Problems solved by technology

However, in the existing instruments for testing the whiteness value and K / S value, only local points of the textile can be measured, and the overall measurement of the entire textile cannot be realized, and the test results cannot reflect the partial color fading of the textile during the washing process.
[0003] In addition, due to the complex colors of transfer printed textiles, the objective and accurate evaluation of color fastness to soaping has always been a bottleneck problem that plagues transfer printing technology.

Embodiment Construction

[0013] According to the requirements in GB / T3921-2008, when the sample is a fabric, prepare a combined sample according to the following method: take a piece of transfer printing textile sample with a size of 100 mm × 40 mm, and a piece of pure cotton fiber with a size of 100 mm × 40 mm on the front The white facing fabric touches and is stitched along one short edge. In this example, in order to simulate the real laundry fading environment and ensure the stability of the test, five samples were washed at one time with a domestic rolling washing machine. For example, using figure 1 Shown hardware fits figure 2 The shown software takes photos of the transfer printing textile samples dried before and after washing, and calculates the average gray value I of the sample images before and after washing. b and I a . According to the principle of machine vision, the color of the sample fades after washing, the color becomes lighter, and its gray value becomes larger. Therefore,...

Abstract

The invention relates to a transfer printing textile soaping color fastness evaluating method based on machine vision, which realizes global, fine and objective evaluation of the soaping color fastness of the transfer printing textile with a complicated color pattern structure. The transfer printing textile soaping color fastness evaluating method based on machine vision is realized by a hardware part and a software part in a coordinating way. The hardware part can be used for obtaining images of the transfer printing textile and mainly comprises an industrial video suite (1), a light source (2), a light source controller (3), a computer mainframe (4), a display (5), a data transmission lead (6) and a test sample bench (7), wherein the test sample bench is used for mounting the industrial video suite and the light source; and the software part can be used for obtaining, saving and cutting images, making a statistic of gray characteristics as well as evaluating transfer printing textile soaping color fastness grades and pure cotton fiber white accompanying test sample staining grades.

Description

technical field [0001] The present invention relates to a method for evaluating the color fastness to soaping of transfer printing textiles based on machine vision. Degree" and GB / T 3921-2008 "Textile Color Fastness Tests Color Fastness to Soaping" stipulates that based on the gray sample card or instrument, compared with the original sample, the fading of the sample is compared with the staining method of the adjacent fabric. Compared with the method proposed by the invention, it is more objective and accurate, and can effectively reduce the error caused by subjective judgment. Background technique [0002] Transfer printing has the characteristics of low labor intensity, high production efficiency, and strong adaptability to fabrics. It can obtain the effect of lively patterns and bright colors, and is widely used in textile printing. The evaluation of color fastness to soaping is an important part of the quality evaluation of transfer printed textiles. For all printed fa...
