What Is an Air Permeability Tester and How Does It Work?
In industries, safety matters because when air moves through particles and material then air permeability is used in sportswear, filtration and textile and play important role in functionality and quality. Air permeability testing is the main reason is to check quality of fabric and other materials. Air flow measurement is helpful for manufacturers to check quality, suitability, performance and durability.
What is air permeability testing?
Air permeability is specific rate in which air passes through porous material and fabric when specific pressure applied over cloth. In textile industries, it is helpful in measurement of breathability, insulation and comfort.
Example
For ventilation, sportswear is important clothes so it is compulsory to check its breathability
Jacket which is used in winter require lesser permeability so it gets warmth easily.
As we know, in medical industries mask play important role there air permeability check airflow.
If it is not checked through permeability tester, then manufacturer do not even know whether this fabric fulfill its required purpose or not.
What is air permeability tester?
A test that is conducted through air permeability machine in which we can measure volume of air flow from a material within difference of pressure and a set time. This type of data is repeated over time, so it support innovation because when a product is going under testing, then good research is conducted.
Development of a product can also be assured through a tester. Every international standard is considered when it is time to check quality, so it is important.
How it works?
In testing, it is important that everything should be precise and straightforward.
Process
Placement of the sample
Sample is checked properly before it is clamped into the machine because any leakage can easily affect the result. After that, it is proceed with accuracy.
Applied controlled air pressure
When pressure is applied in a controlled and constant manner on the sample, it helps in checking the strength of the fabric that it is breathable or long lasting survival fabric.
Measurement of air flow
Sensor present in the machine that responds when air passes through fabric and shows breathability.
Display of the result
Result is most important because it help manufacturer to choose better quality material. If the fabric quality is not up to expectation, then it become loss for the manufacturer, so before choosing any stock, this test should be applied on a sample.
Why this test is important?
This test is not only like any laboratory testing that enhance satisfaction of customer and performance is also affected. If fabric breathability is important, then when it is checked under a machine, it becomes comfortable.
Product quality matters, and it is not easy to maintain, but it can be easily detected through an air permeability tester. International standard also compulsory, so machines play an important role to follow that standards.
Innovation and R&D are supported because measurement is helpful to check. Production error reduction is helpful, and the chances of error are reduced.
Application
Apparel and textile industries
In textile fabric play an important role because fabrics used regularly then fabric loose elasticity and also fade over time. If the manufacturer uses this tester, then it can calculate the survival of fabric with time and quality improvement.
Industrial material
Under various controlled pressure condition industrial material capacity was checked. Their permeability testing is helpful to check the capacity for further conditioning.
Filtration
It is a process in which everything is checked under controlled pressure, so the air flow shows filtration accuracy.
Medical industry
In the medical industry mask and lab coats play an important role, and the breathability of these materials can be tested.
Automotive industries
In this industry, everything should be perfect because air permeability testing is helpful to check the quality of material which used in interior fabric and seat cover. This is checked before installation, so it guarantee long time use and a better product for the customer.
Is breathability the same as air permeability?
At the technical level, both are different, but they are used interchangeably.
Breathability
Moisture transmission through vapour and how vapour escapes.
Air permeability
It measures how air passes through material or fabric.
Both are important for different purposes and different instrument used to fulfill requirement of the manufacturer.

FAQ
Q: What do you mean by air permeability testing in the textile industry?
A: When fabric passes under controlled pressure, it helps in the evaluation of comfort, insulation and ventilation.
Q: Why this test is important?
A: This testing verifies fabric performance for winter clothing innovation in textile and technical materials.
Q: How many units are used in the measurement of air permeability testing?
A: cm3/cm2/s, cubic feet per minute and other units depend upon industry type.
Q: Is it equal to breathability?
A: No moisture vapour detected differently and air permeability detects how breathable the fabric is.
Q: Write the standard used in air permeability testing?
A: DIN 53887, ISO 9237, ASTM D737 and BS 5636.
