<p>A method and apparatus for charging fibers that contain a nonconductive polymer. A polar liquid (32, 34) is sprayed onto free-fibers (24), and the free-fibers (24) are then collected to form an entangled nonwoven fibrous web (25) that may contain a portion of the polar liquid. The nonwoven web (25) is then dried (38). By applying an effective amount of polar liquid (32, 34) onto the nonconductive free-fibers (24) before forming the nonwoven web (25), followed by drying (38), the individual fibers (24) become charged. The method and apparatus enable the fibers (24) to be charged during web manufacture without subsequent processing.</p> |
