Analysis of the operation method of the fabric air permeability meter
The fabric air permeability tester is used to test the air permeability of non-woven fabrics, meltblown fabrics, special industrial fabrics, general fabrics, sponges, knitted fabrics, coated fabrics, non-woven fabrics and industrial filter paper. Applicable standards: GB/T5453, ISO9237, AFNORG07-111, ASTM737, BS5636, JISL1096-A, DIN53887 Test principle: According to the specified method and test parameters, clamp the sample on the air inlet of the fabric breather, and then adjust The speed of the fan makes the two sides of the fabric reach the specified pressure difference, and the air permeability of the fabric is determined according to the nozzle aperture and the pressure difference between the two sides. Air flow, unit (mm/s), and the performance of the air through the fabric when there is a pressure difference on both sides, which is called air permeability. Main parameters: 1. Pressure range: 1～4000Pa; 2. Measurable air permeability: 1～40000mm/s; 3. Measurement error:≤±2%; 4. Measurable fabric thickness: customized according to the sample; 5. Suction volume adjustment: data feedback dynamic adjustment; 6. Sample area setting circle: sponge clamp; 7. Clamp size: 100mm*100mm. Operation method: 1. Prepare the sample as required and cut it to the specified size. 2. Check the calibration equipment. 3. Turn on the power switch, set the test parameters on the control panel interface, and enter the test test preparation interface after setting. 4. Install the sample, put the sample into the detection area, and clamp it on the sample round table. The test position should avoid the edge of the cloth and the crease. When clamping the sample, a certain tension should be used to make the sample flat and not deformed. . To prevent air leakage, a gasket can be placed on the low pressure side of the sample. 5. Press the start button to start the automatic test. The suction fan is started to make the air pass through the sample. When the pressure drop gradually approaches the specified value, the air flow can be automatically recorded. 6. After the test is completed, press the test head to press the plate to release the clamping sample. Place the next test position of the sample in the detection area, press the test head platen to clamp the sample, press the start button, and start the test again. 7. Repeat the above operation until a set of samples is completed. Under the same conditions, repeat the test for different parts of the same sample at least 5 times. 8. After the test, you can query through the test panel, you can query and browse the results of each test in turn, and display the average value of the test. In case of air leakage from the fixture, the air leakage can be measured and removed from the data. 9. Press the test platen to release the gripper to avoid fatigue. Power off the instrument, unplug the power plug, and cover the instrument with a dust cover.
textile testing equipment tensile tester manufacturers, as the name suggests, find extensive use in tensile tester manufacturers institutions. Since tensile tester manufacturers has become much dependent on technology in today's world, there is wide use of such textile testing equipment.
GESTER International Co.,Limited’s core aim is to afford high-quality products with the concept of manufacturing technology.
The stability of the system, controllability of the tensile tester manufacturers process, and mobility of the machines provide with a flexible and reliable textile testing equipment system.
The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
