New University of Alberta research now shows why. Analysis of various fibers soaked in a solution of simulated sweat showed that cotton and viscose, which are cellulosic, or plant-derived fibers, absorbed—and consequently released—smaller amounts of odor-causing compounds than polyester , nylon and wool.
The key finding from the study , published in the Textile Research Journal , explains why some commonly worn fibers are smellier than others when people sweat, says Rachel McQueen, a clothing and textiles scientist in the Faculty of Agricultural, Life & Environmental Sciences who conducted the research with colleagues from the University of Otago in New Zealand. "Although we know that polyester is smellier after being worn next to sweaty armpits compared to cotton T-shirts, we haven't really known why. Now we have a better understanding of how odorants transfer and are selectively absorbed by various fiber types in sweat.
" The study's method of using simulated liquid sweat also offers an important fresh approach to exploring the issue, she notes. "Body odors commonly transfer to clothing through liquid sweat, but invest.
