be qualified according to its spectral curve distribution chart, such as adjusting the coloring speed (or the coloring slope of the spectral curve distribution chart), adjusting the dye formula (for example, including dyes) Concentration and types of additives, etc.) and adjustment of holding time. Then, after providing the dyeing process proposal, the process may proceed to step S30 again, so as to perform the dyeing process again using the provided dyeing process proposal. The steps performed thereafter are the same as above, and are not repeated here.
另一方面,不論測試布料的染色結果是否被判定為合格,可再進入步驟S60。在步驟S60中,可將測試布料的測試數據匯入至資料庫。例如,原先資料庫的數據為6000筆,則在將測試布料的測試數據匯入至資料庫後,資料庫的數據會更新為6001筆。接著,可再進入步驟S20,並利用更新後的資料庫來建立第二回歸直線方程式,其中第二回歸直線方程式的形式會與第一回歸直線方程式的形式相同,且其變數的定義也相同。第二回歸直線方程式可取代第一回歸直線方程式,亦即步驟S40所使用的驗證工具更改為第二回歸直線方程式。 On the other hand, regardless of whether the dyeing result of the test cloth is judged to be acceptable, the process may proceed to step S60 again. In step S60, the test data of the test cloth can be imported into the database. For example, the original database contains 6000 data. After importing the test cloth test data to the database, the database data will be updated to 6001. Then, it can proceed to step S20 and use the updated database to establish a second regression line equation, wherein the form of the second regression line equation will be the same as that of the first regression line equation, and the definitions of the variables will be the same. The second regression line equation may replace the first regression line equation, that is, the verification tool used in step S40 is changed to the second regression line equation.
於後續步驟中,當再次對布料進行染色的時候,除了可使用第二回歸直線方程式來驗證此布料的染色結果是否為合格以外,可再自所進行的染程擷取數據,並將擷取到的數據匯入至資料庫進行更新,從而擴大料庫的樣本筆數。同樣地,可利用更新後的資料庫來建立第三回歸直線方程式,並取代第二回歸直線方程式。透過此機制,驗證方法所使用的回歸 方程式會逐次更新,從而達到機器學習的效果。此外,上述步驟除了所使用的量測元件以外,各步驟的邏輯處理可由電子計算機進行。 In the subsequent steps, when the cloth is dyed again, in addition to using the second regression linear equation to verify whether the dyeing result of this cloth is acceptable, data can be retrieved from the dyeing process performed, and The obtained data is imported into the database for updating, thereby increasing the number of samples in the material library. Likewise, a third regression linear equation can be created using the updated database and replaced by the second regression linear equation. Through this mechanism, the regression used by the validation method The equations are updated one by one to achieve the effect of machine learning. In addition to the above steps, in addition to the measurement elements used, the logical processing of each step can be performed by an electronic computer.
綜合上述,本揭露內容提供一種染色製程的驗證方法,其可在不同染程進行期間,對布料或染液進行數據擷取,從而建立資料庫,並藉由資料庫產生回歸方程式做為驗證工具。當進行新的染程時,利用回歸方程式即可判讀出所進行的染程的染色結果是否合格。在未被判讀為合格的情況下,可進一步對此染程提供建議,從而做為下一次的染程參數的依據。此外,不論染色結果是否被判讀為合格,染色結果會被匯入至資料庫,以回饋並再次修正回歸方程式,從而達到機器學習的效果。藉由此機制,可使對染色製程結果的判斷為數據分析,從而防止染色結果與預期顏色有所差異的狀況發生。 To sum up, this disclosure provides a method for verifying the dyeing process, which can collect data on cloth or dyeing liquid during different dyeing processes, thereby establishing a database, and using the database to generate regression equations as a verification tool. . When a new dyeing process is performed, the regression equation can be used to judge whether the dyeing results of the performed dyeing process are acceptable. If it is not judged as qualified, it can further provide suggestions for this dyeing process, so as to be the basis for the next dyeing process parameters. In addition, regardless of whether the staining result is judged as qualified, the staining result will be imported into the database to feedback and modify the regression equation again, so as to achieve the effect of machine learning. Through this mechanism, the judgment of the result of the dyeing process can be analyzed by data, thereby preventing the situation where the dyeing result is different from the expected color.
