<p>The present invention provides a method of making a nonwoven web with desired fiber orientation, the method including the steps of providing a source of fibers, subjecting the fibers to an electrostatic charge, deflecting the fibers with a non-contacting deflecting device, collecting the fibers on a moving forming surface to form the nonwoven web. The invention also provides an apparatus for forming fibrous nonwoven webs, the apparatus comprising a source of fibers, a device for applying an electrostatic charge to the fibers, a non-contacting fiber deflecting device adapted to affect the fibers while the fibers are under the influence of the applied electrostatic charge, and a forming surface for collecting the fibers as a fibrous nonwoven web.</p> |
