PRATO – A new study from an Italian-based testing laboratory claims that a routine test for the presence of PFAS in textiles – designed to meet tough new regulation such as California AB 1817 – is badly flawed.
The problem is that the ‘untargetted test’ which aims to measure the total organic fluorine content of an item gives ‘false positives’ if certain classes of reactive dyes are used to dye cotton fabrics.
