Odour Intensity and Character Assessment
topic
Textile odour assessment combines sensory panel olfactometric evaluation at standardised sniff distances under controlled conditions using trained panellists rating intensity on a six-point VDA 270 scale with descriptive character profiling, complemented by GC-olfactometry identifying individual odour-active compounds at their detection threshold concentrations in the vapour headspace.
Role
Addresses consumer complaints about chemical odours from new textiles, enabling identification of specific odour-causing compounds from finishing chemicals, solvents, and microbial degradation products, and providing the sensory data needed to reformulate finishing systems to meet automotive interior material and consumer textile odour acceptability thresholds.
