Most fabrics (and items made of fabric, i.e.: clothing, towels, sheets, etc.) are also sprayed with pesticides before being exported from their originating countries; countries that have very different laws regarding chemicals than we do here. Many pesticides are based on neurological toxins. The more interesting (and possibly, terrifying) study would test what chemicals are still present in new clothing.
Perhaps that tic in your eye isn't quite as innocent as you hoped.
