Fabric Moisture Permeability Tester
Fabric Moisture Permeability Tester
A Fabric Moisture Permeability Tester, also known as a Water Vapor Permeability Tester, is a laboratory instrument designed to measure the rate at which water vapor passes through textile materials. This measurement is crucial for assessing the breathability and comfort of fabrics, especially those used in active wear, outdoor gear, medical textiles, and protective clothing.
Purpose of Fabric Moisture Permeability Tester
The primary function of this tester is to evaluate a fabric’s ability to allow moisture vapor to pass through it, which directly impacts the wearer’s comfort by facilitating sweat evaporation and thermal regulation. High moisture permeability indicates better breathability, making the fabric suitable for applications where moisture management is essential.
Working Principle of Fabric Moisture Permeability Tester
The tester operates by placing a fabric specimen over a container filled with water. Under controlled temperature and humidity conditions, water vapor passes through the fabric over a specified period. The amount of water vapor transmitted is determined by measuring the weight loss of the container, allowing for the calculation of the Water Vapor Transmission Rate (WVTR).
Common Testing Methods
- Upright Cup Method: The fabric covers a cup containing water, and the assembly is placed upright in a controlled environment. After a set duration, the weight loss is measured to determine the WVTR.
- Inverted Cup Method: The fabric is sealed over a cup, which is then inverted and exposed to a controlled environment. The amount of water vapor absorbed by the fabric is measured over time.
- Sweating Hot Plate Test: Simulates human perspiration by measuring the energy required to maintain a constant temperature on a heated plate covered with the fabric, providing insights into the fabric’s breathability.
Key Specifications of Fabric Moisture Permeability Tester
– Test Cups: Typically 6 to 8 cups, each with a diameter of approximately 83 mm and a depth of 18.5 mm.- Turntable Speed: Approximately 2 revolutions per minute (RPM) to ensure uniform exposure.
– Environmental Conditions: Tests are conducted under controlled temperature (e.g., 23 ± 2°C) and humidity (e.g., 50 ± 5% RH) settings.
– Standards Compliance: Conforms to international standards such as ASTM E96, ISO 15496, BS 7209, and JIS L1099.
✅ Benefits of Fabric Moisture Permeability Tester

- Mount the Fabric – Cut the fabric into circular pieces matching the cup size.
– Securely seal each fabric over the cup opening with a gasket and ring to prevent leakage.
- Weigh the Cups – Record the initial weight of each cup with the fabric mounted.
- Place on Turntable – Position all cups on the rotating tray inside the controlled chamber.
- Set Conditions – Close the chamber and maintain temperature (e.g., 23°C) and relative humidity (e.g., 50%) as per test standard.
- Start the Test – Begin rotation (usually ~2 RPM) and let it run for the specified time (often 24 hours).
- Weigh the Cups Again- After the test duration, reweigh the cups to determine weight loss due to moisture vapor passing through the fabric. Calculate WVTR – Use the formula: WVTR = (Weight Loss in grams × 24) / (Test Area in m² × Time in hours) Expressed in g/m²/24h.Clean and Store – Clean cups and components for future use.
