Bild zu: On the scent of sweat Hohenstein Institute optimises textiles with reference to smell

Image 2: Thermographic image showing how skin temperature, perspiration and development of odours are influenced by textiles. Garments with high levels of resistance to moisture permeability (left) cause increased levels of circulation during physical activity and elevated temperatures in the micro-climate of the skin, particularly the underarms. Perspiration and bacteria are absorbed by the textile and it begins to smell stale.
