WWF (World Wildlife Fund) is concerned about a chemical added to clothing, this is called PFC (perfluorinated chemicals) which include the non-stick additive Teflon. These chemicals are increasingly being added to clothing because it makes them last longer and also can make them wrinkle-free. most clothing labelled "no-iron" contains PFCs. They say these PFCs are cancer-causing compound. However, "no-iron" and "wrinkle-free" pants have become a popular part of many schools' compulsory uniforms.. Hardly the thing you like to send your child off to school in. Without knowing it, parents are exposing their children to toxic chemicals in clothing that could have serious future consequences for their health and the environment.
Do some research yourself and see what you come up with.
