Judging the breathability of clothing fabrics can be achieved by conducting air permeability tests. The following is a common method for testing fabric air permeability:
1. Preparation tools: air permeability tester, test sample, timer.
2. Measurement steps:
a. Cut the test sample into a specific size, usually 10cm × 10cm.
b. Turn on the air permeability tester and place the sample on the air permeability test area of the tester.
c. Start the timer and record the duration of the test, usually 5 minutes.
d. When the test time is over, stop the timer and record the test data.
3. Analysis results:
a. The tester will measure the air flow passing through the sample within the specified time.
b. Based on the test results, the air permeability value of the sample can be obtained. The common unit is cubic meters per square meter per hour (m³/h/m²).
4. Comparative analysis:
a. The air permeability value obtained by the test can be compared with the air permeability value of common fabrics.
b. Judge the air permeability of the sample based on the required air permeability requirements.
It should be noted that different types of clothing may have different requirements for breathability. Therefore, depending on the specific situation and purpose of use, the test results of breathability should also be evaluated in conjunction with the use requirements. In addition, the breathability test is only a method to measure the breathability of fabrics. It can also be combined with other test indicators, such as moisture conduction, evaporation, etc., to comprehensively evaluate the breathability of fabrics.
