Description

Technical Field

[0001] This utility model relates to the field of textile display color change detection, and in particular to a textile display color change testing device. Background Technology

[0002] Textiles, especially clothing and bedding, are susceptible to environmental influences and quality problems during display, such as discoloration, which manifests as fading, yellowing, or reddish discoloration, making the products unsellable. Therefore, when displaying textiles, it is usually necessary to conduct a preliminary risk assessment in order to adjust the display plan and reduce the risk of discoloration.

[0003] Existing risk assessment methods for textile display discoloration mainly involve establishing corresponding independent risk assessment tools for specific influencing factors, such as: GB / T 30669-2014 UV light yellowing fastness, HG / T 3689-2014 sunlight yellowing fastness, GB / T 8427-2019 light fastness test assessment, and GB / T 11039.3-2005 textiles color fastness to atmospheric pollutants and GB / T 29778-2013 potential phenolic yellowing of textiles. These methods yield corresponding risk assessment results. However, in real-life scenarios, textile display discoloration is often the result of multiple factors working together. Conducting independent risk assessments for only a specific influencing factor leads to significant deviations between the risk assessment results and the actual situation, resulting in low accuracy.

[0031] Please refer to Figure 1 This utility model provides a textile display color change test device, including an experimental chamber 1, an ozone generator 5, a temperature control system 6, a humidity control system 7, a scale 3, a light source 2, and a sample rack 4.

[0032] The sample holder 4 is disposed inside the experimental chamber 1;

[0034] The temperature control system 6 is connected to the experimental chamber 1 and is used to regulate the temperature inside the experimental chamber 1;

[0035] The humidity control system 7 is connected to the experimental chamber 1 and is used to adjust the humidity inside the experimental chamber 1;

[0036] The light source 2 is installed on the top of the inner wall of the experimental chamber 1;

[0037] The scale 3 is provided with multiple limiting protrusions at equal intervals. The sample holder 4 is installed above the limiting protrusions. By installing the sample holder 4 on the limiting protrusions at different heights, the distance between the test sample and the light source 2 can be adjusted.

[0038] During use, the temperature inside the test chamber is (15℃~50)℃, the relative humidity is (50~80)%, the ozone concentration is (1.0~5.0)ppm, and the fluorescent lamp is (15~45)W. Cut a (40±2)mm×(100±2)mm sample from the undiscolored part of the sample with quality problems and from any part of the sample without quality problems. Lay the sample flat on the sample rack. After the specified test time, immediately take the sample out of the test chamber and compare it with the original sample. Use a gray scale or instrument to evaluate the discoloration of the sample. This can effectively assess the risk of discoloration of textiles caused by the combined effects of multiple factors when displayed.

[0039] Samples were taken from the uncolored areas of the samples with quality problems and from any areas of the samples without quality problems. The device of this application was then used to conduct a color change test on the textile display. The analysis of the matching degree between the test and the sample results showed that the device can efficiently, quickly, accurately and objectively reflect the potential color change risk of textile displays.

[0040] In this embodiment, the light source 2 includes two fluorescent lamps, one ultraviolet lamp, and one spotlight, which can provide different types, wavelengths, and power of illumination as needed.

[0041] In this embodiment, an observation window is provided on the surface of the experimental chamber 1, and a transparent glass is provided inside the observation window, through which the color change of the sample can be observed intuitively.

[0042] In this embodiment, the experimental chamber is equipped with a circulating air duct to ensure that the airflow inside the experimental chamber is uniform and stable.

[0043] In this embodiment, the ozone generating mechanism 5 includes an ozone generator, a pressure reducing valve, and a flow meter. The pressure reducing valve is connected to the ozone generator through a first pipeline, and a flow meter is installed on the first pipeline. The ozone generator is connected to the experimental chamber 1 through a second pipeline.

[0044] The working principle of this utility model is as follows:

[0045] By adjusting parameters such as temperature, relative humidity, ozone concentration, and light intensity within the experimental chamber, the color change of samples under different display conditions can be tested. After the test, the sample is immediately removed from the experimental chamber and compared with the original sample. The color change of the sample is evaluated using a gray scale or instrument, which can effectively assess the risk of textiles changing color due to the combined effects of multiple factors during display.
