Test criteria

Several tests an be used depending on the product specification.

Antibacterial textiles

Efficacy against sweat odor producing bacteria test:

Based on the standard test method DIN EN ISO 20743 the antibacterial activity is determined against the skin-specific microbes Staphylococcus and Corynebacterium after 4 h of incubation.

Products that optimize odor release and retention

Release of sweat odor
A special sweat odor simulate (“artificial sweat”) is applied on the sample. The sweat odor intensity is assessed by trained odor panellists according to VDI 3882.

Binding capacity for sweat odor molecules
A radioactively labelled lead substance of odorous sweat is quantified on the fabric by means of scintillation measurement.

Products that optimize odor redution

Sweat odor field test

Samples are worn by a group of test persons in an application-specific activity (e.g. sports, work). Sweat odor intensity is then evaluated by trained panellists using an olfactometric sampling unit. The field test can thus prove an anti-sweat-odor effect from the consumer’s point of view.
