Description

Integrated color prescription calculation system and calculation method

The present invention relates to an integrated color prescription calculation system and calculation method.

In general, the textile industry is likely to shrink due to environmental regulations due to high pollution loads and excessive energy consumption by manufacturing streams. In particular, the dyeing process, which is one of the main streams of the textile industry, is a process of removing impurities from fibers and giving them a performance suitable for aesthetic color and use purpose, and is a step of providing the highest added value in the textile manufacturing process.

However, most dyeing and processing companies are small and medium sized companies that process dyeing in the form of forestry. If reinfection occurs due to uneven dyeing and color difference of dyeing, economic loss occurs due to deterioration of productivity and quality, increase of pollutants and energy usage. In order to solve the problems of dye companies, it is necessary to select the optimal dyes and preparations for dyeing conditions and to optimize the dyeing process. In addition, it is important to introduce a technique for systematic color management of products produced in the field, and representative management with IT is proposed.

In order to manage the production system using IT, Japan established a low energy and eco-friendly dye processing color support center. This enables networking and color prescription data in the laboratory, pilot, and field, including web-based color sample data hardware and software systems, color data bank-based color information service technology, color matching and digital color information processing technology, and more. We have established a technology that can deliver the information on the web. However, it is not only limited to the dyeing process but also not particularly related to fiber dyeing. In addition, the center was built around related companies that needed it, and now the center's operators have changed due to abandonment and change of business area.

In Europe, there is Dyestar's 'Optidye System', but the DB is composed only of Dyester's own dyes, and it is a limited and limited dye preservation system that supports only companies using its dyes.

In the case of Datacolor's Integrated Color Management (ICM) in the United States, its influence has been greatly increased in the textile dyeing field. ICM completed the ICM by operating color as the most basic element by sharing information with the controller companies and ERP companies related to the dyeing plant laboratories and the facility companies in the field, but the company itself produces any system or equipment related to dyeing. There is no verification such as color difference and reproducibility improvement when dyeing.

Accordingly, the present invention provides an integrated color prescription calculation system and calculation method capable of integrating, managing and analyzing various dyeing variable data to calculate color prescription for dyeing suitable for a laboratory and a site.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise.

Hereinafter, an integrated color prescription calculation system and a calculation method according to an embodiment of the present invention will be described with reference to the drawings.

Before describing the embodiments of the present invention, a general dyeing procedure will be described with reference to FIG.

1 is a flow chart for a general staining process.

As shown in FIG. 1, when a buyer requests a desired color sample from a dyeing company (S10), the dyeing laboratory uses the laboratory's CCM (Computer Color Matching) and the operator's experience value in order to know the dyeing prescription of the color sample. Make a dyeing prescription (S11). And after the preparation of the laboratory CCK (S12), the BT staining in the laboratory (S13). Compare the dyed color with the buyer's desired color (S14), and if it is out of tolerance, repeat the process of preparing and dyeing the dyeing step S11 again.

If the color difference is within the tolerance, spot dyeing is performed (S15). Stop the dyeing machine in the middle of the dyeing site, take a portion of the dyeing fabric and compare it with the BT color (S16). If outside the tolerance, the dye should be added and redyed according to step S15 according to the experience of field workers. If it is within the tolerance, the operation is completed (S17).

In other words, the buyer first sends a color sample to the dyeing company's laboratory, where the shape of the color sample conveys various information such as thread, fabric, paper, and color data. The size of the color sample varies as well as the shape of the color sample. The shape of the color sample varies depending on the buyer such as a few strands of thread, a size as small as a nail, and an A4 size. If the color sample is large, you know exactly what the color is, but this is rarely the case, and most color samples are very small.

Once the buyer's color sample is received, the dye factory's laboratory measures the color sample with CCM equipment to obtain an approximate dyeing recipe to determine how much dye is added. Based on the approximate value of the CCM and the operator's experience, primary dyeing is carried out in the laboratory, which is called BT (Beaker Test) dyeing.

The BT dyeing results are compared with the buyer's color samples and if there is a color difference, the 1st dyeing prescription is corrected and the second dyeing is performed. This BT staining and color sample comparison operation continues until the color difference value falls within the tolerance range. Experienced workers in the lab will match the color sample with 3-4 BT dyes, but if they are inexperienced, BT staining should be repeated until the color is correct.

One-time BT dyeing takes about two hours for cotton fabrics, but for beginners it may take 1-2 days to match the desired color. In order to proceed with BT dyeing, which is directly linked to production, dyeing laboratories are making efforts to store dye samples and to purchase expensive dyeing prescription equipment and use dyes with excellent reproducibility. However, when the desired color comes out, various data generated during the BT dyeing process (for example, dyeing conditions, fabric properties, modified dye prescription, dye addition ratio, etc.) will be lost its usefulness.

In the case of spot dyeing, when color prescription obtained through BT dyeing is applied to the spot as it is, there are many cases of color difference due to the difference in dyeing size and working environment between the laboratory and the spot. To reduce the color difference between the laboratory and the site, stop the dyeing machine during dyeing, take a portion of the dyeing fabric, and compare the color with the BT dye sample of the buyer's desired color. If there is a difference in the comparison, the dye to be added and the amount to be added is determined by the experience of the field operator. Many data generated in the field during in situ staining are not managed as systematically as in the laboratory.

The integrated prescription calculation system according to the embodiment of the present invention shares information such as resources for each facility of the dyeing laboratory and the field and utilizes the integrated prescription calculation system 100, color, BT number, fabric of the dyeing parameters of the laboratory Based on data on material, composition, organization, dyeing conditions and dyeing process, liquid ratio, and data on fabric weight, water usage, liquid ratio, dyeing machine characteristics, dyeing method, etc. The optimal dyeing prescription can be calculated according to the laboratory and the site. This will be described with reference to the drawings.

As shown in FIG. 2, the integrated color prescription calculation system 100, which is interlocked with the CCM devices provided in one or more laboratories and the equipment provided in one or more sites, includes a data input unit 110 and integrated data. The storage unit 120, the prescription calculator 130, the prescription presenter 140, and the CCM measurer 150 are included. The data input unit 110 includes a first data input unit 111, a second data input unit 112, and a third data input unit 113, and the prescription presenting unit 140 includes the first prescription presenting unit 141 and the second. The prescription presenting unit 142 is included.

The data input unit 110 inputs a first data input unit 111 for receiving first data generated in a laboratory, a second data input unit 112 for receiving second data generated in a field, and third data for a dye raw material. Receiving third data input unit 113 is included.

In this case, the first data, which is laboratory data, includes color to be dyed in a laboratory, BT number, fabric characteristic information (for example, fabric material, composition, and tissue information), dyeing prescription for dyes used, dyeing process, liquid ratio. Information and the like. The second data, which is the field data, includes information on the field dyeing such as the weight of the fabric to be dyed in the field, the amount of water used, the liquid ratio, the dyeing machine number, and the dyeing method.

The third data, which is the dye raw material data, is related to the absorption rate, temperature, preparation (e.g., forget-me-not, alkali, acetic acid, leveling agent, dispersant, etc.) related to the dyeability of the dye raw material used, Buildup property, liquid ratio. Includes information about the impact on. The third data uses different dyes, depending on the company that uses the dye, usually about 10 dyes for each of the four types (eg reactive, acidic, dispersed, direct dyes).

Therefore, the lab worker may generate and input third data for different dyes in advance, or purchase and input from a provider providing the data. The third data may be updated for each period. In addition, in the embodiment of the present invention, the first data, the second data, and the third data are not limited to only the above-mentioned information.

The integrated data storage unit 120 integrates and stores the first data, the second data, and the third data input by the data input unit 110. In addition, when the prescription calculation unit 130 to be described later receives the prescription request information transmitted from any one of the laboratory or the field, the integrated data storage unit 120 is the first data, the second data corresponding to the prescription request information And search for the third data and provide it to the prescription calculating unit 130. In addition, when the CCM measurement result is received from the CCM measurement unit 150 to be described later, information indicating a color similar to the sample color is provided to the CCM measurement unit 150.

When the prescription calculating unit 130 receives the CCM result value and the retrieved data from the CCM measuring unit 150, the prescription calculating unit 130 calculates a first correction value that is a dye correction value to be used in a laboratory and a second correction value that is a dye correction value to be used in the field. The prescription calculator 130 calculates the dyeing prescription information to be used in the laboratory and the dyeing prescription information to be used in the field based on the calculated first correction value and the second correction value. Here, each correction value will be described as an example of calculating a correction value by applying a laboratory prescription variable or an on-site prescription variable to the retrieved data received from the CCM measuring unit 150. However, the method of calculating the correction value or the method of calculating the prescription according to the item may have various methods, and thus embodiments of the present invention are not limited to one method.

The prescription presenting unit 140 provides the prescription information calculated from the prescription calculating unit 130 to the laboratory or the site that generated the prescription request information. To this end, the prescription presenting unit 140 includes a first prescription presenting unit 141 for providing information to the laboratory and a second prescription presenting unit 142 for providing information to the field. However, the prescription presenting unit 140 may provide prescription information according to the situation.

When the sample of the buyer is received, the CCM measuring unit 150 measures the CCM from the received sample and provides the measured CCM result information to the integrated data storage unit 120. In addition, data about a color similar to the color of the sample received from the integrated data storage unit 120 is received and provided to the user.

A method of calculating the prescription color prescription using the integrated color prescription calculation system 100 described above will be described with reference to FIG. 3.

As shown in FIG. 3, when the sample of the buyer is received, the CCM measuring unit 150 measures the CCM for the received sample (S100), and provides the measured result information to the integrated data storage unit 120. Search for information about the color similar to the color (S110). The information on the similar colors in step S110 includes first data as laboratory prescription variables, second data as field prescription variables, and third data as dye base material data information.

The prescription calculator 130 calculates a first correction value, which is a laboratory correction value to be used in a laboratory, and a second correction value, which is a field correction value to be used in the field, based on the CCM value measured in step S100 and the information retrieved in step S110 (S120). And the prescription calculation unit 130 calculates the optimal laboratory dye prescription value using the laboratory correction value calculated in step S120 (S130), and calculates the optimal field dye prescription value using the field correction value calculated in step S120. It calculates (S140).

Steps S130 and S140 of the color prescription calculation method described above will be described with reference to FIG. 4 in more detail.

As shown in FIG. 4, when the sample of the buyer is received, the CCM measuring unit 150 measures the CCM for the received sample (S200), and provides the measured result information to the integrated data storage unit 120. Search for information about the color similar to the color (S210). The information on the similar color in step S210 includes first data, which is a laboratory prescription variable, second data, which is a field prescription variable, and third data, which is dye base material data information.

The prescription calculating unit 130 calculates a first correction value which is a laboratory correction value to be used in a laboratory and a second correction value which is a field correction value to be used in the field, based on the CCM value measured at step S200 and the information retrieved at step S210 (S220). Then, the prescription for the lab and the prescription for the field are calculated separately.

Generally, dyeing companies calculate prescriptions in the laboratory and use the calculated prescriptions as they are in the field. In such a case, when the cotton reactive dyeing or blend dyeing in the field, there is a lot of difference from the color predicted by the laboratory.

That is, in the case of synthetic fibers (for example, nylon, PET, etc.) when dyeing with acid dyes and disperse dyes, when the laboratory prescription is applied on-site as it may fit well. However, in recent years, because dyeing a lot of blended fibers (for example, mixed with cotton and PET, or mixed with PET and rayon), when the laboratory prescription is applied to the field as it is, there are a lot of color differences and dyeing accidents.

Correcting the color difference caused by dyeing with the color prescription for lab-provided dyeing, the workers in the field stop the dyeing machine during the dyeing process and take a part of the dyed fabric and compare it with the laboratory color with the naked eye or CCM. If the colors are different, the amount of additional dye and its amount is determined by the experience of the field operator, and the dye is added to the dye. This process is repeated until the same color as the laboratory.

The reason for the color difference in the case of applying the laboratory dyeing prescription as it is is because the prescription calculation database and the laboratory dyeing conditions for calculating the dyeing prescription in the laboratory are different from the site. In other words, the laboratory's prescription calculation database is a fabric that has been pre-treated in the laboratory, and puts a triangular flask in a shaking water bath that keeps water at a constant temperature as a heat medium while moving from side to side in the laboratory, and then puts the saline solution and the fabric at once. Dyeing or rotating up and down, using an IR dyeing machine that maintains a constant temperature with infrared rays as a thermal medium, the stainless pot is put into the dye solution and fabrics are made using the dyed samples.

The biggest difference among the various dyeing conditions in the laboratory and the field is liquid fertilization, which is difficult to check the exact color due to disproportionation when dyeing with liquid ratio less than 10: 1. In other words, most laboratory dyeing machines (water bath, IR dyeing machine, etc.) are stained with less than 10: 1 liquid ratio, so there is a small amount of salt solution, and there is a high possibility of disproportionation. Therefore, the laboratory dyes with a liquid ratio of at least 10: 1 and uses the sample to make a database for calculating the laboratory dye prescription.

Using the lab dye calculation DB made in this way, the color sample sent by the buyer is measured by CCM equipment to calculate the lab dyeing prescription, but it is well suited when calculating the dyeing prescription on site. Yes, but if you dye it on-site, it is likely to dye in a completely different color. In order to calculate the spot staining prescription, it is necessary to utilize the spot staining prescription database created in the field to calculate the prescription for the exact spot staining conditions.

However, in order to calculate the optimal prescription for the field, laboratory data variables, field data variables, and dye raw material data information are integrated and stored in the integrated database. The site must calculate the appropriate prescription for the site to reduce the color difference between the lab and the site.

To this end, in the embodiment of the present invention, when the prescription calculation unit 130 calculates the laboratory correction value and the field correction value in step S220, the field matching correction value is applied to the information retrieved in step S210 (S230). In addition, the prescription calculating unit 130 calculates the on-site prescription by applying the correction value to the information (S231). The second prescription presenting unit 142 provides the spot prescription calculated in step S231 to the spot, so that the dye in the spot through the prescription (S232).

At the same time, if the prescription calculation unit 130 calculates the laboratory correction value and the field correction value in step S220, the laboratory matching correction value is applied to the information retrieved in step S210 (S240). The prescription calculator 130 calculates a laboratory prescription by applying the correction value to the information (S241). The first prescription presenting unit 141 provides the on-site prescription calculated in step S241 to the laboratory to be dyed in the laboratory through the prescription (S242).

In FIG. 3, although the color prescription for dyeing to be used in the laboratory is calculated in step S130, the color prescription for dyeing to be used in the field is calculated through the step S140. It may be made in parallel as in step S242.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.
