Description
Features of Auto Water Vapour Permeability Tester TF165B
More reliable test results: high precision temperature and humidity sensors, rotating sample holder with adjustable speed, ensuring each sample is evenly affected by water vapor during the WVTR test, and the test for water vapor is more reliable.
Reduce cost and improve efficiency: the use of a double-layer specimen placement rack, 9 test cups per layer, greatly increases the number of samples for a single water vapor permeability test.
Reasonable and scientific design: The specimen holder of this WVTR Tester is designed with two small doors for sample putting and avoidance of the impact on the test environment after opening the door; automatic water filling function, suitable for long-term testing.
Easy to operate: chip control, color touch screen operation, modular design, intelligent control, real-time display of test time. All contribute to a perfect performance water vapor permeability tester.
Application of Auto Water Vapour Permeability Tester TF165B
Waterproof and water vapor permeability fabric means that under certain pressure, water will not be immersed in the fabric, but the sweat emitted by the human body can be transferred to the outside world in the form of water vapor through the fabric, thus preventing sweat from accumulating and condensing between the body surface and the fabric to maintain the comfort of the garment. It is a high-tech and unique functional fabric. For ordinary fabric, waterproofing is easy to achieve, the key is how to present better water vapor permeability. Moisture Vapor Transmission Rate Testing is becoming more and more important in the textile industry.
Auto Water Vapour Permeability Tester TF165B is an instrument used to measure the water vapor permeability of various fabrics (including moisture-permeable coated fabrics) and wadding tires, space cotton, and other garment nonwoven fabrics.
Waterproof and water vapor permeability fabrics have been developed and used in the production of military and protective clothing, and are now widely used in the manufacture of sportswear, travel bags, tents, and so on. In addition, waterproof and water vapor permeability fabrics can also be used as trauma dressing, such as cotton gauze, which can keep wound skin dry, and as surgeon’s work clothes and dustproof work clothes in the clean studio, in addition to the above-mentioned uses.

Test Principle of Water Vapor Transmission Rate Testing
In a constant temperature and humidity test environment, the permeable cup is placed, the specimen is placed in the cup and sealed with a rubber gasket, then the permeable cup with moisture absorbent or water and fabric specimen is placed in the sealed environment of the specified temperature and humidity, and the permeable amount is calculated according to the change in the quality of the permeable cup (which includes the specimen and moisture absorbent or water) within a certain period.

What is Water Vapour Permeability of Fabric?
Water vapour permeability definition: In general, there is a water vapor pressure difference between the front and the back of the fabric, so the water vapor diffuses from the high-pressure air side to the low-pressure air side through the fabric. The water vapour permeability of fabric refers to the difficulty degree of water vapor passing through the fabric. The water vapour permeability of fabric is an important index to measure the comfort of clothing. Due to the difference of clothing environment, it is necessary to choose the appropriate water vapour permeability test method.
The Principle of Water Permeability Test
A test specimen is sealed over the open mouth of a test dish which contains water, and the assembly is placed in a controlled environment. Following a period of time to establish equilibrium of the water vapour pressure gradient across the sample, successive readings of the assembled dish are made and the rate of water vapour permeation through the specimen is calculated.
How to Calculate Water Vapor Transmission Rate?
The water vapour permeability index is calculated by expressing the water permeability of textiles as a percentage of the water vapour permeability of a reference fabric which is tested in a water vapor permeability test. After the water permeability test for fabric, the water vapour permeability of the fabric can be obtained according to the water vapor permeability unit conversion and the water vapor permeability formula.
A: Water Vapor Permeability (Breathability) is the ability of a fabric to allow moisture vapor to be transmitted through the material. It is an essential contributing property to thermal and Physiological Comfort clothing, and is vital in filtration and medical textiles.
