In the textile industry, air permeability is a crucial indicator of fabric comfort and performance. The GT-C27A Efficient Air Permeability Tester is specifically designed to test the air permeability of various fabrics, including woven, knitted, non-woven fabrics, and industrial filter materials. This article provides a detailed guide on the operation of the Automatic Air Permeability Tester and its applications in textile testing.
The GT-C27A Air Permeability Tester is a professional instrument designed to evaluate fabric performance by measuring air permeability. The device comes with standard accessories, including 20cm² and 38.3cm² testing fixtures, with the 38.3cm² fixture being commonly used. The instrument must be connected to compressed air with a pressure of approximately 0.6Mpa to ensure stable operation.
1. Start the Device
First, connect the device to compressed air, ensuring the pressure is about 0.6Mpa. Turn on the power and prepare for testing.
2. Install the Fixtures
Installing the fixtures is a critical step in the testing process:
- Place the lower fixture in position.
- Lock the upper fixture onto the holder and connect the air pipe.
3. Set the Parameters
Press the "SETTING" button to enter the setting interface. In this interface, perform the following operations:
- Set the test parameters: select the test nozzle (0-10), set the test pressure, and the test time. Note that other parameters should remain unchanged.
- Click the "TEST_INF" button to enter the test interface.
4. Select the Nozzle and Start Testing
4.1 Return to the test interface and click the "TURN N." button; the nozzle will automatically switch to the set number. The button will then change to "TEST."
4.2 Place the specimen and click the "TEST" button to start the test.
During the test, the progress bar will show the test progress, with two possible outcomes:
4.2.1 If the progress bar exceeds 90% and no pressure is displayed, it indicates that the nozzle is not suitable and a larger nozzle number is needed.
4.2.2 If the progress bar is below 20%, a smaller nozzle number is required.
5. Adjust the Nozzle Number
Based on the test results, enter the setting interface to change the nozzle number, then return to the test interface and click the "TURN N." button to switch the nozzle number automatically. Repeat these steps until the progress bar stabilizes between 20-80%.
6. Conduct the Formal Test
Use nozzle number 6 for the test, ensuring the progress bar stabilizes around 46%, indicating a normal test.
Record the displayed data and, upon completion, click the "PRINTEALL" button to print out the data.
Upon completion of the test, the GT-C27A Air permeability testing equipment provides detailed test data, helping users evaluate the air permeability of fabrics. This data is essential for fabric research and development, quality control, and performance evaluation. By analyzing the test data, users can understand how different fabrics perform under various conditions, optimizing product design and manufacturing processes to enhance market competitiveness.
The Air permeability tester for fabric, with its precise testing capabilities and user-friendly operation, is an indispensable tool in the textile industry. This detailed guide helps users understand and operate the device better, ensuring accurate and reliable results in fabric air permeability testing.
