Air Permeability is a test which is done a lot to determine how much air can pass through any fabric. It measures the different types of permeability in any material. Air permeability defines how easily air or water passes through a material – in simple words, it tells us how much air can pass between 2 surfaces of material when some force is applied.
For easy understanding remember that the rate of airflow is measured by the term “air permeability”; this then shows you how well air can go right through the material given pressure difference – generally it is measured against time and collected in cubic centimeters, hence telling you the amount of air passing through a 100 cm square of the intended fabric sample within one second at pressure difference being 10 cm of water.
Air permeability is mainly affected by the density of the shape, value, or structure of the fabric or thread. Air permeability means how easily air can pass through a fabric. The quality and texture of clothing influence air permeability, but air permeability is also influenced by chemicals and coatings that are applied to the surface of clothing or used in the production of fibers.
For chemicals, we generally mean any preparation or substance that affects the flow of an external medium (e.g. liquid, gas). This could be a physical treatment but might also include specific kinds of finishes. For example, an anti-perspiration finish for sportswear purposefully slows down the perspiration process.
Coatings are normally liquids that are applied on one side of the fabric to achieve specific functional properties e.g. absorb water repellent. Coatings completely block airflow through this part if they are dense enough. An air permeability tester ensures how much air and moisture can pass through the fabric. There are many clothes which are designed in such a way that protect from wind and moisture like a raincoat. This tester makes us feel secure with our comfortable dress.
Air permeability tester has many different features. The first feature is that this tester has a 7-inch touch screen so that you can easily control it and at the same time you can also use it by connecting it to a computer. This tester works in full range and identifies the samples, which makes the testing process very easy and fast.
The shape of the test head of the Air permeability tester works in such a way that you do not need to measure it later. This tester uses high-precision pressure and differential pressure transducers, which collect correct data. It cleans the hole plate of the tester so that both clarification and cleanliness are maintained in this testing process.

The air permeability tester comes with a thermal printer, which prints the testing results very easily. At the same time, it uses computer programming, whose testing results can be shown directly without manual calculation. This tester comes with different types of testing units, such as mm/s, m3/m2.min, cm3/cm2.s, etc., which can test many types of samples.
The Air permeability tester has an air-controlled tester arm so that samples can be held or pressed. Not only this, but this tester has 11 types of nozzles and calibers, which can test samples of any material in many ways.
The testing time of the Air permeability tester is about 10 to 15 seconds, in which the difference of nozzle pressure is 4000Pa and the specimen pressure difference is 1000Pa.
The permeability range of the Air permeability tester is 0.1 to 12000 mm/s. The thickness of its fabric is ≤12mm. The weight of this tester is 93 kg. It has a power supply of 220V 56/60 HZ, 2KW and the dimension of this tester is 1020×460×1016mm (L×W×H).
The air permeability tester is very easy to operate. It can be started with just one click. It is an excellent tool for continuous tests. Calculations can also be done in it. It can also be connected to Wi-Fi, and Wi-Fi connection and data transmission are very quick and easy. Its operation is very easy with a colorful touch screen. No kind of human error is found in it. It can be operated smoothly and easily.

Q : What is an air permeability tester?
A : Air Permeability is a test which is done a lot to determine how much air can pass through any fabric. It measures the different types of permeability in any material. Air permeability defines how easily air or water passes through a material.
Q : What is good permeability?
A : When liquid or gaseous substances such as water or air flow easily through any material, be it soil or cloth, then it is called good permeability. This depends on the size of the pores of the material particles and how they are connected to each other.
Q : What if the permeability is high?
A : When the ability of passing the air in any material is high then any flow like gas or air easily flows through the material. Like the cloth which has high permeability the air and water can easily pass through that cloth.
Q : What are the two types of permeability tests?
A : Two permeability tests are there which can be performed in the laboratory. These two tests are the constant head test method and the falling head test method.
