Ever noticed that a polyester T-shirt is smellier than a cotton one after you work out? New University of Alberta research now shows why. A study funded by the Natural Sciences and Engineering Research Council of Canada.
Analysis of various fibres soaked in a solution of simulated sweat showed that cotton and viscose, which are cellulosic, or plant-derived fibres, absorbed and consequently released smaller amounts of odour-causing compounds than polyester, nylon and wool.
