Abstract
A method for deactivating preferably odor-relevant molecules that is distinguished by the following steps is proposed: generating a plasma; deactivating preferably odor-relevant molecules by the effect of hot electrons of the plasma on the molecules to be deactivated.
Claims9
A method for deactivation of odor-relevant molecules associated with a material to be treated, said method comprising the following steps:
- providing a plasma source comprising an electrode and a counter-electrode, wherein the electrode and the counter-electrode are spaced apart from each other by a dielectric and face a same side of the material to be treated at a distance of 0 to 4 mm;
- igniting a discharge so as to generate a plasma at the distance of 0 to 4 mm from the side of the material toward which both the electrode and the counter-electrode face;
- and
- applying to the odor-relevant molecules hot electrons of the plasma so as to deactivate the odor-relevant molecules by an electron dissociation mechanism which alters molecular structures of the odor-relevant molecules, wherein:
- (a) the hot electrons are electrons that have an average kinetic energy of at least one electron volt, and (b) the material to be treated is a textile material.
