Atmungsaktivität

Atmungsaktivität refers to the ability of a material to allow moisture vapor to pass through it. This property is particularly important in textiles and clothing, where it impacts comfort and performance. When the body produces sweat, breathability allows this moisture to escape as vapor, preventing the buildup of dampness against the skin. This helps regulate body temperature and reduces the feeling of being clammy.

The breathability of a fabric is typically measured by its moisture vapor transmission rate (MVTR), which indicates how much water vapor can pass through a square meter of fabric in 24 hours. A higher MVTR generally means better breathability. Factors influencing a material's breathability include its fiber type, weave structure, and any coatings or membranes applied to it. Natural fibers like cotton and wool are generally considered breathable, while synthetic materials can be engineered to enhance this property.

In outdoor gear, athletic wear, and even bedding, breathability is a key feature for user comfort and preventing overheating or chilling. Materials that are both waterproof and breathable, often achieved through specialized membranes, offer protection from the elements while allowing internal moisture to escape. This balance is crucial for maintaining thermal regulation and preventing discomfort during physical activity or in varying environmental conditions.
