You may not think of, after play basketball or play soccer, your jerseys will send out a disgusting smell.
According to a new study published in the journal , the stench is real, and there is a reason.
Volunteers were asked to smell the cotton and polyester T-shirt that healthy people wear in the last 1 hour strenuous exercise, but not the sweat shirt have "fermented" after 28 hours .(Let hot sweat shirt has time to make fatty acids break down into smaller molecules in the air, so people will smell smell.)
According to the results,the smell of the polyester T-shirt is more unpleasant than cotton T-shirt, the researchers used a microscope to observe the fabric, in order to find out why.They found that micrococcus is to be blamed that make sweat smell, it grows faster in polyester T-shirt than in the cotton.
The reason may be the man-made fiber can't absorb moisture, but they are stored.Now, the research team are trying to determine exactly why polyester fiber is the refuge of micrococcus.
