Textile Air Permeability Tester

Meet the standard:

ASTM D737

ISO 9237

EDANA WSP 070.1

JIS L1096

Product Introduction:

Air permeability is defined as the volume of air that passes through a unit area of a textile fabric in a given time under a prescribed pressure difference across the fabric. A Textile Airflow Resistance Tester provides a quantitative measure of this property.

The testing process involves clamping a specimen of the textile fabric into a test head, ensuring that the area surrounding the test region is sealed. A controlled airflow is then directed through the fabric, typically by using a vacuum pump to draw air through the specimen or a pressure source to push air through.

The instrument maintains a constant, specified pressure difference across the fabric specimen. Simultaneously, the volume or rate of air passing through the fabric is accurately measured by a flow meter.

The air permeability is calculated automatically by the instrument's software based on the measured airflow rate, the test area of the specimen, and the applied pressure difference, and is typically reported in units such as cubic feet per minute per square foot (ft³/min/ft²), cubic centimeters per second per square centimeter (cm³/s/cm²), or liters per square meter per second (L/m²/s). The test is usually performed on dry, conditioned specimens. Different test heads with varying orifice sizes are available to accommodate fabrics with a wide range of air permeability.

The instrument is used in laboratories for:

Measuring the air permeability or airflow resistance of woven, knitted, non-woven, and coated textile fabrics.

Assessing the breathability of fabrics for clothing, sportswear, and protective wear.

Evaluating filter media performance based on air permeability.

Quality control during textile manufacturing to ensure product consistency.

Research and development of new textile materials with specific airflow properties.

Comparing the air permeability of different fabrics.

Product Advantages:

Provides objective, quantitative measurement of textile air permeability/airflow resistance.

Essential for assessing fabric breathability and openness.

Important performance parameter for technical textiles, filters, and apparel.

Standard compliant test methods (ASTM D737. ISO 9237) ensure reliable and comparable results.

Useful for quality control, material comparison, and product development.

Helps meet performance specifications for various textile applications.
