Shaking off fluorochemicals from outdoor and protective clothing

Most treated clothing over-engineered for consumer purposes

31-Jan-2019

Rain-repelling fluorochemicals used in waterproof clothing can and should be phased out as unnecessary and environmentally harmful, textile researchers argue. And yet they remain the only effective option for medics and emergency service personnel. New research demonstrates how waterproofs using ...
