Problems solved by technology

[0007] Another technical problem to be solved by the present invention is: use the CIEDE2000 color difference formula or the CIE94 color difference formula to obtain all the color difference values ​​of the target color and the existing color data in the database, replace the manual color comparison with a computer-specific module, and use the quantified color difference Value to replace the color difference obtained by naked eye colorimetry, and select the sample and its formula data closest to the target color from the database, simplify the traditional color matching process, and improve the color matching accuracy

Embodiment 1

[0034] Such as figure 2 As shown, it is a schematic diagram of the composition and structure of the system used in the method for measuring and matching color of pre-spinning colored fibers in this embodiment: 1 is the DigiEye color measuring system; 2 is a computer host with computing power; 5 is a display connected to the host computer for displaying formula information and object images in the database; 4 is the actual coloring fiber sample produced before spinning according to the optimized formula of the method for measuring color matching of the present invention.

[0035] Such as figure 1 As shown, a kind of pre-spinning colored fiber measuring and matching method of the present embodiment comprises the following steps:

[0036] (1) Establish a database for the relevant data of the existing pre-spinning colored fiber samples.

Embodiment 2

[0048] (1) Establish a database for the relevant data of the existing pre-spinning colored fiber samples.

[0049] The produced pre-spun colored fiber is evenly wound on the glass slide. During the winding process, the surface of the filament needs to be kept flat to ensure the accuracy of the color measurement data. The glass slide wound with the pre-spun colored fiber is passed through the The DigiEye color measurement system of British Verivide company obtains the color data and sample image of the pre-spun dyed fiber sample, and builds a database for the color data (Lab value and RGB value) and image of the sample. The establishment and management of the database can be done through Microsoft Office Access 2007 database software. At the same time, the formula information (selection and proportion of raw material masterbatch) of the above samples is also imported into the established database, and the sample number is used as the only mapping method between the two.

Abstract

The invention discloses a pre-spinning-colored fiber color testing and matching method. The pre-spinning-colored fiber color testing and matching method comprises the following steps of (1) establishing a database for related data information of an existing pre-spinning-colored fiber sample; (2) measuring color data of a target sample; (3) comparing the color data of the target sample with the color data in the database; (4) displaying and finely adjusting an optimal recipe; (5) testing the color data of a final sample, and expanding and optimizing the database. According to the pre-spinning-colored fiber color testing and matching method disclosed by the invention, computer management on recipe data and sample color data is realized on the basis of establishing the database, not only are important data prevented from losing, but also the data safety is ensured; a color difference operation formula is operated by a computer, so that a great number of tedious manual work can be reduced, and the accuracy rate can be increased; the data volume of the database can be expanded by the final sample again, so that the accuracy of color matching next time is increased.

Description

technical field [0001] The invention relates to a color matching method for pre-spinning colored fibers. It specifically relates to color measurement of pre-spinning colored fibers, management of color masterbatch formula and color matching method, and belongs to the field of digital management of pre-spinning coloring processing technology. Background technique [0002] The traditional textile process is: fiber-spinning-weaving-dyeing-clothing, and the dyeing process consumes a lot of energy and causes serious pollution to the environment. Pre-spinning coloring is to add coloring agent to form colored fiber in the polymerization process or spinning process, usually color masterbatch is used for coloring, after the spinning screw is melted, stirred and extruded, the colorant is evenly dispersed in the fiber In this way, the serious pollution and high energy consumption caused by traditional dyeing methods can be avoided. [0003] At present, the global masterbatch producti...
