Does Polyester Clothing Offgas?

Question from KER

Hi Debra, 

I was wondering if Polyester and other Petroleum based clothing give off VOCs? & if they do give off VOCs how long would it take to outgass them? 

Debra's Answer

Polyester and other synthetic fibers made from petroleum do offgass VOCs--chemicals that offgass are volatile, as in Volatile Organic Chemicals.

How long it takes for them to outgas depends on the fiber and the conditions and the amount of wash and wear. The VOCs decrease with time. I personally don't wear them at all, regardless of age.
