All Waterproof Jackets to PFAS-Free
About PFAS
PFAS refers to a group of synthetic organofluorine compounds, encompassing more than 10,000 substances.
They are used in a wide range of applications due to their excellent water repelling and oil repelling properties and are also widely used in clothing as water repellent agents. Among organic compounds, however, PFAS are characterized by a strong carbon-fluorine (C-F) bond which makes them highly resistant to degradation in natural environments. For this reason, they are often referred to as “Forever Chemicals,” and it is thought that some PFAS could have harmful effects on the human body.
Because of these concerns, PFAS compounds are increasingly regulated on a global level to protect human health and the environment.
About Water and Oil Repellency
Water-repellent agents traditionally contained PFAS, but now PFAS-free agents which offer the advantage of reducing adverse effects on the human body and the environment have been developed. Unlike conventional PFAS agents, however, they have very low oil repellency, which makes it more difficult to prevent oil-based staining, which can lead to a reduction in water repellency.
Recovering Water Repellency
When water repellency is impaired due to staining, it can be restored through a washing and drying process. The stains initially are removed by washing, though use of fabric softener should be avoided. They should then be dried using a household clothes dryer or hung to dry in the shade. Since applying heat is important for restoring water repellency, if dried in the shade, it is recommended this be followed by about 15 minutes in a household clothes dryer at a low temperature (below 60°C).
