The Air Permeability Definition of Fabric

What is the permeability of air? Fabric permeability refers to the air permeability of fabric in the presence of pressure difference on both sides of the fabric, that is, the volume of air flowing through the fabric per unit and area per unit time under the specified pressure difference between the two sides of the fabric. Because pressure difference is a necessary condition for air flow, air flow in the fabric can only be produced by maintaining a certain pressure difference on both sides of the tested fabric.

The Importance of Fabric Permeability

Fabric permeability is an important factor affecting fabric comfort and service performance. For example, sportswear, cagoule and warm wear have higher requirements for fabric permeability, and some industrial textiles such as parachute and filter cloth have special requirements for fabric permeability. Only the fabric that conforming to the requirements of air permeability can meet the different needs of our life and production.

Testing Principle for Air Permeability

The sample is fixed to the test zone through the handle. By pressing the test head to begin the test, a strong aspirator pump begins to draw air through an interchangeable test head at a circular opening. After the preset test pressure is automatically started and maintained for a few seconds, the air permeability of the tested sample is displayed in a preset unit of measurement. Press the test head again for one second, the sample is released and the aspirator pump is closed.

Test standard for Air Permeability of Fabrics

The measurement of air permeability is based on the fixed pressure difference as the benchmark for the test. Because the pressure difference stipulated in the national test standards is not consistent, current the common test standards are the: ASTM D737, ISO 9237, GBT 5453, and JIS L1096. The test requirements for each method, test results and conversion between common air permeability units are shown below.

There are many standards for testing the air permeability of fabrics, and there are slight differences between the standards according to the size of the test area and the value of the differential pressure air permeability tester. The air permeability meter should carry out the test strictly in accordance with the regulations.

Conventional Operation Flow

  1. Prepare the samples as required and cut them into the required size.
  2. Check the calibration instrument.
  3. Turn on the power switch, enter the control interface to set the test parameters, and then enter the test interface.
  4. Place the specimen in the test area and clamp it on the test table. The test position should avoid from the edges and creases, and the specimen should be kept flat before clamping.
  5. Start the instrument and begin test automatically. The suction fan start and the air through the sample, when the pressure difference approaches the specified value the instrument will records the air flow automatically.
  6. Complete the test, press the test head, release the sample, and test the sample in different positions.
  7. Repeat the above operation to test a set of samples, after the test, query the results and display the test average.

Q: What is air permeability definition?

A: The air permeability of a fabric is a measure of how well it allows the passage of air through it. The ease or otherwise of passage of air is of importance for a number of fabric end uses such as industrial filters, tents, sailcloths, parachutes, raincoat materials, shirtings, downproof fabrics and airbags.

Air permeability is defined as the volume of air in millilitres which is passed in one second through 10Os mm2 of the fabric at a pressure difference of 10mm head of water.

 

Q: What is air permeability test for fabric?

A: In the British Standard test the airflow through a given area of fabric is measured at a constant pressure drop across the fabric of 10mm head of water. The specimen is clamped over the air inlet of the apparatus with the use of rubber gaskets and air is sucked through it by means of a pump as shown in Fig.A. The air valve is adjusted to give a pressure drop across the fabric of 10mm head of water and the air flow is then measured using a flow meter.

Q: What is unit of air permeability of fabric?

A: The formula is as follows:
K (gas) = Q / (ΔP × A)
Where: K( gas) – air permeability, m ^ 3 / m ^ 2 · KPa · h;
Q – gas flow, m ^ 3 / h;
ΔP – gas through the porous material produced by the pressure drop, KPa;
A – area of the sample’s test area, m ^ 2

 

Q: What is air permeability test procedure?

A: 1. Test the conditioned specimens in the standard atmosphere for testing textiles, which is 21 +/- 1°C (70 +/- 2°F) and 65 +/- 2 % relative humidity, unless otherwise specified in a material specification or contract order.

2. Handle the test specimens carefully to avoid altering the natural state of the material.
3. Place each test specimen onto the test head of the test instrument, and perform the test as specified in the manufacturer’s operating instructions.

3.1 Place coated test specimens with the coated side down (towards low pressure side) to minimize edge leakage.

 

4. Make tests at the water pressure differential specified in a material specification or contract order. In the absence of a material specification or contract order, use a water pressure differential of 125 Pa (12.7 mm or 0.5 in. of water).

 

5. Read and record the individual test results in SI units of permeability as cm^3/s/cm^2 and in inch-pound units of permeability as ft^3/min/ft^2 rounded to three significant digits.
5.1 For special applications, the total edge leakage underneath and through the test specimen may be measured in a separate test, with the test specimen covered by an airtight cover, and subtracted from the original test result to obtain the effective air permeability.

 

6. Remove the tested specimen and continue as directed in 10.3-10.5 until ten specimens have been tested for each laboratory sampling unit.
6.1 When a 95 % confidence level for results has been agreed upon in a material specification or contract order, fewer test specimens may be sufficient. In any event, the number of tests should be at least four.

    It seems to work well so far. The only reason I didn’t give it a 5 star rating is because I haven’t really had it long and am not sure yet how it will hold up throughout time. But like I said, it’s been great so far.
