Air Permeability Tester TF164B

5 out of 5 based on 3 customer ratings
(3 customer reviews)

This Air Permeability Tester is used to test the resistance of the flow of air through fabrics such as woven or non-woven textile materials as well as knitted clothes under a constant air pressure.

Application

Air Permeability Tester, to test the resistance of fabrics (woven, knitted and non woven textile materials) to the passage of air (air flow) under constant pre-set air pressure while firmly clamped in the test rig of selected test head/area.

The specimen is loaded to the test area of the instrument easily by means of an automatic holder. By pressing down the holder to start the test. Aih’jr permeability tester equipped with a vacuum pump to draw air through an automatic interchangeable test head with a circular opening. The pre-selected test pressure is automatically maintained, and after a few seconds the air permeability of the test specimen is digitally displayed in the pre-selected unit of measure on the touch panel, or the next test nozzle required to be replaced will be displayed. After test the holder is released and the vacuum pump will be shut off.

Q: What’s the air permeability definition?

A: The fabric air permeability is to measure the volumn of air flow through it. The ease or passage of air plays an important role in end uses of many fabrics, such as industrial filters, tents, sailcloths, parachutes, raincoat materials, shirtings, downproof fabrics and airbags.

Air permeability refers to the volume of air per ml which passes the fabric at a speed of 1s or 10s/mm^2 in a pressure difference of 10mm water head.

 

Q: What is the air permeability test of textile fabric?

A: In British standard test, the volume of airflow through a specified area is measured at a certain pressure across the fabric with 10mm water head. Test sample is clamped over the inlet of device with rubber gaskets, and air is sucked through it by pumps, which is shown in Fig.A. The air valve is adjusted to exert pressure on air going through fabric of 10mm water head, then a flow meter is used to measure airflow.air permeability test

Q: What is the 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
