Acetaldehyde and Glycol Emission from Polyester
topic
Acetaldehyde and ethylene glycol emission from polyester textiles and PET-based bottle recycled fibres is measured by headspace GC-MS analysis of thermally desorbed specimens at 120 degrees Celsius, quantifying thermal degradation byproduct release that occurs during high-temperature heat setting and garment ironing processes encountered during textile manufacturing and consumer use.
Role
Addresses the occupational inhalation risk of acetaldehyde emissions from polyester heat setting operations and the potential consumer exposure to volatile PET degradation products released from heat-processed polyester sportswear, contributing to workplace air quality management and indoor textile emission assessment programmes.
