Breathability describes a fabric‘s ability to allow air and water-vapour to permeate, preventing the accumulation of moisture. Breathable materials thus increase comfort in use and avert skin irritation, particularly in applications involving direct skin contact.
- Hygiene products & wound dressings: Breathable nonwovens allow the skin to breathe, increasing wear comfort whilst preventing an accumulation of fluids and skin irritation, particularly during extended use.
- Automotive: Breathable textiles in the car seat increase driving comfort, especially on long journeys.
- Construction industry: Permeable nonwovens contribute to the health of the occupants. They allow the walls of buildings to breathe when required. Simultaneously, they avert the accumulation of moisture, thus preventing structural damage and potential health issues caused by mould formation.
- Mattresses & bedding: Breathable materials allow for a restful and comfortable sleep.
- Fashion: Breathability is a vital function for product performance.
Breathability, also referred to as resistance to water vapour permeability, can be measured according to DIN EN 31092, respectively ISO 11092 using the thermo-regulatory model of human skin. Breathability indicates the rate at which perspiration is transported through the material.
