 Fabric Air Permeability Tester

A Fabric Air Permeability Tester, also known as a Textile Air Permeability Tester or Fabric Porosity Tester, is a specialized instrument used in the textile and fabric industry to determine the air permeability of different types of fabrics and materials. The air permeability of a fabric refers to its ability to allow air to pass through it, which is an essential property for various applications.


The basic principle of the tester involves measuring the rate of airflow passing through the fabric under controlled conditions. This is usually done by subjecting the fabric to a constant pressure difference on both sides and then measuring the airflow through the fabric.


The main components of a typical Fabric Air Permeability Tester may include:


Test Chamber: A chamber where the fabric sample is placed and clamped securely to ensure a proper seal.


Pressure Differential System: A mechanism that maintains a constant and controlled pressure difference between the two sides of the fabric during testing.


Airflow Measurement System: It measures the rate of air passing through the fabric. The airflow can be determined using various methods, such as the orifice plate method, electronic flow sensors, or pressure sensors.


Control Panel: A user interface that allows operators to set testing parameters, start/stop the test, and view test results.


The testing procedure usually involves cutting a specific size sample from the fabric and placing it in the test chamber. The instrument then applies a pressure differential across the fabric and measures the airflow passing through it. The air permeability of the fabric is expressed in units such as cubic feet per minute (CFM) or liters per square meter per second (L/m²/s).visit Labtron.org.
