Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0030] Please also read Figure 1 , Figure 2 and Figure 3 , a lint-shedding degree testing device 10 for pile fabrics provided in an embodiment of the present application is now described. The lint-shedding degree testing device 10 for pile fabrics includes a leveling base 100, a supporting assembly 200, a sample transfer box 300, an adsorption assembly 400, and a control module 500, wherein the supporting assembly 200 is fixedly arranged on the leveling base 100, the sample transfer box 300 is rotatably connected to the supporting assembly 200 for receiving and rolling fabric samples (not shown in the figure), thereby forming an impact effect on the fabric samples to simulate the complex stress conditions to which the fabric samples are subjected in actual wearing, the adsorption assembly 400 is used to absorb and collect the lint fibers dropped by the fabric samples during the rolling process (not shown in the figure), and the control module 500 is correspondingly used for: Get the quality of the fluff fibers; Get photos of the fuzz fibers; Performing grayscale processing on the photo to obtain a first image; Determine the amount and density of hair loss according to pixel distribution of the first image; The degree of linting is determined based on the initial mass of the fabric sample, the mass of the lint fibers, the amount of lint, and the lint density.
[0031] It should be noted that, in this embodiment, the control module 500 is a module with control capability and capable of data processing. Exemplarily, the control module 500 may be a central processing unit (CPU), a micro controller unit (MCU), or a module with equivalent functions.
[0032] It should be noted that, in the present embodiment, the initial mass of the above-mentioned fabric sample is the mass of the fabric sample before tumbling. The control module 500 can quantitatively reflect the weight loss of the pile fabric by obtaining the initial mass of the fabric sample and the mass of the fluff fibers. By obtaining photos of the fluff fibers, the morphology, distribution, quantity and other information of the fallen fluff fibers can be saved in the form of images, laying a data foundation for steps such as image processing and statistical analysis.
[0033] Furthermore, in this embodiment, the control module 500 can use MATLAB image processing software to perform grayscale processing on the photo to obtain a first image. Compared with the original multi-channel color photo, the first image obtained by grayscale processing only retains the single-channel brightness information, which can make the brightness difference between the fluff fiber and the background more intuitive, and then it can be easier to distinguish the fluff fiber from the background through threshold segmentation, edge detection and other methods, which is beneficial to subsequent image processing and provides a data basis for statistical hair loss quantity, hair loss density, etc.
[0034] Furthermore, in this embodiment, the control module 500 may determine the amount and density of hair loss according to the pixel distribution of the first image, including: performing histogram equalization processing on the first image to enhance the contrast of the first image to obtain a second image; performing brightness enhancement processing on the second image to obtain a third image; performing binary conversion processing on the third image to obtain a fourth image; performing expansion processing on the fourth image to obtain a fifth image; performing denoising processing on the fifth image to obtain a sixth image; and counting the number of fluff fibers in the sixth image to determine the amount of hair loss.
[0035] Furthermore, in this embodiment, the control module 500 may perform brightness enhancement processing on the second image by using an addition operation to perform numerical addition operations of the same magnitude on each pixel of the second image, thereby improving the overall brightness of the second image to facilitate subsequent observation or analysis.
[0036] Furthermore, in this embodiment, the control module 500 may perform binary conversion processing on the third image, including: comparing the gray value of each pixel in the third image with a threshold value, determining pixels with gray values greater than the threshold value as 1 (foreground pixels), and determining pixels with gray values less than or equal to the threshold value as 0 (background pixels), thereby obtaining a binary image matrix (fourth image) composed of 0 and 1. In order to facilitate the rapid positioning of the fluff fibers and improve the recognition of the fluff fibers, the fluff fibers (foreground pixels) may be represented by white (1) and the background by black (0). If the control module 500 performs binary conversion processing on the third image, the fluff fibers (foreground pixels) are represented by black (0) and the background is represented by white (1), and the third image may be inverted, thereby improving the recognition of the fluff fibers.
[0037] Furthermore, in this embodiment, the control module 500 may perform expansion processing on the fourth image, which may include: widening the boundary of the foreground (fuzzy fibers) outward by one pixel or more pixels in the fourth image, filling the holes or breaks in the foreground (fuzzy fibers), thereby increasing the brightness of the foreground pixels (fuzzy fibers); specifically, a kernel function may be used to scan each pixel position in the fourth image. When the center of the kernel function is aligned with a pixel in the fourth image, if a foreground pixel (1) in the kernel function overlaps with the scanned area, the corresponding center pixel will be assigned the foreground pixel (1).
[0038] Furthermore, in this embodiment, the control module 500 may perform denoising on the fifth image, including: processing the fifth image with a 3*3 median filter to remove high-frequency noise in the fifth image, while retaining the fiber edges and morphological features, weakening single pixel points such as "isolated bright spots" or "black spots" whose brightness or grayscale values are obviously too high or too low, thereby reducing interference with subsequent identification and counting, and thereby improving the accuracy of subsequent villi fiber statistics.
[0039] Furthermore, in this embodiment, the control module 500 determines the amount and density of hair loss according to the pixel distribution of the first image and may also include: calculating the area of the foreground pixels in the fourth image; determining the hair loss density according to the area of the foreground pixels and the preset pixel area; specifically, the control module 500 can use the bwarea function to estimate the area of the foreground pixels (fiber fluff) in the fourth image, and then obtain the foreground proportion according to the area of the foreground pixels and the preset pixel area, and determine the foreground proportion as the hair loss density.
[0040] For example, if a high-definition camera with a maximum resolution of 10,000 × 10,000 pixels is used to take a picture of the fluff fibers, the preset pixel area is 1 × 10 8 pixels, the area of the foreground pixel in the fourth image is calculated to be 1×10 6 In the case of , the foreground ratio can be obtained as 1% according to the first formula, and the foreground ratio is determined as the hair loss density. This means that in the fourth image, some pixels are detected as fluff fibers (foreground), and the remaining 99% of the pixels are background.
[0041] (1); in, A represents the area of the foreground pixel, A 1 indicates the preset pixel area.
[0042] Furthermore, in the present embodiment, the control module 500 may determine the degree of lint according to the initial quality of the fabric sample, the quality of the lint fibers, the amount of lint and the density of lint, including: determining the lint quality grade according to the initial quality of the fabric sample and the quality of the lint fibers; determining the lint quantity grade according to the amount of lint; determining the lint density grade according to the lint density; determining the degree of lint according to the lint quality grade, the lint quantity grade and the lint density grade.
[0043] Furthermore, in this embodiment, the control module 500 determines the lint quality level according to the initial mass of the fabric sample and the mass of the lint fibers, which may include: calculating the fabric mass loss rate according to the initial mass of the fabric sample, the mass of the lint fibers and the second formula, and determining the lint quality level according to the fabric mass loss rate.
[0044] (2); Where m represents the mass of the fluff fiber and m1 represents the initial mass of the fabric sample.
[0045] The corresponding relationship between fabric mass loss rate and hair loss quality grade is shown in Table 1.
[0046] Table 1
[0047] It should be noted that the corresponding relationship between the fabric mass loss rate and the hair loss quality grade can be adjusted according to the actual application, and Table 1 is only an example.
[0048] The corresponding relationship between the amount of hair loss and the level of hair loss is shown in Table 2.
[0049] Table 2
[0050] It should be noted that the correspondence between the amount of hair loss and the level of hair loss can be adjusted according to actual applications, and Table 2 is only an example.
[0051] The corresponding relationship between hair loss density and hair loss density level is shown in Table 3.
[0052] Table 3
[0053] It should be noted that the correspondence between the hair loss density and the hair loss density level can be adjusted according to actual applications, and Table 3 is only an example.
[0054] Further, in the present embodiment, the control module 500 may determine the degree of hair loss according to the hair loss quality level, the hair loss quantity level and the hair loss density level, and may include: taking the average of the worst two levels among the hair loss quality level, the hair loss quantity level and the hair loss density level as the hair loss level, and rounding the average when the average is not an integer. By taking the average of the two worst indicators, it is possible to more truly reflect the deficiencies of the product in the weakest part of the hair loss performance, and avoid one indicator masking the possible hair loss problems of the other two indicators.
[0055] The beneficial effect of the lint degree testing device 10 for pile fabrics provided in the present application is that, compared with the prior art, the lint degree testing device 10 for pile fabrics realizes tumbling and collision processing of fabric samples by rotating the sample transfer box 300, and can better simulate the complex stress conditions to which fabric samples are subjected during actual use and wearing. On this basis, the adsorption component 400 adsorbs and collects the fluff fibers dropped by the fabric sample during the tumbling process, and the control module 500 obtains the initial mass of the fabric sample, the mass of the fluff fibers and photos of the fluff fibers, which can quantitatively reflect the weight loss of the fabric sample, as well as the distribution, quantity and density of the fluff fibers, and then can comprehensively determine the lint degree of the pile fabric based on the mass of the fluff fibers, the amount of lint and the lint density, thereby overcoming the problem that the traditional testing method has a single evaluation indicator and relies on the subjective judgment of the tester, and effectively improves the reliability and accuracy of the test results.
[0056] It should be noted that before conducting the test, one or more fabric samples of appropriate size need to be cut from the pile fabric sample. The fabric samples are square or circular in structure, and the peripheral sides of the fabric samples are sealed based on standard requirements to prevent the peripheral sides of the fabric samples from being worn or falling apart during the tumbling process, and to prevent the fluff fibers from falling from the peripheral sides of the fabric samples, which may ultimately affect the test results.

A fixing groove 311 and a switch door 312 are respectively provided on opposite sides of the rotating box body 310. The fixing groove 311 is located on the outer side of the rotating box body 310. The first electrostatic suction cup 410 is embedded in the fixing groove 311 and forms an electrostatic adsorption area 313 on the inner side of the corresponding position of the rotating box body 310, that is, the electrostatic adsorption area 313 is located on the inner side of the rotating box body 310 and faces the first electrostatic suction cup 410.
