Secondly, the test results can guide fabric production and processing technology to improve the breathability of fabrics.

[0003] However, in the prior art, when testing cloth, a part of the cloth can be cut off for testing, but this will cause a certain amount of cloth waste. When a longer cloth is used for testing, it will take a longer time for the operator to flatten the cloth, resulting in a longer time required for the operator to prepare work, thereby reducing work efficiency.

The operator tidies the other end of the cloth and controls the double-headed motor 904 to work at the same time, so that the output shafts on both sides of the double-headed motor 904 can drive the threaded rods 903 on both sides to rotate, so that the threaded rods 903 on both sides can drive the threaded blocks 905 on both sides to move synchronously, so that the threaded blocks 905 on both sides can move relatively, and the threaded rods 903 on both sides can drive the threaded rods 905 on both sides to move synchronously. Block 905 can drive multiple first support blocks 902 to move synchronously, so that the first support block 902 can drive one end of the four rotating rods 907 to move, so that the four rotating rods 907 drive the second support block 908 to expand to both sides, and the second support block 908 can drive the two arc plates 901 to expand, and at the same time control the first motor 11 to work, and the output shaft of the first motor 11 drives the frame 23 to rotate, so that the frame 23 can drive the arc plates 901 on both sides to rotate synchronously less than 90°. After that, the first motor 11 is stopped, and the cloth is rolled up to the middle part of the vertical plates 26 on both sides, so that the wrinkles of the cloth on the surface of the detection platform 12 can be stretched, so that the cloth can be spread flat on the upper surface of the detection platform 12, and at the same time, the cloth covers the second disc 14.

[0034] Compacting process: The external power supply of the control cylinder 205 is started, and the telescopic end of the cylinder 205 is shortened to drive the circular plate 206 to move, so that the circular plate 206 can drive the docking sleeve 204 to slide on the outer wall of the rotating shaft 208, so that the docking sleeve 204 can be sleeved on the outer wall of the docking rod 203 for clamping, and the second motor 201 is controlled to work, so that the output shaft of the second motor 201 rotates to drive the docking rod 203 to rotate, so that the docking rod 203 can drive the docking sleeve 204 to rotate synchronously, so that the docking sleeve 204 can drive the rotating shaft 208 to rotate, and the rotating shaft 208 can drive the bending block 209 to move synchronously, so that the bending block 209 can drive the pressing plate 7 to rotate with the rotating shaft 208 as the center, and the pressing plate 7 can drive the first circular plate 15 to move to a state of being close to the second disc 14, so that the rotating shaft 208 stops rotating, and the second motor 201 is stopped at the same time, and the first circular plate 15 and the second disc 14 can press the cloth.

[0035] Testing process: The fabric air permeability tester body 5 is controlled to work, and the fabric air permeability tester body 5 sucks air from the second disc 14 through a pipe, so that air can pass through the cloth and the first disc 15 and enter the fabric air permeability tester body 5. The fabric air permeability tester body 5 can display the test result through the display screen 4. After the test is completed, according to the above operation, the pressing plate 7 is returned to its original position, so that the pressing plate 7 is fitted with one side of the fabric air permeability tester body 5, and the docking rod 203 and the docking sleeve 204 are separated at the same time to prevent accidental injury to the operator due to compression caused by misoperation.

[0036] Fabric collection and sorting process: The first motor 11 is started to continue rotating, so that the cloth is completely rolled up to the outer wall of the frame 23 and the arc plates 901 on both sides, and the first motor 11 is stopped. The operator pulls the handrail 808 to move the vertical plate 801, so that the vertical plate 801 can slide on the outer wall of the straight rod 804 on both sides, and the vertical plate 801 can compress the spring 803, and the rotating disk 806 can be separated from the sliding rod 807. According to the above operation, the arc plates 901 on both sides are retracted inward, so that the cloth and the frame are rolled up. There may be a gap between the frame body 23. According to the above operation, the first clamping plate 25 and the second clamping plate 24 are separated so that the first clamping plate 25 and the second clamping plate 24 no longer clamp the cloth. The cloth can be drawn out through the gap between the frame body 23 and the vertical plate 801, which is convenient for the operator to collect. The armrest 808 is loosened so that the springs 803 on both sides are no longer compressed. Under the push of the springs 803 on both sides, the vertical plate 801 can be pushed to reset, so that the turntable 806 can be clamped with the slide rod 807 again.

[0037] Although the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
