Description

Features of Auto Water Vapour Permeability Tester TF165B

The test results are more reliable. The test uses high-precision temperature and humidity sensors. It also uses a rotating sample holder with adjustable speed. This ensures that water vapor evenly affects each sample during the WVTR test.

It reduces cost and improves efficiency. It uses a double-layer rack with 9 test cups per layer. This setup boosts water vapor permeability test samples by a large margin.

The holder of this WVTR Tester is designed with two small doors for sample putting. This avoids impacting the test environment after opening the door. The tester also has automatic water filling for long-term testing.

It is easy to operate. It has chip control and color touchscreen operation. It also has a modular design and intelligent control. It displays test time in real-time. All of these features contribute to a perfect performance water vapor permeability tester.

Application of Auto Water Vapor Permeability Tester TF165B

Waterproof and Moisture-permeable fabrics are more and more popular. It keeps the sweat from building up and condensing between the body and the fabric. It keeps the garment comfortable. It is a high-tech and unique functional fabric. Waterproofing is easy for normal fabric. The key is to improve water vapor permeability. Testing for Moisture Vapor Transmission Rate is becoming more important in textiles.

The TF165B is an Auto Water Vapour Permeability Tester. It measures the water vapor permeability of fabrics. It works on many fabrics. These include coated ones that let moisture through—also, wadding tires, space cotton, and other nonwoven garment fabrics.

The fabrics are waterproof and let water vapor through. They are used to make military and protective clothing. Now, they are widely used to make sportswear, travel bags, tents, etc. Waterproof, vapor-permeable fabrics can also be used as trauma dressings. They are like cotton gauze. They keep wounds dry. They are also used as surgeons and dustproof work clothes in the clean studio.

Test Principle of Water Vapor Transmission Rate Testing.

In a constant temperature and humidity test room, we place the permeable cup. We put the specimen in the cup and seal it with a rubber gasket. We then place the permeable cup with water and fabric in the sealed room. The room has the specified temperature and humidity. We calculate the permeable amount by measuring the change in the cup’s quality. The cup includes the specimen and moisture absorbent or water. This change occurs 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.

    Q: What's water vapour permebility definition?

    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.
