According to http://www.lewcospecialtyproducts.com/Files/Press/K90.pdf In Human data testing kevlar could Cause Skin irritation,
Skin sensation has not been observed in human skin tests. The mechanical action of the fibers may cause slight skin irritation at clothing binding points and mild irritation of the eyes and nasal passages. Overexposure to the respirable fibers by inhalation may cause mild and temporary upper respiratory irritation with discomfort or cough. Based on animal testing, prolonged and repeated exposure to excessive concentrations may cause permanent lung damage.
