Abstract
Apparatus for plasma processing of a continuous fiber, comprising a first and a second plasma torch. Each plasma torch comprises oppositely arranged electrodes to define a plasma discharge chamber between the electrodes. The plasma discharge chamber comprises an inlet and an outlet for passing a plasma forming gas between the electrodes. The apparatus further comprises an afterglow chamber in fluid communication with the outlets of the plasma discharge chambers, which comprises a substrate inlet and a substrate outlet arranged at opposite sides of the outlets of the plasma discharge chambers. A transport system is configured to continuously transport the fiber from the substrate inlet to the substrate outlet through the afterglow chamber. The substrate inlet comprises an aperture having a cross-sectional size substantially smaller than a cross-sectional size of the afterglow chamber. The outlets of the plasma torches face each other and exhaust plasma activated species into the afterglow chamber.
