The air permeability test for fabric measures the ease with which air passes through a fabric. It is commonly used to assess the breathability of textiles. Here’s how you can conduct the test:
Prepare the Fabric Sample:
The fabric sample is cut into a specified square (usually 100 cm2 or 38.8 cm2).
Set Up the Air Permeability Tester:
Set up according to the AirFicient Air Permeability Tester’s instructions, you can select air permeability units and air permeability test standards (such as ASTM D737, Din 53887).
Place the Fabric Sample:
Place the fabric sample on it, ensuring it covers the entire opening.
Start the Test:
Start the air permeability tester to initiate the test.
Measure Air Permeability:
The air permeability tester will measure the rate of airflow passing through the fabric under a specified pressure differential. The AirFicient is a smart instrument, it can be connected through WIFI with the SmarTexLab App installed in the smartphones, so you can monitor the test status.
Repeat for Accuracy:
It’s common to conduct multiple tests and average the results for accurate results.
Record the Results:
Record the air permeability value obtained from the tester. The AirFicient through the SmarTexLab can share test results with the quality control department to brand buyers.
Analysis of results:
Higher air permeability values indicate the fabric allows more air to pass through, suggesting better breathability. Conversely, the opposite is true.
