AATCC TM216-2024, Test Method for Measuring the Odor Adsorbency of Textile Materials Using a Representative Malodor of Human Origin

2.    Purpose and Scope

2.1 This test method provides a quantitative procedure for the evaluation of the degree of odor adsorbent activity on tex-tiles as measured by the reduction in iso-valeric acid concentration near a treated sample relative to a reference. This method provides guidance on measurement of odor adsorbent activity of a textile finish once it has been applied to a textile rela¬tive to a reference textile of identical composition but without the added finish as different textile substrates often demonstrate different inherent odor adsorption properties.

2.2 This method also provides guidance for modifying both the concentra¬tion (ppm) and amount (volume) of odor added to demonstrate significant differences between treated and untreated control samples. Since the odor adsorbent activity of a fabric is often due to the addition of multiple finishes, textile substrate, composition or design, the odor adsorbent properties for the entire textile may be evaluated. This is often ideal when an identical untreated fabric is not available. This quantitative evaluation provides an opportunity to measure the benefits of different additives or designs that may promote or decrease the odor adsorbency of a textile. Combined with other assessments, it provides a clearer picture for possible uses of treated textiles for the prevention or reduction of malodors.
