Accelerated Life Testing for Textile Durability
topic
Accelerated life testing applies elevated stress levels of temperature, UV irradiance, mechanical load amplitude, or humidity cycling to compress textile service life into practical laboratory test durations, using Arrhenius, inverse power law, or Eyring acceleration models to extrapolate accelerated degradation rates to predicted real-use condition failure times with associated statistical confidence bounds.
Role
Enables prediction of long-term textile material service life from practical laboratory test programmes, allowing outdoor fabric, geotextile, and technical textile product performance to be characterised against multi-year service life requirements without the years of real-time exposure data that would be needed for direct service life measurement.
