Description
Technical Field
[0001] The invention relates to the technical field of fabric wear resistance testing, in particular to an efficient Martindale wear resistance testing machine. Background Art
[0002] The Martindale Abrasion Test is a standardized test method used to test the resistance of fabrics to friction under a certain pressure. The test requirements of this method include specific loads and test times, which are designed to simulate the friction conditions experienced by fabrics in daily use, so as to evaluate the durability and quality of fabrics.
[0003] The traditional test steps are as follows:
[0004] Cut a piece of sample from the flat part of the specimen;
[0005] Remove the load and load shaft from the testing machine;
[0006] Remove the top plate and test fixture;
[0007] Place the sample into the test fixture base and place a sample gasket, such as a foam pad, between the sample and the test fixture base;
[0008] Place the wool felt and friction cloth on the base, and press a pressure plate of specified weight on the friction cloth;
[0009] Pass the load shaft through the round hole on the top plate;
[0010] Place the test fixture with the specimen facing downward on the base fixture, and adjust the circular groove of the test fixture to align with the load shaft;
[0011] Turn on the switch to start the test;
[0012] After reaching the set number of times, the machine will automatically stop and the sample will be removed to determine the result.
[0013] Usually, multiple samples of a fabric are subjected to wear resistance test at the same time to improve the rationality and accuracy of fabric evaluation. However, one existing device can only test one fabric. After the test is completed, the machine needs to be stopped to remove the sample and then replace the friction cloth before the next fabric can be tested. If multiple fabrics are subjected to wear resistance test at the same time, the test efficiency of the wear resistance test is low, so it is necessary to improve it. Summary of the invention
[0014] The purpose of the present invention is to provide an efficient Martindale wear tester in view of the deficiencies in the prior art. A turntable mechanism is rotated to drive a group of test modules to stop at a loading and unloading station. At the loading and unloading station, a sample of a fabric is fixed by a sample clamp, a friction cloth is fixed by the friction cloth clamp, and a counterweight device adjusts the load of the sample clamp. Then, the turntable mechanism rotates to drive the group of loaded test modules to remain at the operating station. In this way, samples of multiple fabrics are loaded on multiple groups of test modules and rotated to the operating station.
[0015] All the test modules at the operating station are driven by their respective drivers to carry out wear resistance tests on the samples of their respective multiple sample fixtures and the friction cloth of the corresponding friction cloth fixture in the order in which they enter the operating station. When the wear resistance test of the test module is completed, the turntable mechanism rotates to drive the test module that has completed the wear resistance test to stop at the loading and unloading station again, so as to facilitate the removal of the sample that has completed the wear resistance test, the replacement of the friction cloth and the fixation of the sample of another fabric in the sample fixture again, without affecting the work of the test module carrying out the wear resistance test at the operating station, thereby improving the test efficiency of carrying out wear resistance tests on multiple samples of various fabrics at the same time.
[0016] To achieve the above-mentioned purpose, the present invention provides an efficient Martindale wear tester, comprising a machine platform, a turntable mechanism arranged on the machine platform, an evaluation platform and a main control module.
[0017] The turntable mechanism is provided with multiple test modules, each of which includes a counterweight device, a weighing module, a driver, multiple friction cloth fixtures and multiple sample fixtures;
[0018] The machine is equipped with loading and unloading stations, operation stations and evaluation stations;
[0019] The turntable mechanism is rotatably arranged between the loading and unloading stations and the operation stations, and multiple groups of test modules are arranged at intervals on the turntable mechanism;
[0020] The weight counterweight device is arranged on the turntable mechanism to adjust the load of the sample fixture;
[0021] The weighing module is used to sense the load of the test material fixture;
[0022] The friction cloth clamp is used to fix the friction cloth and the felt;
[0023] The sample fixture is used to fix the sample and the foam pad, and the sample fixture and the driver are set to slide up and down;
[0024] The driver is used to drive the sample fixture and the friction cloth fixture to perform the wear test;
[0025] The evaluation platform is fixed to the evaluation station and is used to carry the sample. The evaluation platform is provided with a first camera and a second camera;
[0026] The first camera and the second sensor are both used to obtain an image of the sample;
[0027] The main control module is electrically connected to the turntable mechanism, the counterweight device, the weighing module, the driver, the first camera and the second camera respectively;
[0028] The Martindale wear tester also includes wear tests and evaluation methods:
[0029] A. The sample is placed on the evaluation platform. The first camera and the second camera respectively obtain images of the sample and feed them back to the main control module. The main control module records the initial image of the sample. The initial image of the sample is compared with the preset fabric type library to determine the fabric type of the sample.
[0030] B. The turntable mechanism rotates to drive a group of test modules to stop at the loading and unloading station, where the friction cloth and felt are fixed to the friction cloth fixture of the group of test modules, and the sample and foam pad are fixed to the sample fixture of the group of test modules to complete the loading operation of a group of test modules;
[0031] C. The main control module adjusts the load of the sample fixture through the weight-balancing device according to the sample fabric type, and the weighing module feeds back the load value to the main control module;
[0032] D. After the load value matches the preset load, the main control module controls the turntable mechanism to rotate so that the loaded test module remains in the working station. This is repeated to load samples of various fabrics into multiple groups of test modules and rotate them to the working station. All test modules in the working station are driven by their respective drivers to perform wear tests on the samples of their respective sample fixtures and the friction cloth of the corresponding friction cloth fixture in the order of entering the working station.
[0033] E. When the wear test of a group of test modules reaches the preset time, the main control module controls the turntable mechanism to rotate, so that the test module that has completed the wear test stops again at the loading and unloading station, and then replaces the friction cloth in the friction cloth fixture of the test module, replaces the sample in the sample fixture, and places the sample that has completed the wear test on the evaluation table;
[0034] F. The first camera and the second camera respectively obtain images of the sample and feed them back to the main control module. The image of the sample is evaluated for wear resistance performance against the preset evaluation standard.
[0035] The beneficial effects of the present invention are as follows: a group of test modules are driven to stop at the loading and unloading station by the rotation of the turntable mechanism, and after a sample of a fabric material is fixed by a sample clamp, a friction cloth is fixed by the friction cloth clamp, and the load of the sample clamp is adjusted by a counterweight device at the loading and unloading station, the turntable mechanism rotates to drive the group of loaded test modules to remain at the operating station, so that samples of multiple fabric materials are loaded on multiple groups of test modules and rotated to the operating station.
[0036] All the test modules at the operating station are driven by their respective drivers to carry out wear resistance tests on the samples of their respective multiple sample fixtures and the friction cloth of the corresponding friction cloth fixture in the order in which they enter the operating station. When the wear resistance test of the test module is completed, the turntable mechanism rotates to drive the test module that has completed the wear resistance test to stop at the loading and unloading station again, so as to facilitate the removal of the sample that has completed the wear resistance test, the replacement of the friction cloth and the fixation of the sample of another fabric in the sample fixture again, without affecting the work of the test module carrying out the wear resistance test at the operating station, thereby improving the test efficiency of carrying out wear resistance tests on multiple samples of various fabrics at the same time.

DETAILED DESCRIPTION
[0046] The present invention is described in detail below with reference to the accompanying drawings.
[0047] like Figures 1 to 7 As shown, an efficient Martindale wear tester of the present invention comprises a machine platform 1, a turntable mechanism 2 arranged on the machine platform 1, an evaluation platform 3 and a main control module.
[0048] The turntable mechanism 2 is provided with a plurality of test modules 4, each of which includes a counterweight device 5, a weighing module, a driver 6, a plurality of friction cloth fixtures 7 and a plurality of sample fixtures 8. Specifically, the plurality of test modules 4 are distributed in the turntable mechanism 2 in a circular array with the center of the turntable mechanism 2 as the center of the circle.
[0049] The machine 1 is provided with a loading and unloading station 11, an operation station 12 and an evaluation station 13. Specifically, the loading and unloading station 11 is provided on one side of the machine 1 close to the evaluation station 3. In this way, the test sample that has completed the test can be moved to the evaluation station 3 more quickly.
[0050] The turntable mechanism 2 is rotatably disposed between the loading and unloading station 11 and the operation station 12 , and a plurality of test modules 4 are disposed at intervals on the turntable mechanism 2 .
[0051] The weight device 5 is provided on the turntable mechanism 2 to adjust the load of the sample holder 8 .
[0052] The weighing module is used to sense the load of the test sample fixture 8 .
[0053] The friction cloth fixture 7 is used to fix the friction cloth and the felt.
[0054] The sample fixture 8 is used to fix the sample and the foam pad, and the sample fixture 8 and the driver 6 are slidably arranged up and down.
[0055] The driver 6 is used to drive the sample fixture 8 and the friction cloth fixture 7 to perform the wear test.
[0056] The evaluation platform 3 is fixed to the evaluation station 13 and is used to carry the sample. The evaluation platform 3 is provided with a first camera 31 and a second camera 32 .
[0057] The first camera 31 and the second sensor are both used to obtain images of the sample.
[0058] The main control module is electrically connected to the turntable mechanism 2, the counterweight device 5, the weighing module, the driver 6, the first camera 31 and the second camera 32, respectively, so that the main control module can control the turntable mechanism 2, the counterweight device 5, the weighing module, the driver 6, the first camera 31 and the second camera 32 or receive feedback information.
[0059] When in use, the turntable mechanism 2 rotates and drives a group of test modules 4 to stop at the loading and unloading station 11. At the loading and unloading station 11, a sample of a fabric material is fixed by a sample clamp 8, a friction cloth is fixed by a friction cloth clamp 7, and the load of the sample clamp 8 is adjusted by the counterweight device 5. Then, the turntable mechanism 2 rotates and drives the group of loaded test modules 4 to remain at the operating station 12. In this way, samples of multiple fabric materials are loaded to multiple groups of test modules in sequence, and then rotated to the operating stations in sequence.
[0060] All the test modules 4 at the workstation 12 are driven by their respective drivers 6 in the order of entering the workstation 12 to perform wear resistance tests on the samples of their respective sample holders 8 and the friction cloth of the corresponding friction cloth holder 7 .
[0061] When the wear test is completed, the turntable mechanism 2 rotates and drives the test module 4 that has completed the wear test to stop at the loading and unloading station 11 in sequence, which is convenient for taking out the sample that has completed the wear test, replacing the friction cloth, and fixing the sample of another fabric material in the sample fixture 8 again, without affecting the work of the test module 4 performing the wear test at the operating station 12, thereby improving the test efficiency of performing wear tests on multiple samples of multiple fabric materials at the same time.
[0062] The Martindale wear tester of the present invention also includes a wear test and evaluation method:
[0063] A. The sample is placed on the evaluation table 3. The first camera 31 and the second camera 32 respectively obtain images of the sample and feed them back to the main control module. The main control module records the initial image of the sample. The initial image of the sample is compared with the preset fabric type library to determine the fabric type of the sample.
[0064] B. The turntable mechanism 2 rotates to drive a group of test modules 4 to stop at the loading and unloading station 11, where the friction cloth and felt are fixed to the friction cloth fixture 7 of the group of test modules 4, and the sample and foam pad are fixed to the sample fixture 8 of the group of test modules 4 to complete the loading operation of a group of test modules 4.
[0065] C. The main control module adjusts the load of the sample fixture 8 through the weight-balancing device 5 according to the sample fabric type, and the weighing module feeds back the load value to the main control module.
[0066] D. After the load value matches the preset load, the main control module controls the turntable mechanism 2 to rotate so that the loaded test module 4 remains in the working station 12. This is repeated to complete the loading of samples of various fabrics into multiple groups of test modules and rotate them to the working station. All test modules 4 in the working station 12 are driven by their respective drivers 6 in the order of entering the working station 12 to perform wear resistance tests on the samples of their respective multiple sample fixtures 8 and the friction cloth of the corresponding friction cloth fixture 7.
[0067] E. When the wear test of a group of test modules 4 reaches the preset time, the main control module controls the turntable mechanism 2 to rotate so that the test module 4 that has completed the wear test stops again at the loading and unloading station 11, replaces the friction cloth in the friction cloth fixture 7 of the test module 4, replaces the sample in the sample fixture 8, and places the sample that has completed the wear test on the evaluation table 3.
[0068] F. The first camera 31 and the second camera 32 respectively obtain images of the sample and feed them back to the main control module, and the image of the sample is evaluated for wear resistance performance according to the preset evaluation standard. The present invention allows multiple samples of multiple fabrics to undergo wear resistance tests at the same time, improves the test efficiency of the wear resistance test, and intelligently evaluates the wear resistance performance of the samples that have completed the wear resistance test.
[0069] like Figure 3 and Figure 6 As shown, the friction cloth fixture 7 of this embodiment includes a fixing box 71, an insert 72 and a first actuator 73. The first actuator 73 is a thin cylinder or a micro electric screw.
[0070] The first actuator 73 is electrically connected to the main control module, so that the main control module can control the operation of the first actuator 73. The fixing box 71 is fixed to the turntable mechanism 2, and a slot 711 is provided inside the fixing box 71. A first opening 712 for inserting the insert 72 into the slot 711 is provided on the side of the slot 711, and a second opening 713 for exposing the friction cloth is provided on the top of the slot 711.
[0071] Buckles 721 for fixing the friction cloth are respectively provided at both ends of the insert 72 , and the friction cloth is movably fixed to the insert 72 through the buckles 721 .
[0072] The first actuator 73 penetrates through the slot 711 of the fixing box 71 and contacts the inserting member 72 , so that the inserting member 72 is pressed against the inner wall of the slot 711 , thereby fixing the friction cloth to the friction cloth fixture 7 .
[0073] The inner wall of the slot 711 of this embodiment is respectively provided with a first scraper 714, a second scraper 715, a third scraper 716 and a fourth scraper 717, which are all elastic scrapers, such as strip structures made of silicone.
[0074] The first scraper 714, the second scraper 715, the third scraper 716 and the fourth scraper 717 form a four-sided trapezoidal structure and are arranged at the periphery of the second opening 713. The second scraper 715 and the fourth scraper 717 are inclined along the direction in which the insert 72 is inserted into the slot 711. The length of the first scraper 714 is shorter than that of the third scraper 716, so that the second scraper 715 and the fourth scraper 717 are trumpet-shaped.
[0075] When the friction cloth and the felt are inserted into the slot 711 from the first opening 712 along with the insert 72, the friction cloth first rubs against the first scraper 714, and the friction cloth is flattened by the friction of the first scraper 714. The friction cloth then rubs against the second scraper 715 and the fourth scraper 717, so that the friction cloth is spread out to both sides of the second scraper 715 and the fourth scraper 717 respectively. The friction cloth finally contacts the third scraper 716, thereby increasing the friction force between the friction cloth and the felt, so that the friction cloth and the felt are not easily displaced.
[0076] One end of the insert 72 facing the second opening 713 is provided with a roughened surface 722 for increasing the friction between the insert 72 and the felt. The roughened surface 722 increases the friction between the insert 72 and the felt, making it difficult for the insert 72 and the felt to move.
[0077] Method for fixing the friction cloth and the felt to the friction cloth fixture 7:
[0078] B11. The felt is placed on the roughened surface 722 of the insert 72 , and the friction cloth planted in long strips is stacked on top of the felt. The stacked friction cloth and the felt are clamped at the same end of the insert 72 by the buckle 721 .
[0079] B12. The insert 72 is inserted into the slot 711 through the first opening 712. The friction cloth is fixed to one end of the insert 72 and enters the slot 711 together with the insert 72. During the insertion process, the friction cloth rubs against the first scraper bar 714 so that the friction cloth and the felt are smoothed. The friction cloth rubs against the second scraper bar 715 and the fourth scraper bar 717 so that the friction cloth and the felt are spread out to both sides. After the insert 72 is completely inserted into the slot 711, the friction cloth contacts the third scraper bar 716 to increase the friction between the friction cloth and the felt.
[0080] B13. Engage the buckle 721 at the other end of the insert 72 to fix the friction cloth and the felt to the insert 72 .
[0081] Preferably, the second opening 713 is circumferentially provided with a guard 74, the guard 74 is provided with a plurality of through holes 741, a vacuum cleaner is provided on the outside of the guard 74, the vacuum cleaner is electrically connected to the main control module, and the vacuum cleaner is connected to the inside of the guard 74 through the through holes 741. When the friction cloth in the second opening 713 and the sample are subjected to a wear resistance test, the fiber fragments are broken due to fatigue damage due to friction, or the fibers are pulled out of the fabric and fall off to produce fiber filaments. The vacuum cleaner collects the fiber filaments in the vacuum cleaner through the through holes 741 through negative pressure. On the one hand, the number of fiber filaments can be used as a reference factor for evaluation when evaluating the wear resistance performance. On the other hand, the negative pressure generated by the vacuum cleaner causes air to flow around the sample and the friction cloth, which is beneficial to the temperature reduction of the sample and the friction cloth, thereby achieving temperature control of the sample and the friction cloth.
[0082] like Figure 3 and Figure 7 As shown, the sample fixture 8 of this embodiment includes a fixing frame 81, a second actuator 82 and a pressing member 83. The second actuator 82 is a cylinder or an electric screw.
[0083] The second actuator 82 is electrically connected to the main control module. A fixed cavity 811 is provided at one end of the fixed frame 81. The fixed cavity 811 is provided with a first hole 812 for taking and placing the sample and a second hole 813 for exposing the sample. The first hole 812 is arranged through the side of the fixed cavity 811, and the second hole 813 is connected to the fixed cavity 811 and passes through the bottom of the fixed frame 81.
[0084] The second actuator 82 is used to drive the holding member 83 to slide along the fixed cavity 811 to approach or move away from the second hole 813 of the fixed cavity 811. Specifically, the foam pad and the sample are placed in the fixed cavity 811, with the sample facing one end of the second hole 813. The second actuator 82 drives the holding member 83 to slide along the fixed cavity 811 to approach the second hole 813, so that the foam pad and the sample are pushed to the inner wall of the second hole 813. When the holding member 83 pushes the foam pad and the sample to collide with the inner wall of the second hole 813 of the fixed cavity 811, the foam pad and the sample are fixed to the inner wall of the second hole 813 of the fixed cavity 811. When the second actuator 82 drives the holding member 83 to slide along the fixed cavity 811 and move away from the second hole 813 of the fixed cavity 811, it is convenient to take the foam pad and the sample out of the fixed cavity 811.
[0085] In this embodiment, a flexible boss is disposed at the end of the pressing member 83 , and the pressing member 83 contacts the inner wall of the second hole 813 , and the flexible boss is exposed outside the second hole 813 .
[0086] The method of fixing the sample and the foam pad to the sample fixture 8 is as follows:
[0087] B21. The foam pad is stacked on the sample, and the stacked sample and the foam pad are placed in the fixed cavity 811 through the first hole 812. The second actuator 82 drives the holding member 83 to slide along the fixed cavity 811 and approach the second hole 813, so that the stacked sample and the foam pad are pressed against the inner wall of the second hole 813.
[0088] B22. The pressing piece 83 contacts the inner wall of the second hole 813 so that the sample and the foam pad contact the inner wall of the second hole 813, and the flexible boss lifts the foam pad and the sample so that the sample is exposed outside the second hole 813, thereby fixing the sample and the foam pad to the sample fixture 8, and the sample is exposed outside the second hole 813.
[0089] like Figure 4 and Figure 7 As shown, the fixed frame 81 of this embodiment is also provided with a counterweight cavity 814, the counterweight cavity 814 is provided with a conveying port 815 connected to the outside, and the counterweight cavity 814 is provided with a first avoidance groove 816, which extends along the height direction of the counterweight cavity 814 and is connected to the conveying port 815.
[0090] The counterweight device 5 includes a counterweight bin 51, a counterweight block 52, a third actuator 53, and a carrying and conveying member 54, wherein the third actuator 53 is a lifting and rotating manipulator. The third actuator 53 and the carrying and conveying member 54 are both electrically connected to the main control module, so that the main control module can control the third actuator 53 and the carrying and conveying member 54.
[0091] The counterweight bin 51 is fixed to the turntable mechanism 2 and is used to fix the counterweight block 52 . The third actuator 53 drives the carrying conveyor 54 to convey the counterweight block 52 to move between the counterweight bin 51 and the counterweight cavity 814 .
[0092] The counterweight bin 51 is provided with a take-in / take-out port 511 communicating with the outside, and the counterweight bin 51 is provided with a second avoidance groove 512 , which extends along the height direction of the counterweight bin 51 and communicates with the take-in / take-out port 511 .
[0093] The counterweight block 52 is stacked in the counterweight bin 51 or the counterweight cavity 814 . The counterweight block 52 is provided with a fixing groove for transporting the counterweight block 52 itself, and the fixing groove of the counterweight block 52 is exposed in the first avoidance groove 816 and the second avoidance groove 512 , respectively.
[0094] Specifically, the counterweight cavity 814 and the counterweight bin 51 are both provided with limit bars, and the counterweight block 52 is provided with a limit slot that cooperates with the limit bar, and the limit bar cooperates with the limit slot, so that the counterweight block 52 is limited and stacked in the counterweight bin 51 or the counterweight cavity 814, and is not easy to rotate. The fixing slots of the counterweight block 52 are exposed in the first avoidance slot 816 and the second avoidance slot 512, respectively.
[0095] The carrying and conveying member 54 includes a fixing plate 541 , a visual sensing module 542 , a fourth actuator 543 and a telescopic member 544 . The fourth actuator 543 is a linear driver 6 , such as a linear cylinder, an electric push rod, etc.
[0096] The telescopic member 544 is slidably connected to the fixed plate 541. The fourth actuator 543 is fixed to the fixed plate 541 and is used to drive the telescopic member 544 to extend or retract. The visual sensing module 542 is fixed to the fixed plate 541 and is used to sense the fixing groove of the counterweight 52. The visual sensing module 542 and the fourth actuator 543 are both electrically connected to the main control module.
[0097] The main control module of this embodiment adjusts the load of the sample fixture 8 through the weight balancing device 5 according to the type of sample fabric, specifically including:
[0098] C1. The main control module controls the third actuator 53 to drive the carrying conveyor 54 to rotate R1 angle and approach the counterweight bin 51, so that the telescopic member 544 is aligned with the second avoidance groove 512.

[0107] like Figure 1 As shown, brackets 33 are provided on both sides of the evaluation platform 3 of this embodiment, and the first camera 31 and the second camera 32 are respectively provided on the brackets 33 .
[0108] The first camera 31 is a high-definition camera, and the second camera 32 is an infrared camera.
[0109] The method for the first camera 31 and the second camera 32 to respectively acquire images of the sample is as follows:
[0110] G1. Obtain a high-definition picture of the sample through the first camera 31 and execute G2.
[0111] G2. Let the sample stand for 2-3 minutes and measure the temperature of the sample. If the sample temperature is within the preset temperature range, execute step G3. Otherwise, wait for 2 minutes and measure the temperature of the sample again to achieve temperature control of the sample.
[0112] G3. When the sample temperature is within the preset temperature range, an infrared image of the sample is acquired through the second camera 32. The image of the sample is acquired at a specific temperature to improve the image clarity of the sample.
[0113] The preset temperature range is between 10°C and 40°C, and this embodiment takes the preset temperature of 20°C to 25°C as an example.
[0114] like Figure 2 As shown, the evaluation platform 3 of this embodiment is provided with a protective cover 34, an air blowing device and an air suction device.
[0115] A concave cavity 35 is provided in the evaluation platform 3, and a protective cover 34 is hinged to the machine platform 1 and covers the top of the concave cavity 35. A plurality of first air holes 351, a plurality of second air holes 352, a plurality of third air holes 353 and a plurality of fourth air holes 354 are provided through the concave cavity 35.

Both the blowing device and the suction device are electrically connected to the main control module.
[0116] The blowing device blows air into the concave cavity 35 through the plurality of first air holes 351 and the plurality of second air holes 352 , and the suction device sucks air into the concave cavity 35 through the plurality of third air holes 353 and the plurality of fourth air holes 354 .
[0117] Before the first camera 31 and the second camera 32 respectively acquire images of the sample, the sample needs to be cleaned by air showering. The specific steps are as follows:
[0118] F1. Lift the protective cover 34, place the sample in the concave cavity 35 of the evaluation table 3, and cover the protective cover 34 to prevent the fibers blown out of the sample from adhering to the lenses of the first camera 31 and the second camera 32 during air shower cleaning, so as to avoid affecting the operation of the first camera 31 and the second camera 32.
[0119] F2. The suction device sucks air into the sample through the plurality of third air holes 353 so that the sample is fixed in the cavity 35 by negative pressure.
[0120] F3. The air blowing device blows air into the concave cavity 35 through the multiple first air holes 351, so that the sample is partially arched and separated from the concave cavity 35, and the positive pressure air passes through the gaps between the fibers of the sample to blow out the fiber filaments generated by friction, so that the sample is clean.
[0121] Specifically, the blowing device intermittently blows air into the concave cavity 35 through multiple first air holes 351, such as blowing for 2 seconds and stopping for 1 second, so that the part of the sample that is arched and separated from the concave cavity 35 is fixed to the concave cavity 35 again by negative pressure, so that the sample is deformed and the fiber filaments are easier to blow out from the gaps between the fibers.
[0122] F4. The suction device sucks air into the concave cavity 35 through the plurality of fourth air holes 354, so that the blown-out fiber filaments are sucked away through the fourth air holes 354, and the fiber filaments are collected.
[0123] F5. The blowing device intermittently blows air into the concave cavity 35 through the plurality of second air holes 352 to speed up the floating speed of the fiber filaments in the protective cover 34 , making it easier for the fiber filaments to be sucked away through the fourth air holes 354 .
[0124] Specifically, after the blowing device blows air into the concave cavity 35 through the multiple second air holes 352 for 2-3 seconds, the blowing device stops working and works again after waiting for 3 to 5 seconds, thereby achieving intermittent blowing of air into the concave cavity 35 through the multiple second air holes 352 .
[0125] F6. After the preset time is reached, the blowing device stops, the suction device stops sucking air through the plurality of fourth air holes 354, the protective cover 34 is lifted, the air shower cleaning is completed, and the sample is clean.
[0126] Specifically, during the wear resistance evaluation of the sample image and the preset evaluation standard, the sample test qualification index W is judged by the formula W=Wt×Ts×(Eh×Et×Ec). When 0.2≤W≤1.0, it is considered qualified, and W<0.2 is considered unqualified.
[0127] Wt represents the wear degree score, which can be determined based on the wear features identified by the main control module, such as wear, yarn breakage, pilling, etc. Specifically, after the sample image is preprocessed, the sample image is input into the trained evaluation standard model, and the evaluation standard model automatically extracts features related to wear resistance from the image, such as the size, shape, and color of the wear area. The extracted features are compared with the evaluation standard model, and the wear amount is obtained by comparing the initial sample image with the sample image, such as the number of worn areas P1, the number of broken yarns P2, the number of pilling P3, and the number of pilling P4.
[0128] Among them, the weight Q1 of the number of worn areas P1 ranges from 0.1 to 0.3.
[0129] The weight Q2 of the number of broken yarns P2 ranges from 0.1 to 0.3.
[0130] The weight Q3 of the fuzz quantity P3 ranges from 0.1 to 0.2.
[0131] The weight Q4 of the pilling quantity P4 ranges from 0.1 to 0.2.
[0132] The formula for the wear degree score Wt is: Wt={(P1*Q1)+(P2*Q2)+(P3*Q3)+(P4*Q4)} / 10, thereby obtaining the wear degree score of the sample.
[0133] Ts represents the wear resistance coefficient of the fabric, which is obtained based on the experimental data of similar materials and industry standards. It is a parameter that reflects the wear resistance of the fabric material itself. Different fabric materials, such as cotton, polyester, nylon, etc., have different wear resistance.
[0134] The range of Ts is usually set according to the type and material of the fabric and can be any positive number.
[0135] Environmental factor coefficient, taking into account other influences that the fabric may be subjected to in the use environment, such as humidity, temperature, chemical contact, etc. This coefficient can be adjusted to reflect the impact of these external factors on wear resistance.
[0136] Eh is the humidity influence coefficient, the range of Eh is from 0 to 1.
[0137] 0 means humidity has no effect on wear resistance.
[0138] 1 means humidity has the greatest impact on wear resistance.
[0139] Et is the temperature influence coefficient, and the range of Et is 0 to 1.
[0140] 0 means that temperature has no effect on wear resistance.
[0141] 1 means that temperature has the greatest impact on wear resistance.
[0142] Both high and low temperatures can have a negative impact on the wear properties of a fabric, the extent of which depends on the fabric's material and construction.
[0143] Ec is the chemical exposure impact coefficient, and the range of Ec is 0 to 1.
[0144] 0 means that the chemical has no effect on the wear resistance.
[0145] 1 means the chemical has the greatest impact on wear resistance,
[0146] Different chemicals may have different degrees of impact on the wear resistance of fabrics, and the specific degree of impact depends on factors such as the type, concentration and contact time of the chemical.
[0147] For example, the number of frays is 5, the number of yarn breaks is 3, the number of fuzz is 8, and the number of pilling is 4.
[0148] The weight Q1 of the number of worn areas P1 is 0.1, the weight Q2 of the number of broken yarns P2 is 0.1, the weight Q3 of the number of fuzzing P3 is 0.1, and the weight Q4 of the number of pilling P4 is 0.1. The wear degree score Wt of the sample is calculated by the formula Wt={(P1*Q1)+(P2*Q2)+(P3*Q3)+(P4*Q4)} / 10, thereby obtaining a wear degree score Wt of 0.2.
[0149] Substitute the wear degree score Wt of the sample as 0.2 into the formula W = Wt × Ts × (Eh × Et × Ec), and take Ts as 10, Eh as 0.7, Et as 0.9, and Ec as 0.5 as an example to calculate the qualified index W of the sample test, and obtain W as 0.63, which represents each grid of the sample test.

The content of this specification should not be understood as limiting the present invention.
