Ozone and Atmospheric Pollutant Resistance
topic
Ozone exposure testing subjects fabric specimens to defined ozone concentrations in controlled humidity and temperature chambers for standardised durations, measuring colour change, tensile strength loss, and surface cracking in elastane, dyed nylon, and treated cotton fabrics susceptible to atmospheric ozone degradation at concentrations found in urban environments.
Role
Addresses a specific degradation pathway relevant to elastane-containing sportswear and dyed nylon swimwear where ozone attack on double bonds causes irreversible discolouration and fibre embrittlement, guiding antiozonant treatment selection and dye chemistry choices for urban outdoor textile applications.
