Abstract
The invention relates to a polymeric fabric comprising an outer functional layer having hydrophobic and oleophobic characteristics made of a first compound, and a second functional layer having hydrophobic characteristics made of a second compound, wherein the first and the second compound differ from each other. Further the outer functional layer at least partly coats the second layer. Additionally, the invention relates to a method of producing a polymeric fabric and an apparatus for producing a polymeric fabric.
Claims14
A polymeric fabric comprising
- a woven carrier layer;
- an outer functional layer having hydrophobic and oleophobic characteristics made of a first compound;
- and
- a second functional layer having hydrophobic characteristics made of a second compound,
- wherein
- the first and the second compound differ from each other,
- the second functional layer is arranged on the woven carrier layer,
- the outer functional layer is arranged on and at least partly coats the second functional layer such that the second functional layer is between the outer functional layer and the woven carrier layer, and
- the outer functional layer is a plasma nanocoating which is comprises per- and polyfluoroalkyl substances (PFAS) comprising only one, two or three C-atoms.
