What is the Water Vapour Permeability of Fabric?
Water vapor 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 airside through the fabric. The water vapor permeability of fabric refers to the difficulty degree of water vapor passing through the fabric. The water vapor 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 vapor permeability test method.
Das Prinzip des Wasserdurchlässigkeitstests
A test specimen is sealed over the open mouth of a test dish that contains water, and the assembly is placed in a controlled environment. Following a period of time to establish the equilibrium of the water vapor pressure gradient across the sample, successive readings of the assembled dish are made and the rate of water vapor permeation through the specimen is calculated.
Wie berechnet man die Wasserdampfdurchlässigkeit?
The water vapor permeability index is calculated by expressing the water permeability of textiles as a percentage of the water vapor permeability of a reference fabric which is tested in a water vapor permeability test. After the water permeability test for the fabric, the water vapor permeability of the fabric can be obtained according to the water vapor permeability unit conversion and the water vapor permeability formula.
A1: Water Vapor Permeability (Breathability) is the ability of a fabric to allow moisture Dampf durch das Material übertragen werden. Es ist eine wesentliche Eigenschaft, die zur thermischen und physiologischen Komfortkleidung beiträgt, und ist bei der Filtration und bei medizinischen Textilien von entscheidender Bedeutung.
Q2: What is water vapor transmission rate testing (water permeability test for fabric)?
A2: Dieser Blog schließt weitere Informationen über die Wasserdurchlässigkeit. Sie finden es hier.
Q3: What is a good mvtr? And what is a perfect mvtr?
A3: For the moisture transmission rate (also known as Moisture Vapor Transmission Rate, MVTR) of textiles, the definitions of satisfactory and excellent differ for different applications and standards. Generally speaking, MVTR indicates the amount of water vapor allowed to pass through a textile within a certain period of time and is expressed in g/m²/24h. Below are some reference standards:
Moisture Permeability Standards for General Garments and Textiles:
General Clothing:
Qualified moisture permeability: 2000-5000 g/m²/24h.
Excellent moisture permeability: 5000-8000 g/m²/24h or more.
Outdoor clothing (e.g. mountaineering, skiing clothing):
Qualified moisture permeability: above 5000 g/m²/24h.
Excellent moisture permeability: above 10000 g/m²/24h.
Waterproof and breathable materials (e.g. Gore-Tex, eVent, etc.):
Qualified moisture permeability: > 15000 g/m²/24h.
Excellent moisture permeability: > 20000 g/m²/24h.
Beeinflussende Faktoren:
Usage: Moisture permeability standards may vary depending on the usage of the textile (e.g. sportswear, outdoor equipment, daily wear).
Environmental conditions: Temperature, humidity, and other environmental conditions will affect the test results.
Fabric structure and processing: Different materials and finishing techniques (e.g. coating, lamination, etc.) can significantly affect the moisture permeability.
In summary, specific moisture permeability requirements should be determined based on the end use of the textile and industry standards.

Q4: How many kinds of Water vapor permeability test methods?
A4: The following three methods are more common and practical:
1. Cup Method (Desiccant Method)
Principle: The test sample is covered with a cup containing desiccant or water, which is sealed and placed in an environment of constant temperature and humidity. Water vapor penetrates or escapes from the surface of the sample into and out of the cup, and the weight of the cup changes over time.
Calculation of the Water Vapor Transmission Rate: The Water Vapor Transmission Rate (g/m²/24h) is calculated by measuring the change in weight of the cup over some time.
Advantages: Easy to operate, suitable for different types of materials.
Disadvantages: Longer testing time and high environmental control requirements.
2. Water Vapor Transmission Rate Tester (MVTR Tester)
Principle: Using a specialized testing instrument, the sample is sandwiched between the wet and dry zones, the wvtr testing machine automatically controls the humidity difference and measures the moisture permeability by means of a sensor.
Calculation of Moisture Transmission Rate: The instrument automatically calculates the moisture transmission rate based on the humidity difference between the two sides of the sample and the amount of water vapor passing through.
Advantages: High precision, fast testing speed, suitable for different materials.
Disadvantages: Expensive equipment, complicated operation.
Test-Bedingungen:
Temperature: The standard test temperature is usually 23°C, but sometimes tests are conducted at different temperatures such as 38°C, 50°C, and so on.
Relative humidity: usually tested at 50% or 90% relative humidity.
3. Infrared Humidity Sensor Method (Infrared Humidity Sensor Method)
Principle: The test sample is placed between two chambers of the humidity sensor. One chamber is filled with moisture and the other is dry. Water vapor passes through the sample from the wet chamber to the dry chamber and the sensor detects the change in humidity in the dry chamber.
Water Vapor Transmission Rate Calculation: Using the sensor data, the rate at which water vapor passes through the sample is calculated.
Advantages: Faster testing, suitable for large-scale testing.
Disadvantages: equipment is more expensive, suitable for thin or have a certain degree of moisture permeability of the material.
Verwandte Standards:
ASTM E96: describes a variety of standard methods for testing moisture permeability by the cup method.
ISO 15496: specifies test methods for water vapor permeability of textiles.
GB/T 12704 (China National Standard): Specifies the test methods for moisture vapor transmission rate.
Each method has its own advantages and disadvantages, and the selection of a specific method needs to be weighed according to the nature of the textile and the actual application scenario.
Q5: Which textiles need water vapor transmission rate testing?
A5: Moisture permeability testing is mainly applied to textiles with strict requirements for breathability, comfort, and protection.
The following are some of the types of textiles that must be tested for moisture permeability:
1. Functional clothing fabrics
Outdoor clothing: Mountaineering clothing, skiing clothing, assault clothing and other outdoor sports clothing need to have good waterproof breathability to ensure that the wearer can sweat and stay dry during exercise.
Sportswear: running clothes, fitness clothing, etc., requires good moisture permeability to help dissipate heat and sweat, and enhance sports comfort.
2. Waterproof and breathable fabrics
Waterproof jackets and pants: functional fabrics such as Gore-Tex, eVent, etc. need to be both waterproof and breathable to provide good outdoor protection.
Protective Clothing: Certain specialized occupations (e.g., firefighters, chemical processing workers) require protective clothing with excellent moisture permeability to keep the body dry and comfortable, and to avoid excessive sweltering.
3. Medical Textiles
Medical protective clothing: including surgical gowns, isolation gowns, etc., which are required to protect against liquid penetration, but also breathable, to reduce the discomfort caused by prolonged wear.
Medical dressings: such as breathable bandages, etc., not only to prevent moisture or bacteria into the wound, but also to allow the skin to breathe.
4. Heimtextilien
Bedding: such as waterproof and breathable bedspreads, pillowcases, etc., especially for infants and young children or the elderly use of products that need to be waterproof and at the same time maintain breathability to avoid moisture accumulation.
Cushion and sofa fabrics: some household fabrics require good moisture permeability to ensure comfort.
5. Industrial textiles
Filtration materials: textiles used for air or liquid filtration require both prevention of particles or liquids from passing through and a certain degree of breathability to maintain filtration efficiency.
Tent and awning materials: textiles used for outdoor activities or temporary tents and other textiles that are both waterproof and have good breathability to avoid stuffy heat and humidity inside.
6. Schuhmaterialien
Waterproof and breathable footwear materials: such as outdoor shoes and sports shoes, the moisture permeability of the upper can enhance wearing comfort and help keep the inside of the shoes dry.
7. Baby and nursing supplies
Diapers and hygiene products: good moisture permeability is needed to prevent discomfort or health problems caused by prolonged exposure of the skin to moisture.
Baby carriers: fabrics that come into contact with the baby's skin need to be breathable to ensure the baby's comfort.
8. Military and Specialty Protective Equipment
Military clothing and equipment: Military equipment usually needs to have good Water Vapor Permeability to ensure the comfort and protection of soldiers in different environments.
These textiles have stringent requirements for Water Vapor Permeability in use scenarios, so water vapor transmission rate testing is a necessary step to ensure that they meet performance standards.
