QINSUN Air Permeability Tester UI-TX20

QINSUN Air Permeability Tester UI-TX20

Air Permeability Tester for Textiles is designed to test textile fabric air permeability by testing the sample under specified pressure, test area and time to know the rate at which the airflow passes vertically through the sample.  The rate is expressed as the air permeability of fabric.

Air permeability methods include ISO 9237, ISO 7231, ISO 5636, BS 5636, ASTM D737, DIN 53887, JIS L1096, GB/T 5453, GB/T 13764, EN 14683, etc. It is suitable for testing textiles, fabrics, non-woven fabrics, facial mask, etc.


Qinyuan Instrument is a manufacturer and supplier of textile testing machines. Please contact us to know the price of the permeability tester.

1. QINSUN Air Permeability Testing Machine Features:

This air permeability testing equipment uses a high-precision pressure sensor instead of the water column pressure method.

Use microcomputer to process test data.

Pneumatically clamp and fix the sample, which is convenient and fast

It can be connected to a computer to automatically draw test data curves for easy observation.

Touch screen display, test parameter setting is convenient and fast, and test result viewing is convenient.

The main body of the Air permeability testeris made of steel plate and painted on the surface, which is beautiful, strong and durable.

The internal flow tube of the instrument is welded with seamless steel tube, which has good sealing performance and guarantees the accuracy of the test.

2. Air Permeability Test Principle

Under the specified pressure difference condition, the air flow rate that vertically passes through the specified area of the fabric within a certain time is measured for the air permeability calculation.

3. Fabric breathability test

In the case of textile fabrics, their breathability may directly affect their comfort. If the breathability of a fabric is too low, it can be hot and uncomfortable as body heat and moisture cannot easily escape. There are two main methods of material permeability testing: differential pressure method and isobaric method, of which the most widely used is the differential pressure method. the QINSUN UI-TX20 textile breathability tester uses the differential pressure method.
