Material treatment is effected in a treatment region by at least two energy sources, such as (i) an atmospheric pressure plasma and (ii) an ultraviolet laser directed into the plasma and optionally onto the material being treated. Precursor materials may be dispensed before, and finishing material may be dispensed after treatment. Electrodes (e1, e2) for generating the plasma may comprise two spaced-apart rollers. Nip rollers (n1, n2) adjacent the electrode rollers define a semi-airtight cavity, and may have a metallic outer layer. Loose fibers and fragile membranes may be supported on a carrier membrane, which may be doped. Individual fibers may be processed. Electrostatic deposition may be performed. Topographical changes may be effected. Various laser configurations and parameters are disclosed. |
