The penetration of a woven fabric by corona discharge is of paramount importance for the achievable result of its modification. It was examined how the fiber top layer structure of polyester woven fabric was changed because of its treatment with corona discharge under atmospheric pressure. The corona discharge used was generated with the use of an original generator equipped with a set of multisegmental electrodes that made it possible to obtain a required level of activation energy in successively supplied “portions,” which simultaneously prolonged the time of plasma impact. Changes in the topography of fiber top layer were examined by the AFM method. It has been found that this corona discharge can shape the fiber top layer in a qualitatively similar way as in the case of polyester films (characteristic globular structure). It has also been established that the achievable effect of modification is not limited exclusively to the fibers that form the external surface of the fabric activated, but it also affect, though to different extent, the fibers from various areas of the fabric structure. © 2010 Wiley Periodicals, Inc.
