BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Figure 1 It is a flowchart of an embodiment of the experimental test method for clothing fabrics provided by the present invention.

[0045] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0046] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] The present invention provides an experimental test method for clothing fabrics.

[0048] Please refer to Figure 1 , in the technical solution of the present invention, the experimental test method for clothing fabrics includes randomly selecting a product to be tested and intercepting a sample from the product to be tested; clamping the intercepted sample and placing the sample horizontally; lifting the sample to a preset height h 0 ; Lift the counterweight to directly above the sample, with a height of H, where H > h 0 ; Drop the counterweight freely onto the sample; Rotate the sample to make it vertically placed, spray methyl orange reagent on one side of the sample and let it stand for a preset time; On the side of the sample where methyl orange reagent is not sprayed, spray a quantified sodium hydroxide solution; Immediately start timing after spraying is completed; Stop timing when the sample starts to change color; Analyze the waterproof performance of the sample after impact wear according to the timing duration measured by the timer.

[0049] By dropping a counterweight freely onto the sample, the present invention simulates the wear that the clothing may suffer during the exploration of explorers, and can truly reflect the wear effect in the actual use scenario; then uses the color reaction of methyl orange reagent with alkaline substances to test the waterproof performance of the worn sample, and analyzes the waterproof performance of the worn sample according to the duration of color change, so that the waterproof performance of the clothing after wear can be effectively tested.

[0050] It should be noted that the color reaction principle of methyl orange reagent with alkaline substances is mainly based on its property as an acid-base indicator. Methyl orange is a weakly basic organic compound with a color change range between pH 3.1 and 4.4. In an acidic environment, methyl orange appears red; while in an alkaline environment, it appears yellow. This color change is due to the sensitivity of the aromatic ether group and methylbenzene group in the molecular structure of methyl orange to hydrogen ions. In the experimental test method, when the methyl orange reagent contacts the sodium hydroxide solution, a color reaction occurs. This is because methyl orange transforms into its yellow form in an alkaline environment, and this color change can be used to judge the waterproof performance of the sample. When the methyl orange reagent is sprayed on one side of the sample and left standing, and then sodium hydroxide solution is sprayed on the other side, if the waterproof performance of the sample is good, the sodium hydroxide solution will not penetrate to the side of the methyl orange reagent, so no color change will occur. If the waterproof performance of the sample is damaged, the sodium hydroxide solution will penetrate through and contact the methyl orange reagent, resulting in a color change, thereby enabling the analysis of the waterproof performance of the sample after being impacted and worn.

[0051] In an embodiment of the present invention, the step of randomly selecting a product to be tested and intercepting samples from the product to be tested includes intercepting three samples on the same product; lifting the samples to a preset height h 0 ; lifting the counterweight to directly above the samples, with a height of H, where H > h 0 The step of includes lifting all three samples to the preset height h 0 ; lifting three counterweights with the same mass to directly above the three samples respectively, with heights of H 1 、H 2 、H 3 , where H 1 >H 2 >H 3 . By setting different heights H1, H2, and H3, the degree of wear caused by the free fall of counterweights at different heights on each sample is different, so that the influence of different degrees of wear on the waterproof performance of the sample can be simulated, and thus the waterproof performance of the product under different degrees of wear can be evaluated.

[0052] In an embodiment of the present invention, the step of randomly selecting a product to be tested and intercepting a sample from the product to be tested further includes randomly selecting three products at a time and intercepting samples from the same position of the three products. Intercepting samples from the same position of three different products can ensure the consistency of the samples before testing and reduce the difference in test results caused by different sample positions; since all samples are from the same position, the comparison between test results is more fair and accurate, facilitating the analysis and comparison of the performance of different products; intercepting samples from multiple products can more comprehensively evaluate the overall performance of the products, especially in large-scale production, which helps to discover possible batch differences; this method helps to quickly identify potential problems in the production process, facilitating timely quality control and adjustment.

[0053] In an embodiment of the present invention, the step of aligning the side of the sample that has not been sprayed with methyl orange reagent and spraying a quantitative amount of sodium hydroxide solution includes that the temperature of the sprayed sodium hydroxide solution is 26 - 28 °C. Methyl orange, as an acid-base indicator, its color change range is affected by temperature. At different temperatures, the color change range of methyl orange will change. For example, at 18 °C, the color change range of methyl orange is 3.1 - 4.4, while at 100 °C, the color change range becomes 2.5 - 3.7. Therefore, in order to ensure the accuracy and consistency of the color reaction, it is necessary to control the temperature of the sodium hydroxide solution within a suitable range. Within the temperature range of 26 - 28 °C, the reaction rate between the sodium hydroxide solution and methyl orange is moderate, neither being too slow due to too low a temperature nor being too fast due to too high a temperature, making it difficult to observe the color change.

[0054] In an embodiment of the present invention, the step of rotating the sample to make it vertically placed, spraying methyl orange reagent on one side of the sample and standing for a preset time includes that the preset standing time is 10 - 15 min. Setting the standing time to 10 - 15 minutes can ensure that the methyl orange reagent is in full contact with the surface of the sample, enabling the methyl orange reagent to fully infiltrate one side of the sample for a more accurate test of the waterproof performance.

[0055] In an embodiment of the present invention, the step of randomly selecting a product to be tested and intercepting a sample from the product to be tested further includes that the shape of the sample intercepted from the product to be tested is circular; the step of aligning the side of the sample that has not been sprayed with methyl orange reagent and spraying a quantitative amount of sodium hydroxide solution further includes spraying the sodium hydroxide solution towards the center of the sample. The circular sample provides a standardized test sample shape, which helps to maintain the consistency of each test; spraying the sodium hydroxide solution towards the center of the sample can precisely control the test area, ensuring that the reagent is evenly distributed on the surface of the sample, thereby obtaining more accurate test results; at the same time, the circular sample and the method of central spraying help to reduce the edge effect, ensuring that the sample is subjected to uniform chemical action, thereby improving the accuracy of the test.

[0056] In an embodiment of the present invention, the steps of clamping the intercepted sample and placing the sample horizontally include placing the surface of the sample facing upward and ensuring that the surface of the sample has no wrinkles. The absence of wrinkles on the sample surface can ensure uniform infiltration of the methyl orange reagent during testing, so that each position of the sample receives an equal amount of sodium hydroxide solution during spraying, avoiding deviation of test data caused by inconsistent thickness at each position due to wrinkles, thereby improving the accuracy of the test results. At the same time, the absence of wrinkles on the sample surface helps users observe the color change of the sample during the test.

[0057] In an embodiment of the present invention, the step of randomly selecting a product to be tested and intercepting a sample from the product to be tested further includes selecting a light-colored area as the area for intercepting the sample. When performing the waterproof performance test, the light-colored area is more conducive to observing the color change. The light-colored background can provide a higher contrast, making the color change more obvious and easier to detect. In an automated test system, the light-colored area is easier to be recognized and positioned by the machine, which helps to automate the application of the experimental test method for clothing fabrics.

[0058] The present invention also provides a clothing fabric experimental test system, which includes a memory, a processor, and a clothing fabric experimental test program stored on the memory and executable on the processor.
