Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0036] The embodiment of the present application provides a method for evaluating the light fastness of yarn-dyed fabrics, such as figure 1 As shown, the method includes the following steps:

[0037] Step S102, acquiring the basic fastness value of the yarn-dyed fabric.

[0038] Among them, the basic fastness value of yarn-dyed fabric can be defined as the light fastness of the yarn of the main color in the yarn-dyed fabric that affects the light fastness of the fabric, and the determination of the main color can be the proportion of the corresponding color in the patter...

Abstract

The invention relates to a method for evaluating the sunlight fastness of yarn-dyed cloth, a device and a computer device, wherein the method comprises the following steps: obtaining a basic fastnessvalue of the yarn-dyed cloth and a ratio of a color to an area of the yarn-dyed cloth corresponding to the basic fastness value; Determining a fastness correction value of the yarn-dyed cloth according to the ratio of the color corresponding to the base fastness value to the area of the yarn-dyed cloth; The overall fastness value of the yarn-dyed cloth is determined according to the basic fastnessvalue and the fastness correction value of the yarn-dyed cloth. By obtaining a basic fastness value of the yarn-dyed fabric and a ratio of a color corresponding to the basic fastness value to the area of the yarn-dyed fabric, so as to determine the fastness correction value of the yarn-dyed cloth according to the ratio of the color corresponding to the base fastness value to the yarn-dyed cloth area, and further calculate the overall fastness value of the yarn-dyed cloth according to the base fastness value and the fastness correction value of the yarn-dyed cloth. The method does not need tocarry out destructive tests on yarn-dyed fabrics, and can realize accurate evaluation of the dye-dyed fabrics' fastness to sunlight, thus avoiding waste of resources.

Description

technical field [0001] The present application relates to the technical field of yarn-dyed fabric quality inspection, in particular to a method, device and computer equipment for evaluating the light fastness of yarn-dyed fabric. Background technique [0002] With the rapid development of the textile industry, the evaluation of the light fastness of yarn-dyed fabrics is also particularly important. At present, the evaluation method of the textile industry for the light fastness of yarn-dyed fabrics mainly relies on actual tests, and the test needs to monitor the various processes from the yarn count to the formation of yarn-dyed fabrics, and requires destructive testing of yarn-dyed fabric samples. The test can only be obtained. [0003] However, with the improvement of customer demand, if we wait until the yarn-dyed fabric comes out and then arrange the corresponding destructive test for testing, the development cycle will be extended a lot. Cloth can no longer be used, r...
